MKR Metzger GmbH

MKR Metzger GmbH, headquartered in Monheim, Bavaria, Germany, manufactures industrial wastewater treatment and process water recycling systems under the tagline of innovative recycling of process media. The company's evaporator line spans twelve models from the ET 50 through the ET 2000 (likely denoting liters per hour of evaporation capacity), topped by the ET MaXx ZLD for zero liquid discharge applications. Mechanical Vapor Recompression (MVR) technology drives these systems, recompressing generated vapor as heating energy to cut energy consumption while maintaining stable continuous operation. Complementing the evaporators, MKR offers the UC series ultrafiltration units (UC 1, UC 2, UC 4) for membrane-based filtration, SF series vacuum and filter carts (SF 250 through SF 1000) for mobile on-site processing, TB series foreign oil separators (TB 250, TB 250 VA in stainless steel, and TM 450 UV with ultraviolet disinfection), and both disc-stack and drum centrifuges for oil and particle separation. The company provides remote monitoring, worldwide spare parts, and system hotline support. MKR systems are deployed across aviation and MRO, metalworking, automotive, chemicals and pharmaceuticals, electronics, energy, electroplating, heat treatment, and parts cleaning industries. A new production hall was under construction in late 2025 to expand manufacturing capacity.
