TopVent® TW
Design, installation and operation
3 Construction and operation
The TopVent® TW serves as an air curtain to protect entrance areas against the
cold. The unit is installed over or next to the door. It takes in room air, heats it by
means of the heating coil and blows it back into the room at a high speed. This
creates a barrier of owing air, which protects the indoor climate from external
inuences.
There are 3 unit sizes, which are each equipped with an innitely variable fan and
a custom-made heating coil.
3.1 Unit construction
The TopVent® TW consists of the following components:
■ Heat exchanger consisting of copper tubes and aluminium ns
■ Tangential fan with energy-saving EC motor and ow-optimised rotor, innitely
variable, maintenance-free and quiet with a high degree of eciency
■ Compact casing made of galvanised sheet steel
■ Suspension set for vertical or horizontal installation of the unit
■ Outlet nozzle
