• Retract monitors pressure and flow for camera lens cooling. Pulls camera out of high heat if levels fall below preset values
• Operator override allows manual retraction for inspection and cleaning
• Multiple retraction lengths allow complete removal from boiler, kiln or furnace
• Remote control/monitoring versions available
• Universal power supply
• Temperature controller option


The IST-Quadtek® high temperature imaging camera systems are cooled by air or water. If the plant supply of air pressure, water or electricity is interrupted the M356 Pneumatic Automatic Retract System will retract the camera from the most severe heat, protecting it from serious damage. With the camera retracted from the intense heat the operator has time to arrive at the location and manually pull the lens clear of the viewport. Then they can track the coolant problem and re-install the camera. The M356 system works with the IST-Quadtek Bedbug®, Lynx® and Spyrometer® cameras, as well as cameras of many other manufacturers.

The M356 retraction system now includes a ruggedized safety air reservoir and additional options such as locking pistons for downward-inclined camera installations.
