Product Description
Withair® is proud to offer an extensive line of water-cooled screw chillers ranging from 33 to 1,000+ tons. The water-cooled screw chillers feature a variety of models and options engineered to fit a wide range of applications. Withair® water-cooled screw chillers are ideal for customers who are focused on high energy efficiency, superior reliability and long equipment life. Withair® products within the unique portfolio are designed to help lower environmental impact with next-generation, low global warming potential refrigerants and high-efficiency operation.
Withair® water cooled screw chiller is the mature products which are equipped with newly-developed semi-hermetic screw compressors and use dry type or flooded type evaporator, which result in lower noise and lower vibration, reliable long period operation, and installation feasibility on any floor of the building.The units are composed of a compressor(s), a condenser(s),a direct-expansion water cooler, a electronic expansion valve(s),and auxiliary and control equipment.Optimized system design and enhanced heat exchange efficiency makes the unit working best under both full load and partial load. Every chiller is fully factory tested and gas charged in the factory before dispatch. It' s good choice for hotel, shopping mall, hospital, factory, cinema and other civil architecture air conditioning system. Besides, it is widely used in plastic industry, electroplating industry, food processing,chemical industry and other process cooling applications of modern manufacturing industries which needs a lot of chilled water.Stepless capacities can be customized.The units can be operated with the utmost simplicity.
