Diameter 6.6MM Stainless Steel Sheath Flexible Tubular Heater For Hot Runner Manifold
Produce Description
Tubular heating elements perform exceptional heat transfer by conduction, convection or radiation to heat liquids, air, gases and surfaces. Tubular heating elements are also used for radiant heating in open air or in vacuum atmospheres.
It is the most versatile heating appliance among all electric
heating elements.In most heater assemblies, tubular element design
configurations vary — round, triangular, flat press and formed.
Tubular heater is used for almost every kind of heating appliances. They are easy to form and feature highest mechanic stability and electric properties at the same time. Even though tubular heaters are technically rather mature and universal to use, there exist various new innovative solutions for many applications. Screw in tubular heaters are standardized for use in liquids like water. Finned tubular heaters are especially for air heating cabinets or tunnels. Flanged heater are easy to install, control and maintain, unique designer as your requirement. For corrosive environment, titanium material or tubular heating elements with additional sleeving are available .

Feature
1. Designed and built for safety.
2. Broad variety of sizes for different applications;
3. Compact;
4. Easy to maintain;
5. Energy -saving, efficient
6. Flexible tubular heater should be protected against damp during
storing or installing to ensure the performance of the heater.
7. In order to be sure of well-distributed load of each and groups
heater should be divided before assembling.
8. The tolerance of the resistance of each one can not exceed by
10% each other.
9. At the beginning of the operating the electric furnace
, the voltage should be increased slowly and can not be fully
loaded at once. Otherwise the larger current will be resulted
in the damage of heater
10 . Heater is hard and brittle, please be careful when
assembling and maintaining so as to avoid damage.
11.When heater is damaged and need to be changed , the resistance
of new heater should follow the increasing resistance. If many
are damaged or resistance increased too much, all the heater should
be changed.
