The LHS 410 DF-R HT tubular air heater is a medium sized double flange high temperature air heater from Leister that can recirculate hot air. It offers an even higher air volume than the LHS 210 DF-R HT tubular air heater. With a maximum air outlet temperature of 900 °C/1652 °F, the LHS 410 DF-R HT recycles inlet air up to a maximum temperature of 350° C/662 °F. The double flange design allows the Leister tubular air heater to be easily installed in piping systems.
