Ex flow heaters (industry) for outputs up to 30 kW (AH) and 50 kW (AHA) and for heating flowing liquid and gaseous media.
Our CSN® industrial flow heaters (AH) offer compact solutions for outputs of up to 30 kW and are ideal for heating flowing liquid and gaseous media. For even higher requirements, our CSN® Ex instantaneous water heater (AHA) is available, offering outputs of up to 55 kW. Both models enable efficient heating in potentially explosive environments. The AHA series can alternatively be equipped with integrated temperature monitoring to ensure additional safety.
