Thermostat Tefcold SpareParts TC1022600059

A thermostat regulates the temperature inside a refrigeration unit by sensing the air or evaporator temperature and switching the compressor on or off. The K50-L3420 uses a capillary tube filled with a temperature-sensitive fluid that expands or contracts as the temperature changes. This movement activates a switch inside the thermostat body, maintaining the set temperature without manual intervention.

To install, the operator fits the thermostat body into its mounting bracket, connects the electrical terminals, and routes the 500 mm capillary tube to the sensing point inside the cabinet. The control knob or dial is then set to the desired temperature, and the unit is powered on. The thermostat continuously monitors conditions, cycling the compressor to keep the interior within the selected range.

The K50-L3420 is constructed with a durable housing and a 500 mm capillary tube, allowing flexible placement within the refrigeration unit. The length of the tube ensures it can reach the optimal sensing location, whether near the evaporator or inside the cabinet air stream.

This thermostat is a direct replacement part for compatible Tefcold refrigeration equipment, ensuring consistent performance in professional catering environments where precise temperature control is critical for food safety and storage.
