Coolant is vital for precision machining, but it also creates recurring costs for operations.
As fluids degrade, manufacturers face increased tool wear, reduced quality, high disposal fees, and the excessive costs of increased fluid top-offs. This makes coolant the hidden cost driver in metalworking, increasing the amount and type of fluid expenses operations must handle.
Fortunately, integrating fluid separation and filtration systems mitigates these losses, keeping coolant stable, clean, and reusable for years, thereby cutting new fluid costs and improving your bottom line.
PRAB® fluid filtration and coolant recycling systems reclaim and recondition spent coolants in the plant, delivering measurable savings and making recycling an essential strategy for modern manufacturing.

Several factors, notably the degradation cycle, directly contribute to increased coolant expenses.
The key to stopping the degradation cycle before it starts is through closed-loop filtration and recycling.
Modular systems from PRAB® combine particulate removal, tramp-oil separation, and bacteria control for reliable, long-term performance. The systems’ coolant recycling technologies encompass:
