House Climate and Ventilation
House climate and fresh air are decisive
for the well-being of both animals and
human beings.
The house ventilation system ensures:
• That the temperature and air humidity
are kept at the perfect level
• Fresh air
• No draught nuisances
• Minimised risk of illness
• A high survival rate among animals
• Conditions for uniform, high growth
throughout the house
• An environmentally convenient production
form
– All this to create a house climate that
provides optimum production results and
maximum financial profits.
Ventilation Systems
SKOV’s ventilation systems are combined
by the following basic elements:
• Air intake
• Air outlet
• Interlinking
• Climate control
Air Intake
Irrespective of the size, geometry or location
of the house, SKOV has a solution for
providing fresh air to the livestock house
at the lowest possible energy costs.
In order to ensure uniform distribution of
air in the entire house, air must be let in at
the correct height, direction, volume and
velocity.
At low outdoor temperatures, ventilation
is carried out to remove the harmful gases
that occur in the house environment,
e.g. CO 2
. The air is cold when it enters the
6

Climate Control
The control unit ensures efficient and achouse.
In order to prevent problems when
the air reaches the animal zone, it is mixed
to create the correct temperature and the
velocity is adapted to this.
When it is hot, ventilation is carried out to
remove the excess heat of the animals and
to create a cooling effect by ensuring air
movement around the animals.
Air Outlet
The location of the air outlet is decided
on the basis of the ventilation system and
building as well as whether ventilation
is to be carried out through roof outlets
and/or wall fans.
Interlinking
With a SKOV ventilation system, you are
sure to get a system in which the components
interact perfectly. Components
and materials are designed and adapted
exactly to the system in which they are to

LPV (Low Power Ventilation) is a ventilation
system used in temperate regions of the
world. The system is designed to ventilate
pig and poultry productions. LPV with
wall and ceiling inlets is a classic negative
pressure system which can be adapted to
most house types.
Air Intake
Fresh air is supplied through the DA
1200 wall inlet or the DA 1500 ceiling
inlet. During cold periods, fresh air is
directed towards the ceiling and is mixed
with the house air before it reaches the
animal zone. During hot periods, the air
is directed directly towards the animals.
Alternatively, air can be supplied through
DA 50 roof inlets.
Air Outlet
Air is let out through DA 600 or DA 920
outlet units. DA 600/920 was developed
to ensure a high output at low power

Combi-Diffuse Ventilation
This system is a ventilation system designed
for use in temperate regions of the
world. Combi-Diffuse ventilation is a negative
pressure system for pig production.
Air Intake
During cold periods, air is taken in through
the ceiling which has a constant opening
area with tiny holes or pores. This ensures
a low air velocity already when air enters
the house, thus preventing the risk of
draught nuisances in the animal zone.
During hot periods, the air intake is supplemented
with DA 1800 ceiling inlets to
ensure sufficient air velocity during the
hottest periods and thus a cooling effect
to maintain optimum production. Other
inlet types can be used as an alternative to
DA 1800 ceiling inlets.
Air Outlet

SKOV System
Combi ventilation is a ventilation principle
that ensures optimum climate for
the animals through adaptation to the
location, geometry, layout and production
of the individual house. Ventilation
with this type of system requires much
from the supplier of the system as correct
dimensioning and installation are
essential.
11

Equal Pressure Ventilation
The system can be used in temperate
regions of the world. Equal pressure
ventilation is suited for all types of poultry
and pig productions, especially for monoblock
houses or areas where the house is
exposed to strong wind effects.
Fresh air enters the house through roof
inlets and air is let out through chimneys
in the roof. Fans in both the air intake and
outlet ensure circulation of air into and out
of the house. The result is neutral pressure
(equal pressure) so that the entire house is
ventilated correctly.
Air Intake
Fresh air is taken in through the DA 40A air
supply unit that allows perfect distribution
of the air in the house thanks to individually
adjustable nozzles.
Air Outlet
Air is let out through DA 600 or DA 920
outlet units. DA 600/920 was developed

control and air distribution. The
system can be adapted to houses that
are very difficult to ventilate with other
systems due to their locations, air leaks,
wind effects, etc. Thanks to this system,
it is possible for the producer to produce
under such conditions.
13

Tunnel Ventilation
The system can be used in tropical regions
of the world. Tunnel ventilation is a negative
pressure system suited for poultry and
pig production.
Air Intake
Air is taken in through a tunnel opening at
one end of the building. The tunnel opening
can be with or without cooling pads.
Air Outlet
Air is let out through large gable fans located
opposite the air intake with cooling
pads in order to create a cooling air current
(chill effect) in the longitudinal direction
of the house. It is possible to achieve
a cooling effect of 10-25° C, depending on

SKOV System
Fresh air is taken in through wall inlets
during cold periods, thus creating
minimum ventilation to remove the
excess moisture and heat of the animals;
furthermore, the air velocity is kept at a
low level. During hot periods, fresh air
is supplied through a tunnel opening
to create a cooling air current in the
longitudinal direction of the house. Air is
let out through wall fans/chimneys during
cold periods and through gable fans
during hot periods.
17

Air Intake
The air inlet is an essential part of a SKOV
ventilation system. SKOV’s specialists have
many years’ experience in developing
well-functioning components for air inlets.
Several factors decide which type of air
inlet to choose in order to get the most
out of the ventilation system.
mum air current, even at low and medium
ventilation.
The DA 1800 ceiling inlet is an efficient,
additional air inlet bringing fresh air into
the house via the garret when it is very
hot outside. The inlet is designed for use in
houses with diffuse air intake.
DA 40A Air Supply Unit
DA 40A is an air supply unit with 12
individually adjustable nozzles for perfect
distribution of air in the house. DA 40A
reduces the risk of inconveniences caused
by draught. DA 40A is designed for use in
houses with equal pressure ventilation.
DA 1200 Wall Inlet
DA 1200 is a wall inlet which is easy to
adapt to different buildings. It is designed
to ensure optimum air current at all ventilation
levels. A group of DA 1200 inlets can
be opened differentiated, thus ensuring
uniform air distribution in the entire house
at minimum ventilation.
DA 1500/1800 Ceiling Inlets
DA 1500 is a ceiling inlet that allows control
of air volume, air velocity and air direction
in relation to temperature and house
layout. The design of the inlet flap means
that the air always flows along the ceiling.
The capacity of DA 1500 can therefore be
used to its full potential ensuring opti-
DA 50 Roof Inlet
DA 50 is a roof inlet used in houses requiring
air intake from the garret or from
above the roof. DA 50 is fitted with air split
baffles ensuring that air flows into the
house in several layers, thus providing a
high output at low air velocities. The inlet
is designed for use in houses with LPV
ventilation.
Rack & Pinion
Rack & Pinion is used to open/close the
tunnel opening in houses ventilated using
Combi-Tunnel/Tunnel ventilation. SKOV
delivers the critical components, including
various installation kits, to ensure optimal
functioning of the air intake.
18

Air Outlet
SKOV Components
In a SKOV ventilation system, air is let out
through chimneys or wall fans. SKOV has
many years’ experience in developing
sturdy, efficient and well-designed air
outlets with an extremely high output.
Different factors decide which air outlet to
choose.
SKOV’s air outlets are designed to ensure
a high air output at low energy consumption.
It is not enough that the individual units
are efficient in themselves, the interaction
between and total control of the units
are equally important aspects. Most SKOV
ventilation systems are therefore controlled
in accordance with the MultiStep®
principle which is capable of minimising
energy consumption while at the same
time ensuring optimum use of the fresh
air.
DA 600 and DA 920 Outlets
The DA roof outlets from SKOV are fitted
with fans. The design of the outlets is aerodynamic
to ensure optimum air output
at low energy consumption. DA 600 and
DA 920 are easy to install on the ridge or
the side of the roof. A stable, reliable and
tight installation is ensured if roof sheets
are used. The outlets are extremely sturdy
under all weather conditions.
Wall Fans
Wall fans are ideal as air outlets when additional
capacity is needed in large houses or
where large air volumes are required. When
the requirement for air exceeds a certain
level, one or more of the wall fans can be
connected to supplement the chimneys.
Alternatively, all air can be let out through
wall fans. Wall fans are often installed
in Combi-Tunnel and Tunnel-ventilated
houses in tropical/subtropical regions.
19

Interlinking
All parts in SKOV ventilation systems are
designed and chosen for the purpose of
optimising the entire ventilation system.
Connecting the components correctly
ensures perfect interaction and thus optimum
system performance.
The winch motor controlling the air inlet
and outlet is a key component of the interlinked
system. SKOV offers a wide range
of winch motors capable of operating
from 1 to 128 inlets in a house.
DA 75A Winch Motor
DA 75A is a series of very sturdy and reliable
winch motors designed especially for
controlling inlets and shutters in ventilation
systems. The design of the motors has
all functions gathered in a single cabinet.
The design and construction of the winch
motor makes it extremely easy to clean
and maintenance-free. All the variants are
relay-controlled and available for 24 V and
230 V. In case of an emergency situation,
a DOL 278 emergency opening unit can
open all swivel shutters automatically using
a 24 V variant.
DA 174 Winch Motor
The DA 174 winch motor has been designed
especially for regulating wall and
ceiling inlets in small sections. DA 174 is
available with stepless regulation for inlets
in LPV systems as well as for ON/OFF models
for controlling additional air inlets in
Combi-Diffuse houses. DA 174 is available
as a 24 V standard model and can therefore
be used in connection with emergency
opening.

Mounting sets with all the necessary parts,
including washers, wires, screws, fittings,
pulleys, etc., are supplied together with
the necessary components, subsystems
and systems. The mounting sets help
ensure quick and correct installation of the
system for optimum performance.
20

Control
SKOV Components
The climate computer controls all components
ensuring optimum functioning of
the entire ventilation system.
SKOV has wide experience in developing
user-friendly climate computers capable
of handling both simple and advanced
control tasks. All the climate computers
have modular hardware and software allowing
them to be tailored to suit individual
producer requirements.
SKOV’s climate computers control the
climate efficiently and accurately, thus
ensuring optimum growth.
DOL 234F Climate Computer
The DOL 234F series of climate computers
is used in connection with the Combi-
Diffuse, equal pressure and LPV ventilation
principles. DOL 234F controls the climate
via the PID principle so that the temperature
in the house is quickly adjusted to the
required level, ensuring the best possible
climate for the animals. DOL 234F controls
the air outlet through MultiStep® in order to
minimize power consumption. DOL 234F is
operated by means of a rotary button and a
graphical display.
DOL 339 Climate Computer
The DOL 339 series of climate computers
is used in connection with the Tunnel, LPV
and Combi-Tunnel ventilation principles.
The controller is designed primarily for
poultry production and large houses. The
temperature is controlled through the
PID principle and the air outlet through
MultiStep®. DOL 339 can be fitted with a
production module capable of handling
all basic functions in poultry production.
DOL 339 is operated by means of a rotary
button, a numeric keyboard and a graphical
display.
21

Alarm
In mechanically ventilated houses, there is
a high risk that animals will suffer serious
harm if the ventilation system fails and
is not re-established quickly. The oxygen
content of the air is reduced; air humidity
increases and the animals cannot get rid
of their excess heat. A fast and efficient
response is required. SKOV’s alarm systems
are simple, reliable, stable and extremely
efficient.
DOL 2200 Alarm System
DOL 2200 is a series of alarms triggering
alarms via a local alarm indicator – a siren,
a flashing light, etc. – or via a telephone
in case of irregularities. DOL 2200 can
monitor the temperature in 10 sections.
Alternatively, ON/OFF can be selected
for each input so that it can be used to
trigger alarms for empty silo, stuck augers,
oil burner defects, etc. Extension modules
are available if more alarm inputs are
required. DOL 2200 has a large graphical
display that shows the temperature and
alarm status for each input. If DOL 2200
is connected to a telephone line, alarms
can be transmitted to several telephones
at the same time or in a specific order.
Calls can be acknowledged thus stopping
the alarm. All functions can be controlled
remotely via a telephone.
DOL 2100 Alarm System
DOL 2100 has the same functionality as
DOL 2200 but no graphical display. An
external thermostat unit is required for
connecting temperature sensors.
DOL 2020 – combined Alarm
and Backup Thermostat
DOL 2020 is an alarm system used primarily
to monitor ventilation in houses in
combination with three backup thermostats.
Via a separate temperature sensor,
DOL 2020 is able to monitor the temperature
in a single house section and activate
extra ventilation in three steps by means
of the backup thermostats. Alternatively,
one of the steps can activate a system for
high-pressure cooling, for example.
22

Emergency Opening
SKOV Components
A failing ventilation system is the most
critical factor in a modern house; this
requires immediate action. An emergency
ventilation system ensures the well-being
of the animals as well as production.
When wall inlets, chimneys, etc. are used
for ventilation, these air inlets and outlets
can be used for emergency air intake.
When diffuse ventilation is used, an
alternative emergency air inlet is required
in the form of e.g. windows that can be
opened if the ventilation system fails.
DOL 278 Emergency Opening
– temperature-controlled
Together with SKOV’s climate computer,
DOL 278 is an independent emergency
opening system for opening the ventilation
system in case of a power or technical
failure or an operational error. The emergency
opening system is integrated in
DOL 278 and is activated when the house
temperature exceeds the temperature
set on DOL 278. The opening depends on
how much the temperature is exceeded
and is activated gradually.
DOL 278 has a separate temperature
sensor and therefore does not depend on
climate computer measurements.
DOL 278 features compensation for high
outdoor temperatures, i.e. the outdoor
temperature sensor overrides/postpones
the emergency opening function if it is
hot outside.
DOL 278 Emergency Opening
– ON/OFF
Together, SKOV’s climate computer and
DOL 278 form an emergency opening
system that opens the ventilation system
completely in case of a power or technical
failure. The emergency opening function
is integrated in the climate computer; only
the energy for opening the ventilation
system is drawn from DOL 278. In case of a
power failure, the connected air inlets and
outlets are forced open and the emergency
opening system opens completely.
23

Cooling
An efficient cooling system helps promote
animal well-being and productivity in hot
periods. It may be an advantage to use
cooling systems based on evaporation of
water for the production of both broilers
and pigs.
An outdoor temperature exceeding 30° C
in connection with broiler or pig production
may have serious consequences
for the animals in the form of impaired
growth, reduced productivity and thus
increased mortality.
SKOV offers various cooling solutions capable
of reducing the house temperature
effectively.
DA 2000 High-Pressure Cooling
SKOV offers an extremely reliable highpressure
cooling system with a long
service life. Built by standard components,
this system is flexible and easy to adapt to
a specific house.
In the high-pressure cooling system,
atomised water particles are added to the
house air. These particles evaporate in the
heated house air, thus cooling the air.
DA 2000 also features other functions
besides cooling. The high-pressure system
can be used for both humidification and
binding dust, and between the batches,
the system can be used to soak the house.
If ventilation is disconnected, the dense
water particle mist will quickly soften dirt
on various surfaces making them easier to
clean.
DA 100/150 Pad Cooling
Pad cooling is used in connection with
SKOV Combi-Tunnel and Tunnel systems.
Cooling is ensured by air taken in through
pads, which are kept constantly moist by
recirculating water. Air is sucked through
these pads and cooled by the absorption
of water vapour. SKOV offers a complete
channel system that adapts easily to the
relevant house. As opposed to other systems,
no separate water tank is required
for DA 100/150 pad cooling. The tank is
built into the lower channel and is thus
an integrated part of the channel system.
Pads are easy to mount and remove by
means of a click system: no tools are required.
SKOV uses recognised cooling pad
brands with a long service life.
24

Heating
SKOV Components
An efficient heating system helps promote
animal well-being and productivity in cold
periods. If the heat supplied to the house
is insufficient, a large part of the feed digested
will be used to maintain the body
heat of the animals.
SKOV offers inlets for heating system
control.
DA 74 Ball Valve
DA 74 J/JK is a series of two-way and
three-way control valves fitted with a
motor. The motor is available as either
an unenclosed (DA 74 J) or an enclosed
model (DA 74 JK), which are well suited for
aggressive house environments requiring
thorough cleaning. The valves have dirt
traps and return valves.
Solenoid Valve
SKOV’s solenoid valves are extremely reliable.
The solenoid valves are two-way ON/
OFF valves making them well suited for
small houses. The valves have a dirt trap
and a return valve.
25

Production Control
SKOV’s computers monitor and control
feed and water supply to the animals,
registering the weight of the animals
through continuous weighing. In addition,
the production computer keeps track of
the current number of animals, installed
animals and dead animals.
DOL 95 Broiler Production
Computer
The DOL 95 Broiler production computer
has a flexible and efficient feed control system
which is based on an advanced feed
program that also registers the quantity of
feed consumed. The production computer
registers the weight of the chickens
through a connected poultry weigher; it
also controls light and water and registers
the silo content. DOL 95 can store data for
up to six batches of broilers.
DOL 95 Breeder Production
Computer
DOL 95 Breeder is a production computer
for animals being reared as well as for parent
stock. The DOL 95 Breeder computer
not only offers the same high functionality
level and possibilities as the DOL 95 Broiler
computer, it also contains functions used
especially for animals being reared and
parent stock. The key function in this connection
is separate outlet feeding which is
used in houses where animals are divided
into groups with different feeding needs or
in the production of parent stock requiring
separate outlet feeding of hens and cocks.
DOL 96 Weighing Computer
DOL 96 is designed especially to monitor
production in houses with poultry where
DOL 96 can register the weight of the
birds. DOL 96 is available in three models
which can be connected to two, four or
eight poultry weighers, respectively. For
each poultry weigher, DOL 96 calculates
data such as average weight, growth, deviation
in relation to reference weight, etc.
DOL 65 Production Computer
DOL 65 has a flexible and efficient feed
control system. DOL 65 can be used in
connection with dry feeding systems and
monitor/control the production of finishers
from weaning up to slaughtering.

Animal Weighers
SKOV Components
SKOV’s animal weighers, which ensure accurate
measurements, are sturdy and reliable
and thus provide the producer with a
better yardstick for his production.
As the weighers are in direct contact with
the animals, they are designed to cope
with the natural, harsh house environment
and animal behaviour. Furthermore, the
weighers are not only easy to clean but
also easy to remove for cleaning purposes.
DOL 98B Poultry Weigher
The DOL 98B poultry weigher is designed
for weighing poultry up to 3kg. The
weigher is typically used in combination
with the DOL 95 production computer in
connection with broiler production. One
poultry weigher per house typically gives
between 200 and 1000 weighings per 24
hours. The average weight and variation
values are therefore very close to the
actual values in the house. The mechanical
construction of the weigher is adapted
specifically for the environment in poultry
houses.
DOL 94 Platform Weigher
DOL 94 is a platform weigher designed for
automatic weighing of poultry up to 10kg.
DOL 94 registers the weight of the birds
extremely accurately and transfers the
weighing data to a connected livestock
house computer. The bird weigher resets
after each weighing and deposit on the
platform weigher of dirt and litter is therefore
not a problem. Likewise, it can take
into account that several birds mount the
bird weigher at the same time. DOL 94 is
easy to handle, clean and calibrate.
27

Feed Weighers
Feed is an important financial cost in
animal production. Feed consumption
in relation to production is an important
parameter for evaluating farm efficiency.
It must therefore be possible for the
professional producer to carry out ongoing
analyses of production. With feed
weighers from SKOV, the producer has
every chance of finding and removing the
causes for any irregularities in production.
DOL 99 Feed Weigher
The DOL 99 feed weigher is a stand-alone
weigher. The DOL 99 feed weigher can
dose one component and DOL 99-2 two
components. DOL 99-2 can be used e.g.
for the production of broilers that are
given complete feed and wheat. DOL 99
and DOL 99-2 are equipped with control
units for controlling the weigher and
calculating and saving the values of the
weighed quantities of feed. For DOL 99-2,
the mixture ratio for the two components
is also set in this control unit.
DOL 99B Feed Weigher
The DOL 99B feed weigher works together
with SKOV’s production computers. The
DOL 99B feed weigher can dose up to
five components. All data is entered and
read out via the production computer.
The totally weighed quantity of feed as
well as the quantity at periodic, 24-hour
and batch levels can be displayed on the
production computer.
28

Air Cleaning
SKOV Components
The incentive to develop systems for
cleaning house air derives from the
agricultural sector being under great
national and international pressure to
reduce its environmental load. For animal
production, this involves requirements for
a reduction of ammonia emissions, other
nitrogen compounds, etc.
This also applies to odours from houses.
Producers are facing an increasing number
of limitations when they wish to establish
new house systems or extend them. These
limitations often occur in the form of
protests against the odour load.
Recent research results have shown that
dust from houses can be disease carriers.
SKOV has developed an efficient air-cleaning
system for cleaning the outgoing air.
Farm AirClean
Farm AirClean is a system for biological
cleaning of air. The system is based solely
on biological air-cleaning principles. These
principles are effective when it comes to
reducing odour, ammonia and dust.
Thorough Testing of the System
has shown that:
• The content of ammonia in the outgoing
air from the house is reduced to less
than 1 ppm.
• The ‘pig smell’ is removed from the
outgoing air.
• The content of dust in the outgoing air
is reduced by 95%.
Farm AirClean is a modular system where
the quantity of air cleaning cabinets can
be calculated based on the number of
cubic metres of house air to be cleaned.
The cleaning units are available in capaci-
ties ranging from 10,000 to 40,000 cubic
metres per hour. All units are fitted with
automatic filter washers.
The house air is sent through two filters
which are sprinkled with water. Ammonia
and odour substances are removed
in both filters while most of the dust is
removed in the first filter. The air cleaning
process is a biological process. Bio films
of bacteria and other microorganisms are
formed on the filters. Ammonia, odour
substances and dust are removed when
the house air gets into contact with the
water and the bio films in the filters.

Management - FarmOnline®
Access to data at the right
time and place
FarmOnline® is a management tool which
SKOV has developed for use by the still
larger pig and poultry farms. The system
ensures the producer the highest possible
yield from his production facility. Farm-
Online® is able to monitor several house
computers from a central location and
present the collected data graphically.
Fast, competent action
SKOV’s new generation of house computers
has a built-in LAN Ethernet. It is,
therefore, not necessary to collect data between
house computers and a PC thanks
to the live connection of FarmOnline® to
all house computers on the farm.
The system also makes it possible for
the producer to react immediately to an
alarm and, if required, change the house
computer setup via FarmOnline®. When an
alarm is generated, the producer can react
quickly and efficiently. Quick action may
ensure the welfare of the animals as well
as reduce or completely prevent financial
losses.
Visualisation
FarmOnline® is able to import the producer’s
own photos and drawings of the
farm and sections, ensuring high graphic
recognisability in the program.
So-called hotspots can be added to the
overview pictures to show the key values
for indoor temperatures, alarm status, etc.
Adding graphic features for all levels (farm,
house, section) will make it easy for the
producer to navigate in the program,
ensuring fast overview of conditions and
accurate localisation of deviations.
NEW
Overview
The overview function enables alternative
reading of key values and alarm and house
status for the entire farm and for individual
sections.
The producer chooses which values to be
included in the overview function.
Tables can be exported to other file formats
such as PDF, Microsoft Excel, etc. for
documentation or analysis.
Alarms
Alarms are shown by means of a pop-up
function, no matter which program is active
on the PC.
FarmOnline® displays alarms as red markings.
Simply click the marking to open an
alarm window with alarm details. Users
authorised for this may acknowledge the
alarm. Notes on alarm causes, troubleshooting,
etc. can also be added to each alarm.
The Log and Diagram functions contain
various search criteria making it possible
to analyse the occurrence of historic
alarms, thus adding to the experience of
the users. In addition to alarms from SKOV
house computers, FarmOnline® is also able
to handle alarms from external units.
To get a complete picture, alarms can also
be entered manually into the FarmOnline®
History function.
Climate
Once the producer has become familiar
with the various overview screens, the
climate screen makes it possible to go
deeper into the climate control function.
Selected key values for temperature,
humidity and ventilation are displayed
by means of easily comprehensible
graphic elements in which settings can be
changed directly. Batch curves are also accessible
for houses with all in/out production.
The efficient Climate History function
of FarmOnline® allows data storage for up
to five years. Several search criteria enable
requested data to be extracted and indicated
in the form of curves.
