Fluid Recycling Equipment uses a variety of technologies to separate solid matter and contaminants from used metalworking fluids. The used fluids typically come directly from a machining sump or are recovered from metal scrap processing equipment. Systems are designed for oil/water separation, fluid filtration, bacteria elimination and coolant concentration control. After processing, the coolant or oil can be reused, drastically reducing new fluid purchases and improving working conditions.

The perfect fluid recycling system depends on a variety of factors including volume per hour, coolant type, contaminants, fluid filtration (micron) level and desired level of automation. Our team works with each customer on an individual basis, collecting vital application data and putting together the best solution to meet your specific objectives and requirements.
