Reliable-CNG-Maintenance-300x299

Highly Standardized Designs Offer Simpler Ordering and Engineering

Standardized, Modular & Scalable. Streamlined modular engineering improves initial specification, speeds up delivery time, and reduces prices on standard equipment.

Cleaner Fuel with Less Oil Contamination. Non-lubricated compressors produce clean CNG with no oil contamination which reduces fleet maintenance, cost of operation, and extends vehicle engine life.

Redundancy & Reliability. Compressors’ modular design allows additional compressors to run in series for mission-critical redundancy and flexibility.

Serviceability:

  • Service pathway for easy access
  • Multiple access panels
  • Standardized service connection panel
  • Slide-out heat exchangers for easy access and inspection
  • Access key service items directly from service doors
  • Direct access to grouped pressure relief valves
  • Complete compressor access via swing-away inlet louvers
  • Lockout valves on recovery tank and PSV for easy, vent free servicing

Low Vibration & Noise

  • The CleanCNG™ offers less than 75 dBA @ 3m –  revolutionary in the CNG industry
  • Vibration measurements meet or exceed API 618 and recommended industry guidelines

Actuation Options

  • Option for Gas or Air actuated valves

Low Oil Carryover

  • Non-lubricated compressors produce high-quality CNG through the use of self-lubricating piston rings and rod packings
  • Clean Energy Compression boasts lowest levels of oil carry over amongst major CNG compressor suppliers: 5ppm or less
  • The CleanCNG™ produces the cleanest downstream gas, avoiding oil build-up and ensuring cleaner combustion at the vehicle

Essential Features

  • Non-lubricated cylinders, pistons, and valves for clean discharge gas (5ppm or less oil carryover)
  • Balanced reciprocating design for low vibration and low noise
  • Compressor layout designed for easy service
  • Electrical control (PLC/MCC panel with alarm status indicators for unattended operation)
  • Self-lubricating Teflon and/or PEEK composite piston rings and rod packings
  • High efficiency gas-to-air heat exchanger for inter-stage and discharge gas cooling

Specification Details

  • Measurements dependent on environmental conditions.
  • Vertical air discharge louvre.
  • Sound measurement results are considered approximate and specific to the Clean Energy Compression factory measurement location as they may vary due to acoustic variables at the final installation site.
  • Clean Energy Compression is not responsible for sound measurement results at the installation site. Any specific sound abatement requirements are the responsibility of the client.
  • Metric conversions given for reference only.
  • Gauge pressure at 0m elevation (1.01325 Bar). At 70°F Inlet Gas, 80°F ambient gas temperature conditions.
  • Not all codes will be applicable for all projects. Please contact Clean Energy Compression for additional details on design codes.

A global leader in manufacturing CNG and LNG fueling systems, Clean Energy Compression meets or exceeds standards for ISO 9001:2008 Quality Management System as well as extensive safety and environmental protocols. Our partners applaud our dedication to safety.

Safety

  • The compressor enclosure is rated as a Class 1, Div. 2, with gas detection, ventilation and lighting
  • Exterior Motor Control Center (MCC) area rated as non-hazardous
  • Signal lights on operation panel to indicate compressor status and alarm state in event of gas leaks or Emergency Shut Down (ESD) alarm activation
  • MCC connections available for site fire detection cameras and communication hardware
  • Can be equipped for phone page or e-mail warning. Alarm will be sent in the event of emergency
  • ESD at each end of the enclosure, on the MCC, and one inside the enclosure.This cuts off gas supply, isolates storage, and drains compressors.
  • Overpressure protection with appropriately certified pressure relief valves.

Environmental

  • Non-lubricated compressors cut out the waste, cost, and negative environmental issues of additional filters, auto oil drain systems and supplementary oil tanks. Only 5 parts-per-million or less vs. 100 PPM or more.
  • Our clean technology prevents costly, troublesome oil accumulation in heat exchangers, storage vessels, and vehicle systems. This ensures lower operating costs, more effective fleet and vehicle performance, happier customers, and increased station profitability.
