Fans
For both the supply and exhaust air, high-performance EC fans are used (direct drive wheel in semispiral housing with
fitted spring-mounted electric motor). Due to the fans; the units are highly efficient with very low specific power input.
Hea t r eco v e r y co r e
The units are equipped with a newly designed high-performance heat recovery core. This is made of thin plastic plates
with high recovery efficiency up to 93 %.
By - pass dampe r ( „B“ )
The heat recovery core bypass, includes an actuator. When opening the by-pass damper, airflow through the
recovery core closes automatically to avoid heat transfer.
