Equipment list
The device consists of 2 housing parts
Part 1 (basic module)
equipped with supply air fan, exhaust air fan, mixed air chamber, PWW heating register, supply air filter, and control cabinet equipped with a control unit.
Part 2 (WRG module)
with heat exchanger for energy recovery, condensate collecting tray, droplet separator, exhaust air filter
Housing
Stable, corrosion-resistant profile frame construction made of aluminium hollow chamber profiles, powder-coated. The profiles are thermally decoupled by means of integrated plastic webs, so that the heat transfer between the device chambers and the environment can be reduced to a minimum level. Cladding panels equipped with highly insulating Hydrotec foam core. Circumferential base.
Supply/extract air fan
equipped with energy-saving, stepless EC direct current motors.
Mixing chamber
as an outside air/circulating air mixing chamber with two louvre flaps opening in opposite directions.
Air heater
Pull-out heat exchanger for hot water operation.
Supply air/extract air filter
Slide-in frame equipped with a Z line filter. Filter cell with pleated filter medium, fully incinerable and metal-free.
Energy recovery
Pull-out plate heat exchanger based on the counter current principle for the heat recovery of the sensible and latent heat energy contained in the air flows.
High temperature efficiency (up to 95%)
Coated stainless steel condensate pan equipped with a side drainage connector.
Control cabinet and control unit
integrated in the device with all modules for all tasks in the fields of control and monitoring.
Control package equipped with a touch panel control UNICON C, a colour display of 4.3 inch, and integrated in the control console.
Various interfaces (Ethernet TCP/IP, CAN, OPC, RS484, RS232) enable the connection to building management as well as third-party systems. Thanks to the optionally integrated web server, the operation or data transfer can take place through the internet as well. Various software options.
