Feature of product

The compressor is adopt imported international brands which are high efficiency and energy save, like Bitzer Germany, Hanbell Taiwan, etc. Operation is smooth and steady, high efficiency, low failure rate, good performance, small vibration low noise, energy save, mantenance is convinient, long operation life and so on advantages. Can use single unit or multiple combination according to customer needs and cooling capacity.

Industrial PLC central control, compressor adjustable system, can accurately control unit refrigerating capacity and the cooling load matching, to guarantee the unit running at optimum efficiency, reduce the operation cost. The unit integrate with water break, low temperature, high and low voltage, antifreeze, lack of phase, delayed start, inverse phase, overload, motor overheating, oil pressure diffirence and multiple security protection and processing functions. With full English and Chinese operation interface, can be arbitrary set the unit running state, like electrification of domestic appliance.

The capacity control system can use four stages as 100%－75%－50%-25%, three stages as 100%－66%－33%, and stepless adjustable.

Unique built-in type oil pressure system, and ensure the compressor to keep the best lubricating effect without oil pump. Oil separator adopts double filtering method and have good effect, that make heat exchanger be in maximum capacity.

The internal thread copper pipe enhance the heat transfer effect, more energy efficient. Using the latest CAD/CAM design and processing technology, CNC processing center production, compact structure, small size, durable. The u-shaped heat exchange tube bundle can overall clean out internal water, convenient maintenance, prevent refrigerant leakage phenomenon

The unit can cooling water to - 10 °C, Available glycol aqueous solution or calcium chloride, sodium chloride brine solution as a cooling agent. There have pressure control and safety valve device of Refrigeration system to ensure safety operation. The operation of units have passed the professional test before send out from factory. With oil cooler, oil separator, economizer, the refrigeration efficiency increased 10% - 15% relative to the traditional low temperature water chiller, reducing operation cost.
