Hot-Air Heater

This type of heater distributes heat using air as an intermediary for transferring heat to the surface contact. This particular type of heater requires outstanding specification featuring low expansion rate in a high temperature environment. The heater can be maintained in shape under most circumstances and not be easily distorted. It also features corrosion resistant and anti-oxidation. The proper sheath materials can be made from Inconel, Incoloy and Stainless Steel grade 309. Material selection depends heavily on temperature requirements, focusing mainly on load surface (watts per heated area) which can determine its durability.
