Flow Heaters

The Kanthal® Flow Heater delivers the highest outlet temperature on the market -- up to 1100°C (2012°F), temperature accuracy within ±1°C and net efficiency of up to 95%. The full range is available with 3.5 kW, 11 kW, 20 kW, 30 kW, 40 kW, and now 60 kW. In addition, we offer customized models for individual processes and demands.


With a unique design and robust internal temperature control, the Kanthal® Flow Heater can deliver gas outlet temperatures of up to 1100°C (2012°F), compared with 800°C (1470°F) in conventional air heaters, as well as a temperature accuracy within ±1°C. When it comes to drying and preheating processes, flow heaters can deliver the same performance as gas burners but with increased heat efficiency. They can also reduce the CO2 footprint and eliminate combustion-related pollutants such as NOx and SOx from processes or facilities.
