Many companies view the regular replacement of coolant as a normal part of their production process. But is this really necessary?

Often, the real problem isn’t the coolant itself, but rather the increasing contamination from chips, grinding slurry, and fine particles. As a result, the coolant must be replaced sooner than necessary.

This means:

✔️ Higher costs for fresh cooling lubricants
✔️ Rising disposal costs
✔️ Increased maintenance and cleaning efforts
✔️ Additional machine downtime

However, the service life of cooling lubricants can be significantly extended through continuous filtration tailored to the specific application. Clean process fluids not only ensure lower operating costs but also stable manufacturing processes and greater process reliability.

This is exactly where LIQUI Filter GmbH’s coolant cleaning systems come into play. Whether for a single machine, a production cell, or a centralized coolant supply system—our portfolio offers the right solution for a wide variety of applications to keep coolants circulating efficiently.

After all, the goal isn’t to change coolants more frequently—it’s to maximize their service life in a cost-effective way.

How often do you change your cooling lubricants—because it’s truly necessary, and not because contamination forces you to?
