VKM-GB/VKM-GBM

Energy recovery ventilation,

humidification

and air processing

Post heating or cooling of fresh air for lower
load on the air conditioning system

› Energy saving ventilation using indoor heating,
cooling and moisture recovery
› Creates a high quality indoor environment by pre conditioning VKM80-100GB(M)
of incoming fresh air
› Humidification of the fresh air results in comfortable
indoor humidity level, even during heating
› Free cooling possible when outdoor temperature is below
indoor temperature (eg. during nighttime)
› Low energy consumption thanks to DC fan motor
› Prevent energy losses from over-ventilation while improving
indoor air quality with optional CO sensor
2
› Shorter installation time thanks to easy adjustment
of nominal air flow rate, so less need for dampers compared
with traditional installation
› Specially developed heat exchange element
with High Efficiency Paper (HEP)
› Can operate in over- and under pressure
