1.Brief
Copper casting (aluminum) electric heater is will electric heating element bending forming casting in specific to the shape of the copper.
2.Features:
1). The heating temperature is high, Aluminum electric heater is the highest working temperature is up to 400 °C; Copper casting electric heater is the highest working temperature is up to 650 °C;
2), heat transfer effect is good, the non-ferrous metal aluminium or copper as media, copper coefficient of thermal conductivity of 0.94 W/m.K, The aluminum the coefficient of thermal conductivity of 0.53 W/m.K;
3), the heating temperature even, the wall installation forms, and be heating equipment interface after car processing, effective and equipment close together joint;
4), long service life, electric heating element fever length in all cast in casting, no direct contact with the media;
5), mechanical performance is strong, made of copper (aluminum)electric heater is forming integral casting, with good mechanical properties;
6).Size, the biggest than 6 m in diameter, maximum weight: aluminum electric heater less than 1 T; Copper casting electric heater less than 3 T
7). shape according to user requirement of process customization, non-standard design, such as round, hemicycle, right Angle shape and arbitrary shape several combination;
8), maximum thermal load: aluminum electric heater for 6 W/C square, generally take 3 ~ 4 W/C square; Copper casting electric heater for 8 W/C square, generally take 3.5 ~ 4.5 W/C square
9), explosion-proof level: Exd level two BT4;
10), electrical control as shown in the electric control system and solutions
3.Appliance
Can be widely used in plastic machinery, die head, cable machinery, chemical industry, rubber, oil, and other equipment
