WGC - Wet Gas Compressor

Compressor Processes Liquids | Works With Any Lift System | No Pneumatic Valves or Vessels | Automated Capacity Control | SkyView Reporting | Set & Forget PLC Control

After extensive research and development, we are thrilled to introduce the Wet Gas Compressor, The WGC is the only small-frame electric direct drive reciprocating compressor that is capable of processing liquids – including liquid slugs – through itself. The WGC pictured is 30hp and has a 5 inch cylinder, with a maximum differential pressure of 200 psi and flow approximately 1.5x that of our CHC1050. Several power, flow and pressure configurations are available.

Standard Features

  • Highly efficient electric drive reciprocating compressor
  • Rates up to 360 mscf/d @ 30psi suction
  • Maximum ∆P up to 480psi
  • 150% more capacity than our largest HCG
  • 100% turndown capability
  • Easily processes liquids: slugs and entrained fluids
  • Ideally suited for casing gas and VRU applications
  • Optimized power utilization
  • No hydraulic system to maintain
  • Extremely robust intake and discharge valve design
  • Compression element can be serviced on site
  • No additional lifting equipment required for overhaul
  • Superior user interface – web browser HMI
  • All other features of HCG Compressor
  • Liquid handling capability – can process 100% liquids intermittently, at reduced capacity, and up to 5% of displacement at full speed
    • Capable of handling both steady entrained liquids and large slugs
  • Simple and reliable
    • Few moving parts
    • No pneumatic valves, separator or liquid pumps
    • Low speed, long stroke compression cycle
    • Low cost –easy to replace wear parts
    • Seals mounted in single piece seal cartridge for quick replacement
  • High shut in pressure rating – 1100 psi standard, 1500 (ANSI 600) optional – typically no ESD required
  • VFD speed control and auto start/stop
  • Easy and inexpensive to install and move
  • NACE (MRO175) materials standard
