Customizable Two-Stage Rotary Vane Compressor System

CVR-2 Series

The TESCORP “CVR-2” SERIES is a completely self-contained two-stage compression system for applications for stock tank vapor recovery, flare gas recovery, or medium-pressure process gas application. Constructed with a rugged rotary vane compressor and TESCORP vapor recovery technology and components, the CVR-2 is a complete and fully-automated system for applications that require gas cooling, proportional capacity control, and sophisticated PLC driven control logic and communications.

The unit offers the following design and optional features:

Two-stage rotary vane compressor with:

  • Liquid-cooled for continuous duty
  • Oil-lubricated compressor
  • Mechanical seal
  • Special vapor recovery heads for saturated gas applications

Force feed lubrication system complete with:

  • Progressive flow type divider block lubricator, manifold, filter, and oil storage reservoir
  • Oil flow indicators, flow monitor, and controls
