The Expert-D series water-cooled chiller units are equipped with dual scroll compressors and use high-efficiency R410A refrigerant with zero ozone depletion potential. The dual-compressor design allows the unit to operate at half capacity in situations where the demand is low, significantly reducing electricity consumption. Additionally, in the event of a compressor failure, the unit continues to operate at half capacity, preventing the process from coming to a complete halt. Compared to completely independent devices, they have lower initial investment costs. They also feature high temperature sensitivity, an optional colored touchscreen control panel, and integrated hydraulic module for quick and easy installation.
