Hitachi GLS Chiller Unit Matrix Advance Water-Cooled Refrigeration Only
Hitachi Global Life Solutions
Water-cooled screw chiller using low GWP refrigerant R1234yf, responding to environmental and energy-saving needs.
Overview A water-cooled, cooling-only screw chiller unit that pursues energy efficiency and serviceability. It features a lineup of models that use the new refrigerant R1234yf, taking environmental impact into consideration. Features - Stability of supply water temperature and reduction of running costs. - Reduction of initial costs, including measures against harmonics. Adoption of low GWP refrigerant [HFO] R1234yf R1234yf is a refrigerant that reduces the global warming potential by over 99% compared to the conventional refrigerant R134a. It achieves a significant reduction in environmental impact with a refrigerant charge equal to or less than that of conventional models (RCF_WZT1 (C)). No need to comply with the Fluorocarbon Emission Control Law Equipment using "R1234yf" is exempt from the Fluorocarbon Emission Control Law. Therefore, there is no legal requirement for maintaining inspection records or reporting leakage amounts. Additionally, as a measure for specific inert gases, the machine room (indoor) where the chiller unit is installed must have a mechanical ventilation system. For further details, please contact us.
