Danfoss intelligent Air Purger IPS 8 lower energy costs with maximum system performance in OB Beer Brewery
As Korea’s leading beer company, OB Beer accounts for more
than 80% of Korea's beer exports with more than 24 types of
beer exported to more than 24 countries around the world.
Founded in 1933, OB Beer produces high-quality beer at three
major breweries. Recently, the company replaced its manual air
purger in their breweries with the intelligent Danfoss IPS 8,
which now provides lower energy costs while maintaining
maximum system performance.
