HWA1-A

The HWA1 & HWA1/H range offers high efficiency air-cooled chillers and heat pumps. Available in 24 sizes they are designed for outdoor installation and offer simple maintenance management. Designed to withstand outdoor conditions the units are built with hot-dip galvanized or polyester powder coated steel sheets making them resistant to atmospheric agents.

The unit configurations includes a uniform refrigerant circuit with irregular tandem compressors or an irregular refrigerant circuit with an even larger compressor, allowing control of more phases.

The scroll type hermetic compressor is complete with internal thermal protection which, through the interposition of special rubber supports, isolates it from the structure. All the compressors are complete with a polyester oil charge, suitable for operation with R410a refrigerant.

The control of the cooling capacity is achieved through capacity steps in a number equal to the number of compressors installed in the unit. The tandem connections contain an oil equalisation line with a level control light.

A differential pressure switch, installed on the water side, ensures the presence of water flow avoiding the formation of ice inside. The electric motor with external rotator activated by magnetic commutation enables efficiency increase of up to 70%, increasing the working life of the machine and or reducing its electrical consumption.
