Oil Sump Cleaner (Coolant Filtration Machine)

Still cleaning the coolant tank the traditional way? The RTES metal cutting fluid filtration system removes the entire sludge from the coolant tank without taking a shutdown. By utilizing constant filtration, machine tool coolant tanks remain clean, extending coolant life — which lowers disposal costs, improves tool life, and can improve part quality.

Each coolant reacts differently with contaminants. Some coolants reject tramp oil altogether, creating 'free oil' that floats on the sump surface and can be cleared with an oil skimmer; others emulsify tramp oil, requiring a tramp oil separator, coalescer, or centrifuge — and a solution that worked can suddenly stop working as the chemistry shifts.

Left unremoved, metal cutting debris turns sumps into a breeding ground for bacteria, which degrades fluid chemistry: bacteria eat the emulsifiers that stabilize water-based coolants, and feed on corrosion inhibitors while excreting organic acids, salts and hydrogen sulfide — all themselves corrosive.
