  • Easy to integrate (mounted from above)
  • Overheat detection with alarm output for the heating element
  • Tool overheat detection with alarm output

These advanced air heaters are distinguished by their extremely small dimensions—especially the lean design (only 67 mm / 2.6 in wide)—as well as their long service life. Designed for professional integration into machine systems, the new LHS series enables any specific application. Sterilizing, drying, welding, cleaning, shrinking, shaping, deburring and activating are now more efficient and reliable thanks to Leister’s proven hot-air technology!
