Semiconductor Fan Heater
CR 027 | up to 650W

  • Compact heater
  • Integrated thermostat
  • Clip fixing
  • Optical indicator
  • Temperature safety cut-out

Semiconductor fan heater prevents formation of condensation and frost and provides an evenly distributed interior air temperature in enclosures with electric/electronic components. The integrated thermostat is used to set the desired temperature.
