Air cooled liquid chillers and heat pumps with storage tank and pump, axial fans 18 kW÷20 kW - Maxa

TECHNICAL FEATURES

• Compressor. Scroll ermetic compressor, complete with overload protection (klixon) embedded in the motor and crankcase, if needed, installed on rubber vibrations absorbing.
• Fans. Axial fan type low ventilation and special wing profile, they are directly coupled to external rotor motors with protection grade IP44, and a safety fan guard fitted on discharge air flow.
• Condenser. Copper tubes and aluminium finned coil, complete with moisture drain pan in the heat pump version.
• Evaporator. In AISI 316 stainless steel brazewelded plates type, built- in the storage tank.
• Managing system and microprocessor regulation.
• Electronic proportional device to decrease the sound level, with a continuous regulation of the fan speed. This device allows also the cooling functioning of the unit by external temperature till -20°C.
• Water circuit. The circuit, in copper tubing, includes: water differential pressure switch, manual air release valve, insulated tank, pump, safety valve (3 bar), gauge, plant charge and discharge shut off valve and expansion vessel inserted in the storage tank.
