Features of the Water cooled screw compressor type：1、Industrial water chiller world-brand compressor:Imported double screw series compressor. Double screw with gear ratio5:6 and advanced linear design. Energy-saving and high efficiency. Energy control can achieve the classification or non-classification energy control. With balanced design, the running is quiet and steady. The moving parts are dealt with strictly. Special design of the oil balanced block in the exhaust place. Long maintenance circle. Running with faults for more than 40000hours. Effective oil filter,its oil capacity brought out by the exhaust is less than 1.5%. It can effectively improve the two machines exchanging heat,saving more energy and durable.2、Industrial water chiller new and high effective evaporator: High effective inner grooved crooved copper can increase the heat transmission effect and it is energy-saving and of high efficiency. Using the latest CAD/CAM design processing technology and complete the CNC processing center manufacturing. Compact structure,small volume and durable. Heat-exchange tube bundle with U structure can clean the incrustation on the whole,easy to maintain. Dry evaporator, easy for oil recycling and improves its working life and reliability.3、 water chiller condenser using the latest efficient external threadcopper pipe; big heat dissipating capacity, small size. Using the latest CAD/CAMmachining technology, cooperate with the CNC machining center; with compactstructure, high reliability, good appearance, high efficiency and energy-savingability.
4、Industrial water chiller air cooled condenser: Air-cooled condenser has highentire piercing with reliable sheet turning quality. Secondary flanging, copperpipe and fin closely contact with high thermal efficiency.Adoptimported copper tube and auto bend welding; Greatly enhance the oxygentightness, get rid of the refrigerant leakage phenomenon; Especially suitablefor water shortage or high hardness of water quality.
5、Industrial water chiller microprocessing control system: Industrial PLC set central control; cooperate with the energy condenser.It can be timely and accurately control the unit refrigerating capacity and the cooling load matching, guarantee the unit running at optimum efficiency, reducing the operation cost. Internal integration with water, low temperature, high and low voltage, antifreeze, lack of phase, delaying start, the inverse phase, overload, motor overheating, and poor hydraulic multiple security protection and processing functions
