Mini PRS

Bison Compression has developed the Mini PRS; a low-to-medium capacity heated pressure reducing regulator for Natural Gas. This unit can be also thought of as an integrated “All-In-One” replacement for traditional two-stage Pressure Reducing Systems (PRS). It is a low-cost, extremely compact unit which significantly reduces pipework and connections to ensure trailered gas is made affordable to more customers. Bison has drawn on decades of experience to make the unit not only perform well but easy and cost-effective to service and maintain.

Outlet Connection                                                                   3/4” NPT x2

 

System Integration:

Install multiple units in parallel for increased flow requirements and/or redundancy. The small form-factor of the unit means pipework is still kept to a minimum

Standalone Systems: 

For a complete decanting system to take gas from trailer or mobile storage to deliver it to a low-pressure outlet, the Bison PRU systems integrate a decanting post with the PRA-010 regulator, control valves, pressure relief and basic system controls to create a small-footprint pressure-reducing system that will out-perform traditional systems. Bison has deliberately kept the system as simple as possible to ensure the overall system cost is kept to a minimum and to increase the reliability and ease of maintenance. A number of features are available to increase the effectiveness of the system depending on requirements.
Optional Features:

  • Automatic trailer swap-over
  • Automatic regulator fault-sensing
  • Pressure relief
  • Outlet Creep Protection System (prolongs regulator seat life)
  • On-site storage integration
  • Captured Venting
