Air Treatment Equipment Lineup
The Heat Reclaim Ventilator lineup
features the DX-coil in response to
recently diversifying outdoor air
introduction requirements.
The Heat Reclaim Ventilator (VKM series) series
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 Heat Reclaim Ventilator 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.
High external static pressure means
enhanced design flexibility.
