Complaint
The design and manufacturing process of the air cooled screw type water chiller and heat pump unit strictlyfollows the national and related industry standards. The unit adopts high-quality, highefficiency semi-hermetictwin-screw compressor. Through optimized design, reasonable configuration and careful assembly, the unit hasextremely high operational reliability.
This series of units uses air as the cold (heat) source and water as the refrigerant. They are divided into coolingonly type and heat pump type according to their functions. The heat pump type unit is one unit that integratescooling and heating functions. When the unit is equipped with a heat recovery device, it can also provide domes-tic hot water for users while cooling.
