For industries that need reliable low temperature process cooling on a large scale, water-cooled screw chillers deliver consistent performance in temperature ranges from -30 °C to 0 °C. They are widely used in non-ferrous metallurgy, electronics manufacturing, chemical plants, food production facilities, air separation systems, and hydrogen energy projects. Semi-hermetic screw compressors from Bitzer and Hanbell work together with high-quality refrigeration and control components from well-known international brands to maintain stable operation even in demanding, 24-hour production environments.
These water-cooled chillers are equipped with a PLC-based control system paired with an HMI touch panel allows operators to view real-time performance data, adjust temperature settings, and monitor alarms or maintenance prompts with ease. The interface can be configured for different languages and customized to match specific process requirements. Combined with years of industrial refrigeration design expertise, this flexibility ensures precise temperature regulation, stable operation under continuous workloads, and optimal energy use across varied operating conditions.
