Screw Compressor Terminals DB-S322

  
  • Description

The Screw refrigeration compressors are now more and more widely used because of its large colling capacity, less wearing parts, less maintenance work, high volumetric efficiency, low temperature of exhaust air and easy adjustment of cooling capacity.

Compressor terminals are important part for screw refrigeration compression system, it is a small spare part of a compressor, but works for power connections. So terminals for screw compressor is required for high performance for electricity transfer constantly and stable.

Surface Treatment: Environmental friendly chemical nickel plating technology is applied on the surface treatment of screw compressor terminal, the nickel plating thickness is about 5-10μm.
