Save energy during ventilation with the new Marley Fresh Air Heat Recovery Unit.
The new Marley Fresh Air Heat Recovery Unit ensures regulated ventilation and helps to save heating energy – thanks to an innovative ceramic element and a ventilator with bi-directional operation. The maintenance-free ventilator is whisper-quiet and amazingly energy efficient. The unit switches from stale air to fresh air every 70 seconds. During this process, up to 85 percent of the heat from the stale waste air transported from the room is stored in the ceramic element. When the unit changes the direction of flow, this warmth is released back into the cold fresh air flowing into the room. In dialogue operation, both units communicate with each other via radio contact, three performance settings can be selected by remote control.
