Characteristics of cast aluminum heaters

Cast aluminum heaters are widely used in plastics machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemical, rubber, and petroleum equipment. Cast aluminum heaters utilize a tubular electric heating element as the heating element, which is bent and formed. The housing is constructed of high-quality metal alloys and centrifugally cast into various shapes, including round, flat, right-angle, air-cooled, and water-cooled. Once completed, they can be tightly bonded to the heating element, with a maximum operating temperature between 300-450°C.

Instructions for Use of Cast Aluminum Heaters:

1. The operating voltage should not exceed 10% of the rated value. The relative humidity should not exceed 95%, and there should be no explosive or corrosive gases.

2. The wiring should be placed outside the heating layer and insulation layer, and the housing should be effectively grounded. Avoid contact with corrosive, explosive media, and moisture. The wiring should be able to withstand the temperature and heating load of the wiring for extended periods. The wiring screws should be tightened to avoid excessive force.

Advantages of Cast Aluminum Heaters:

1. Large heat exchange area, fast heat exchange rate, and high efficiency.

2. Long heating time, long pipe heating, and more efficient heat transfer.

3. High-quality heat transfer medium, fast heat transfer, and rapid heat exchange.

4. The water channels and pipes of the cast aluminum heater are completely enclosed by the pipe. There are no welded connections and no large-area liquid seals to prevent corrosive fluid leakage.

5. The heating element is protected from moisture and the water and electricity are completely separated.

6. The heat load on the heating element is reduced, the size is reduced, and the service life is extended.

7. Due to the heat generated by the contacts, the terminals of the heating element should be located in the low-temperature area of the heating body. The terminals should be dispersed to reduce self-heating and ensure safety.
