Decentralized heat recovery systems

Decentralized

— units that do not use internal air ducts — in other words, the supply air comes out directly from the nozzle on the unit body, and another nozzle is responsible for the exhaust in the same place (usually, a decentralized model works in both directions, see "Ventilation" for more details). Most often, such models are installed directly into a hole in the wall (see "Installation — wall-mounted"), they have low power and productivity and are intended for relatively small premises — private houses, apartments, individual offices or offices, etc.
