PTC Panel Heaters
Product Overview
PTC Panel Heaters are designed to prevent condensation and maintain a minimum temperature inside electrical enclosures, control panels, and switchgear cabinets. The extruded aluminum profile creates a chimney effect for efficient and uniform heat distribution. The PTC heating element automatically limits temperature, ensuring safe and energy-efficient operation.
Key Features
- PTC self-regulating heating technology
- Wide operating voltage range (120–240V AC/DC)
- Fast heating response
- Energy-efficient operation
- Pressure clamp terminals for quick wiring
- DIN rail mounting (35 mm)
- Compact aluminum housing
- Maintenance-free design
- Ideal for preventing condensation and frost formation in electrical cabinets
