Hitachi GLS Chiller Unit, Brine Water-Cooled, Low Temperature for Cooling Only, Continuous Control
Hitachi Global Life Solutions
Water-cooled low-temperature screw chiller designed to expand the lower limit of cooling water outlet temperature and achieve energy savings.
Overview Water-cooled dedicated screw (for low temperatures) equipped with a shell-and-tube condenser. By expanding the lower limit of the cooling water outlet temperature from 22°C to 17°C, we aim to achieve annual energy savings. Expansion of Usage Range By expanding the lower limit of the cooling water outlet temperature from 22°C to 17°C, we aim to achieve annual energy savings. Simplification of Legal Procedures such as High-Pressure Gas Manufacturing Notifications There are no products subject to permit application. Cycle Configuration The compressor is equipped with an A-type screw compressor featuring a cyclone oil separator, the brine cooler uses a plate heat exchanger, and the condenser employs a shell-and-tube heat exchanger. Control Functions Equipped with control functions such as momentary power interruption recovery control, automatic power outage recovery control (optional), and demand control functions.
