Certified in accordance with the latest version of the standards DIN EN 50155, DIN EN 50121, and DIN EN 45545, JUMO panel-mounted thermostats from the EM type series have passed a test in which they completed 5.3 million switching processes without a single fault. In continuous operation, this result yields an operating life of up to 20 years. The temperature controller operates according to the liquid expansion principle: the filling liquid in the measuring system expands when warmed and thereby actuates a micro switch via a transmission mechanism. Due to an aluminum die-cast case bottom section and an impact-proof polycarbonate case top section JUMO AMTHF series surface-mounted thermostats are impervious to environmental influences. As a result, these thermostats can be used not only for air conditioning but also to regulate and monitor temperatures in oil transformers. ATH-SW series surface-mounted thermostats are particularly well suited for anti-freeze monitoring in service water, wastewater, and quench water tanks. These thermostats are also available in versions suited to mounting on DIN rails.
