UnpluggedCNG Advantages

Reduced Electrical Power Requirement. Save Money, Improve Reliability.

modular2

Proven Technology. CleanCNG™ Compressor and Gas Drive Engine.

Cleaner Fuel. Non-Lubricated Compression Reduces Oil Contamination in Fuel by 95%, Lowering Compressor & Vehicle Maintenance.

Ultra-High Reliability with Advanced Remote Monitoring Capabilities.

Highlights

Reduced Electrical Power Requirement Means Cost Savings and Uptime. Natural gas powered combustion engine generates the required power for compression dramatically reducing electrical power cost and dependency on the power grid.

Ultra-High Reliability.  Proven platform combined with advanced remote monitoring options ensures the gas keeps flowing.

Proven Technology. The UnpluggedCNG builds on 25 years of engineering leadership in non-lubricated compressors using the proven CleanCNG™ ‘W’ Compressor Block combined with the world’s most popular natural gas combustion engines in 200 or 300 hp capacities.

Benefits

Low Oil Carryover. Non-lubricated cylinders, pistons, and valves means fewer oil changes and reduced oil damage to vehicles or virtual pipeline infrastructure.

Reduced on-site maintenance costs and downtime. Peace of mind with proactive remote monitoring means fewer service emergencies and critical downtime.

Reduced Servicing Costs. Optimized compressor bay layout is designed specifically to cut installation times down on most common standard maintenance procedures.

Low-Cost Site Preparation Requirements & Commissioning Time. Several factors including less vibration and noise, heat planning and modular architecture contribute to significant efficiencies in compressor placement and required site preparation.

More Gas, Less Energy. Less cost-per-cubic-foot pumped. Improved cooling design and new ultra-high efficiency cooling reduce energy requirements per unit produced.

Simplified Engineering. Standardized units are pre-engineered to meet demands of vast majority of global markets and requirements with no additional engineering.

Clean. Lower fugitive emissions due to air actuation of control valves.

  • Environmental dependencies
  • 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, 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 Class 1, Div. 2, with gas detection and ventilation.
  • Exterior Motor Control Center (MCC) area rated as non-hazardous.
  • Enclosure equipped with gas detection and Class 1, Div. 2 lighting.
  • Signal lights on operation panel to indicate compressor status and alarm state in event of gas leaks or Emergency Shutdown Device (ESD) alarm activation.
  • MCC connections available for site fire detection cameras and communication hardware.
  • Can be equipped for phone, pager, or email warning, or an alarm will be sent in the event of an emergency.
  • ESD (Emergency Shutdown Device) 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.
  • Further details available upon request.

 

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; ensuring lower operating costs, happier customers, and increased station profitability.
