Single-phase thermostat LF L3444633

A thermostat regulates the temperature of oil or water in commercial fryers, griddles and heaters by cycling power to the heating element. When the sensor detects the liquid has fallen below the set point, it closes the circuit and the element heats the medium. Once the target temperature is reached, the circuit opens and heating stops. This on-off cycle keeps the temperature steady within a narrow band, ensuring food cooks evenly and oil does not overheat.

The operator fits the thermostat into the appliance's control housing, connects the two power wires and the capillary sensor, then sets the desired temperature on the dial. The appliance is switched on and the thermostat automatically maintains the chosen temperature until the appliance is turned off or the setting is changed.

The unit is housed in a sealed metal canister that protects the internal switch and capillary from moisture and grease. The temperature dial is calibrated in degrees Celsius from 50 to 205, allowing precise control for frying, simmering or holding.

The temperature range of 50 °C to 205 °C covers the full span needed for professional frying, from gentle warming to deep-fat frying. The single-phase design matches the electrical supply used by most counter-top and floor-standing catering equipment in the UK.

Cleaning is limited to wiping the exterior of the canister with a damp cloth; the sealed construction prevents internal contamination. The capillary sensor should be checked periodically for kinks or damage that could affect accuracy.

This thermostat is a direct replacement for part numbers 5513042310 (DOSILET, MOVILFRIT, REPAGAS) and 5613042001 (EGO).

In the LF catalogue it is listed under Control Components for Fryers and Heaters.
