CADS-HE BP models
Incorporating a motorised by-pass.
The by-pass enables part of the air extracted not to pass through the heat exchanger, when it is desired to cool the premises (with a lower outside temperature than the inside).
The by-pass is reversible, so it can adapt to different airflow layouts, supplying added or extracted air according to the configuration of the ducting system.
