Product description 

 

Temovex Blue 4 is an air handling unit (AHU) fitted 
in a cabinet.  The unit is designed for the ventilation 
of homes, offices, nurseries and other small 
premises. 
The Temovex unit should be installed in a heated 
room, such as a scullery, laundry or similar. 
 
The standard Temovex unit consists of a 
counterflow heat exchanger, 2 fans, 2 filters, after-
heater, by-pass damper and a control system.

1. Casing 

Inside is the unit made of EPP (Expanded 
PolyPropylene). The outside casing is made of 
galvanised sheet metal with 30mm insulation. As a 
standard, the side panels and the front are white 
(powder paint). The front door has a magnetic strip 
which keeps the door closed. The unit top has 
sleeve connections made of EPP, where all ducts 
are connected. 

 
 

2. Exhaust air filter 

G4, bag (art. No. G10125) 
 

 
3. By-pass damper 

The Temovex AHU has an automatic by-pass 
damper which makes the air by-pass the heat 
exchanger whenever heat recovery is not 
necessary.  The by-pass setting is adjusted on the 
control panel. 

 
 

4. Exhaust air fan 

The unit has low-energy fan of EC type with 
integrated overheating. 

 
 
5. Supply air fan 

The same type as exhaust air fan (see point 4). 
 
 

6. Heat exchanger 

The heat exchanger is a standard highly efficient 
counterflow heat exchanger from Recair. The heat 
exchanger is made of very thinny, pleated plastic 
sheets and and the supply air and exhaust air sides 
are completely sealed from each other. This is 
important in order to avoid odours and other 
contaminants from old air seeping through to fresh 
air. The heat exchanger has no moving parts, which 
eliminates wear. 
 

 

7. Supply air filter 

F7, bag (art. No. G10126) 

 
 

8. Elevator device 

The elevator device must unfasten to make it 
possible to take out the heat exchanger for cleaning. 
(See chapter "Maintenance & service"). 
 

 

9. Adjustable feet 

The cabinet has adjustable rubber feet.

 

 
 
10. Condensate drain 

The Temovex unit is fitted with a condensate drain 
at the bottom of the unit.  This should be connected 
to a drain or fed to a floor drain.

 

 
 

11. Control panel 

All settings for fan speed, after-heating, by-pass etc

.  

are made via the control panel and the AHU's 
integrated control system. 
If you have added optional parts to your Temovex 
AHU, these functions, too, are set via the control 
panel. 

 
 
12. After-heater 

Temovex Blue 4 is fitted with an electric after-
heater, 0.9 kW.   
As an optional extra, a reinforced electric after-
heater, 1,8 kW, or a water coil (two different sizes) 
for waterborne heating is offered.  The heater is 
integrated in the unit and settings are made via the 
control panel. 
In the case of a water coil, the water connections 
are at the top of the unit, dimension DN12

The Temovex Blue 4 with water coil includes a two-
way valve and valve motor in the consignment from 
REC.
