Before DrM, filtration meant dangerous manual work. Founder Dr. Hans Mueller asked a simple question: "There must be a way to do that automatically." That question became DrM Group, founded in Switzerland in 1982. What started as a solution to one problem has grown into engineered systems trusted across chemical processing, mining and metals, oil and gas, food and beverage, battery materials, and pharmaceuticals and biotech. Today, DrM operates from Switzerland, Poland, China, India, Malaysia, and the United States, serving customers in 85+ countries with 4,100+ systems worldwide and 400+ patents.
