CWE

CWE are water chillers air-cooled with axial fans and consist of 13 basic models with cooling capacities from 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
• Plate evaporator
• Water strainer
• Micro-channel aluminium or finned tubes condensers
• Fans with step control
• Microprocessor controller (electronic thermostat for QBE002)
• RS485 port for modbus connections

EASY MAINTENANCE

The particular 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 CEN range is available with eco-friendly R454B refrigerant gas, with low environmental impact and GWP (global warming potential) of 466.

CWE chillers are available, in option, with the innovative HEAT BALANCE variable heat recovery system. The system is self-adaptive, able to satisfy different hot water demands.
