1. Casing
The casing is made of hot galvanised sheet metal
with 30 mm insulation between the sheets. As a
standard, the side panels and the front are powder
coated in white. The front door has a magnetic strip
which keeps the door closed. The unit top has
sleeve connections where all ducts are connected.
2. Exhaust air filter
Coarse 60%, bag (art. No. Q120101)
3. Bypass damper
The Temovex AHU has an automatic bypass
damper which makes the air bypass the heat
exchanger whenever heat recovery is not
necessary. The bypass 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
Temovex counterflow heat exchanger is designed
by our own staff and is the result of 30 years
experience of high efficient counterflow heat
exchangers.
The heat exchanger is made of thin aluminium
sheets, and is completely sealed beetween the
supply air and exhaust air. This is important in
order to avoid odours and other contaminants to
seeping through to the fresh air side. The heat
exchanger has no moving parts, which eliminates
wear.
7. Supply air filter
ePM1-50%, bag (art. No. Q120100).
8. Inspection door
When cleaning the heat exchager or controlling the
condensate drain, the Inspection door is opened.
(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, reheating, bypass 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. Reheater
RT 250/400S-EC-RS is fitted with an electric
reheater, 0.9 kW.
As an optional extra, a reinforced electric reheater,
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.
RT 250/400S-EC-RS with water coil includes a two-
way valve and valve motor in the delivery from REC.
