Applications

Designed for burners, boilers, kilns, and furnaces—any system utilizing bed-fired mechanisms or requiring igniters to retract due to extreme heat conditions. Ideal for industrial applications and power generation, our retracts are tailored for environments where rows of burners necessitate a precision-controlled ignition system. Please note that our retracts are not intended for turbine applications due to their controlled and manufacturer-specific nature. 

Details and Benefits

A pneumatic retract system typically includes an Igniter (commonly the 02 series igniter), Rod Adaptor, Harness, and Exciter. This is in addition to the actual Pneumatic Retract. Key parameters considered from the customer include insertion depth, solenoid rating requirements, solenoid power options, and mounting style options.

Pneumatic Retracts require a plant air supply and can be powered by (110-120 VAC, 60Hz), (220-240VAC, 50/60 Hz), or (24 VDC) electronic power supplies. Chentronics Pneumatic Retracts are available with stroke lengths of 8”, 12”, 20”, or 24”, offering flexibility to suit various applications.

Various end connections are available, including 4.25” OD Flange, “O” Flange Mount, 1” NPT Mount, Square Cut, D Flange, and 5.00” OD Flange. All configurations come with options for No Port, ½” Port, or ¼” Port, with the port designed for cooling air, particularly beneficial for high-temperature applications like kilns.

Chentronics Advantage

Chentronics’ Ignition Retracts offer a superior solution, allowing for enhanced preventative maintenance on the ignition system by safely retracting the igniter tip from the combustion chamber. When paired with the complete ignition package, including the retract from the ignition OEM, seamless integration is achieved. This ensures optimal tolerancing and compatibility, distinguishing our retracts from third-party machine shop alternatives that may lack the precision and seamless integration required for reliable performance in demanding environments.
