Product Description
SHWE/SCWG Water Cooled Screw Chiller
90-550+RT Continuous-Duty Platform with Extended-Life SKF-Bearing Screw Compression for 50,000+ Hour Service Intervals
Overview
The Midea Water Cooled Screw Chiller platform serves facilities demanding uninterrupted thermal management. The SHWE series (R134a fixed-speed) covers 94.6-565.6RT (332.6-1,988kW), while the SCWG series combines R513A variable frequency and R134a fixed-speed pathways across 90-550+RT capacity.
These chillers integrate semi-hermetic twin-rotor screw compression with precision-assembled bearing packages engineered for continuous service intervals extending beyond 50,000 hours. Flooded-shell evaporator geometry promotes effective thermal exchange, while the internal lubrication architecture—including integral separator and dual-return pathway—ensures consistent compressor lubrication without external mechanical support.
Infinite capacity modulation responds dynamically to actual cooling requirements, while electronic expansion control achieves sub-degree temperature stability. The color touchscreen human-machine interface provides straightforward operation with predictive load management functionality. Variable frequency models incorporate controlled motor starting to protect electrical distribution infrastructure from transient loading.
