If you are going to buy cheap and high quality water cooled screw chilling unit from one of the best water cooled screw chilling unit manufacturers,Website:http://www.wuxifangzhou.com, or you are going to check the price with a such factory, Fangzhou Water Cooling Equipment Co.Ltd is always at your service.Characteristics of product 1, Using the oil-cooling device of Fangzhou patent technology (Patent number.200810036745.8) and high efficiency separation technique of secondary oil, let the unit can efficient and stable operation under low temperature working condition, adapt to the requirements of industrial refrigeration widely. 2, Unique built-in oil hydraulic system, can let the compressor to maintain the best lubricating effect without oil pump, the oil separator adopts double filtering method, with excellent oil filting effect. 3, industrial-grade PLC control, match up the energy regulation system of compressor, accurately control the unit refrigerating capacity timely and the cooling load matching, ensure the running at the optimum efficiency, reduce the operation cost. 4, intemal multiple security protection and processing functions such as water breaking, low temperature, high and low pressure, phase loss, phase inversion, delayed start. Overlosd, motor overheated, oil pressure difference. 5, Full Chinese operation interface, menu-type hint, realize fully functional automation control, the unit running in the best condition. 6, The capacity control adopts four-paragraph (100% - 75% - 50% - 75%) hierarchical power control system, ensure the units play the best energy saving effect in part load, if you need precise control water temperature, all models can be stepless energy assembly control system according to user requirements. 7, Using the shell-tube heat exchanger of Fangzhou technical patent (patent no. :200920075199.9) to enhance heat transfer effect, more energy-efficient, processing technology ysing the latest CAD/CAM design, CNC machining center is completed, compact structure, and leak rate is extremely low, durable. 1.Table of cooling capacity calibration conditions: Chilled water inlet temperature is 12℃, Water outlet temperature is 7℃, Cooling water inlet temperature is 30℃, Water outlet temperature is 35℃;2.The scope of work of chillers: Chilled water temperature is 5-20℃;3.Power Format: 3P-380V-50HZ,recommended a three-phase five-wire system. Which allows the voltage fluctuation ±10℃. Allowing alternate voltage difference ±2%;4.The unit users programmable PLG series controller, touch screen interface operation interpersonal, we can use the programmable controller text;5.Noise measured at the host location for the front of 2 meters, 1.5 meters high, all around the four-point average.
