UNIVERSAL CAPILLARY THERMOSTAT RTKSA CAPILLARY SYSTEM – TÜV-TESTED
TECHNICAL DATA
APPLICATION
Colour:
anthracite grey (similar to RAL 7016), front side transparent
This series of devices was specially developed for use in heating technolo- gy; 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 sets are not included in the scope of delivery. The JZ-29 mounting set must be used in conjunction with immersion sleeves or protection coils. When used as contact controller (pipe mounting), mounting set JZ-31 must be used, except with models RTKSA-000 100 and RTKSA-001 100.
