HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Nuzhuo has specially designed high-purity nitrogen cryogenic air separation equipment for the automotive tire industry. This equipment adopts advanced low-temperature distillation technology and can stably produce ultra-pure nitrogen gas with a purity of over 99.999%. This technological breakthrough has completely solved the industry pain point of traditional nitrogen gas, which contains trace impurities such as oxygen, water, and dust, causing early oxidation of tire inner tubes and gas sealing layers. In the high-temperature vulcanization process of tires, the “pure nitrogen environment” provided by this equipment enables the rubber molecules to cross-link more uniformly, significantly improving the wear resistance, fatigue resistance, and dynamic heat generation performance of the tire sidewall and tread. Currently, this series of equipment has been applied to the production lines of many well-known semi-rubber radial tires and all-steel load-bearing radial tires both domestically and internationally, helping customers reduce the product defect rate by more than 20%.

As a high-tech enterprise integrating R&D, design, manufacturing and service, Nuzhuo’s core product portfolio features a deep cryogenic air separation equipment as its flagship product, covering all scenarios from small-scale on-site gas production to large-scale centralized gas supply. The core advantages of its products are as follows:

1. Ultra-high purity and stability. The nitrogen production purity of Nuozhu deep cryogenic air separation equipment is stable, the dew point meets the standards, and it complies with the standards of the tire industry. The unique molecular sieve purification system and the explosion-proof design of the main condenser ensure that the nitrogen output of the equipment does not decrease under continuous full-load operation conditions, providing a “zero interruption” gas source guarantee for 24-hour uninterrupted production lines.
2. Extremely energy-efficient and low operating costs. The electricity consumption per unit of gas produced is 12% – 18% lower than that of similar products. The fully automatic load regulation function of the equipment can intelligently match energy consumption according to the real-time gas consumption of users, avoiding energy waste.
3. Modularization and rapid deployment. For tire factory renovation or expansion projects, Nuzhuo has launched containerized/撬-type deep cryogenic air separation units. The factory is pre-assembled and can be connected and used on-site immediately， reducing the installation period by 70%. The occupied area is only 50% of that of traditional equipment， significantly saving valuable production space.
4. Full lifecycle intelligent operation and maintenance. The equipment is equipped with the remote monitoring system independently developed by Nuzhuo. It can monitor the pressure, temperature, liquid level and gas purity inside the tower in real time, automatically issue warnings and generate maintenance work orders. Customers do not need to have full-time experts from the air separation company on site. The Nuzhuo after-sales team can provide 7×24-hour technical support through the cloud, and spare parts can be delivered directly to all over the world.

Thanks to these advantages, Nuzhuo Cryogenic Separation Equipment has not only served the tire industry, but has also been widely applied in fields such as electronics, chemicals, metallurgy, and food preservation.
