Plug and play heat-recovery unit

Increasingly high demands are being placed on the air quality in buildings. Multiple ventilation is often needed in order to comply with these demands. A great deal of energy is lost when standard ventilation equipment is used. To counter the loss of energy, Mark has included a heat recovery unit, the AIRSTREAM, in its product range.
The unit has an efficiency upto 90%. This means that 90% of the energy expelled is supplied to the fresh intake air. This high-efficiency means that in many cases no after-heating is required.

The AIRSTREAM heat recovery unit is available in two versions for both indoor and outdoor installation. The AIRSTREAM CFX is equipped with a certified high-efficiency counterflow heat exchanger with bypass. The AIRSTREAM HWX is equipped with a corrosion-resistant rotary heat exchanger.

Possible applications for the AIRSTREAM include: offices, schools, workshops and changing areas.

The Mark AIRSTREAM fully meets the current requirements for the ErP-regulation 1253/208 for ventilation products. Would you like to know more? Download our informative flyer.
