CNG KIT



  • Dual (CNG and diesel) Kit
  • Full CNG Substitute Kit
  • Suitable for DI and CRDI Fuel,Injection Diesel Tractor, Pickup Vehical & Mini Trucks
  • Suitable from 35 to 75kw application

Benefits of CNG Refurbishment

  • Shifting to Economical fuel 25 to 30 INR less cost
  • Shifting to clean fuel less carbon emission
  • Contamination Free Fuel
  • Higher Efficiency
  • Mixing Ratio tuning to requirements 40% to 70%
  • Less Filter Replacement.
  • Over all 30% to 40% saving. Compared to diesel
  • Installation team can be deployed at sugar factory for bulk quantity

Safety & Approval

  • Reduced Vibration & Longer Oil Life
  • As per IS ..... standard
  • ARIA Approval for refurbishment Dual Fuel Kit

Hollow Fiber Membrane Technology for CO2 / CH4 Separation

  • The membrane separates gases by the principle of selective permeation across the membrane wall.
  • Input Raw Material Moisture : Max 55%
  • Relatively fast permeable gases such as CO2 and H2O to pass through the membran wall quickly are diverted.
  • The slow permeable gasses such as CH4 and N2 flows straight through are part of the product gas.
  • The medium is permeable gases such as O2 and H2S will be partially separated.
