Industrial Hot Air Devices

Leister hot air tools are used in countless industrial production processes. In fact, there are very few industries that do not benefit from our versatile offerings, regardless if the process only operates with hot air or if it becomes more efficient with hot air. Leister has the right blower for every production line.

Details

Experience And Quality Combined

The LHS 41S SYSTEM covers a broader spectrum of applications with its numerous analog and digital additional features compared to CLASSIC and PREMIUM products. The compact design and ability to attach a powerful external blower via air hose connection makes the air heater a perfect product for demanding production processes. The 50 mm (1.97 in) heating tube diameter also permits a particularly strong air flow, which allows more area to be processed simultaneously.

Leister’s decades of experience in processing plastics led to the development of sophisticated heating element designs and patented heating element covers. These guarantee a high degree of accuracy, reliability and quality for our customers. The LHS SYSTEM air heaters enable easy to control operations through an integrated temperature probe, integrated controller and digital display with current and target temperature values. The integrated power electronics make external power controls a thing of the past while simplifying the wiring in the process.

Highlights

Hot Air Precision

PRECISE
Digital display for precise control
The LED display shows target and current temperature values both in degrees as well as percent,
and thereby facilitates precise control and reproducible results.

CONNECTION-READY
Analog interface with 4 – 20 mA signal or 0 – 10 V
The standard interface facilitates integration into an existing control system such as controller,
PLC (programmable control system) or external potentiometer.

EASY INSTALLATION
Optimized Product Design
The small footprint of the housing and the attached mounting plates facilitate
easy integration into the production process for system designers and production managers.
