HRV (VKM) introduces fresh outdoor air with
minimum heat losses, while a wide variety of features
respond to customer requirements.
Efficient outdoor air introduction is possible
Humidifier
DX-coil
High static pressure
The lineup includes models with a humidifier,
in response to diversifying customer
requirements. (VKM50/80/100GAMV1 only)
The HRV features DX-coil that contributes to
the prevention of cold airflow hitting people
directly during heating operation, due to the
after-cool, after-heat operations done
beforehand.
Higher external static pressure means
enhanced design flexibility.
