water cooled screw chiller

Water cooled industrial chiller main configuration:

Water cooled screw chillers adopt double screw

Adopt original import of semi-closed double screw compressors, using third generation current of compressor field 5:6 asymmetric tooth shape rotor save energies, simple  structural design, less parts, double screw structure, high precision mechanical structure components uniform, friction resistance is reduced to the minimum, for the double screw, fine processing, close occlusive, Running smooth and quiet durable, due to the pressure differential injection mode, save oil cooler, pump etc multifarious oiling system, easy maintenance.

The condenser and evaporator

Adopt high horizontal shelland tube condenser and evaporator, simple structure,stable heat exchanger, high efficiency and energy saving, simple and convenient maintenance etc.

Computer controller

Humanized LCD PLC operation interface, menu type, protect perfect control system, monitor the operation state, ensure the unit with the best efficiency, reduce operation running costs.

Protection function

Compressor overload, coil overheat protection , exhaust temperature exorbitant protection, low temperature protection., Compressor.start-stop  Frequent protection, abnormal voltage protection, and Pressure differential protection and  Processing function etc.

The characteristics of water-cooled screw chillers:

1.The highest efficiency of semi-enclosed compressors, the heart of units adopt imported superior screw compressor, its 5:6 super efficient screw compressor, than the average 20-30%. high efficiency, easy maintenance, precise capacity control and widely application scope.

2.Microcomputer accurate control temperature, unit of microcomputer controller using the ultra big screen dot matrix LCD display, has the good human-machine conversation interface realize full functional automation control. LCD display screen instantly shows machine working condition, accurate monitoring group operating in the best form, its light touch panel sealed, waterproof, dustproof, corrosion, button long life. Grading and non-polar energy control, used for general air conditioning system, equipped with 100%, 50%, 75%, 25% grading systems. ensure energy control unit under partial load when maximum energy saving effect. But if you need precise control temperature, can according to user requirements, all models can be assembled steplessly energy control.
3. High efficiency, high heat exchanger using corrugated pipe, plus efficient screw compressor and guarantee of efficiency operation of the unit. The most reliable protection and auxiliary parts
4.units has the following components to prevent any operation fault: a compressor protect timer, over-current relay, compressor motor temperature sensor, prevent freezing thermostat, depending on the liquid mirror, oil heater, compressor anti-phase protective relays, high and low voltage protection, exhaust temperature protection, safety valve, soluble plug.

5. latest asymmetric rotor tooth shape
6. Four segments or no KNN capacity control system.
7. Built-in differential pressure oil-supplied lubrication system.
8. Low vibration, low noise.
