With up to 40 kW, the LHS 91 SYSTEM is a high-performance air heater from Leister and a true hot air power package. It is used where large air volumes and high temperatures are required in continuous operation. With this output, the LHS 91 SYSTEM is able to replace gas heaters, thus increasing work safety and environmental friendliness. In addition, the LHS 91 SYSTEM can be individually adjusted to the respective requirements in industrial hot air systems, such as overlap nozzles, tubes and round nozzles, flange connections and extension tubes.

Highlights
For demanding industrial processes
Robust
Durable heating element and exterior
Immense stress, high temperatures or demanding materials do not matter to the LHS 91 SYSTEM. It works reliably, thanks to innovative electronics as well as a dirt and stress-resistant housing made of cast aluminum.
Strong
Heating power source with peak performance
With up to 40kW performance, the LHS 91 SYSTEM is unbeatable in the processing of plastic, synthetic tissues, thin sheets, adhesives and other industrial methods in which process heat is required.
User-friendly
Easy to operate, thanks to the potentiometer and interface
With the LHS 91 in the SYSTEM version, the heating output adjustment can be continuously variable via the potentiometer and a control connection with the interface.
