Evaporative Cooled Screw Chiller Unit

As a reliable manufacturer, Lynxcool develops Evaporative Cooled Screw Chiller Unit to deliver premium chilled water solutions for both industrial and commercial scenarios. By integrating evaporative condensing technology, twin-screw compressors and intelligent microprocessor control system, the chiller achieves outstanding energy-saving cooling capacity for diverse usage scenarios.

Meanwhile, it effectively lowers overall installation investment and daily operation costs. It is widely applicable to industrial production processes, HVAC systems and cold chain pre-cooling projects. Compact in structure, outstanding in performance, the whole unit can be fully regulated through microprocessor HMI.

Key Features and System Advantages

Evaporative Condensing Technology

Unlike traditional air-cooled chillers, the Lynxcool Unit uses a counter-flow spray-and-coil condenser. Evaporation reduces condensing temperature by 5–8 °C compared with air-cooled units at the same dry-bulb ambient, boosting COP by up to 20%. Lower condensing pressure reduces compressor workload and improves part-load efficiency.
