Low Temperature Air-cooled Screw Unit Water-cooled Chiller
Product introduce
There are both twin screw and single screw types of low-temperature screw refrigeration units, and now the widely used one is the twin screw type. Its compressor is the most advanced, which is an asymmetric twin screw, and all of them are imported from abroad, so the compressor quality is very stable and very energy-saving.
