The SHWE and SCWG series provide high-efficiency water-cooled screw chiller solutions engineered for commercial and industrial applications. The SHWE series utilizes fixed-speed compressor technology, while the SCWG series offers variable frequency drive options for superior part-load efficiency. Both series feature flooded evaporator design and intelligent capacity control for stable, efficient operation.
