Duct Air Heaters

Duct Air HeatersDurex Industries manufactures rugged process duct air heaters that are well suited for the needs of many heavy duty industrial applications. Incoloy® tubular heater elements for long life and durability. We construct high tensile strength cages to support heater elements in larger, higher temperature units to ensure proper air heater performance. The optimal sheath material and maximum allowable watt densities are used to minimize size, weight, and footprint. Replaceable heating element designs, as well as modular "bank" type designs, are available.

Durex’s HT (High Temperature) duct heaters are designed for high process temperature applications to 1200°F (650°C), while Durex’s MT (Medium Temperature) duct heaters are for more economical, lower temperature applications to 750°F (400°C).
