DMG MORI - “zeroFOG”

In times of dramatic environmental and social change, it is our responsibility to protect and improve both the natural environment and workplace environment by reducing CO2 emissions to create a sustainable society. As a machine tool manufacturer, DMG MORI contributes to society through sustainable value. Machine tools at production facilities create heat and consume coolant during operation, producing oil and emulsion mist that can negatively affect workers health and the machinery's condition. Such mist poses a major problem for long-term production. As a solution to this problem, DMG MORI developed ZeroFog. ZeroFog utilizes a specially designed high-efficiency motor that collects mist with a powerful high-speed fan. A rotating filter removes large particles and fine particles are removed by a final HEPA filter, so the air released is thoroughly cleaned. ZeroFog has four major features. An optimized housing shape and a turbo fan quality built by DMG MORI. The powerful airflow has a high ventilation capacity that keeps harmful mist inside the machine. And a final HEPA filter raises the high mist collection efficiency to over 99.97 percent. The mist collection efficiency was tested on an NTX2500, comparing the performance with and without ZeroFog. Without ZeroFog, a large amount of mist leaked through the conveyor's vent and other openings. With ZeroFog, there was no mist leakage. No mist was leaked even with the door of the machine open. The high-speed rotation of the primary filter collects mist particles larger than one micrometer with high efficiency. Automatic high-pressure air cleaning keeps it maintenance-free. The primary filter requires no cleaning. The final filter is easily exchanged. The machine monitors the amount of clogging and informs you when it's time to change the filter. There's a built-in high-efficiency PM motor and an impeller-shaped fan. Power consumption and CO2 emissions are greatly reduced by more than 35 percent compared to conventional filters. This provides significant savings on long-term running costs after installation. The compact unit has a built-in ductless system that requires no on-site installation work. Effective use of floor space enables improved factory design. The ZeroFog mist collector offers several layout options. Old collectors on existing machines can also be easily replaced with ZeroFog. DMG MORI will continue to pursue technological excellence by providing customers with innovative chip, coolant, and mist solutions.
