Features & Benefits
• Reliable & Continuous Gas Supply. Optimized &
automated trailer switching ensures continuous gas
supply during daughter station decanting process
• Standardized & Field-Tested Products. CEC’s
considerable experience in building PRS units for
various markets has resulted in a quality standard
designed to perform under a variety of conditions
• Experience You Can Trust. From engineering,
commissioning and in the field, you will get the
support you need
• Efficient & Reliable Outlet Pressure & Temperature for
Your Application. Active heating system allows flexible
and controllable heating supply while maintaining
efficiency
• Ultra-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 inventor y 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 ensure speedy maintenance
response
• Reduced Operation & Operator Labour Costs.
Intelligent controls leading to improved operational
efficiency and robustness
• Heating system optimized to accommodate optimal
pressure & flow transitions
• User friendly touch-screen HMI 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
• Optimized system resistance to maximize usable gas
from tube trailers
• Efficient heat management means less power
consumption per cubic meter/foot
