CleanPRS Advantages

Significantly Reduced Mobile Storage, Operation and Monitoring Costs

Reliable & Continuous Gas Supply. Automatically Maintained During Trailer Switch-Over

Efficient, Controllable & Reliable Outlet Temperature for Your Application

Highly Standardized Field-Tested Designs & Experience You Can Trust

Reliable & Continuous Gas Supply

Optimized and automated trailer switching ensures continuous gas supply during daughter station decanting process.

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.

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 cost by reducing a customer inventory of mobile storage units.

Simple, Cost-Effective 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.
