Chillers

Water-cooled low-temperature ethylene glycol brine unit (dual unit)

次 View times: 16160 times

Equipment details

Medium and low temperature ethylene glycol brine unit can produce low temperature freezing liquid at 0 ~ -45 ℃. As for the low-temperature chiller using screw refrigeration compressor, we call it screw-type low temperature chiller. The water-cooled screw chiller is introduced here. It is mainly used in ink printing plants, food processing plants, automobile manufacturers, building mixing stations, petrochemical plants, pharmaceutical factories, leather factories, textile factories, central air-conditioning chillers and other high-power low-temperature occasions.
Performance characteristics of screw cryogenic chiller:
1. Durable and energy-efficient compressor
Selected original imported semi-hermetic screw and semi-hermetic reciprocating compressors such as BITZER (German Bitzer), HANBELL (Taiwan Han Bell), RefComp (Italy Lefcon) 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 and alternately run according to load changes, automatic energy adjustment (25% -50% -75% -100%), balancing the hours of operation of each compressor, greatly extending the life of the chiller.
2.Internal and external screw type enhanced tube evaporator
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. Imported copper tube to make condenser
The condenser uses copper pipes imported from abroad and is processed into trapezoidal low-rib tubes to enhance heat transfer capacity. The surface of the copper pipes is smooth, which reduces water pressure and is easy to clean and maintain.
4. Powerful protective device
Protection system devices include: 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, compressor frequent start protector And abnormal indicators to ensure the normal operation of the unit.
5. Intelligent computer control system
The company has developed a highly intelligent PLC and PC-level computer control system, which can be used for remote monitoring and control. It has multiple functions such as automatic loading and unloading, timing of switching on and off, and recording of the cause of the fault. The operation is simple and the host is connected to the power supply. Low failure rate, high safety factor, simple installation, system control can be adjusted instantly, intuitively and reliably.
6. Foreign imports of frozen parts
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.
