Single-phase thermostat LF L5111899

A thermostat controls the temperature of the oil in a commercial fryer, ensuring it remains at the level needed for consistent frying. The heating element in the fryer draws power until the oil reaches the set point; once that temperature is reached, the thermostat cuts the power to prevent overheating. When the oil cools below the set point, the thermostat reconnects the power, maintaining a steady cycle. This regulation prevents food from absorbing excess oil, keeps the crust crisp and the interior properly cooked, and extends the life of the oil by avoiding breakdown from excessive heat.

The WQS-230 single-phase thermostat is installed inside the fryer's control housing, where it connects to the heating circuit. The operator sets the desired temperature on the dial, typically marked in degrees Celsius. Once the fryer is switched on, the thermostat continuously monitors the oil temperature through its sensor, opening and closing the circuit as needed. The operator loads the fryer basket with food, lowers it into the oil, and removes it when the cooking time is complete, relying on the thermostat to keep the oil at the correct temperature throughout.

This thermostat is designed for single-phase electrical supply, matching the standard circuit found in most professional kitchens. Its construction includes a temperature-sensitive element that responds to changes in the oil, and a mechanical switch that interrupts or restores the current. The dial and sensor are housed in a durable casing, protecting the internal components from the heat and moisture of the kitchen environment.

The WQS-230 thermostat is compatible with a range of professional fryers from HORECA SELECT, MAKRO-PROFESSIONAL, MCC TRADING INTERNATIONAL, and METRO AG. It fits specific models including the HORECA SELECT GDF1104, GDF1108, GDF2124, and GDF2128; the MAKRO-PROFESSIONAL GDF3004, GDF3008, GDF3024, GDF3028, GDF5008, and GDF5028; the MCC TRADING INTERNATIONAL HDF1104, HDF1108, and HDF2128; and the METRO AG GDF3004, GDF3008, GDF3024, GDF3028, GDF5008, and GDF5028.

Regular inspection of the thermostat ensures it remains free of oil residue and debris, which can affect its accuracy. The sensor and casing should be checked for signs of wear or corrosion, and the dial should move smoothly without sticking. If the fryer fails to maintain temperature or overheats, the thermostat may need replacement to restore proper operation.
