The LHS 21L CLASSIC was developed for special integration directly in production and machine systems for sterilizing, drying, welding, cleaning, shrinking, shaping, hardening, trimming and activation activities. With its compact housing and easy installation from above, the industrial air heater can be integrated quickly and easy in all types of production lines. With an output of 3.3 kW and a high maximum temperature, the unit is thus a universally applicable powerhouse.
The LHS 21L CLASSIC shines in numerous applications: For example, it is perfect for various drying and heating processes, shrinking and welding packaging sheets and plastic molded parts, as well as sterilizing packaging materials like bottles, corks and containers. At the same time, safe and reliable operation is guaranteed thanks to Leister’s tested and proven quality, as well as the device and heating element overheating detection.
