About DrM Group
DrM, Dr. Mueller AG is a plant manufacturer specializing in solid-liquid separation and mixing technology, originating in Switzerland. The Group manufactures fully automatic candle filters (FUNDABAC®, CONTIBAC®, STERIBAC®), vibro-mechanical mixers (FUNDAMIX®) and closed single-use systems for biopharma (FUNDALOOP®, FUNDAMIX® SU) from laboratory scale to industrial plants with filter areas up to approximately 200 m². The systems operate as closed pressure filters with filtration, washing, drying and automatic cake discharge in one vessel without rotating seals. Stainless steel, titanium, high-performance plastics and rubber-lined components are used. The further portfolio includes turnkey skid manufacturing including CIP/SIP, FAT, commissioning, GMP qualification, maintenance and spare parts supply. Customers come from pharma and biotech, chemicals, oil and gas, mining and metal processing, electronics, environment, food as well as carbon capture. Core markets are North America, Europe, Asia and Australia.
