OPERATION & MAINTENANCE Air handling unit RT 400S-EC
REC-E08.10
General/Introduction
REC Indovent has been manufacturing Temovex air
handling units since the 1970s.
User-friendliness has been the order of the day right from
the outset. For us, one of the most important things is
to make sure our users feel secure and can handle the
minimum of maintenance with no fuss. And of course, the
fact that you also demand market-leading performance
as regards energy consumption and recovery is also a
natural consideration in our ongoing development work.
Our amassed experience has all been combined to
create your Temovex unit.
Temovex units are a quality product made in Sweden,
with a long service life and extreme reliability with no
unpleasant surprises.
And just to prove that our efforts are taking us in the
right direction, Temovex units have won first prize in
the Swedish Energy Agency’s technology development
competition, looking for the best ventilation heat
exchanger. The motto for the competition was as follows:
“To save energy and the environment with inexpensive,
efficient, reliable ventilation heat exchangers”.
To ensure your entire ventilation system maintains its
performance throughout its entire design service life, you
should follow the simple maintenance instructions in this
booklet.
This unit is designed for continuous operation. It should
only be shut down for servicing or inspection.
The unit must never be operated with no
filters fitted.
System descriptions
Operation principle
The Temovex unit
The Temovex unit
consists of fans, air filters,
afterheaters and a highly
efficient counterflow heat ex-
changer developed by our-
selves. The counterflow heat
exchanger is very well sealed,
which prevents odours, con-
taminants, etc. from coming
back into the home.
A long service life, low
operating costs and a low
maintenance requirement are
ensured thanks to the use of
top quality, reliable compo-
nents and design solutions
involving few moving parts. The thermal energy in the
air sucked out of the building is transferred in the heat
exchanger to the fresh air coming into the building. The
Temovex unit retains the heat or coolness in the building
without supplying new thermal energy. (Compare this
with a thermos.) Making the most of the thermal energy
already present in the building allows the operating
time and/or size of the conventional heating system to
be reduced. Comfort is also enhanced because the air
entering the home is at a temperature nearer to room
temperature than it would have been if the air had been
taken in directly from outdoors. At the same time, the
indoor environment is really enhanced because all the
air entering the building passes through a fresh air filter
(outdoor air filter). One filter also makes maintenance
easy. With Temovex it’s easy to access!
