Our company produces water-cooled screw chillers with a wide refrigeration range (98kw~991kw optional, if you are unsure about the selection of water-cooled screw chillers, you can directly contact us for the best solution), compact structure, stable operation, affordable price, and long service life. We are your trusted manufacturer of water-cooled screw chillers. Features: 1. Compressor Selected BITZER (Büssel, Germany), HANBELL (Taiwan Hanzhong), RefComp (Italian Lai Fukang) and other imported brand-name semi-closed screw compressor. It has the advantages of stable and reliable operation, high efficiency and low failure, good performance, low vibration and low noise, energy saving, convenient maintenance and long service life. According to customer needs and cold tonnage size, single or multi-machine combination. The compressor can be alternately operated according to the load, and the automatic energy regulation (25%-50%-75%-100%) balances the running hours of each compressor, which greatly prolongs the service life of the chiller. 2, evaporator It is a shell and tube evaporator designed and produced by Dongyuejin Refrigeration. The evaporator copper tube adopts an internal and external threaded reinforced tube. The surface of the copper pipe is threaded, the outer surface of the copper pipe is smooth, and the cooling effect is good. The evaporator body is insulated by a 25 mm thick PE insulation board, and no condensation occurs, and the loss of cooling capacity is small. 3, the condenser It is also a shell and tube condenser produced by Dongyuejin Refrigeration. It uses a copper tube imported from abroad to process into a trapezoidal low-ribbon tube to enhance heat transfer capacity. The surface of the copper tube is smooth, which reduces the water pressure and is easy to clean and maintain. 4, protection device The protection devices for water-cooled screw chillers are: compressor delay start protector, overload protector, high and low voltage protector, temperature control switch, antifreeze switch, fuse plug, electronic time protection safety valve, compressor overheat protector, compression The machine frequently activates the protector and the abnormal indicator to ensure the normal operation of the unit. 5, intelligent computer control system High-intelligent PLC and PC-level computer control system can be used for remote monitoring and control. It has multiple functions such as automatic loading and unloading, time switching and recording of fault causes. It is easy to operate and the host and power supply are connected. Low failure rate, high safety factor, simple installation, system control can be adjusted instantly, intuitive and reliable. 6, frozen accessories All the frozen accessories are selected from the world's top brands such as SPORLAN (American Polish), ALCO (American Eco), DANFOSS (Danfoss Denmark), etc., with excellent performance, safety and environmental protection.
