RTKSA-002.310

Universal capillary thermostat, 20…150…°C, hysteresis -10…-15K, TB, internal setting, external resetting

This series of devices has been specially developed for use in heating technology in boiler systems or storage tanks, district heating transfer stations and heat transfer systems, in ventilation technology as supply air monitors or as limiters of electric heating registers as well as for controlling and monitoring temperatures on pipes and tanks. Immersion sleeves, protective coils, and fixing sets are not included in the scope of delivery. The JZ-29 fixing set must be used in conjunction with immersion sleeves or protection coils. When used as a pipe-mounted controller, the JZ-31 fixing set must be used.
