Diesel Genset to CNG or PNG Conversion is one time Cost for each type power production unit. However this can be adjusted in fuel cost saving. After the government banned on Diesel Generators it is now mandatory to convert each diesel generator to CNG with immediate effect. Dual Fuelling is simultaneous combustion of two fuels. Sanmish Dual Fuel solutions comprise of special kits that can be retrofitted on existing high speed diesel engines to allow use of a mixture of Methane rich gas (most often Natural gas) with Diesel as fuel. After conversion, the engine can continue to operate with only Diesel also. However, a Gas only operation is not possible.Converting your diesel generator to run on a Dual Fuel System (Diesel + CNG) is a cost-effective and future-ready solution, especially for industries seeking both economic and environmental performance.
Top Benefits of Diesel Generator CNG Conversion
Significant Fuel Cost Savings
Natural gas is 30–50% cheaper than diesel. After conversion, your genset can replace up to 60–70% of diesel with CNG, resulting in major monthly savings—especially for high-usage setups.
Reduced Emissions, Greener Operations
CNG burns cleaner than diesel. A converted generator emits lower CO₂, NOx, and particulate matter, helping your business meet pollution control norms and contribute to cleaner air.
No Need for New Equipment
Conversion doesn’t require you to replace your generator. The Dual Fuel Kit is installed on your existing diesel genset, which means lower capital investment and minimal downtime.
Flexible Fuel Use
If CNG isn’t available, your generator can continue running on 100% diesel. You get the benefit of dual fuel flexibility, ensuring power backup without fuel worries.
Quick ROI (Return on Investment)
Most users recover the cost of conversion within 6 to 12 months through fuel savings—making it one of the smartest energy upgrades available today.
Safe & Reliable Technology
Modern Dual Fuel Systems come with automated safety controls, leak detection, flame arrestors, and proper air-fuel ratio controllers, ensuring safe and efficient operations.
During Dual Fuel operation, a reduced quantity of diesel fuel acts as the ignition source for the air-gas mixture. The Methane rich gas mix replaces significant proportion of Diesel to produce equivalent heat energy during combustion in the cylinder. The emissions from such engines see an order of improvement. In the current market conditions this also means significant reduction in cost.
