HWE - Reversible Heat Pump

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. All standard units are equipped with:

• Hermetic scroll compressors
• Stainless steel brazed plates heat-exchanger
• Copper and aluminium ventilated coils with hydrophilic treatment on fins
• Fans with step control
• Microprocessor controller (electronic thermostat for QBE002)
• RS485 port for modbus connections

Theparticular architecture of the aeraulic section (the fans are confined in a protected volume) allows safely access to the hydraulic section and to the compressor’s housing.

The clear arrangement of the components, the simplicity of the refrigerant and hydraulic circuit and the identified cabled in the electrical system, assist the users normal operating schedule.

Control and/or maintenance operations could be carried out when the machine is operating and in total safety.

As an alternative to R410A, the HWE range is available with eco-friendly R454B refrigerant gas, with low environmental impact and GWP (global warming potential) of 466.
