The Clivet SCREWLine4 WDH-iK4 series represents a major advancement in water-cooled liquid chiller technology, specifically engineered to utilize the lower GWP refrigerant R513A. This series is designed for high-efficiency operation, boasting an impressive SEER rating of up to 8.60. By integrating advanced inverter screw compressors and a specialized spray shell and tube evaporator, the WDH-iK4 significantly optimizes thermal exchange, reducing refrigerant charge by 40% compared to traditional flooded exchangers and allowing for evaporation temperatures that closely mirror supply water requirements. Built for versatility, the WDH-iK4 line supports diverse installation needs with capacities ranging from 340kW to 830kW in single-compressor configurations, scaling up to 1520kW in dual-compressor setups. Users can select from three dedicated operating modes—cooling only, heating only, or water circuit change-over—to suit specific climate control demands. Furthermore, a super-silenced acoustic configuration is available for applications where noise reduction is a critical priority, ensuring the system provides both superior performance and quiet operation in sensitive environments.
