Design Features
High-Temperature SS Sheathed Elements:
Stainless steel-sheathed tubular elements withstand temperatures up to 750°C and are field-replaceable, making maintenance quick and cost-effective.
Durable Construction:
Heavy gauge stainless steel or galvanized steel mounting flanges offer excellent corrosion resistance, minimize oxidation, and promote longer operational life.
Versatile Mounting Options:
Units are compatible with both horizontal and vertical duct installations, allowing flexible integration into existing air handling systems.
Technical Specifications
Finned Tubular Heating Elements: Stainless steel sheathed with fins for enhanced heat transfer efficiency. Capable of operating at 450°C maximum with incoming air at 25°C and a minimum air velocity of 550 FPM.
Low Air Velocity Operation:
For systems with airflows between 200–360 FPM, outlet temperatures should be limited to 450°C to ensure heater lifespan and safe operation.
Terminal Cooling Options:
Removable end plates on the terminal box enable auxiliary cooling of terminals in high-temperature environments. Optional perforated grills allow natural convection air flow across the terminals.
