Donaldson Co. jumps into Beverage Filtration with LifeTec

It took the Donaldson Co. two years, 40 scientists and millions to build a better mouse trap  –  or a microbe trap, to be exact  —  for the beverage and yogurt manufacturers.

Donaldson, the filtration giant, known for devices that purify air, steam and gases inside factories, recently threw it’s filtration expertise into the world of consumable liquids for the first time.

The result is LifeTec, an ultrafiltration cartridge that captures microbes, bacteria and particles from beverages.  Officials cut the ribbon on a new manufacturing plant in Haan, Germany, earlier this month that will make the product and said it could result in big changes in the market.

LifeTec liquid filters capture dust, bacteria and the cryptosporidium and giardia parasites that could sicken humans and cripple most food makers if the microscopic pests accidentally squirmed into a product.  The LifeTec cartridge is designed for firms that must filter and sterilize water and other liquids to make mineral water, soda, cheese, yogurt, wine, beer and other beverage products.

LifeTec comes in various lengths starting at 10 inches and surpassing 40 inches.  Each cartridge should last one to three months before needing changing, depending on beverage-factory conditions.  While officially launched this month during the plant opening in Germany, LifeTec soon faces a whirlwind of global introductions at trade fairs, including the world’s largest industrial trade show, the Hannover Fair in Germany.

In the U.S., LifeTec will make its debut at the Northwest Food and Beverage Manufacturers Expo in Oregon in January and the Process Expo in Chicago in September 2017.
