Ex screw-in heaters up to 21 kW, type of protection Ex det, controller/limiter reset accessible from outside.
Our CSN® Ex screw-in heaters are designed for outputs of up to 21 kW and are ideal for heating liquid and gaseous media. These heaters are specially designed for use in potentially explosive environments and provide a reliable and efficient heat source. Thanks to their integrated temperature monitoring, they can precisely control the operating temperature and thus ensure a safe working environment.
