Product Description

Water cooled screw cascade chiller

Products Features
This series chiller lowest outlet water temperature can reach -80ºC.
Low temperature and super low temperature chiller is our technical staff after decades of experience in the designing of middle low temperature chiller, learned domestic and abroad experience, has the advantages of high efficiency, energy saving and environmental protection, high reliability etc..
1. Wide temperature range: refrigerant temperature range is -35~-80ºC.
2. High reliability: the semi hermetic screw compressor, improve the efficiency of the compressor operation, while avoiding the open type compressor leak, reducing refrigerant add and seal replacement, upgrade products for many years running.
3. Full automatic control: the use of advanced SIEMENS PLC control technology to achieve full automatic operation.
4. Energy-efficient: The use of semi hermetic screw compressor with economizer operation, improve the operation efficiency, at the same time, low temperature and intermediate level using efficient imported heat exchanger, to ensure that the unit load and full load can be efficient and energy saving operation
5. Energy regulation: machine can realize 4 level 25-50-75-100% and 25%~100% stepless regulation.
6. Professional and technical energy saving operation scheme: according to the different requirements of customers, we can customize the freezing technology for customers, to provide the appropriate professional products.
