RAK: Universal thermostat
How energy efficiency is improved
Demand-led controlling, monitoring and limiting, without auxiliary energy.
Areas of application
For controlling and monitoring the temperature of liquids in baths, tanks, pipelines and ducts. Thanks to
modular design, can be used as controller, monitor, limiter or safety limiter.
