When a well-known car company's ro-ro ship crosses the vast ocean, the temperature on board may drop to dozens of degrees below zero. In the past, such extreme conditions may cause the fuel pipeline to solidify, instrument components to freeze and crack, and water supply pipelines to freeze, causing significant losses. Today, Huanrui Electric's heating system provides all-weather "warm protection" for ro-ro ships. Installing self-regulating temperature electric heating cables in key areas of ro-ro ships is like putting on an intelligent temperature control jacket for the equipment. It can automatically adjust the output power according to the changes in the external temperature. The lower the temperature, the greater the heat output. When the temperature rises, the power is automatically reduced to achieve precise heating. Firefighting and water supply pipeline network The firefighting pipelines of the entire ship run through the deck like blood vessels. Once frozen, water will not be able to be supplied to extinguish the fire in an emergency. The self-regulating temperature electric heating cables are laid close to the pipelines, and the intelligent temperature control ensures that the water flow in the water pipes is always in liquid state. Even in the high and cold sea areas of the ocean, the firefighting system can still respond at any time. Fuel and lubrication system ：Once the fuel pipeline of a ship solidifies at low temperature, the main engine will shut down. The self-regulating temperature heating cable forms a dynamic insulation network on the fuel pipeline to ensure the fluidity of the fuel. The corrosion resistance of its outer fluoroplastic sheath resists the chemical erosion of marine fuel. Key instruments and valves ：Hundreds of pressure gauges, level gauges and valves on the ship are the "eyes" of operation monitoring. Traditional heating is difficult to heat evenly in these precise parts, while the self-regulating temperature heating cable can be laid in a shape-fitting manner and fits tightly to irregular surfaces through aluminum foil tape to prevent instrument freezing and cracking. The ocean-going export of vehicles of a well-known automobile company has realized the complete industrial chain closed loop of "Chinese ships, Chinese manufacturing, Chinese vehicles, and Chinese transportation". As an important "antifreeze and heat preservation solution", Huanrui's electric heating system ensures the quality and safety of domestic cars in long-distance shipping and enhances the international image of Chinese automobile brands. Opening up a new blue ocean for shipbuilding: This successful application marks that Huanrui's products have entered the field of automobile ro-ro ships, opened up a new market for heating, and brought huge development space for Huanrui. Verify the technical strength of extreme environments: Ocean-going ships are the "ultimate examination room" for testing the performance of e...

Tunnels play an important role in modern transportation infrastructure, especially in complex terrain conditions. They provide safer, faster and more stable passages for traffic. The safety and reliability of pipelines are also crucial in modern tunnel construction and operations. In winter, the average temperature in the tunnel will drop, and the water supply, drainage, fire protection and other pipes in the tunnel are easily blocked by freezing, affecting the flow of media in the pipes. With its unique technical advantages, Huanrui's electric heating system has been successfully used in many important tunnel pipeline insulation projects, demonstrating its ability to maintain pipeline temperature stability in cold environments. Shenyang Expressway Tunnel Fire Protection System Electric Heating Belt Antifreeze and Insulation Project The extreme low temperature in the Shenyang Hunnan Avenue Expressway Tunnel in winter can reach minus 30.6°C, and the average temperature is around -10°C. The electric heating tape system for tunnel firefighting pipes provided by Huanrui is to directly lay or wrap the electric heating tape closely to the surface of the firefighting pipe to supplement the heat loss, and adjust the water temperature at each control point of the pipeline system along its own length. , to maintain the water temperature within the required temperature range, thereby achieving the purpose of preventing pipes from freezing. The Huanrui electric heating system has been successfully applied to the pipe insulation in the tunnel. Through the continuous heating of the system, the normal operation of the water supply pipeline in the tunnel is ensured and the water supply interruption caused by low temperature in winter is prevented. In addition, the system's automatic adjustment function effectively reduces energy consumption and improves economic benefits. Queershan Tunnel Pipeline Electric Heat Tracing Insulation Project The main peak of Que'er Mountain is 6,168 meters above sea level. It is covered with snow for up to 8 months every year.

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.

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. Ground snow melting and deicing system Due to ice and snow weather,people are prone to serious injuries in winter due to slips, trips, and falls. In addition, the risk of car accidents in parking lots and loading and unloading docks has also increased. Therefore, ensuring that the access to and from the building is free of ice and snow, especially in areas with frequent personnel movement, should be a priority. 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...
