Darui Electric recommends
The flat electric heating strip is developed by our company using international advanced electric heating element manufacturing technology combined with new electric heating materials. Due to its strict inspection by precision instruments, it is safe, efficient, and durable, making it one of the industrial preferred heat sources. It is a type of heater that closely adheres to the metal surface.
Product Structure:
The basic structure of the flat heating strip is: spiral heating wires are placed on both sides of the center of the metal protective tube. A specially designed bracketless automatic powder filling machine fills high-temperature resistant, excellent insulating, and good thermal conductivity high-purity magnesium oxide evenly into the protective tube, preventing the heating wire from shifting. Then, a fully automatic continuous tube shrinking machine presses the protective tube into a flat shape, expelling the air between the magnesium oxide powder. This not only protects the heating wire from oxidation but also transfers the heat generated by the heating wire to the heated object. It also has the advantages of large contact area, fast heating speed, high heat transfer efficiency, space saving, high power, fast temperature rise, high reliability, strong heat capacity, and long service life.
Product Performance:
The flat heating strip is trusted by customers, with the highest professionalism and the best durability.
High Efficiency: The high-precision flat heating strip developed through years of research and practice. The heat generated by the flat heating strip can be transmitted without loss.
Long Life: The heating wire uses nickel-chromium heat-resistant alloy. Due to the use of heat-resistant insulating magnesium oxide, it has a longer life than previous products.
Robustness: The outer protective tube is stainless steel (GH3030). The design withstands mechanical vibration and impact, and is a robust structure that has passed long-term testing.
Electrical Performance: Excellent electrical insulation, especially maintaining stable insulation performance at high temperatures.
Operability: Multiple heating rods can be used simultaneously, and wiring can be done very smoothly without obstacles.
Rich Variety: To meet various customer needs, we have a wide range of specifications.
