Multi-protection Design

>Multiply measures to ensure units operate normally and reliably:System current protection, High/low pressure protection, Temperature Asensor protection, etc.
■Three-phase protector can be customized.
■The unit is designed with the compressor rotation system: in the multi-system unit, the equipment adopts to activate the compressors one by one according to the time and the load, and according to the cumulative running time of the compressors,it gives priority to start the compressor which has the shortest running time,so as to ensure the balance of each
compressor's running time and to prolong the service life of the whole unit.
