Insulated PTC Air Heaters (HRP)

Insulated Air Heaters are finned resistor heaters with electrically insulated PTC heating elements, featuring higher resistance to humidity, dust and vibration. HRP (protected) can be designed for much higher voltages with protection class than other air heaters, which tremendously expands their field of application – from railway heating to HVAC systems. HRP will be available in three standard sizes with v-shaped or delta-shaped fins, and as custom solution on request.

  • Power output up to 3kW
  • Encapsulated heating elements
  • Covering rail with 4,5mm T-slot
  • Electrically insulated
  • Available with v-shaped or delta-shaped fins
  • Homogeneous load with three-phase connection
  • Thermally insulated housing allows for easy screw installation
  • Various installation options
  • Integrated temperature limiter
  • Special version for 110V, 460V, 900V
  • Railway industry version accord. to DIN 45545 (fire protection) and DIN50124-1 (insulation) on request
  • Custom solutions (size & shape, voltage, power output) on request
