Applications: Protection against the overheating of the heaters due to an abnormal rise of the liquid temperaturedue to a flow failure. The mounting of the bulbs can be made inside standard dia. 8.5mm pockets, or in an additionalthermowell added on request.
Through wall fittings on capillary are also available. The thermostat body can be installed in a protective cover of theheating elements outputs, or remotely in a separate control cabinet. They are resettable after tripping, but prior fullaudit of the circuit is essential to find the cause of overheating and correct it before restarting.
