World Famous Brand Compressors:
Original semi-enclosed screw compressors such as the Italian "Laifu Kang", Japan "Kobelco", "Taiwan Fusheng" and "Han Zhong". Efficient valve energy control, automatic classification or stepless energy adjustment. Balanced design runs super quietly. Strict handling of moving parts, long service intervals, and more than 40,000 hours of trouble-free operation. High-efficiency oil separator, exhaust gas with less than 1.5%. New high-efficiency evaporator/water-cooled cooler: The latest high-efficiency internal-threaded copper tube enhances the heat transfer effect and is more energy-efficient. CAD/CAM machining technology is completed and the structure is compact. The refrigerant is evenly distributed and the heat exchange efficiency is improved. The U-shaped heat exchange tube bundle can be internally pumped to clean the internal scale for easy maintenance. Evaporator-type, easy to return oil, improve compressor life and system reliability. Easy to install: The compact unit has a small footprint, light weight, and easy handling. Balanced safety, low vibration, no complicated foundation, simple installation. A variety of performance tests have been completed before the factory and wiring has been completed, reducing installation time and costs. Run reliably: The motor uses the world's most advanced Japanese PTC thermal protection, making the protection more sensitive and more reliable. The interlocking control of the water system and the unit can be achieved. Compressor unloading step-down start, starting current is small. The unit uses multiple refrigeration circuits. Excellent control: PLC programmable controller, man-machine interface, full Chinese display. PLC adopts closed-loop direct digital control (DDC) to achieve full-process, fully automatic computerized control, making the group control more accurate and reliable. Automatic monitoring of cold water outlet temperature, automatic control of the spool valve through the PLC to unload, automatically adjust the compressor in a very small temperature range, reduce energy consumption. When the unit is started, climbing control is achieved by a microcomputer and the full load is quickly reached. With self-diagnosis function, when certain parameters are close to the limit value, certain protective measures are taken and an alarm is issued to prevent the unit from being damaged and reduce unplanned downtime. Automatically record the alarm conditions and the time of occurrence of the last ten unit failures, and send out processing instructions. Automatic protection function of the unit: compressor suction pressure too low protection, compressor discharge pressure too high protection, cold water ultra-low temperature protection cold water, cooling water cut water protection, motor overload protection, motor overheat protection, power failure protection (overvoltage, undervoltage , lack of phase, wrong phase sequence, etc., prevent re-start. Control Panel Display: Main unit operation status, cold water pump, cooling water pump status, cold water outlet water temperature, compressor suction pressure, compressor discharge pressure, compressor discharge temperature, compressor cumulative running time, unloaded status, time display function, fault display function . |
