Water-cooled Screw chillers feature: 
 ① using imported international brands BITZER Germany (Bitzer), HANBELL China Taiwan (Chinese bell) energy efficient compressor. 
 ② unit control system using programmable devices imported PLC, man-machine interface with LCD large-screen touch screen, intelligent human-machine dialogue, a lot of internal storage solutions and troubleshooting technical data, multilingual display unit running, much easier to unit operations management and maintenance; 
 Four-volume control can be used ③ (100% -75% -50% -25%) or three (100% -66% -33%) and non-stage control systems; 
 ④ unique built-in hydraulic system, no oil pump is the best guarantee to maintain compressor lubrication oil separator with double filtration, oil filtering effect is good, can play a maximum capacity of the heat exchanger; 
 ⑤ processed using the advanced industrial and professional internal and external steel tube expander technology, the whole process with CNC machining and programming CNC produced, to prevent refrigerant leakage phenomenon; 
 ⑥ use imported steel and the whole hyperbolic corrugated hydrophilic aluminum foil, high-speed drilling and other specialized equipment, is more closely exposed pipe with fins, heat transfer more efficient, with small size, light weight, reasonable structure, more compact, etc.; 
 ⑦ full range of the compressor volume ratio (VI = 2.2/2.6/3.0/3.5) for selection. Can effectively avoid over compression or compression caused by the lack of additional energy consumption; 
 ⑧ using compressor overheating, overcurrent protection, high and low voltage protection, frost protection, flow switches, phase sequence / phase loss protection and exhaust heat protection and other security protection system; 
 Water-cooled Screw chillers (-7 - 40 degrees) characteristics, cooling capacity, using the world famous imported compressor, low temperature performance, reliable and durable products for industrial applications based on design features built-frozen low-temperature circulating pump and stainless steel water tank extremely easy to use, all materials in contact with water corrosion resistant materials are used effectively to prevent rust and corrosion; microcomputer LED digital display controller with temperature display, set temperature, automatically adjust the cold water temperature and compressor protection delay function, the choice of brand name contacts, relays and other electrical components, with a perfect indicator, switches, operating at a glance, built-in electronic level indication and alarm, the operator control panel can control the water level in cold water tank, and timely pay, unique modular design, each single bit compressor system security, even if a system problem, and would not affect the normal operation of other systems. 
 Water-cooled Screw chillers and chiller can be divided into open, sealed (some called box chiller) and screw-type chiller. First of all make it clear, water-cooled chillers, cooling towers and have another installation of water pumps, hot water to extract heat. To achieve a better cooling effect. Open the chiller, but also the other installed a water tank sealed do not have to, because he built a water tank itself. Open usually installed in the workshop, the ease of maintenance, but not because of their appearance, so we had a sealed water-cooled chiller. Sealed water-cooled chiller is a box structure, easy to install, easy to use, in the current customer base of the more popular. But if you have very large cooling capacity requirements, then we must use screw-type chiller, and then we usually call chillers, most of the manufacturers, if you are required to achieve 100HP compressor chiller above, we recommend that you use screw-type chiller.
