Description
The Civaux CHR25 enclosure heater is a compact heating device designed to help protect electrical and electronic equipment from condensation inside control cabinets and industrial enclosures. It uses a positive temperature coefficient (PTC) heating element that regulates its heating behaviour as the temperature changes.
Condensation inside an electrical enclosure can contribute to corrosion, insulation problems, and equipment faults. Installing a suitable enclosure heater helps maintain a more stable internal environment, particularly in applications exposed to temperature changes or high humidity.
