These advanced air heaters are distinguished by their extremely small dimensions – especially the lean design (only 2.64 inches 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!
