Tubular heating elements are commonly used in industrial heating due to their versatility and affordability. They are used for heating liquids, solids and gases through conduction, convection, and radiation heating. Capable of reaching high temperatures, tubular heaters are an efficient choice for heavy duty industrial applications.
1.Are you factory?
Yes, we are factory, all customers are more than welcome to visit our factory .
2.What are the available product certifications?
We have certifications such as: ATEX, CE, CNEX. IS014001, OHSAS18001,SIRA, DCI. Etc
3.What are the ambient operating temperature limitations
WNH heaters are certifed for use in ambient temperature ranges from -60 °C to +80 °C.
4.What is the maximum power density of the heater?
The power density of the heater must be based on the fluid or gas being heated. Depending on the specific medium, the maximum usable value can reach 18.6 W/cm2 (120 W/in2).
5.What Mediums Can Tubular Heating Elements Be Used For?
Tubular heating elements can be used for heating a variety of mediums including liquids, gases, and solids. Tubular heating elements in conduction heaters use direct contact for heating solids. In convection heating, elements transfer heat between a surface and a gas or liquid.
