High reliability Pilots are the foundation of a safe and reliable fired appliance. Unifire Pilots incorporate our proprietary HEI technology to deliver continued reliability and performance.





Our standard 100,000 BTU/Hr pilot has been keeping 100’s of burners lit for the past 8 years. This platform has been customized and extended to a myriad of process heating applications and continues to evolve as the alternative to leading burner vendors natural gas pilots.

For higher heat release applications we have a staged forced draft pilot that exhibits the same stabilty as our pre-mix models but provides to 1.5MBTU/hr heat release.

Ignition is provided by the integrated eHEnergizer.  All pilots are configured to integrate with the leading vendor UV flame safeguard technology and will ship direct for field install ready to fire. Installation is as simple as hooking up to the field regulated gas supply and a controlling BMS PLC.
