Hobart 410840-00002 Fryer Hi-Limit Thermostat 1/4" X 4-1/2" Bulb 450°F 30" CAP

Built to provide high-temperature protection in commercial fryers, this hi-limit thermostat automatically interrupts power or gas flow when oil temperature exceeds 450°F (232°C). It uses a 1/4" x 4-1/2" sensing bulb placed inside the fryer tank to monitor oil temperature continuously. The signal is carried through a 30-inch capillary tube, enabling the control to respond quickly and shut down the system when unsafe temperature levels are reached. Maintaining a safe operating temperature is essential in fryer systems to prevent overheating and protect both equipment and operators. If the hi-limit thermostat becomes worn or fails to trip at the correct temperature, it can lead to unsafe conditions or equipment damage. Replacing it restores proper safety cutoff functionality and ensures reliable fryer operation. This component is commonly used in commercial kitchens where consistent temperature control and safety protection are critical during high-volume frying.
