Unit description AW HT is an ideal solution for systems with heating radiators, where the water high temperature is needed. The EVI technology compressor with additional steam injection in the compressing cycle assures a water temperature of 65°C and operating limits as low as -20°C. Neither probes nor connections pipes to wells are needed; the installation is simple, this is a suitable solution for all applications. Version AW HT - High temperature air source heat pump for water heating up to 65°C, and operating limits down to -20° external air temperature Features Structure and base in hot-dip galvanised steel with epoxy powder paint finish. High efficiency, low pressure drop AISI 316 stainless steel plate heat exchangers, fitted with heating element to provide frost protection. High efficiency cycle EVI Hermetic Scroll Compressor (with hot gas direct injection into the compressor) to reach 65° C, with the crankcase heater and thermal protection Finned coils made with copper pipes and aluminium fins with large exchange surface area (100% fully quality tested); sub cooling circuit to prevent the icing at the basement Axial electric fans, external rotor, 6-pole electric motor fitted with thermal protection, housed in aerodynamic conveyor profile with safety grill A condense collecting tray within water discharge Modulating electrical resistance to avoid freezing of the base; the resistance is located between wing and base exchanger to improve and facilitate the flow of water during defrosting Coil protection grille Soft starter for 230V units /ms and 400V units /ts Phase sequence control relay for three phase models
