Variable Frequency Screw Chiller – Product Introduction
The Variable Frequency Screw Chiller adopts a
semi-hermetic screw compressor combined with VFD (Variable Frequency Drive) technology,
enabling precise capacity control according to real-time load demand.
By operating at different frequencies (30Hz / 40Hz / 50Hz),
the unit significantly improves part-load efficiency and reduces energy consumption.
Equipped with an electronic expansion valve, high-efficiency shell & tube heat exchangers,
and a complete safety protection system, the chiller delivers stable operation,
low noise, long service life, and excellent reliability.
It is especially suitable for industrial and commercial applications with fluctuating cooling loads.
