VEX4000 - CROSSFLOW HEAT EXCHANGER
Modul
- Standard crossflow heat exchanger in aluminium - for extraction and other purposes with no special requirement for high efficiency
- High aluminium crossflow heat exchanger - for higher efficiency
- Crossflow heat exchanger in high aluminium ERP18 - for extra high efficiency
- Epoxy-coated crossflow heat exchanger for particularly corrosive environments

Product advantages
- Fully separated airflows to prevent the transfer of stale air or moisture between airflows
- Built-in bypass that allows outdoor air to be diverted completely or partially around the heat exchanger if heat recovery is not required.
- Choice of 4 different heat exchanger types (Standard, High aluminium, High aluminium ERP18 and Epoxy for corrosive environment.)
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.
