Product Configuration
PVC door frame defrost heater is an electric heating element widely used in low-temperature heating scenarios. With its outstanding performance and diverse application scenarios, the defrost heating cable holds an important position in industries, household appliances, and medical equipment fields.
The core components of PVC door frame heating cable include electric heating wires and a PVC insulation layer. The electric heating wires are typically made of materials such as nickel-chromium alloys, which have high resistivity and good oxidation resistance, ensuring stable heating performance over long periods of use. The PVC insulation layer provides excellent protection for the cable, endowing it with flexibility, corrosion resistance, and outstanding insulation properties. These characteristics enable PVC heating wire cables to operate stably in various complex environments.
Common PVC door frame defrost heating wire cables use insulating materials that can withstand temperatures up to 105°C, ensuring the reliability and safety of the cables under high-temperature conditions. Therefore, The PVC defrost wire heater cable is highly suitable for scenarios requiring precise temperature control, such as the compensation heating system in the freezer compartment of a refrigerator. By installing such heating wires in the freezer, frost formation can be effectively prevented, thereby enhancing the refrigeration efficiency and extending the lifespan of the equipment. Additionally, the PVC defrost heating cable is widely used in medical devices, such as blood refrigerators or laboratory temperature-controlled apparatus, to ensure that sensitive items are preserved within an appropriate temperature range.

To meet the diverse needs of different customers, we offer PVC defrost heating wire products in various specifications. Depending on the actual application, heating wires of different diameters can be selected and paired with single or double layers of 105°C PVC insulation. For higher-demanding application scenarios, a version with a metal braid layer is also available. This design not only enhances the mechanical strength of the cable but also provides grounding protection, further improving the safety and stability of the system.
Product Function
Cold storage door frame heating wire is not long-term energized. The working principle of the defrost wire heater is based on Joule's law, which is that the current converts electrical energy into heat energy. Electric heating means that after the current passes through the conductor, the current will generate a certain amount of heat and be transferred by the conductor. The defrost door heater wire itself is a metal conductor, and it will emit heat after being energized, thereby providing heat to melt the frozen door crack and prevent the door crack from freezing to death. After the electric heating wire is energized for a period of time, it will automatically cut off the power supply. The heating line will hold heat for a period of time, and after the temperature drops, it needs to be re-energized for heating.
