VEX4000 - CROSSFLOW HEAT EXCHANGER

The classic crossflow heat exchanger secures stable, economic operation and meets the requirement for separated air streams, so that neither contaminated air nor humidity are transferred from extract air to supply air.

A crossflow heat exchanger can achieve a temperature efficiency of up to 73 %, which can be an advantage in buildings with too high a heating surplus.

By-pass

For regulating the heat exchanger's performance, there are integral by-pass ducts which allow the outdoor air to be wholly or partly diverted round the heat exchanger. This can be utilised in the shoulder seasons, where there is no need for full heat recovery.

Condensation outlet

The crossflow heat exchanger module is fitted with corrosion-proof base trays, with a fall to the drain, allowing cleaning of the heat exchanger while mounted in the unit. The condensation drains have smooth piping and exit the panel on the operating side, where a water trap should be fitted.
