Single-phase thermostat LF L3444070

A thermostat regulates the temperature inside catering appliances by switching the heating element on or off. In single-phase equipment, it monitors the current flow and adjusts the heat to maintain the set range. This ensures food is cooked, held or proofed at the correct temperature without manual intervention, freeing the operator to manage other tasks.

The operator sets the desired temperature on the thermostat dial or digital interface, depending on the appliance. Once the appliance is powered on, the thermostat continuously compares the internal temperature to the set point. When the temperature falls below the range, the thermostat closes the circuit, allowing current to flow and the element to heat. When the temperature rises above the set point, the circuit opens, cutting power to the element until the temperature drops again. This cycle repeats automatically, keeping the appliance within the selected range.

This LF single-phase thermostat is constructed for use in professional kitchens, where it must withstand frequent temperature changes and constant operation. It is designed to fit specific catering appliances, replacing worn or faulty units to restore precise temperature control.

The temperature range of 35 °C to 200 °C allows the thermostat to support a variety of cooking and holding processes. Lower settings are used for proofing dough or holding sauces, while higher settings enable frying, baking or boiling. The single-phase design means it is compatible with standard electrical supplies found in commercial kitchens, where three-phase power is not always available.

This thermostat is a direct replacement for parts numbered FOE.37, 5519232801, 5519234800, 1610145 and 375004, fitting equipment from the same manufacturer and other compatible models. It is listed in the catering equipment catalogue under temperature controls and spare parts.
