Overview
Our high-efficiency full falling-film water-cooled screw chiller covers 70 RT to 470 RT (about 246–1,650 kW) across 52 standard specifications. It pairs an industry-leading twin-rotor screw compressor with full falling-film evaporation technology to deliver high efficiency at full and partial loads, using environmentally-friendly R134a refrigerant.
Inverter-driven versions further cut part-load consumption for buildings whose load swings through the day — the ideal choice for large commercial projects and industrial process cooling.

Packing & Delivery
Units are packed in cartons with wooden case or crate reinforcement engineered for sea freight and transshipment handling. Accessories, controllers and spare parts are consolidated into the same delivery, so your installer has everything on day one.
FAQ — Water-Cooled Screw Chiller
What is falling-film evaporation and why does it matter?
Refrigerant is distributed as a thin film over the tube bundle instead of flooding it — improving heat transfer and reducing refrigerant charge, which raises efficiency at both full and part load.
Do you support installation and commissioning?
Yes. We provide on-site installation guidance and commissioning support, plus operator training for plant staff.
