FAQs of Air Duct Heaters:

Q: How do air duct heaters work in industrial HVAC and air handling systems?

A: Air duct heaters use electric heating elements, typically Nickel Chromium (NiCr) alloy, to heat air passing through ducts. They are integrated into HVAC systems, air handling units, exhaust systems, clean rooms, and drying ovens, providing uniform heating and maintaining desired ambient temperatures for various industrial environments.

Q: What control options are available for managing temperature and safety?

A: These heaters support thermostats, digital controllers, and thermocouple sensors for temperature management. They also feature built-in over temperature cut-off for automatic shutdown if overheating occurs, along with earthing protection for enhanced electrical safety.

Q: When should I choose customized sizes, power, or ingress protection for my application?

A: Customization is recommended when specific airflow rates, duct dimensions, or power requirements must be met. IP55 or IP65 ingress protection can be selected based on exposure to dust or moisture, ensuring optimal performance and longevity in varied installation environments.

Q: Where are air duct heaters commonly installed?

A: Air duct heaters are widely used in industrial HVAC systems, clean rooms, air handling units, drying ovens, and exhaust systems. Their flexible mounting options, such as flanged or slip-on configurations, allow adaptation to rectangular or circular ducts in both new installations and system upgrades.

Q: What materials and build qualities enhance the durability of these heaters?

A: Manufactured with stainless steel or galvanized iron and insulated with mineral or ceramic wool, the heaters resist rust and withstand high temperatures. The robust construction and quality finish help endure continuous operation in harsh industrial settings, maintaining efficiency and reliability.

Q: How do these heaters ensure uniform heating and easy installation?

A: The design incorporates evenly distributed NiCr alloy heating elements, promoting consistent air temperature across the duct cross-section. Terminal box options (IP55/IP65) and screw/stud terminal connections enable straightforward installation, whether mounting is flanged or slip-on style.

Q: What are the benefits of using these air duct heaters in industrial applications?

A: The main benefits include precise temperature control, fast and uniform air heating, reliable overheat protection, resistance to corrosion, and easy maintenance. They comply with IS and IEC standards and offer customization, making them ideal for diverse industrial scenarios.
