QBE

The new range of QBE chillers has been designed to specifically meet industrial requirements and provide an accurate control of the chilled water temperature with the absolute reliability of continuous operation (with the option of hot gas bypass valve). It is particularly suitable for process cooling such as plastic moulding and extrusion, laser cutting, precision engineering, pharmaceutical and food industry etc.

The range consists of 12 models with cooling capacities from 2 to 25 kW and is designed for outdoor installations (QBE002 excluded and QBE003÷007 optional).

All standard units are equipped with:

• Hermetic rotary, scroll or reciprocating compressors
• Copper coaxial evaporator or stainless steel brazed plates
• Micro channel condenser in aluminium with epoxy coating
• Atmospheric pressure tank
• Electric pump with non-ferrous materials
• Water pipes in copper and PVC
• Electrical panel Manufactured according to the EN 60204 standard
• Microprocessor controller (electronic thermostat for QBE002)

The steel frame and panels are externally powder coated, making QBE suitable for outdoor and weather-proof installations. All fasteners are in stainless steel or electro-galvanized.

The panels are easily removable allowing access, allowing access inside the unit for maintenance and repair.

The clear arrangement of the components, the simple composition of the refrigeration and hydraulic circuit and the identification of cables in the electrical system, assist the users normal operation. All models are equipped with lifting hooks. The QBE008÷025 models are equipped with lifting holes on the base and allow easy handling of the machine.

As an alternative to R407C, the QBE range is available with R513A ecological refrigerant gas, with low environmental impact, with a GWP (global warming potential) of 631.
