One range 

- Lots of possibilities 

EXstream performance: 

The entire VEX100 range is supplied with EXHAUSTO’s newly 

developed centrifugal impeller, which with its high efficiency 

and low sound levels is one of the best on the market. Along 

with the EFF1 class motors, this gives a high performance with 

low SFP figures. 

Efficient vibration suppression: 

The fans are suspended on a track system, 

which makes pulling out and servicing easy. 

The design of the suspension system, with 

the motor, impeller and intake together 

suppresses vibrations very effectively. 

Solid construction: 

The VEX100 cabinet is made of 

aluminium-zinc AZ185 C4 and insulated 

with 50 mm mineral wool. The VEX 100 

can be delivered for fitting outdoors. 

Flexible unit design: 

The VEX100 unit can be supplied with the air supply on either 

the left-hand or right-hand side. Spigots can be placed on the 

sides and the top/bottom as required. 

The VEX140, VEX150 and VEX160 are supplied with round 

spigots. The VEX170 is supplied with rectangular duct 

connections, with a Lindab Safe or METU flange system. 

All of this gives increased flexibility and innumerable options.

Airflow from 400 to 8,400 m 3 /h 

with the VEX100 range 

Integrated control: 

The control system is integrated in the VEX100 just above 

the cross-flow heat exchanger. The control system is 

grouped together on a pull-out plate for ease of service 

access. All connections are at the front in the integrated 

connection box, so that no space is used above the unit. 

The cables are at the side of the connection box. The 

measurement socket is located in the box. 

Base: 

The VEX140, VEX150 and VEX160 are supplied as standard 

with feet. It is also possible to order a base as extra. 

The VEX170 is supplied with an integrated base with 

adjustable feet. 

3 

Efficient cross-flow heat exchanger: 

The cross-flow heat exchanger is made of aluminium with low 

pressure loss and a high temperature efficiency. The 

cross-flow heat exchanger ensures complete separation 

between the air passages, so no smells or impurities are 

transfered to the supply air. 

Compact filters: 

Built-in condensation tray: 

The VEX100 range is fitted with a stainless 

steel condensation tray. 

RD11368-01 

The VEX100 range is supplied with compact 

(panel) filters. 

As standard F5 filters are supplied. 

F7 filters are available as extras. 

Heating coil, water or electric: 

VEX100 units are supplied with integrated post-heating 

coils, either for water or electricity.

VEX100 Control system - Regulation 

The VEX100 control system meets all the control requirements 

for maintaining a perfect indoor climate. As standard there 

is an option to control the VEX100 from the DDC unit via 

LONWORKS ® or EXHAUSTO’s iTool Internet server, which gives a 

direct connection to the VEX from your PC. 

Several operating levels - save energy 

The control system features a range of options designed to 

save energy when operating in economy and standby modes 

(see fig. 1). 

Regulation principles 

The control system controls the built-in heating coil (water or 

electric) in sequence with a bypass and an EXHAUSTO cooling 

unit, if used, (fig. 2). 

The control offers options for regulating the room 

temperature or the supply air.

Comfort Standby Economy 

The control system regulates the damper (heat recovery effect) 

to maintain the required T-comfort of 22 °C. With T-comfort, 

it is set to how close to the 22°C temperature is required, either 

heating (22-1 = 21 °C) or cooling (22+1 = 23 °C). 

Standby operation with low airflow (step1) gives the option to 

achieve even greater savings by setting to T-standby. 

As shown above, this is achieved with heating 22-3=19 °C, and 

with cooling 22+3 = 25 °C when the unit is in standby. 

With economy heating the setting is an absolute temperature, 

such as 16 °C for heating and 30 °C for cooling. This allows the 

option to lower the temperature during heating and that the 

cooling unit only starts when the temperature rises above 30 °C. 

With the control of the cooling unit there is also an option to 

set the max. temperature difference T between the room 

and supply air temperature. 

36 

Room temperature control 

Room temperature is controlled by means of the built-in 

temperature sensor or an external room sensor. 

When regulating the room temperature there is also an option 

for summer compensation (fig. 3). 

When summer compensation is selected, the set point for the 

desired room temperature will increase in line with the outside 

temperature. This avoids an unpleasant cold shock because 

of too great a difference between the indoor and outdoor 

temperature, and also saves energy. 

Supply air regulation 

When regulating the supply air temperature there is an option 

for outdoor compensation (fig 4). When this is selected the set 

point for the supply air temperature is lowered in summer (and 

possibly raised in winter) and so the supply air temperature is 

compensated on the basis of the outdoor temperature. 

The temperature is compensated by the built-in temperature 

sensor in the outside outdoor air spigot. 

Fig. 2: Heat, bypass and cooling control

VEX100 control system - advanced standard functions 

Fig. 3: Regulation of room temperature

Required room temperature = 20 °C 

Additional standard functions 

Night-time cooling 

Without any extra equipment, night-time cooling can be selected, 

which functions without any cooling unit being attached. 

In buildings with large mass (weight) the comfort in summer 

can be improved by cooling the building with cool outdoor air 

at night. 

Night-time cooling is particularly suitable for offices, 

institutions, etc. where people do not work at night. 

Night-time cooling can only be activated during the summer 

and when the unit is not in comfort operating mode. It is 

possible to set a temperature and a time for night-time cooling. 

Frost protection of water heating coils 

Frost protection of water heating coils is controlled by 

temperature sensors on the return pipe. If during operation the 

temperature falls under the set temperature, the unit stops. 

When the unit stops a heat retention function starts which 

keeps the water in the return pipe at a set temperature. This 

minimises the risk of frost in the heating coil and the unit 

is ready to start immediately even when the temperatures 

outside are low. 

There is also an built-in control to run the circulation pump 

during periods when heating is not required. 

Starting the unit 

On starting the unit always runs for a few minutes with 

extraction to warm up the cross-flow heat exchanger before 

the supply air is started. 

37 

Fig. 4: Control of supply air tem perature 

with outdoor air compensation 

Required supply air temperature = 20 °C 

Max. supply air temperature = 35 °C 

Min. supply air temperature = 10 °C 

Run on with electric heating coil 

With an electric heating coil there is a built-in run on, so the 

fan runs for three minutes after the unit stops. During these 3 

min. the heating coil is disconnected. 

Outside compensation of airflow 

The control system has a built-in function for reducing 

the airflow when the outdoor temperature is falling. The 

temperature is measured in the outdoor air spigot. 

Filter control 

There are built-in filter controls in the unit. These are located in the 

connection box and can easily be set during operation. If a filter 

needs to be changed a yellow lamp lights up on the DISPLAY and 

TOUCH-panel and an entry is made in the alarm list. 

De-icing function 

The de-icing function is activated on the basis of a set 

temperature measured at the exhaust spigot. 

When the function is activated, the supply airflow is reduced 

to 1 step, or bypass de-icing takes place. 

Bypass de-icing is carried out through the following 

procedure: 

• The control system registers icing on the cross-flow heat 

exchanger 

• The bypass damper opens slowly (10% per minute). The 

normal temperature control system will deal with opening 

the motor valve and supplying post-heat. 



VEX100 Control system - options 

In addition to the numerous standard functions there are also 

options, such as: 

• Airflow control to maintain the airflow rate even if the filters 

are dirty etc. The airflow is shown in the DISPLAY panel. 

• Airflow control is a requirement with a cooling unit in order 

to monitor the minimum airflow 

• Detecting ice in the cross-flow heat exchanger on the basis 

of pressure measurement (requires airflow control) 

The functions listed above can be fitted to the VEX unit to order. 

Example of control of airflow with CO 2 and/or humidity override 

When the automatic control system is 

operative, this function can be used to 

increase the required airflow when the CO 2/ 

humidity concentration in the room increases 

Example of ZONE control with modulating damper and constant pressure regulation 

• Constant pressure regulation of the flow 

of extract and/or supply air 

• CO2 sensor for overriding the fan speed 

• Humidity sensor (RH) for overriding the 

fan speed 

• ZONE control of local on/off damper 

via, for example, manual activation, 

PIR sensor (Passive Infrared Receiver or 

hygrostat on/off) 

• ZONE control of local modulating 

damper (0-10V control voltage) via, for 

example CO 2 or humidity sensor

- Connection to external units 

Connection to external units 

External units operate via the EXHAUSTO Operating Network 

(EON), which is a bus-based network. 

With the start and initial adjustment of the unit the control 

system checks what units are linked to the network. During 

day-to-day operation, the control system monitors all the units 

that are operating and provides information about any errors 

that may occur. 

The units to be linked to the network should be positioned in 

a structured manner, like a daisy chain. 

The signal cable is a 4-wire cable (2x2x0.6mm) where 2 wires 

are used for the electric current (24VDC) and 2 are used for 

communication. 

Service can be carried out quickly without affecting the other 

units in the network, as one module can be removed without 

breaking the connection to the others (the cable is looped 

onto plug terminals). 

For servicing, an extra DISPLAY panel can be linked to the VEX. This 

has to be done in specialist mode and overrides the normal 

operation of the unit. 

Connection to DDC unit 

VEX100 Control system can be connected to LONWORKS ®, 

which is an open communication system with standardised 

communication exchange. 

LONWORKS ® is integrated in the control system, and LON- 

Mark compatibility is assured in the relevant areas. A standard 

network variable is used (SNVT) to transfer all the information 

allowing a connection to most DDC units and other control 

systems.The control system has a built-in communication 

interface to LON-network with a transceiver (FTT-10A). 

The transceiver functions as a transmitter/receiver between the 

control (neuron chip) and the LONWORKS ® network 

The VEX100 control system can power LONWORKS ®units with a 

max of 250 mA. 

EXHAUSTO has tested LONcommunication in partnership with 

the leading DDC suppliers in Denmark. 

iTool – connection to the ventilation unit via your PC or mobile 

iTool is an Internet server, which connects the ventilation system 

and the Internet using TCP/IP protocol. This allows you to 

monitor and control the ventilation system from your computer 

or from your mobile phone – via the Internet or a local network. 

Just link up your computer to iTool. The communication from 

your computer will take place over an ordinary Internetbrowser 

such as MS EXPLORER 5.5 or higher. Then use Adobe 

Reader 6.0. iTool’s software has been developed for MS 

EXPLORER, but can work with NETSCAPE. 

This means that communication can take place whatever 

set-up you have.

VEX100 for other control systems 

Freedom to choose 

As alternatives all VEX100 units (except VEX170-1) offer a 

solution with a different control system. This allows integrating 

the VEX100 units with a control system from other suppliers. The 

solution is optimised for simple and efficient integration on site. 

The following table shows which components are included in a 

VEX100 for another control. 

The connections are all made at the same place 

To make the fitting and integration as simple as possible, all 

the connections are collected on a terminal board. The motor 

cables, connections to the electric heating coil, hoses for flow 

volume measurement and pressure loss are led to the terminal 

board. The bypass-motors are tested and fitted, and the 

connections led to the terminal board. 

The water heating coil is fitted and the connections are led out 

through the cabinet. 

Capacity 

The solution for another control system is supplied with 

the same highly efficient motor as the VEX100 units with 

integrated control, although without a frequency converter.

Conditions for capacity data 

EXHAUSTO air handling units 

are measured with a 1m level 

duct (VEX170 however with 

2m) for all connection ducts. 

The uniform low speed profile 

of the air in the spigot does 

not cause significant system 

pressure loss. This means that 

bends can be used immediately 

after the unit. 

p t is the total available 

pressure on both the extract 

and supply air sides. 

All internal pressure loss in 

the cross-flow heat ex changer, 

the post-heating coil and 

clean filters (F5) is deducted. 

Conditions for sound data 

EXHAUSTO air handling units 

must be fitted with silencers 

in the duct system in 

ac cord ance with the applicable 

sound regulations for 

both the premises to be 

ventilated and the 

surrounding area. 

In order to meet the 

ap plic able norms, the duct 

system must be insulated out 

of consideration for sound, 

heat loss and condensation. 

Sound output levels are used 

as the basis for calculating 

the sound pressure level in 

the operational area of the 

unit, and the level of silencing 

required in the duct system 

itself.

Valve 


Max. differential pressure 200 kPa 

Permissible medium temperature 5... 110 °C 

Calculation of k vs value 

Start by calculating the heating requirement P[kW], which is 

used to calculate the volume of water, q w . 

This value is used in the formula for pressure loss control, 

p MVM . 

The kvsvalue is then found in the diagram below on the basis 

of the calculated water flow qw (The kvsvalue must be in the interval 5...20 kPa). 

Calculation of heating requirement 

The heating requirement is determined with the following formula 

P[kW] = (t-t e ) (0.34 x q v m3/h) 

1000 

t e (air temperature before heating coil) at: 

t out = -12 °C means that t e = 8.4 °C 

t out = -30 °C means that t e = 1.2 °C 

(η t = 60 %, t extract = 22 °C) 

The temperature, t, must be greater than or equal to the 

desired supply air temperature + the temperature drop in the 

duct work system, if any.

VEX100 for outdoor fitting 

The VEX100 cabinet is insulated with 50mm mineral wool, and so 

is suitable for outdoor fitting. 

For outdoor fitting the VEX is supplied with a complete roof with 

service hatch which ensures easy access to the control system. 

The roof is designed so that cables can be led under it to both 

sides and to the back of the cabinet. 

The motor valves and damper can also be supplied in a model for 

outdoor fitting.

Carbon filter 

The idea behind the installation of a ventilation unit is to 

provide buildings with outdoor air and thereby contribute to 

improved well-being and comfort. 

The EXHAUSTO carbon filter solution consists of a housing 

insulated with 50 mm insulation material of the same execution 

as the VEX unit with carbon filter of compact execution 

adapted to the individual units. 

Using EXHAUSTO carbon filter effectively removes offensive 

odours (not pollutants) as the filter material absorbs organic 

vapours/gases and smells, as well as sulphur dioxide, which is 

often prevalent in city environments.

VEX100 Service and maintenance 

Operational reliability requires regular maintenance 

EXHAUSTO products are reliable and solid solutions. But even 

the best solutions require continuous maintenance and service 

to ensure problem free operation. 

The fan sections are suspended in track 

systems which make pulling them out and 

servicing them easy. The motor, impeller and 

inlet are collected together in the track 

system. This gives extra effective vibration 

suppression. 

The cross-flow heat exchanger can easily 

be removed from the unit for cleaning, 

although the connection to the bypass 

motor must be disconnected (remove 

the plug). 

51 

The life of EXHAUSTO carbon filters depends to a great extent 

on the strain placed on the filter – but there is an expected 

lifetime of approx. 2-3 years. Whether the filter actually needs 

to be replaced depends entirely on the user’s perception of the 

air quality. 

The EXHAUSTO carbon filter is especially intented for use in 

the field of residential ventilation where rotary heat exchangers 

are applied. The carbon filter may also be used with other 

types of ventilation plants where the outdoor air contains 

undesirable gases/smells to be removed. 

To gain optimum benefit from the filter, the inlet side must be 

protected by a pre-filter having a minimum filter class of F7 

and should, if possible, be placed before the cooling unit and 

after the heating coils. 

We have made the VEX100 range as easy as possible to service 

continuously. Replacing the filters protects against dirt on the 

cross-flow exchanger and the impeller and prolongs the 

lifetime of the unit. 

The compact filter can very easily be 

changed by pulling out the filter 

cartridge and putting in the new filter.
