PTC Heater

HG 140 | 15 – 150 WPTC Heater HG

These PTC Heaters are used in enclosures where damage from condensation must be prevented, or where the temperature must be maintained above a minimum value. The aluminum profile heater body design has a chimney effect to distribute heat evenly. The cage clamp connectors save time and simplify installation.

Positive temperature coefficient heaters offer significant benefits in heating, they are self limiting, which means that the heating power adjusts to the ambient temperature.
