Jindawei Group is the world's leading supplier of nutritional supplements, operating four production plants in Xiamen and Hohhot, Inner Mongolia. To meet their demand for compressed air during the fermentation process, Atlas Copco's sales and technical service teams recommended 16 ZA 6G-300 low-pressure oil-free screw compressors to keep the Hohhot production line running smoothly.

"Our main products include coenzyme Q10, DHA and ARA for milk and nutritional health products, and fermentation is one of the most important steps in the production process of these key additives," said Mr. Jiang, the site manager of the Hohhot production base.

"With 16 fermenters connected to the production line, pre-filters, water vapor separators and other equipment can cause pressure drops and air leaks," said Yang Mingzhe, senior sales engineer at Atlas Copco, "in order to keep the incoming fermentation The air pressure in the tank is 2-2.5 bar, and considering other production processes and conditions, we set the front input pressure to 3 bar to keep the fermentation line running smoothly.”

The purity of the compressed air is critical to the fermentation process. “Air purity is very important because compressed air is in direct contact with the fermentation process. Even a small amount of oil contamination can destroy the flora, contaminate the final product and endanger the health of consumers. Therefore, absolutely oil-free compressed air is our focus.” Jiang stressed.

As the first manufacturer to be ISO 8573-1 Class 0 (2010) certified, Atlas Copco ZA compressors set a new standard for 100% air purity. Class 0 means no risk of contamination, no risk of damaged or unsafe products, and no risk of loss due to downtime.

ZA compressors are also synonymous with durability and reliability. They integrate Atlas Copco's proven screw technology, stainless steel coolers, AGMA A4/DIN 5 gears, and state-of-the-art electric systems, all of which contribute to their reliability.

Mr Jiang added: "Atlas Copco is the technology leader in today's oil-free air compressors, which has guaranteed us many years of uninterrupted and safe production."
