The elements produced by our factory, of which 83 kinds have net the ministerial standard and 37 kinds met the factory standard. They can be used to heat air, liquid and die sets, with the exit wire from one and or both ends. Additionally, we can produce various kinds of nonstandard electrical eating elemengs based on the requirements of customers.

Tubular electrical heating element　

The tubular electrical heating element is a kind of heating element which has metal tube as its outer cover and alloy resistance wire as its heating unit with interspace densely filled with crystalline magnesia, a material which has a pretty good insulatibity and heat conductivity. It can heat both the still air and flowing air, or to be put directly into the water or other liquid to heat up. It can also be used to smelt metal or used as a heating device to make metal mould. Due to its several advantages, the element can be widely applied to many fields such as aviation industry,ship making, petroleum, chemistry, cleaning, mechanical manufactory, auto industry, engines, wireless industry, instruments, plastics, textile, food, print, medicine, household appliance,etc.

　　Characters of tubular electrical heating element:

1、long working life (2-6 years or even 10 years in case of normal conditions);
2、safe and reliable performance;
3、high thermal efficiency;
4、simple structure, material saving;
5、good mechanical properties;
6、wide application;
7、easy and convenient operation

Fin electrical heating elements

Compared with the tubular electrical heating elements, the fin electrical heating elements can be used to warm the flowing air with the advantages of larger heat-sinking area, higher thermal efficiency and lower cost.
