Fully Automated Filtration and Mixing Systems. Swiss Engineered to Perform.
Closed filtration and mixing systems
that protect what you make
why choose drm? DrM has designed and built solid-liquid separation and mixing equipment since 1982, starting in Switzerland. Every system follows one principle: keep the product contained, recover as much of it as possible, and prove it at your scale before you commit.
Nothing opens to the room
From feed to discharge the product stays enclosed: no open vessels, no rotating shaft seals, no manual handling. It's what makes toxic, pyrophoric and sterile processes workable in the same equipment.
Less of your product left behind
Residual liquid is recovered rather than discarded thanks to our patented heel filtration, cake discharges dry, and mixing is gentle enough not to damage cells, proteins or crystals. On high-value products, what you keep is the point.
Test it before you commit
Lab and pilot units run on the same operating principle as our production systems, to rent or to buy. You validate the results on your own material before deciding.
Three technologies for
closed solid-liquid processing
Pressure candle filters for solid-liquid separation, vibratory mixers without rotating seals, and single-use systems for sterile processing. Each is available from lab and pilot scale to production.
Candle filters that filter, wash, dry and discharge the cake in one closed vessel. FUNDABAC®, CONTIBAC®, STERIBAC.
Vortex-free vibratory mixing with no rotating shaft seal, gentle enough for cells and crystals. FUNDAMIX® and packaged units.
Closed single-use filtration and mixing for biopharma and high-purity processes: no cleaning validation, no cross-contamination. FUNDALOOP®, FUNDAMIX® SU.
Where our systems run
More than 120 documented applications, from bulk and fine chemicals to mining, electronics, oil and gas, food and pharma. Find your process, see which system fits, and read how others solved it.
Bulk, speciality and fine chemicals, mining and metal processing, electronics, environmental, oil and gas, food and nutrients, pharma.
Pharmaceuticals and cosmetics, chemicals, food and beverage, biochemical processes, agroscience, electronics.
Pharma and biotech, from cell culture to sterile filling, plus contained single-use filtration for chemistry.
From first test
to the last spare part
Every DrM system is engineered for the process it will run. We test your material in our lab and pilot units, design and commission the system around those results, and keep it running with service, upgrades and original parts for the life of the plant.
Feasibility, process and detailed design, automation, skid fabrication, FAT and commissioning, with GMP qualification where required.
Scheduled service, remote and on-site troubleshooting, operator training, upgrades and retrofits.
Genuine parts matched to your system specification, stocked for availability and orderable through the customer webshop or our spare parts department.
