CompletePRS Advantages

Reduced Operating Costs. Ensuring a Complete Offload Significantly Reduces Operating & Capital Expense

Reliable & Continuous Gas Supply. Gas Supply & Pressure is Maintained During Switch-over.

Maximum Offload Capacity Ensures Cost-Efficient Operation. Trailers Return as Empty as Possible.

Highly Standardized Designs Offers Simpler Ordering and Engineering

Highlights

Reduced Operating Costs. The proven design of the CompletePRS significantly reduces capital and operating costs. A combination of simple operation and monitoring, efficient heat management, and high peak capacity reduce mobile storage requirements delivering big savings.

Reliable & Continuous Gas Supply. Optimized and automated trailer switching ensures continuous gas supply during daughter station decanting process.

Maximum Offload Capacity. In conjunction with CleanCNG™ compressors, Clean Energy Compression’s Pressure Reduction Systems (PRS) maximize Offload Capacity, ensuring that only a minimal amount of gas is left on the trailer before it is disconnected. This is achieved by using two line unloading methodologies where possible, designing systems for minimal pressure drop, and employing scavenging compression where necessary to remove remaining gas.

Benefits

  • Standardized & Field-Tested Products. Quality standard design performs under a variety of conditions, based on Clean Energy Compression’s considerable experience in building PRS units for various markets.
  • Experience You Can Trust. From engineering, commissioning and ongoing field support, our team of experts ensure your projects’ long-term success.
  • Efficient, Reliable Outlet Pressure & Temperature for Your Application. Active heating system allows flexible and controllable heating supply while maintaining efficiency.
  • Reliable Pressure Regulation. First stage pneumatic control valves minimize the drop that occurs in much larger regulators and provides added protection in case of a regulator failure.
  • Significantly Reduced Mobile Storage Costs. Increased per-unit PRS capacity reduces capital costs by minimizing required inventory of mobile storage units
  • Simple Operation & Monitoring. Control screen provides user friendly display where operator can easily control and view system status and alarms. Remote monitoring to ensures speedy maintenance response.
  • Reduced Operation & Operator Labour Costs. Intelligent controls leading to improved operational efficiency and robustness
