DESIGN &TECHNICAL INFORMATION
Air Handling Unit RT 250/400S-EC-RS
Product description
RT 250/400S-EC-RS 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.

(Nos. 2, 3, 4, 5 and 7 above, are behind cover plates)
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 white
(powder paint). 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
G3, bag (art. No. Q120101)
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 low-energy fan is of EC type. It has a wide
working range and works at constant flow ("cruise
control"), which compensates for filter clogging. The
fan motor comes with integrated overheating
protection which cuts the power and stops the fan.
Reset: turn the fan motor off for approx. 1 min.
5. Supply air fan
The same type as exhaust air fan (see point 4)
6. Heat exchanger
The highly efficient Temovex counterflow heat
exchanger was first designed over 30 years ago by
our own people, and has since been developed to fit
today's needs.
It is made of thin aluminium sheets, 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. 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, ¾". 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
RT 250/400S-EC-RS 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 RT 250/400S-EC-RS with water coil includes a
two-way valve and valve motor in the consignment
from REC..
