Water cooler WVY Series

The RCUF-WVY Series, which features R134a refrigerant, offers cooling capacities ranging from 155 to 520RT. It operates with high-efficiency cooling, achieving up to EER 5.9, while being designed to meet stringent environmental standards and ensure long-term durability. Hitachi proprietary G-Type Semi-Hermetic Twin-Screw Compressor and VSD In 1979, Hitachi pioneered the first semi-hermetic twin-screw HVAC compressor. Since then, they've supplied over 200,000 units. The WVY series employs Hitachi's latest G type R134a compressor, offering enhanced value to customers. • In-house developed rotor minimizes internal refrigerant leakage during compression. • Semi-hermetic structure with built-in motor eliminates coupling design, preventing refrigerant leakage. Refrigerant-cooled motor reduces failures, extending unit life. • Adequate oil supply to compressor ensured by advanced, pressure-differential driven oil system. No need for oil pump design reduces parts, improving reliability and maintenance. • 15-100% stepless capacity control via variable speed and slide valve. • The unit's variable speed drive reduces power grid impact by minimizing inrush current at startup and significantly improves part-load efficiency. Oil System The WVY series features an external oil separator for efficient oil separation from the refrigerant system, enhancing system efficiency. It incorporates a Venturi tube for an advanced pressure-differential driven oil system that returns oil from the sump to the compressor, ensuring constant oil supply. An oil filter in the pipeline prevents particles from entering the compressor.
