Universal capillary double thermostat RTKSA

Application

This series of devices was specially developed for use in heating technology; in boiler systems or storage tanks; district heating transfer stations and heat transfer systems; in ventilation technology to monitor supply air or as limiters for electrical heating coils, as well as for controlling and monitoring temperatures in pipelines and tanks.

Immersion sleeves, protection coils and mounting set JZ-31 for pipe mounting are not included in the scope of delivery.

Accessory JZ-30 must be used in conjunction with immersion sleeves.
