Description
The The NTL 411-300W heater, intended for larger enclosures or installations in harsher climate conditions — high-altitude sites or areas with very low ambient temperatures, where a faster, sustained heating response is needed to prevent condensation and freezing of electrical components.
Based on semiconductor (PTC) technology with a built-in thermostat, this variant prioritizes heating capacity over energy efficiency.
Applications:
- Large outdoor enclosures
- Installations in areas with low ambient temperatures (high plateau, high-altitude sites)
- Panels that need fast heating after cold starts
