High-Temperature Water-Cooled Screw Chiller
100–300 RT • Cooling & Heating • Hot Water up to 185°F
EXINDA’s next-generation high-temperature water-cooled screw chillers deliver both cooling and high-temperature heating in a single VFD-driven platform. With hot-water outlet temperatures up to 185°F (85°C) and cooling capacities between 100–300 tons, these units are engineered for applications where conventional chillers cannot meet performance or temperature requirements.
Powered by an efficient screw compressor with real-time compression-ratio optimization, the system provides fast loading, quiet operation, and exceptional part-load efficiency, making it ideal for comfort cooling, process loads, and mission-critical facilities.
EXINDA High-Temperature Water-Cooled Screw Chiller
The EXINDA high-temperature water-cooled screw chiller is designed to deliver reliable cooling and high-temperature heating for industrial, commercial, and mission-critical applications. With a wide capacity range (100–300 tons) and hot-water production up to 185°F (85°C), this system supports air-conditioning, hydronic heating, domestic hot water, and process loads in a single integrated platform.
The fully VFD-driven screw compressor continuously optimizes compression ratios, ensuring excellent efficiency across all load conditions. The chiller maintains quiet, adaptive performance and includes fast-loading capability, allowing cooling or heating recovery within seconds after a power interruption.
Using R515B, a low-GWP next-generation refrigerant, EXINDA supports higher efficiency and sustainability targets while reducing environmental impact compared to traditional refrigerants.
