 Single Room Heat Recovery Unit - 100mm

The E-Extra Single Room Heat Recovery Unit is designed for constant air exchange in a room. The device is equipped with a regenerator that accumulates the thermal energy of the air leaving the room and heats the fresh air entering the room, thus ensuring minimal heat loss. The device is designed for continuous operation.

Principle of operation. The device works autonomously, 24 hours a day, 365 days a year, without human intervention. The process consists of two stages, 70 seconds each: 

The first stage – the fan works on extraction, removing the exhaust air from the room to the outdoors. In this process, warm air from the room passes through a heat exchanger – a ceramic mesh element and heats it up. 

The second stage – after the specified time has elapsed, the fan automatically switches to the fresh air supply. And here the previously mentioned ceramic mesh element plays the main role. Fresh air from the outside, passing through a preheated heat exchanger, gives off heat to the air which is supplied to the room already warmed up. In this way, the device provides the required air exchange for a comfortable living condition, without sharp fluctuations in temperature.
