Piston Compressor Terminals DB178E

  
  • Description

Semi-hermetic compressor terminals are mainly used in commercial and industrial refrigeration. They carry large capacity and can continuously supply high energy. The terminals, which are small spare part for compressor, but they are required high performance for transfer high power constantly and stable.

DB178E terminal plate fits for Copeland Piston Compressor ,their glass-to-metal sealing technology is a core process for high insulation resistance.

Environmental friendly chemical nickel plating technology is applied on the surface treatment of semi-hemetic compressor terminal, the nickel plating is about 5-10μm thickness.
