A water cooled screw chiller is like a giant refrigerator for buildings. Instead of keeping food cold, it keeps entire buildings comfortable. Additionally, these machines use water to remove heat more effectively than air-cooled systems.
"Water cooled screw chillers can save up to 30% more energy compared to air-cooled systems."
— Air-Conditioning, Heating, and Refrigeration Institute (AHRI)Water cooled systems work better because water removes heat faster than air. Moreover, they make less noise during operation. Furthermore, they last longer and need fewer repairs.
Water removes heat 4 times better than air
Perfect for hotels and hospitals
Less wear and tear on components
Works great in hot weather

Our Water-Cooled Screw Chiller Units are widely used in commercial buildings, healthcare, industrial production, and district energy projects, where stable cooling and high efficiency are critical.
200–600 kW
Hotels require a quiet, stable, and energy-efficient cooling system to ensure guest comfort. Water-cooled screw chillers provide low-noise operation, steady chilled water supply, and excellent energy efficiency for guest rooms, lobbies, restaurants, and spas.
600–1200 kW
Healthcare environments demand precise temperature and humidity control for patient comfort, laboratories, and surgical rooms. Water-cooled chillers deliver stable and reliable cooling 24/7, with redundancy options ensuring uninterrupted operation critical for medical safety.
400–1000 kW
Business towers and mixed-use complexes require energy savings with flexible load management. Water-cooled screw chillers integrate seamlessly with Building Management Systems (BMS), allowing intelligent load adjustment and zone cooling.
800–1800 kW
Large commercial areas face high cooling loads during peak hours. Water-cooled chillers handle fluctuating demand efficiently, offering continuous comfort in large open spaces. Their high efficiency lowers operational costs for extended-hour facilities.
1000–2500 kW
Factories and processing plants require robust, heavy-duty cooling systems for both process cooling and indoor climate control. Water-cooled screw chillers are designed for long-term continuous operation, even in challenging environments.
1500–3600 kW
Data centers need precise, reliable, and uninterrupted cooling to protect sensitive IT equipment. Water-cooled screw chillers ensure tight temperature control, high redundancy, and continuous operation under partial and full load.
2000 kW+
For airports, large industrial parks, or city-wide district energy networks, water-cooled screw chillers provide centralized cooling and heating solutions. Their high efficiency and scalability allow them to operate as the backbone of sustainable urban energy systems.
Fully Customizable: All systems can be customized in terms of capacity, heat exchanger type (flooded/falling film), refrigerant, and frequency (fixed or inverter) to perfectly match project requirements.
