Chicago Dryer Hi-Limit Thermostat – 4206-500

The 4206-500 Hi Limit Thermostat is a temperature safety control used in Chicago Dryer Company flatwork ironer systems. This component functions as an over-temperature protection device, interrupting the heating circuit if chest or roll temperature exceeds the preset safety threshold. The hi limit prevents overheating conditions that can damage padding, belts, heating elements, or finished goods.

The hi limit thermostat is typically mounted in the heated chest assembly or thermal control circuit. Proper operation is critical for maintaining safe operating temperatures and protecting both equipment and operators in commercial laundry environments.

Maintenance Tip: Always verify reset condition and temperature rating before replacing a hi limit to ensure it matches the original trip specification.
