Ex flow heater with integrated, externally accessible temperature monitoring for outputs up to 21 kW.
Our CSN® Ex flow heaters are designed for outputs of up to 21 kW and are ideal for heating flowing liquid and gaseous media. These electric instantaneous water heaters are specially designed for use in potentially explosive environments and provide a reliable and efficient heat source. Thanks to their integrated temperature monitoring, you can precisely control the operating temperature and thus ensure a safe working environment.
