LHS 21S

• Patented heating element protection
• Device overheating protection
• Fully integrated control electronics
• Cost-effective
• Integration in existing control system

The LHS 21S SYSTEM air heater features integrated power electronics, enabling continuously variable air temperature adjustment, which renders external power control (e.g. semiconductor relay) unnecessary. Regulation via a remote control is also an option with an electroplated separate 4 – 20 mA interface as a controller, PLC (Programmable Logic Controller) or external potentiometer. The integrated device and heating element cover offers reliable protection against damage to the air heater from excessively high temperatures.
