Watlow LDH SERIES Duct Heaters

Watlow duct heaters are designed for efficient performance in non-pressurized air heating systems. Constructed with robust 0.430 in. (11 mm) diameter WATROD heating elements mounted to a 1⁄4 in. (6 mm) thick steel flange, these duct heaters deliver consistent and precise heat, making them ideal for a wide range of industrial applications.

Key Features of Watlow Duct Heaters: 

• Modular Design for Easy Maintenance:  Each duct heater features removable modules, reducing downtime and maintenance costs by allowing for quick, on-site replacement without removing the entire assembly. 
• Energy Efficiency and Flexibility: Watlow duct heaters provide 100% energy efficiency with no energy loss, eliminating the need for fuel lines or exhaust systems. 
• Durable, Long-Lasting Performance: Ther corrosion-resistant sheath protects the heating coil, extending the lifespan of the duct heater even in harsh industrial environments. 
• Improved: Airflow Control: Faster response times and reduced air leakage into the electrical enclosure improve overall efficiency and temperature control. 
• High Voltage Capability: Designed for 480 and 600 VAC maximum ratings, with UL@ and CSA component recognition (UL® file E52951 and CSA file 31388).

Watlow duct heaters are built to deliver reliable, high-performance heating for industrial and HVAC systems, ensuring efficient operation and long-term durability.
