Addressing Enterprise Procurement Demands: Total Cost of Ownership (TCO)
B2B EPC contractors, utility companies, and corporate operations face razor-thin margins and strict carbon benchmarks. Selecting a multi-fuel system delivers three critical balance-sheet benefits:
Amortized Operational Arbitrage
By leveraging locally accessible pipeline natural gas or flare gas over expensive delivered diesel, commercial operators achieve CAPEX recovery on dual-fuel control retrofits and prime sets within 6 to 14 months of continuous running.
Supply Chain Continuity Insurance
In regions facing diesel allocation rationing, logistical blockades, or extreme weather delays, multi-fuel capabilities allow instantaneous redirection to LPG tanks or LNG bowsers, eliminating catastrophic production plant blackouts.
ESG & Carbon Compliance
Gaseous substitution significantly curtails nitrous oxide (NOx), unburned hydrocarbons, and black carbon particulate emissions, enabling compliance with strict municipal environmental permits and corporate ESG decarbonization quotas.
Localized Engineering Support & Global Regulatory Harmonization
A generator is only as reliable as its regulatory compliance and emergency field maintenance support. We ensure every unit is ready for seamless grid synchronisation and jurisdictional inspection.

Frequently Asked Questions: Technical Procurement & Integration
Authoritative insights addressing critical engineering, fuel management, and warranty queries from international project buyers.
What is the substitution ratio of gaseous fuel in dual-fuel operation?
Depending on load stability and engine displacement, modern ECU injection can achieve a 70% to 80% natural gas substitution rate under typical 70-80% prime load conditions. A minimum 20% diesel pilot injection is typically maintained to provide compression ignition and lubricate internal injectors.
How does the system react if the external gas supply line drops pressure?
The electronic gas control valve is linked with pressure transducers. If gas supply pressures drop below calibrated limits (e.g., <1.5 psi / 10 kPa), the controller executes an instant transition to 100% diesel fuel mode in under 10 milliseconds without load fluctuation or engine shutdown.
What is the standard warranty coverage and parts availability?
Every generator set comes standard with a comprehensive 12-month warranty counted from the initial start-up date. We support complete spare parts availability through long-standing Perkins supply channels, dispatching critical maintenance components within 24 hours.
How do you convert kW to kVA accurately for sizing multi-fuel equipment?
Real electrical power in kilowatts (kW) is divided by the power factor (standard 0.8 for commercial 3-phase systems). For example: 200 kW ÷ 0.8 = 250 kVA. Sizing must also account for electric motor inrush startup currents and site derating factors such as high altitude or high ambient temperatures.
Can flare gas or raw wellhead gas be utilized directly?
Yes, provided the gas undergoes conditioning. Flare gas containing H2S, excess moisture, or heavy hydrocarbons requires filtration and knock-out pots to avoid injector fouling, cylinder acid etching, or engine detonation.
What are the maintenance differences between multi-fuel and diesel gensets?
Multi-fuel systems burning clean natural gas often enjoy extended lube oil lifespans and reduced carbon buildup across cylinder heads and valves. However, routine inspection of the gas train, solenoid cut-off valves, and fuel rail pressure sensors is required during 250-hour service intervals.
