Product Configuration
The defrost tube heater for fridge is an important component in the refrigeration system. In order to maintain the refrigerator's refrigeration efficiency, the defrost heater tube's primary function is to melt the frost that has accumulated on the evaporator during the automatic defrosting cycle. The refrigerator's defrost heater tube for fridge, which is 20 inch or longer and compatible with the freezer evaporator's construction, is composed of 304 stainless steel, which has a high resistance to corrosion. The electricity is generated in accordance with specifications, and the voltage can be adjusted between 110 and 230V.
Typically, electric heating wires and insulating materials make up refrigerator defrost heater tubes for fridge. They produce heat when they are powered on. The refrigerator's defrost heater for fridge begins to melt the frost layer on the evaporator as soon as the defrost timer or control board delivers a signal. The drain pipe is used to remove the melted water from the refrigerator during the defrosting operation.

Defrost Heater for Air-cooler Model
Product Features
Effective management of temperature and frost
*** To guarantee refrigeration efficiency, the defrost tube heater for fridge rapidly melts the coating of ice on the chiller's evaporator or condenser surface. The refrigerator defrost heater works well in temperatures between -30°C and 50°C.
*** Accurately match the defrosting cycle, support segmented heating (e.g., 1000W–1200W power range), and heat up to 400°C per hour.
Durability and safety
*** Stainless steel shell that is resistant to corrosion, mechanical impact, and has a life of up to 4500 hours;
*** Insulation that is resistant to leaks and has a resistance of at least 60MΩ, which helps to prevent electrical hazards in humid environments.
Flexible adaptation
*** The producer of defrost tube heaters for fridge allows for non-standard customization (e.g., pipe diameter 8.0mm, length 1.3m), which is appropriate for complex structures like evaporator fins and chiller chassis;
*** Equipment for cold chain transportation, commercial cold storage, and residential freezers are all compatible with 220V and 380V electricity.
Product Application
1. Direct cooling/air-cooled refrigerator : the defrost heater for fridge used under the evaporator or in the variable temperature return air duct to melt frost on the surface of the evaporator and prevent the return air duct from freezing (such as the air-cooled refrigerator to achieve rapid frost through the aluminum tube heater).
2. Cold storage and refrigerated display cabinets :
*** Solve the problem of evaporator frosting in low temperature environment to ensure the refrigeration efficiency of cold storage.
*** Commercial reefer adopts variable power design to adapt to different environmental humidity requirements .
3. Ship and cold chain transportation : refrigerated container defrosting system adopts waterproof heating pipe to adapt to high humidity environment .
