Description

For cooling, heating, and fresh air supply along the facade, through window parapets; high level of thermal comfort
Primary air volume flow rate: 8 to 36 l/s [30 to 130 m3/h]
Low pressure loss (70 to 200 Pa), therefore energy-saving operation
Low sound power level
Heating also possible without primary air, which saves energy when heating at night and at weekends
Heat exchanger cleanable from the front and the rear (in compliance with requirements of VDI 6022).
The large fin spacing enables easy cleaning and obviates the need for a filter.
Suitable for new or refurbished buildings
Condensate tank below heat exchanger, inclusive of drain with ½“ connector
