Cummins diesel fuel generators leverage the strength of diesel fuel while also benefiting from the extended availability of natural gas. These generators are engineered to comply with NEC and NFPA regulations concerning on-site fuel storage, ensuring safety and reliability in various scenarios. During emergencies such as severe weather or disruptions in natural gas supply, these generators offer a robust solution by seamlessly transitioning to diesel fuel operation. This flexibility ensures continuous power supply, making Cummins diesel fuel generators a dependable choice for critical applications requiring uninterrupted energy.

A critical parameter for dual fuel operation is the substitution rate – the portion of total fuel energy provided by natural gas. A maximum substitution rate of 70 percent can be achieved with Cummins Dual Fuel for applications with high load factors. 

Cummins Endorsement of Dual Fuel for their engines

Cummins diesel fuel generators are designed to combine the reliability of diesel fuel with the flexibility of utilizing natural gas when available. Here’s a breakdown of their features and benefits:

1. Strength of Diesel Fuel: Cummins generators primarily operate on diesel fuel, which is known for its energy density and stability. Diesel fuel provides a consistent source of power, making it ideal for continuous and standby applications where reliability is paramount.
2. Flexibility with Natural Gas: These generators are equipped to integrate natural gas as an alternative fuel source. During times when natural gas is accessible and economically advantageous, the generator can seamlessly switch to natural gas operation. This dual-fuel capability optimizes operational efficiency and can lead to cost savings, especially during extended periods of use.
3. Compliance with Regulations: Cummins generators are engineered to meet stringent regulations set by the National Electrical Code (NEC) and the National Fire Protection Association (NFPA) regarding on-site fuel storage and safety. This ensures that installations comply with local codes and provide a safe environment for both operation and maintenance.
4. Emergency Preparedness: In scenarios such as severe weather events or disruptions in natural gas supply, Cummins generators can reliably switch to diesel fuel operation without interruption. This capability ensures continuous power supply, critical for applications where downtime is not an option, such as hospitals, data centers, and industrial facilities.
5. Dependable Performance: Cummins diesel fuel generators are renowned for their durability, efficiency, and low maintenance requirements. They are designed to deliver consistent performance under varying load conditions, maintaining stability and reliability over extended operational periods.

Overall, Cummins diesel fuel generators offer a robust solution for applications requiring dependable and continuous power supply. Their ability to integrate natural gas as an alternative fuel source enhances operational flexibility and cost-effectiveness, while their compliance with safety regulations ensures reliability in diverse operational environments.
