Innovation For Cold Starts – Nozzle Line Assembly Heater
When temperatures drop, performance matters more than ever. That’s why SunFire continues to innovate, delivering reliable heat when and where it’s needed most.
Our latest enhancement, the Nozzle Line Assembly Heater using our Frigid Quickfire technology is designed to take cold-weather performance to the next level by eliminating common startup issues and ensuring consistent operation, even in the harshest environments.
Why Cold Weather Creates Challenges
In extreme conditions, diesel fuel can begin to thicken or gel, restricting proper flow through the system. This can lead to:
- Difficult startups
- Inconsistent flame performance
- Increased wear on critical components
These issues don’t just impact performance, they can also result in unnecessary downtime and increased maintenance.
The Solution: Nozzle Line Assembly Heater
SunFire heaters now feature an integrated nozzle line heater within the burner assembly, engineered specifically to combat fuel coagulation, our Frigid Quickfire technology. This system warms the fuel as it passes through the nozzle line, helping maintain the proper viscosity.
The result is reliable ignition and smooth, consistent operation, even in freezing temperatures.
The Nozzle Line Assembly Heater kit comes standard on all models including the SF80, SF120, and SF160 on all models from 2026 and beyond.
