CE Certified Electric Duct Heater for HVAC Supply Air System

Power selection depends on your airflow volume , required temperature rise, and ambient temperature. If the power is too low, it won't reach the target temperature; if too high, it wastes energy and causes thermal stress. We provide free professional thermal calculation services to ensure the equipment perfectly matches your duct dimensions and heating needs.

Safety is our top priority. Our heaters feature multiple interlocking protections, including over-temperature control, dry-burning prevention, and an auto-shutoff mechanism that cuts off power immediately if airflow fails. All our products comply with international safety standards and can be customized with explosion-proof designs for hazardous environments.

Made of high-quality stainless steel finned tubes and special alloy materials, our heating elements are designed to withstand high-pressure airflow and have a very long service life. Maintenance is straightforward: we recommend periodic cleaning of dust on the elements and checking electrical connections. Modular designs also allow for quick replacement if needed.

Absolutely. We offer extensive customization options. For corrosive environments, we use special alloys or anti-corrosion coatings. For flammable and explosive areas, we provide certified explosion-proof models. You can also customize voltage, control systems (like PID smart control), and flange types to fit your exact industrial application.

We stand behind our quality with a standard 12 to 24-month warranty on core components. Our technical team provides 24/7 online support, remote troubleshooting, and detailed installation/maintenance manuals. For bulk buyers, we also guarantee a steady supply of spare parts to minimize any potential downtime.
