Honeywell Kromschroder 84391055 Ignition Transformer

Description

The Honeywell Kromschröder 84391055 Ignition Transformer TGI 7,5-12/100R is an enclosed high-voltage ignition transformer designed to generate a reliable ignition spark for industrial gas burners and gas-ignited or directly ignited oil burners. It provides a 7.5 kV ignition voltage with a 12 mA output current, operates on 115 VAC, and is rated for 100% continuous duty, making it suitable for demanding combustion control applications. Commonly installed on industrial burners, boilers, furnaces, ovens, thermal processing equipment, and combustion management systems. Maintenance teams and combustion engineers use this transformer for OEM replacement, burner repair, retrofit projects, and ignition system maintenance. 

Applications

The Honeywell Kromschröder 84391055 is used to provide high-voltage spark ignition for industrial combustion equipment operating on natural gas, propane, or gas-fired oil systems. Its enclosed IP65 housing allows installation close to the burner in harsh industrial environments, while its continuous-duty design makes it suitable for boilers, process heaters, industrial furnaces, kilns, drying systems, and commercial combustion equipment. The transformer also supports single-electrode ignition and flame monitoring when used with compatible burner control units.
