Industrial Air Duct Heater

Product Details:

Industrial Air Duct Heater heating elements mounted to a 1/4 in. (6 mm) thick steel flange, duct heaters are easily adapted to many nonpressurized air-heating systems. They are easily installed in applications requiring a wide range of temperature versus air flow combinations. The modular duct heater offers increased reliability. The individual modules are removable through the housing of the assembly, which eliminates the need to pull the complete heater from the duct work. This reduces downtime costs because the heating elements can be replaced individually. Performance improvements include quicker response time and reduced infiltration from the air stream being heated into the electrical enclosure.

SAW HEAT ® duct heaters offer advantages over gas or oil fired and open coil electric units with:

• Installation flexibility—no flues or fuel lines
• 100 percent energy efficient—no energy loss up the flue
• Universal availability of electricity
• Resistance coil in sheath is protected from corrosive environments

Features and Benefits 

• Long life alloy sheath Resists corrosion/oxidation while protecting resistance coils against contamination
• MgO insulation filled elements compacted to rock hard density Maximizes dielectric strength, heat transfer and life
• Field replaceable heating element Permits easy service and reduces downtime. Element change-out is made simple by a single screw clamp
• 3 1/2 in. (90 mm) thick mineral insulation Keeps wiring cooler and reduces heat loss Silicone resin seals rated to 105°C Protects elements against moisture and other contaminants
• General purpose terminal enclosure Offers easy access to wiring 1/4 in. (6 mm) inside diameter thermowell 
• Accepts an optional Type J or K thermocouple for accurate sheath temperature sensing
