There are two main types of finned heating tubes: dry-fired electric heating tubes with fins and dry-fired electric heating tubes without fins. Unless limited by the installation space, most of the air dry firing electric heating tubes are made with fins. Some people have to ask why dry firing electric heating tube with fins, today we will talk about the benefits of dry firing electric heating tube with fins.
Types of finned electric heating tubes.
1、Winding type fin electric heating tube
This normal is to use 6, 7mm steel band evenly wrapped around the stainless steel tube.
2、Square fin electric heating tube
It is a rectangular fins a piece of string in a U-shaped electric heating tube or two straight bar electric heating tube.
The above two kinds of fin electric heating tube are in the original dry electric heating tube on the basis of the addition of iron or stainless steel sheet, the purpose of doing so is to increase the dry electric heating tube heat dissipation area so as to speed up the dry electric heating tube heat dissipation speed, and thus protect the service life of the dry electric heating tube. This is the benefit of the dry heating tube with fins.
