COMBINED VENTILATION
Save energy costs by using this especially
effective ventilation system.
It is economic and reliable while in operation and
insures a livestock-friendly and efficient climate inside
the stable at any time of the year.

COMBINED VENTILATION
Four seasons – simply the best temperature!
RIMU combined ventilation approves all pledges concerning efficiency
by a long-term-study carried out by the University of Bonn, Germany:
Top: Combined air duct in the attic.
Thereunder on the left side: incoming air ventilator
for combined operation.
On the right side: automatic supply air flap at
the ceiling (summer).
Thereunder on the left side: an example in a
fattening unit.
On the right side: operation in a fattening unit
with 750 animal spaces.
· Very good adjustability of the system
· Low failure ratio and high vitality of all animals
· Low carbon dioxide
and ammonia values
· Lower energy consumption
than other systems
“The advantages stated
by RIMU have been approved
by different measurings”

The way to a profitable stable climate
In order to guarantee a livestockfriendly
and thus, a profitable stable
climate during the whole year, technical
effort is required. So, ventilation
ducts and temperature stability (heating!)
in connection with sophisticated
control technology and electronic are
most important.
When using the original RIMU-combined
ventilation, the temperatures
are correct at any time of the year!
This system is cost-effective in operation
and despite extreme operational
requirements between summer and
winter it is absolutely reliable. It is the
ventilation system “Four Seasons”.
Consistent air distribution
The combined ventilation comes as a
pleasant surprise since the incoming
air flow is distributed inside the
whole stable by the radial ventilator.
Thereby, it can be guaranteed that all
farm animals are supplied with fresh
air and contaminated air flows are
completely reduced.
These positive effects are even more
supported by deep exhaustion and
precisely regulated control technology.
Handling difficult weather conditions
When the external air is getting
colder, it is possible to work proportionately
with combined ventilation.
With the help of a blend door, this
happens automatically. The fresh air
ventilator operates actively and at the
same time it distributes the fresh air
at relatively low air rates by absorbing
the air from a specially assigned
incoming air duct. This controlled
preheating without charge and the
optimal distribution of the air mixture
via radial ventilators is the actual secret
of this system. So there is no temperature
drop due to cooler outdoor
air and no harmful gas. Heating
costs decrease distinctly and this
leads to energy savings up to 50%!
Cost saving in relation to heating and
electricity
In need of higher or high air rates,
the energy supply to the radial ventilator
is closed and then it operates
passively but still distributes the air so
that costs can be saved in electricity.
In this case additional air flaps open
due to negative pressure and so, air
exchange can be guaranteed. The
blast ventilating effect provides for a
pleasant stable climate in summer, so
that the vitality of the farm animals is
growing.
Hereby, completely new point of
views open up in relation to animalfriendly
livestock-breeding conditions
in connection with operating liability
and cost reduction. RIMU-combined
ventilation can be retrofitted easily
and economically by using few preassembled
components.
The original RIMU-combined-system
is a fully developed ventilation system.
It does not have to avoid comparisons
to other solutions on this
sector. All known advantages were
proven again by a long-term study
executed by the University of Bonn in
2008.wieder bestätigt:
1. Little failure ratio
2. High vitality of farm animals
3. Low emission concentration of
CO² and NH³
4. Low energy consumption.

Operators are pleased!
Experts say that air circulation systems
use up a lot of electricity due to
the extensive air circulation. However,
this argument could be refuted
by performing a rating under real
conditions: In a pig fattening unit
with 600 animal spaces in the east
of the German federal state of Brandenburg
data were collected on a
weekly basis, which lead to positive
results. Operators and stable staff are
very content with the ventilating per-
formance and they say that the handling
of the climate computer is easy
and intuitional. The animals gained
weight at an average of 400 g per
day (animals with a weight of 5 kg
up to 27 kg), which was good and
the share of CO² emissions at minimal
ventilation was considerably
below the critical value of 3,000
ppm (according to the regulations for
pig breeding).
