oil level switch (for screw unit), etc. can protect the function.
The PLC controller is a standard provided component. It can automatically decide the compressor
quantity to be used based on actual need of refrigerant capacity, average the running time
between each compressor, save the power. All of these will guarantee an over 30% longer
usage than single compressor condensing unit.
It has a unique low environment condensing pressure monitor system which guarantees a stable
functioning when there is a low ambient temperature, lack of oil feeding or oil flow warnin
High efficiency gas liquid separator is used, with a unique pipeline design, it can effectively
minimize the possibility of liquid strike.
The “Pressure Vessel Certificate” approved reservoir is provided as well as the safety relief valve.
