Product Presentation:
Application:
It is suitable for the electric heating environment with the rated voltage below 250V, 50 ~ 60Hz, the relative humidity of not more than 90% and the ambient temperature of minus 30 DEG to plus 50 DEG. With a rapid, uniform and safe heating, it is widely used in the thawing of the refrigerator and other electric heating appliances.
Characteristic:
With the aluminum tube as the carrier, the electric heating component with various shapes which is made by placing the silicone rubber heating wire in the aluminum pipe has the maximum temperature of below 150 DEG C and due to that the outer diameter can be divided into two types of φ4.5 and φ6.35, we recommend a design power of less than 35W/m, the products exceeding the above power density should be customized and designed by our company.
