Product Description
- The defrost heating tube is a metal tubular electric heating element, with a metal tube (usually 304 stainless steel for its good corrosion resistance) as the outer shell.
- The heating element is an alloy heating wire, commonly made of nickel-chromium alloy resistance wire or iron-chromium-aluminum wire.
- Dense magnesium oxide powder is filled in the metal tube as an insulating medium to fix the heating element, with lead rods (wires) at one or both ends for connecting to the power supply and between elements.

Characteristics
- Excellent defrost effect: Quickly and effectively melts the frost on the evaporator surface to ensure the normal operation of the refrigeration device.
- High electrical strength: Can withstand high voltage, preventing electrical breakdown and other failures during operation.
- Good insulation resistance: The use of insulating materials like magnesium oxide powder ensures the heating tube has excellent insulation performance, reducing the risk of electric leakage.
- Corrosion-resistant and anti-aging: The stainless steel shell and high-quality insulating materials enable it to resist the erosion of harsh environments and extend service life.
- Strong overload capacity: Can withstand loads exceeding the rated power to a certain extent, and is not easily damaged by short-term overload.
- Small leakage current: Operates stably and reliably, ensuring the safety of equipment and users.





Application Scenarios
- Refrigerators: Prevents excessive frost on the evaporator surface, which may affect cooling efficiency and increase power consumption. The defrost heating tube is usually installed near the evaporator to defrost the evaporator regularly and maintain the refrigerator's normal operation.
- Cold storage: Equipment such as cooling fans and condensers in cold storage are prone to frosting during operation. The defrost heating tube can be embedded in the fins of these equipment or at the bottom of the water receiving pan for regular defrosting, ensuring the refrigeration efficiency of the cold storage and the storage quality of goods.
- Freezer and refrigerator display cabinets: Used in freezer and refrigerator display cabinets in supermarkets, convenience stores, etc. The defrost heating tube can timely melt the frost on the evaporator surface of the display cabinet, maintaining the good display effect and refrigeration performance of the items in the display cabinet.
