).#2%!3%$ The COEN High Energy Electric Ignition (HEEI) system provides instan-taneous direct ignition for oil and
gas burners and
igniters. The COEN HEEI is integral to all COEN utility-grade
igniters to ensure consistent and reliable light-off of
igniter fuel. The COEN HEEI is also available as a stand-alone Class III Special
igniter assembly for direct ignition of liquid and gaseous fuels.The COEN HEEI consists of a high energy powerpack, spark cable, spark rod, and spark tip. Depending on the application, the HEEI sys-
tem also includes a retract assembly to retract the spark tip following ignition of the fuel.The system design consists of all solid-state components and uses low voltage DC to high voltage DC conversion for efficient and reli-
able operation. The high energy electric system utilizes a capacitive discharge design to provide a 12 joule per spark output. It delivers ten sparks per second, controlled by a patented timing circuit, which maintains a constant spark rate over the rated voltage range.
