Duct Heater

Forced Air Duct Heater - for Industrial Process Heating Only

Ovens often require re-circulated air, or forced circulation, to perform the desired heating task. A duct heater mounted in this re-circulated air stream is an effective way to provide this heat, without having any electrical connections inside your oven.

Typical Applications

• heat treating, up to1000°F (540°C)
• curing
• baking
• drying
• batch heating
• conveyor systems

Typical Air Heat Calculation

kW - kilowatts
SCFM - standard cubic feet per minute
Temperature rise - number of degrees Fahrenheit increase required

A 20% safety factor is highly recommended
