Product Configuration
The defrost heating tube element for the cold air blower is a dedicated electric heating element in the refrigeration system, which is used to remove the frost layer on the surface of the evaporator. Its core function is to convert electrical energy into thermal energy to melt the ice layer formed on the surface of the cold air blower fins due to low temperature, maintaining the refrigeration efficiency and air circulation.
The defrost heater tube for air cooler is made of 304 or 316 stainless steel tube and is equipped with a nickel-chromium alloy heating wire, with a temperature resistance of over 500℃, suitable for working conditions ranging from -30℃ to 50℃. The interface design of the cold air chiller defrost heater is flexible, supporting straight single tubes, A-A type (double straight tube ),U-shaped elbows, and other forms, with lengths ranging from 0.64 meters to 3.35 meters, suitable for different cold air blower models (such as DD6, DD60 series).

Defrost Heater for Air-cooler Model
Product Function
1. Defrosting：
In a low temperature environment, the surface of the chiller is prone to frost, and the defrost heater tube melts the frost layer by heating to ensure the normal operation of the equipment.
2. Improve efficiency:
the frost layer will hinder air circulation and heat exchange, and the defrost heater tube element can effectively restore the heat exchange performance of the chiller.
3. Extend the life of the equipment:
regular defrosting can reduce the load of the equipment and avoid damage caused by too thick frost layer.
Selection Precautions
*** Power matching: Select the appropriate defrosting heater power according to the specifications of the chiller and defrosting requirements.
*** Size adaptation: the length and shape of the defrosting heater should be matched with the evaporator to ensure uniform heating.
*** Corrosion resistance: Choose corrosion-resistant materials (such as stainless steel pipes) to adapt to humid environments.
Product Application
The defrost heater element is mainly used in refrigeration equipment such as cold storage fan and commercial refrigeration display cabinet, especially for scenes where frost layer is frequently formed under medium and low temperature environment (-40℃~10℃) .
