Centrifugal separators from Alfa Laval rotate at up to 10,000rpm to separate metal fines and tramp oils down to 1µ in size from cutting fluids and other industrial fluids.

Once contaminated with metal fines, swarf and tramp oils, this type of fluid has to be cleaned or replaced. This latter option can prove expensive, since each time tanks are replenished a machine shop is paying not just for the new coolant, but for the expense involved in disposing of the contaminated fluid. A machine shop with five machine tools that replenishes the sumps four times annually can spend in excess of £14,000.

Alternatively, savings in both money and time can be made if the coolant is recycled. Alfa Laval centrifugal separators range from small, mobile units to large systems and effectively purify lubricating and cutting fluids, extending their lives almost indefinitely.

In doing so, they remove major problems like reduced cutting efficiency, bacterial growth in the coolant tank and potential health issues such as dermatitis and other skin diseases.
