Superior performance:
1.The main International advanced semi-closed screw compressor in which electric motor and compressor are organically integrated to ensure no leakage of the shaft sealing.
2.Control programs for start and stoppage are applied to double or multiple compressors so as to balance the load and extend the service life of each component.
3.Several refrigeration circuits are provided for double or more compressors. When one circuit needs maintenance, other circuits can work properly as alternative circuits.
4. The compressor is started with unloading and decompression to avoid the impact to the power grid.
5.The vortex and propeller of the compressor is designed to ensure extremely low noise.
6. H/W structural design, favourable thermal radiation.
7.Heat exchanger has the national pressure vessel certificate.
Specification:
1. Refrigerating operation conditions: freezing water inlet temperature 12 degree C, outlet temperature 7 degree C,environment temperature 35 degree C.
2.This series of the unit is controlled by programmable PLC controller and temperature controller which imported from abroad.
3. Power supply specification: 3P-380V-50Hz,Three-phase four-wire power supply is recommended, with the allowable voltage fluctuation of ±10% and frequency fluctuation of ±2%..---other power supply, please ask the parameter directly from our company.
4. The noise is measured at the position1.5 m in height and 2m in front of the unit. The noise measurement takes the mean value of four values measured at the left and right, in the front and at the rear of the unit.
