Darui Electric recommends for you
It is a cast aluminum heater that uses tubular electric heating elements as the heating body and high-quality aluminum alloy material as the shell, formed by die-casting. Its operating temperature is generally between 150 and 450 degrees Celsius, and it can be widely used in plastic machinery, die heads, cable machinery, chemical, rubber, petroleum and other equipment. The cast aluminum heater features long lifespan, good thermal insulation performance, strong mechanical properties, corrosion resistance, and anti-magnetic field advantages.
1. When the resistance heating coil works, it first heats itself, then conducts to the barrel. During the conduction process, more than 40% of the heat energy is lost directly in the air. In contrast, the electromagnetic induction heater directly heats the barrel through high-frequency electromagnetic wires. The outside of the barrel is installed with insulation materials. When the whole system is working, the external temperature is 60 degrees, and heat energy basically does not dissipate into the air. The electromagnetic heater directly saves 40% of energy consumption compared to the resistance heating coil.
2. The resistance heating coil will automatically stop heating when it reaches the set temperature, but the temperature of the resistance-heated aluminum components is much higher than the barrel temperature, and it continues to conduct heat, causing the barrel temperature to be higher than the set temperature. This requires fan cooling, wasting a significant portion of energy. However, since the electromagnetic induction heater directly heats the barrel, temperature control is accurate, and there is no need for frequent cooling of the barrel temperature, saving 10% of energy consumption compared to the resistance heating coil.
3. The electric heating wire is a conductive heating element. The level of voltage, the quality of tightening, and the oxide film between the heating element and the barrel can directly or indirectly cause damage to the resistance heating element (including the replacement and maintenance of AC contactors), requiring regular replacement of heating coils and AC contactors and other components. However, the electromagnetic induction heater heating system itself does not generate temperature; the high-frequency wires outside the barrel only need to pass current without generating high temperatures, so there is no need for frequent replacement. Moreover, the electromagnetic induction heater system uses intelligent chips to work, does not require AC contactors, and also reduces the operating cost of frequently replacing contactors.
4. Resistance heaters take 30-50 minutes to go from cold to working environment, while electromagnetic heaters of the same power only take 8-15 minutes.
