Cast aluminum heaters are electric heaters with tubular electric heating elements as the heating body, encased in an aluminum alloy shell formed through die casting. Their operating temperature typically ranges from 150 to 450 degrees Celsius and are widely used in plastic machinery, mold heads, cable machinery, chemical industry, rubber, and oil equipment.
Technical Specifications
The cast aluminum electric heater features a surface load of up to 2.5-4.5 W/cm², with operating temperatures ranging from 300-450°C.
2. Cast aluminum heaters are highly efficient and evenly distributed heaters with good thermal conductivity metal alloys, ensuring uniform surface temperatures and eliminating hot and cold spots on the equipment. They offer long service life, excellent thermal insulation, strong mechanical properties, corrosion resistance, and magnetic resistance. By adding insulation to the external heat dissipation surface and infrared烧结 to the internal heat dissipation surface, electricity consumption can be saved by 35%.
Cautionary Notes
1. Aluminum casting electric heating coils should be properly positioned and secured. The effective heating area must be tightly sealed against the heated object, and burning in a vacuum is strictly prohibited. In case of dust or contaminants on the surface, they should be cleaned promptly before use to prevent heat dissipation issues and extend the lifespan.
2. Magnesium oxide powder at the electrical heating tube's outlet end; prevent pollutants and moisture from seeping in at the usage site to avoid electric leakage accidents.
3. The wiring section should be placed outside of the heating and insulation layers; the housing should be effectively grounded. Avoid contact with corrosive, explosive substances, and moisture. The lead wires should be able to withstand the temperature and heating load of the wiring section for a long time; avoid excessive force when tightening the connection screws.
