The application of Hua...

In cold areas, the temperature can be as low as -20-30℃. Industrial pipeline insulation alone cannot prevent the fluid in the pipeline from freezing. After freezing, the fluid tends to expand. When it expands to a certain extent, it may cause the pipeline to rupture. Huanrui pipeline electric heating system realizes thermal compensation for the pipeline system to avoid the rupture of the pipeline due to the expansion of fluid freezing. Reliable pipeline electric heating antifreeze solution The electric heating system prevents the freezing of non-flowing water in pipelines, pumps and related equipment by compensating for the heat loss of the insulation layer. Anhui Huanrui pipeline electric heating system is energy-saving, reliable and high-performance. Our electric heating antifreeze solutions are often used in industrial facilities: Water supply and drainage pipelines Fire protection and sprinkler systems Tank water tanks We provide electric heating solutions with various technologies to solve the troubles of winter pipeline antifreeze.

Mineral insulation technology: Suitable for applications requiring high power output, high exposure temperature, or corrosion resistance in extreme environments.

The winter climate is relatively cold, especially in northern regions where the temperature can often drop to dozens of degrees below zero. When it encounters rain and snow, it is easy to form snow accumulation, which is difficult to melt due to the low temperature. The previous snow may not melt, and the next snow may start to fall again, which will cause more and more snow on the gutter or road, affecting the safety of houses and travel. In order to eliminate potential safety hazards and provide people with a safe and open living and living environment, Anhui Huanrui also provides suitable electric heating solutions for roof snow melting and ground snow melting application needs. Roof gutter snow melting and deicing system The severe cold weather in winter poses huge safety risks to commercial and industrial buildings. When the snow on the roof and gutter freezes, the melted water will form icicles hanging on the eaves, and even cause the downpipe to be blocked or burst. However, most roofs can only withstand 27 kilograms of snow per square meter, which further increases the safety risk. In order to solve this problem, Anhui Huanrui's roof and gutter snow melting and deicing system came into being. The system can clear snow in time, provide safety protection for commercial and industrial buildings, and ensure that people can live and work safely in the cold winter. Huanrui roof gutter snow melting and deicing system electric heating products are designed with UV-resistant outer sheaths, which can be immersed in snow water and can work stably in an environment of minus 40 degrees. It can adjust the heat output according to the ambient temperature, and only generate heat at the location where snow melting and deicing are required, with low energy consumption, high system safety, strong adaptability and reliability. Easy to install, the system includes electric heating products, intelligent thermostats, connectors, etc. The entire design and installation process is very simple and easy to operate, which greatly saves time and cost. Huanrui roof snow melting and deicing system is widely used and suitable for various roofs such as metal and plastic. The system has a long service life, is safe and reliable, durable, and reduces maintenance costs.

Anhui Huanrui's ground snow melting system solution is an innovative approach that can be widely used in maintenance areas, cargo loading and unloading areas, porches, entrances and exits, vehicle and pedestrian passages, ramps and other locations to meet the requirements of commercial, industrial and...

Heating cable system is used for snow and ice melting on the roof of plant seedling greenhouse The heating cable system is used for snow and ice melting on the roof of plant seedling greenhouse. In seasons that are not suitable for plant growth, greenhouses can provide greenhouse growth periods and increase production. They are mostly used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees and other plants in low temperature seasons. It is an important facility for winter agricultural development. The heating cable system is used for snow and ice melting on the roof of plant seedling greenhouse. In northern regions in winter, due to the relatively low temperature, the snow is difficult to melt after snowfall. As time goes by, it will accumulate deeper and deeper, and it is likely to crush the roof of the greenhouse. At this time, it is necessary to clear the snow. For this purpose, the heating cable snow and ice melting system can be used. It uses the heating cable to heat up to melt the ice and snow on the greenhouse, ensuring that the greenhouse roof is not damaged by freezing. The heating cable snow melting system can design a reasonable electric heating snow melting plan according to the local ambient temperature, the length and width of the greenhouse roof, etc. The electric heating system has the advantages of fast heating, uniform heating, simple installation, convenient use, safety and environmental protection, and energy saving. At present, heating cable systems have been widely used in many fields such as building electric floor heating, breeding plant insulation, greenhouse vegetable seedling cultivation, geothermal cultivation, etc.
