Heat Retrieval Unit (WTW)

A 'heat retrieval unit' is capable of recovering energy from the (warm) exhaust air from domestic houses.

Systec Designs has revised and strongly modernized the electronics that control the WHR930 Heat Retrieval Unit of the Zehnder Group (formerly J.E. Stork Air).

The modernized electronics calculate the optimal incoming and outgoing airflow based on continuous measurements and user presets.

The revised electronics of the unit can be driven by remote control using radio technology, or by a wired connection.

Together with a considerable improvement in functionality, a significant reduction in production costs has been achieved.
