Solar water heaters are installed and used in most areas of Northeast China. All of them are facing the problem of low winter temperatures and easy freezing and blocking of pipelines, which is a headache for the majority of solar water heater dealers. Most of the after-sales service of solar water heaters is concentrated in winter, and most of the failure rate in winter is directly related to the freezing of the pipeline.
The climate in Northeast China is relatively cold. Generally, a wider solar power heating cable is used. Ordinary solar power heating cables are easy to burn. The DKW-Da series solar power heating cables developed by Anhui Cable Group are suitable for Northeast China.
DKW Northeast special solar power heating belt (commonly known as thawing zone or antifreeze zone)
DKW Northeast special solar electric heating cable (commonly known as defrosting zone or antifreezing zone ) The current flows from one wire core through conductive PTC material to another wire core to form a loop. Electrical energy heats up the conductive material, and its resistance increases immediately. After a certain value, the resistance is large enough to almost block the current, and its temperature no longer rises. At the same time, the electric heating cable transfers heat to the heated system with a lower temperature. The power of the electric heating cable is mainly controlled by the heat transfer process, and the output power is automatically adjusted according to the temperature of the heated system, but the traditional constant power heater does not have this function.
1. The temperature of the heat tracing pipeline is uniform, will not overheat, and is safe and reliable;
2. Save electricity;
3. During intermittent operation, the heating starts quickly;
4. Low installation and operation costs;
5. Easy installation and maintenance;
6. Facilitate automated management;
7, no environmental pollution;
Instructions for use
When using this product to heat and thaw a solar water heater, remember to configure a leakage protection switch.
The maximum length of the solar heating cable is related to the load and the cross-section of the conductive core of the heating cable. If the heating length exceeds 10m, the thermal design must be selected according to the design manual to avoid misuse.
The tail end of the electric heating belt should adopt a fire-resistant heat-shrinkable tube fireproof envelope after cross-linking with radiation. If insulating tape is used, it will be short-circuited after a long time. Our company's solar electric heating belt is equipped with a dedicated heat-shrinkable sleeve for users.
