Hitachi GLS Chiller Unit Water-Cooled Cooling Only Standard/Inverter
Hitachi Global Life Solutions
Water-cooled chiller with inverter compressor that enhances water temperature accuracy.
Overview The inverter compressor improves water temperature accuracy. Enhanced performance during low-load operation achieves high energy efficiency. Additionally, module control functionality is standard equipment. Improved water temperature accuracy with inverter compressor The compressor's operating capacity is controlled by the inverter according to the load, enhancing the accuracy of the chilled water outlet temperature supplied to the load. Up to 8 modules can be controlled per group (maximum cooling capacity of 480 kW) Module control functionality is standard equipment. A dedicated controller for unit control is not required. (Input of the "system operation button" from the "local system operation kit" option or remote operation commands is necessary.) Unit control functionality Operates with the number of units appropriate for the load. (It is also possible to turn all units ON/OFF simultaneously without unit control.) Rotation function Monitors the operating time of each module and manages operating time. For further details, please contact us.
