Equipment details

Configuration of water-cooled screw chiller
1.Compressor
Selected original imported semi-hermetic screw compressors such as BITZER (German Bitzer), HANBELL (Taiwan Han Bell), RefComp (Italy). 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 life. According to customer needs and the size of the cold tonnage, a single machine or a combination of multiple machines is used. Compressors can automatically run alternately according to load changes, automatic energy adjustment (25% -50% -75% -100%), balance the operating hours of each compressor, and greatly extend the life of the chiller.
2.Evaporator
It is a shell and tube evaporator independently designed and produced by Simpson Refrigeration. The evaporator copper tube adopts internal and external screw type 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 25mm thick PE insulation board without condensation, and the cooling loss is small.
3.Condenser
It is also a shell and tube condenser produced by Simpson Refrigeration. It uses copper tubes imported from abroad to process trapezoidal low-ribbed tubes to enhance heat transfer capacity. The copper pipe has a smooth surface, which reduces the water pressure and is easy to clean and maintain.
4.Protection device
The protection devices of water-cooled screw chiller include: compressor delay start protector, overload protector, high and low pressure protector, temperature control switch, anti-freeze switch, fuse plug, electronic time protection safety valve, compressor overheat protector, compression The machine frequently starts the protector and abnormal indicator to ensure the normal operation of the unit.
5.Intelligent computer control system
Highly intelligent PLC and PC-level computer control system, which can be used for remote monitoring and control, with multiple functions such as automatic loading and unloading, timing switch on and off, and recording of the cause of failure; simple operation, the host and power supply connection. Low failure rate, high safety factor, simple installation, system control can be adjusted instantly, intuitively and reliably.
6.Frozen accessories
All the frozen parts are selected from the world's top brands SPORLAN (Spoland, USA), ALCO (USA), DANFOSS (Danfoss, Denmark), etc., with excellent performance, safety and environmental protection.
