Product Configuration
The unit cooler tubular defrost heater element of the air cooler blower is one of the key components in the refrigeration system, specifically designed to remove the frost layer formed on the surface of the evaporator due to low-temperature environments. The core function of tubular defrost heater for unit cooler lies in efficiently converting electrical energy into thermal energy, melting the ice layer adhering to the fins of the unit cooler blower, thereby ensuring the operational efficiency of the refrigeration system and the smoothness of air circulation.
Specifically, the tubular defrost heater for unit cooler component typically uses high-quality 304 or 316 stainless steel as the outer casing material, with nickel-chromium alloy heating wires inside. The selection of these materials not only ensures the component's corrosion resistance and durability but also gives it excellent high-temperature performance, capable of withstanding working temperatures exceeding 500℃. Additionally, this component is suitable for a wide range of temperatures, from as low as -30℃ to as high as 50℃, and can operate stably under various climatic conditions.
In addition, the tubular defrost heater for unit cooler is highly flexible in design to meet the requirements of different models of cold air blowers. It has various interface forms, including straight single-tube, A-A type (double straight tubes), and U-shaped tubes, with lengths ranging from 0.64 meters to 3.35 meters. The unit cooler defrost heater tube diverse design enables the defrosting heater to be easily adapted to various specifications of cold air blowers, such as the common DD15/DD30(40) and DD60 series unit cooler.

Product Features
1. Defrosting
The chiller's surface is vulnerable to frost in low-temperature environments. To maintain regular equipment performance, the tubular defrost heater for unit cooler melts the frost layer by heating.
2. Improve efficiency
the frost layer will hinder air circulation and heat exchange, and the tubular defrost heater for unit cooler can effectively restore the heat exchange performance of the chiller.
3. Increase the equipment's lifespan
Frequent defrosting can lessen the strain on the machinery and prevent harm from an excessively thick layer of frost.
Product Application
1. cold storage cooling fan : tubular defrost heater used for unit cooler evaporator defrost, prevent frost accumulation affect refrigeration efficiency ;
2. cold chain equipment : U shape defrost heater Maintain the constant temperature environment of refrigerated truck and display cabinet to avoid frost resulting in temperature control failure ;
3. industrial refrigeration system : defrost tube heater is integrated in the bottom of the water pan or condenser to ensure the continuous operation of the equipment
