Semi-hermetic Screw Compressors in Parallel Condensing Unit

Advantages：

1.Equipped with updated 5:6 asymmetric rotor semi-hermetic screw compressor, which provides with high efficiency, long life, small vibration and low noise

2.With multi-level energy regulation, energy can be adjusted according to the change of cooling load, which can effectively reduce energy consumption

3.The unit has multi-protection for compressor coil temperature, exhaust temperature, low oil level, oil pressure difference and high-low pressure of the system.
