China's successful bid to host the 24th Winter Olympic Games in 2022 kicked off the rapid development of China's ice and snow industry. The "National Ice and Snow Site Facilities Construction Plan (2016-2022)" proposes that by 2022, the number of ski resorts in my country will reach 800, the snow track area will reach 100 million square meters, and the snow track length will reach 3,500 kilometers. Promote the long-term prosperity and development of the ice and snow industry. Atlas Copco just caught up with this good time and will be committed to contributing to the sustainable development of China's ice and snow sports industry! The snowmaking process of ski resorts must be inseparable from automated snowmaking equipment. Henan Jinan Machinery Technology Co., Ltd. is the largest ski resort equipment manufacturer in China. Its main products are "Nuotec" snow guns, "Manlin" skis and ski magic carpets. Its products have been sold in 17 provinces and regions in China and 11 countries in the world, and have been widely recognized by users in the ice and snow industry.

Jinan Company started mass production of snow machines as early as 2014. At that time, it was equipped with a certain brand of sliding vane compressors. Due to the large oil content in the compressed air, the quality of snow making was seriously affected; in 2015, Nortek adopted a certain brand of oil-free Scroll compressor, but due to the material and technical problems of the main body of the scroll compressor, there will be a problem that the scroll head is broken. Jinan Company has been actively testing and looking for more suitable air compressors, so that its products can be stably applicable to various environmental conditions, but historical experience shows that Jinan Company faces problems and bottlenecks that only Jinan people know. Atlas Copco talked with it about oil-free scroll compressors in 2016. Since it did not really cut into this technical key at that time, the customer did not have any interest in our compressor, thinking that it was a compressor than the domestic compressor. The imported goods are much more expensive, and no progress has been made in cooperation. After repeated and in-depth exchanges with customers, we found that China's snow guns are still in their infancy, and most manufacturers ignore an important technical problem, that is, not just any air compressor can operate in a low temperature environment. It is for this reason that in the early stage of normal temperature conditions, the working compressor frequently failed during low temperature operation and could not be solved, which brought great trouble to the customer's production and operation, and also had a bad impact on the customer's brand. In 2017, after we fully understood the customer's problems, we recommended the LE5-7Snow piston machine for snow making machines imported from Atlas Copco Italy, which not only solved the long-term problems of customers, but also Gain the trust of Jinan Company, and finally get the opportunity to cooperate! Snow guns are mainly composed of nozzles, snow nuclear devices, compressors, fans, water distribution manifolds, automatic head swing and manual pitching devices, and electrical control systems. It works basically by mimicking the formation process of natural snow. First, the high-pressure air generated by the compressor is sent to the nozzle of the nuclear device, and then the fan motor blows the water into a tiny water mist and ejects it into the air, which is evenly dispersed; then, the nuclear device generates snow cores when the air and water mist reach a certain ratio , the snow core forms snowflakes when it is cooled in the air. Therefore, the nuclear device is the key to snow production, without it, water is produced, and the production and pressure of compressed air in this process can ensure the quantity and quality of snow production.

Because the snow making machine is a product with strong seasonal requirements, it can only make snow when the ambient temperature is lower than 0 degrees. strict requirements. If a snow resort is in a limited low temperature environment, it cannot make snow or the snow making efficiency is relatively low due to the problem of the compressor. How sad it is. The special compressor for Atlas Copco LE5-7Snow snow gun is made of cast aluminum, which is light in weight and easy to install. The motor power is only 3.08KW, which is energy-saving and high-efficiency. Meet all the needs of customers and even exceed customer expectations.

Among the imported snow guns of foreign brands (such as Dimak, Soufage, Snow God and other well-known brands) Atlas Copco has occupied more than 80% of the market. In China, Atlas Copco won the first order from Jinan Machinery for 60 compressors for LE5-7Snow snow guns. Since the air compressors of a certain brand that Nortek had in stock before were not used up, the compressors supporting us in 2017 were only less than half of the number of Nortek snow guns sold in one year. Wu Fenglin, general manager of Nortek, said: In 2018, Nortek's snow guns will all use Atlas Copco's air compressors!

This is the first cooperation between Atlas Copco and Nortec in the snow making project, and it has also brought more reliable and efficient products to the snow making industry, contributing to the sustainable development of China's ice and snow sports industry!
