PRAB Oil Recycling Systems (ORS) are engineered to remove suspended solids and moisture that degrade industrial oils and shorten equipment life. By continuously polishing contaminated oils and returning them to process, the ORS helps manufacturers cut fluid replacement costs, reduce unplanned downtime, and maintain consistent lubrication quality across the plant.
Designed for centralized use in metalworking, machining, die casting, stamping, and other heavy-duty applications, PRAB’s ORS runs automatically 24/7, ensuring clean, dry oil with minimal labor and maintenance.
The ORS continuously circulates oil through multiple stages of separation and fine filtration. Contaminants—including ferrous metal fines, non-ferrous particulates, and free/emulsified moisture—are removed and discharged to a central waste collection point. Clean oil is routed back to the system’s tank for repeated passes until optimal clarity and dryness are achieved.
This multi-pass approach ensures stable lubrication, improved equipment reliability, and longer oil life—often supporting thousands of hours of uninterrupted operation.
Depending on the required cleanliness target, PRAB can configure the ORS with one or more of the following high-efficiency separation technologies:
Removes ferrous particulate down to 10 microns, protecting downstream equipment and extending filter media life.
Removes ferrous and non-ferrous solids down to 5–10 microns, ideal for high-solid-load applications.
Delivers precision separation of particulate down to 1 micron and removes free and emulsified moisture.
Final filtration stage to remove particulate 1–25 microns and remaining moisture for high-clarity oil.
This modular design allows PRAB to engineer a system matched to each facility’s oil type, contamination load, and quality requirements.
The ORS is fully automated and designed for continuous operation, minimizing manual intervention.
Oil circulates from the dirty tank through the filtration components, then overflows from the clean tank back to the dirty tank for repeated polishing passes. This ensures consistent cleanliness while reducing maintenance time and preventing production interruptions.
PRAB offers multiple ORS configurations to support small, medium, and large centralized oil tanks. Systems can be integrated with new or existing plant layouts and customized to meet specific flow rates, cleanliness goals, and automation needs.
Extend oil life 2–5× by removing damaging particulates and moisture
Reduce unplanned downtime caused by abrasive wear, varnish formation, and lubrication failures
Improve machine performance and tool life with consistently clean, moisture-free oil
Lower disposal and new oil purchasing costs through continuous recycling
Minimize labor requirements with fully automated, 24/7 operation
Support ISO 14001 and sustainability goals by cutting waste volumes and resource use
Compatible with large centralized tanks and multi-machine systems
PRAB’s Oil Recycling System (ORS) is a centralized, automated solution that removes particulates and moisture to extend the lifespan of industrial oils. The system continuously recirculates oil through multiple filtration technologies until the target cleanliness level is achieved.
Dirty oil enters the system from the plant’s central tank.
Suspended solids and moisture are removed using magnetic, centrifugal, and/or polishing filtration technologies.
Separated contaminants are discharged to a central collection point for easy handling.
Clean oil overflows to the clean tank, then returns automatically to the dirty tank for repeated multi-pass polishing.
24/7 automated operation maintains optimum oil quality with minimal labor.
