Semiconductor Fan Heater with Thermostat 800-1000w DIN Rail/Cabinet Heater

The semiconductor fan heater is a high-performance solution for maintaining stable temperatures and preventing condensation, frost, or moisture-related damage in electrical and electronic enclosures. Designed for professional and industrial applications, it combines robust construction, precise temperature control, and reliable airflow to ensure safe and consistent operation.

Equipped with a PTC resistor heating element, the NTL 1200 automatically limits its temperature, while the temperature safety cut-out protects against overheating in case of fan failure, with automatic reset. The axial fan with ball bearing provides high airflow of 160m³/h and a service life of up to 50,000 hours at +25°C (+77°F), distributing heat evenly throughout the enclosure.

The unit features flexible mounting options, including DIN rail clip (35mm) or screw fixing (M6), and can be fitted in vertical airflow orientation (other positions possible). The integrated thermostat allows precise temperature setting, and the manual on/off switch gives convenient control.
