• Integrate into existing control system

The LHS 21S SYSTEM air heater has integrated power electronics with which the air temperature can be infinitely adjusted and which makes external power control (e.g. semiconductor relays) superfluous. In addition, remote control is possible through a galvanically isolated 4 – 20 mA interface for controllers, PLC (programmable logic control system) or external potentiometers. The built-in active device and heating element protection reliably prevents damage to the air heater due to excessively high temperatures.
