Application example

Ventilation solution for a 3-room flat with PPB 30 K ventilation units for the bathroom and PP 45 ventilation units for living spaces

The PPB 30 in the bathroom ventilates and extracts air from the room, at the same time, in balanced mode. A fan in the unit extracts air and first transfers the exhaust air heat to the heat storage tank. Another fan in the unit pumps the supply air into the room across the heat storage tank, which gives off this heat. Every 60 seconds, the air direction changes, thereby permitting a ventilation mode with constant heat recovery.

Intensive ventilation can be activated via a humidity sensor or manually with a button if the humidity is high and/or if the air quality is inadequate.

Pure exhaust air mode is also possible and here the two fans pump out humidity (no heat recovery).

Combined with PP 45 single-room ventilation units for supply air rooms, a decentralised ventilation system for flats can also be produced for redevelopment projects.

The PP 45 units ensure an increased supply of air and therefore balanced ventilation, even if exhaust air mode is sometimes used.
