Falling film screw chillers are known for delivering strong energy efficiency and dependable cooling, even in demanding conditions. Rather than fully flooding the evaporator, they let the refrigerant form a thin, even film over the heat exchange tubes, flowing gently downward under gravity. This design enhances contact with the tube surface, which in turn improves evaporation, strengthens heat transfer, and lowers the amount of refrigerant needed. In practice, this means they adapt well to processes where temperature precision matters, cooling reaction vessels in chemical plants, keeping fermentation tanks at the right level in breweries, or stabilizing conditions in automotive production lines. They are also widely used in large-scale central air-conditioning systems, district cooling plants, ice storage projects, and similar applications that need efficient cooling and optimized power consumption.
