Highlights

Ultra-Portable. Quick to Deploy. Designed to be transported with a 1-ton truck and deployed with minimal site construction time. Trailer mounted skid reduces site preparation requirements, deployment, and set-up time.

Compact Design. The complete package is contained within a 15- foot (4.5 Metre) trailer for easy placement and reduced footprint requirements.

Maximum Trailer Offloading for Virtual Pipeline Efficiency. MobilePRS is designed to maximize offloading of trailer and storage tanks while maintaining desired outlet flow rates.

Consistent Gas Output During Trailer Switchover. Field tested Pressure Reduction Module (PRM) and Heat Control Module (HCM) deliver consistent gas flow throughout decanting cycle.

Increased Longevity in All Climates. Complete weather-proof enclosure means PRS unit will not be impacted by extreme weather. Serviceability will be maintained, operator safety and comfort ensured.

Simple, Controlled Performance and Efficiency. Simple and accessible controls ensure efficiency and performance can be optimized quickly with ease.

Regulatory Compliant. Currently compliant with NFPA 52/70 & ASME B31.3.

Essential Features

  • System mobility
  • Self-contained fuel-supply system
  • Trailer decant hose is the interface between CNG trailers and the PRS
  • User friendly touch/control screen for set-point and alarm control
  • Boiler utilizes natural gas from the tube trailer
  • Emergency Shutdown System (ESD)
  • Uses 2-stage regulation for maximum consistency of outlet pressure
  • Oversized components to retrieve maximum capacity from mobile storage units by allowing mobile storage to drain to lower pressure levels while maintaining rated flow through the PRS
