Small Semiconductor Heater
HGK 047 | 10W to 30W

  • Dynamic heating up
  • Energy saving
  • Wide voltage range
  • Clip fixing

The heaters are used in enclosures where condensation is to be prevented or the temperature may not fall below a minimum value. In this way corrosion is avoided and an even temperature is ensured. The heaters are designed for permanent operation.
