Tackling Tramp Oil Contamination with PRAB MCR2 and MCR5
In machining and metalworking facilities, coolant contamination is a silent but costly problem. Hydraulic oil, way lube, and machine oil inevitably migrate into coolant sumps, creating tramp oil contamination. The consequences are immediate: bacterial growth, foul odors, reduced tool life, degraded surface finishes, and coolant that must be replaced rather than recycled. For shops running 10 to 20 CNC sumps, this cycle can represent tens of thousands of dollars annually in wasted coolant purchases and hazardous waste disposal costs.
PRAB’s Mobile Coolant Recycling Systems — the MCR2 and MCR5 — provide a practical, portable solution to this challenge. Designed for machine shops, job shops, and metalworking facilities, these units rejuvenate coolant directly at the machine level. Unlike central Guardian systems, which require significant infrastructure, the MCR2 and MCR5 deliver targeted recycling without plumbing, electrical installation, or downtime.
Both units are built for mobility. Rolling easily from machine to machine on heavy-duty locking casters, they connect to standard shop air and begin working immediately. The process is simple: position the skimmer at the sump, and the system removes tramp oil, separates solids, and returns clean, reusable coolant back to the machine. No electricity is required, no dedicated plumbing is needed, and no installation is necessary. This ease of use ensures that shops can begin realizing benefits from day one.
The MCR2 is ideal for lighter-duty applications and individual machines. It provides effective coolant recycling for smaller operations, ensuring that contamination is addressed before it impacts productivity. The MCR5, by contrast, is engineered for higher-volume sumps and larger facilities. With its greater capacity, it can service multiple machines throughout the week, making it the preferred choice for shops with extensive coolant demands. Both models ship fully assembled and ready to use, minimizing setup time and maximizing immediate impact.
The benefits of these systems extend far beyond cost savings. Cleaner coolant improves machining precision, extends tool life, and ensures consistent surface finishes. By reducing bacterial growth and foul odors, they also create healthier working conditions for employees. Furthermore, recycling coolant rather than replacing it reduces hazardous waste generation, supporting environmental compliance and sustainability initiatives.
Ultimately, the PRAB MCR2 and MCR5 represent more than just equipment — they embody a smarter approach to manufacturing. By addressing the hidden costs of coolant contamination, they empower shops to operate more efficiently, sustainably, and profitably. For facilities seeking a practical, portable solution to coolant management, these mobile recycling systems are investments that deliver immediate and long-term returns.
