Equipment list
Fan, heat pump unit for energy recovery (equipped with compressor, evaporator, condenser, filter dryer, safety refrigerant R407C), condensate collecting tray, heating register, air filter, and switching unit with control
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 air fan
equipped with energy-saving, stepless EC direct current motors.
Exhaust filter
Slide-in frame equipped with a Z line filter. Filter cell with pleated filter medium, fully incinerable and metal-free.
Heat pump unit
Heat pump unit equipped with a fully hermetic rotary piston/scroll compressor, evaporator, epoxy resin-coated condenser; bypass flap, condensate pan with drain
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.
