Compressor

Select semi-closed 5:6 asymmetric twin-screw compressor from world-renowned brand. The possibility of shaft seal leakage is zero. Using a rotating exhaust design, the latest development of the fourth generation line, optimize the circumference speed, excellent design of gear so that the unit has higher compression efficiency. Motor chamber compression chamber integrally cast, high precision. Double pressure compensated rotor housing, very strong, no expansion even in the state of high pressure, and it effectively reduces the noise.

Heat exchanger

The condenser and evaporator of this series unit adopts shell and tube heat exchanger, using new high efficient heat exchanger structure. Heat exchanger adopts the most advanced and efficient heat exchanger tube bundle with unique geometric characteristics and enhanced tube nucleate boiling required vaporization core, strengthened the flow disturbance inside the pipe, while delaying the scaling on the water side. The inner and outer walls are enhanced for heat transfer to achieve optimal performance. Compared to previous designs, the current unique design improves heat transfer efficiency by 30%.

Evaporator evaporation tube with inner grooved on outer concave tooth enhanced heat transfer technology, condenser tube with inner grooved cutter teeth technology, improves the evaporator and condenser heat transfer efficiency and the evaporation temperature, and improve the energy efficiency ratio for the unit.

PLC

A good Chinese-English interactive interface is to achieve automatic control function before the LCD display real-time statues of the machine work, precise monitoring unit operating at optimum state, the touch panel sealed, waterproof, dustproof, corrosion-resistant, long-key life. Equipped with cooling pumps, cooling water pumps and cooling tower fan interlock control function.

Low temperature chillers

SW series of low temperature chillers based on well-known brands as the host semi-hermetic screw compressor, built-in suction filter, oil filter, oil separators, safety valve and protection module, with no leakage, low noise, stable operation.
