Coolant Recycling Systems Minimize Fluid Disposal

HydroFlow coolant recycling systems from Eriez are designed to recycle any water-miscible fluid. They offer low maintenance and unattended operation in addition to minimizing or eliminating disposal, reducing usage of the fluid concentrate, and improving plant profitability and productivity. Four systems are available, ranging in size from small to large.

The CRS 120SS unit features a side-by-side tank design and is equipped with a coalescer for removing free and mechanically mixed tramp oils. The system can also be equipped or retrofitted with a high-speed centrifuge which removes free-floating and mechanically mixed tramp oil, as well as bacteria-feeding tramp oils that have been partially emulsified into the metalworking fluids.

The CRS 120ST model offers a stacked tank design to conserve floor space. With its high-speed centrifuge, the unit enables complete recycling of virtually any metalworking coolant. Only one pass through the system is necessary to remove tramp oils, particulate matter and a substantial portion of the bacterial population, the company says.

The CRS 300ST unit provides a larger centrifuge for higher processing rates and greater flexibility for adding optional equipment. The CRS 300ST series also offers an optional dual-product design, the CRS 200/200 ST, which features two dirty and two clean tanks for facilities using two metalworking fluids.

Finally, the CRS 300SS model is a complete, full-capability recycling system for medium-to-large sized plants operating machine tools with individual coolant sumps. According to Eriez, the CRS 300SS model can meet the recycling requirements of facilities with as much as 10,000 gallons of total sump capacity.
