In this type of HAG, bare wire heating elements are made to pass through numerous channels of high temperature ceramic formers and are electrically and thermally insulated from each other up to the required extent. Fresh and dust-free air is then forced through these high temperature premium grade alloy elements that can withstand bare element alloy skin temperatures up to 800℃.
This construction is used in these types of hot air generators. It is a method of heating dry air that reduces the start-up time of the heater considerably (working temperature is reached in a few seconds) and allows high temperatures to be achieved from small areas, ideal for applications requiring low CFM with high temperatures.
Supplied with or without a suitable blower, these hot air generators reliably produce the desired result. They can be used in single throw systems and recirculation systems. Temperatures up to 350℃ can be achieved in single throw models using these hot air generators.
