Air heater incl. hot air recirculation

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, the LHS 410 DF-R HT recycles inlet air up to a maximum temperature of 350° C. The double flange design allows the Leister tubular air heater to be easily installed in piping systems.

  • Maximum 900 °C Air outlet temperature 
  • Hot air recycling saves money and energy 
  • Suitable for integration into piping systems

The LHS 410 DF-R HT is equipped with ceramic insulation between the air heater and the connection housing. The ceramic insulation ensures that the electrical connections of the tubular air heater are protected against overheating caused by hot air flowing back. The double flange air heater is used in various industrial processes and applications. For example, in the packaging industry in shrink ovens, in the automotive industry for preheating cable harnesses, in the metal industry for relieving stresses in the material, to name just a few. In the metal and plastics industry, the LHS 410 DF-R HT is often used in applications where hot air recirculation is required.
