Description
The CHR100 is a semiconductor PTC (Positive Temperature Coefficient) enclosure heater designed for efficient and self-regulating heating inside electrical control panels and industrial enclosures. It provides reliable anti-condensation, frost protection, and stable temperature maintenance for sensitive electrical and electronic components.
It is widely used in industrial automation panels, switchgear cabinets, telecom enclosures, outdoor control boxes, and harsh industrial environments where moisture control and thermal stability are critical for safe operation.
The PTC heating element automatically reduces power consumption as temperature rises, ensuring energy-efficient, safe, and maintenance-free operation without overheating risk.
