HWE reversible heat pumps are air-cooled with axial fans and consist of 14 basic models with cooling capacities in the range of 13 to 140 kW. They are designed to specifically meet industrial application requirements and provide accurate control of chilled water temperatures with absolute reliability in terms of continuous operation.
Evaporator made from AISI 316 stainless steel brazed plate,
Copper and aluminium ventilated coils with hydrophilic treatment on fins
Flow sight glass with moisture indicator;
High pressure switch with manual reset;
Low pressure transducer with semi-automatic reset;
High and low pressure gauges
Pressure connections for checks and maintenance.
Hydraulic circuit. The hydraulic circuit consists of an internal evaporator and pipework. It features a differential pressure switch protecting the evaporator in case of water flow lack. All units can be equipped with an optional multistage centrifugal pump with steel impeller. All pump parts in contact with the fluid aire made from AISI 304 staniless steel compatible with up to 40% water ethylene glycol mixtures. The motor is a 2 poles ventilated asynchronous class F and is IP55 rated. Three different configurations of residual head pressure pumps are available (P2, P3 and P5), as well as double circulation pumps. Both atmospheric and pressurized tank versions are available, as well as non ferrous stainless steel one.
