S-P thermostat LF L5037327

A safety thermostat cuts power when oil or water reaches a set temperature, preventing overheating in fryers and stoves. The LF S-P model monitors heat through a pen-shaped bulb immersed in the cooking medium, connected by a capillary tube to a switch inside the unit. When the bulb senses the limit, the thermostat opens the circuit, stopping the heat source until manually reset. This manual reset ensures the operator checks the appliance before restarting, reducing the risk of repeated overheating.

To use the thermostat, the bulb is installed into the fryer or stove's oil or water bath, with the capillary routed to the control housing. The unit is wired into the appliance's power circuit, typically in series with the heating element or gas valve. When the temperature reaches 299 °C, the thermostat trips, cutting power. The operator must press the reset button to restore operation, confirming the appliance is safe to run again.

The thermostat is built with a stainless steel sheath protecting the bulb, while the capillary tube measures 1490 mm to allow flexible placement. It features two single-phase contacts, designed for standard electrical circuits in professional kitchens. The pen-shaped bulb, 4 mm in diameter, fits into narrow thermowells or mounting points in fryers and stoves.

A temperature limit of 299 °C suits high-heat cooking processes like deep frying, where oil must reach and hold elevated temperatures without exceeding safe levels. The 1490 mm capillary length allows the control housing to be mounted away from the heat source, reducing exposure to splashes or steam. The two contacts provide a simple on-off switch for the appliance's heating circuit, compatible with single-phase power supplies.

Cleaning involves wiping the control housing and capillary with a damp cloth, avoiding immersion or high-pressure water. The bulb and sheath should be inspected for oil residue or damage, but no disassembly is required for routine upkeep.

This thermostat is a direct replacement for Angelo Po electric and gas fryers, as well as gas pot stoves, across multiple models listed in the manufacturer's catalogue. It is categorised under safety controls for professional catering equipment, ensuring compliance with kitchen safety standards.
