4058 Retractable high energy igniter "HEI" system
RETRACTION ASSEMBLY CONFIGURATION OPTIONS
The 4058 is a retractable high energy spark ignition system for lighting large capacity burners. It can replace a gas pilot because it puts a high intensity spark at an effective lighting location, and then retracts it to a thermally protected area. Retracting the igniter once the burner is lit greatly increases the igniter’s life.
The 4058 is configurable for many burner applications. The cylinder stroke, voltage, and area classification can be specified. Optional position switches (one or two) are available to indicate the cylinder position. For general purpose conditions, order as 24 VDC, 120 or 240 VAC to operate the solenoid and proximity switches. For classified area (either Class 1 Div.2 or ATEX) order with 24 VDC operation for the solenoid and proximity switches. The retraction mechanism is operated with compressed air via an integrated solenoid, and features an inline design with a hollow cylinder rod that allows for use in high backpressure applica- tions up to 15 psi (103 kPa). This design allows the assembly to be more compact and simplifies the mounting of the retraction mechanism on the burner. SMARTSPARK™ CONFIGURATION OPTIONS The standard 4058 igniter module to light natural gas or light oil burners is the SmartSpark™. It features solid state electronics in a 304-stainless steel exciter box and Inconel igniter tip which is mounted directly on the retraction assembly. It also has a pre- fault LED diagnostic indicator for igniter tip wear.

It can be configured with different length extension rods, and has options for classified areas (either Class 1 Div.2 or ATEX).
The 4058 has a number of modules that can be configured to fit many applications. They can be ordered as a complete assembly or ordered separately.
Custom engineered high energy igniters are also available for special fuel gases and heavy oils or where environmental conditions may require special material use. Consult your North American sales and application engineer for your specific needs.
