HRI-E TWO F

• Fire-resistant expanded polypropylene enclosure with zinc-coated side plates.
• Duct connection ports of nominal diameter 150 mm.
• 2 x EC brushless motor with shaft turning in ball bearings; 3 speeds, which can be set independently at the moment of installation and monitored from a remote control panel connected by wire, with LCD display.
• Air flow settable between 100 m3/h and 365 m3/h.
• Ultra high-efficiency counter-flow type heat exchanger fashioned from moulded plastic (PS).
• 100% by-pass, automatically operated with filtration.
• Automatically activated system designed to prevent icing of the heat exchanger.
• Mod-Bus module with RS485 connection port in slave mode.
• Compatible with operation piloted by Vortice ambient sensors: temperature (C TEMP), relative humidity (C HCS), presence (C PIR) and smoke alarm (C SMOKE). With operation interlocked to sensors, the local control functions are inhibited: the appliance continues to operate at minimum speed as long as the reference parameters monitored by the connected field sensors remain below the relative threshold values; when these values are exceeded, the appliance will switch to the maximum speed setting, which is then maintained until such time as normal ambient conditions are restored.
• 2 x F5 filter (alternatively, option of F7 filter on outlet duct).
