The Airkel® concept requires either a simple or double flow ventilation system (that recovers heat), depending on the environment, configuration and how busy the room is.
A monoblock ensures clean air
comes in from outside and dirty air
is extracted outside.
The dual flow retains heat from the outgoing air
and uses it to warm the incoming air.
The clean and dirty air pass through a heat interchange system so that the heat is retained, warming the pulsated air to a comfortable temperature.
