How Much Can Coolant Recycling Systems Actually Save Your Shop?

Published September 9, 2026. Last updated September 9, 2026. Quick Answer Coolant recycling systems recover 95 to 98% of metalworking coolant for reuse by combining particulate filtration, tramp oil separation, and bacterial control in a single system. Facilities typically cut new coolant purchases by 50 to 75% and disposal costs by up to 90%, with return on investment achieved in […]

What Should Be in a Manufacturer’s Metal Scrap Recycling Guide?

Published 9/8/2026. Quick Answer A useful metal scrap recycling guide for a manufacturing plant covers five stages in order: sorting scrap by alloy and form at the machine, conveying it away from production without manual handling, recovering coolant or oil before the metal leaves the building, reducing volume through briquetting when the material justifies it, and negotiating with metal scrap […]

What Systems Are Suitable for Aerospace Alloys and Titanium Chips?

Published September 4, 2026. Last updated September 4, 2026. Quick Answer Aerospace machining shops working with titanium and other exotic alloys need metal chip processing equipment built for the specific hazards and value of those chips. Titanium chips pose a fire risk and contain machining fluid that must be recovered, and the material is valuable enough that shredding and briquetting […]

What Is the Difference Between a Tramp Oil Separator and a Coolant Recycling System?

Published August 13, 2026. Last updated August 13, 2026. Quick Answer A tramp oil separator is a single-purpose device that removes floating or dispersed hydraulic oil and lubricants from coolant. A coolant recycling system is a complete, multi-stage plant that performs oil removal, then adds particulate filtration, concentration control, and bacteria control so the coolant can be pumped back into […]

Is PRAB’s Engineered Complexity a Retrofit Risk or a Managed Investment?

Written by Paul Montgomery, Published July 31, 2026. Last updated July 31, 2026. Quick Answer: No. PRAB’s engineered complexity is managed complexity. Modular, pre-wired skids cut installation from months to weeks, phased rollout sequences limit downtime, in-house lab testing verifies performance before shipment, and proven retrofit methods fit new equipment into existing pits, controls, and production lines. The result is […]

What Is Tramp Oil?

Published July 30, 2026  |  Last updated July 30, 2026 Quick Answer: Tramp oil is unwanted hydrocarbon-based oil, such as way lubricant, hydraulic fluid, or rust-preventive coating, that leaks or migrates into metalworking coolant and washwater. It floats, disperses, or emulsifies in the fluid, where it reduces cooling performance, feeds bacterial growth, shortens tool life, and drives up disposal costs. […]

How Much Can a Coolant Recycling System Save My Manufacturing Facility?

Published July 20, 2026. Last updated July 20, 2026. Quick Answer: A coolant recycling system typically reduces new coolant purchases by 50 to 75 percent and cuts coolant disposal costs by up to 90 percent, while recovering 95 to 98 percent of metalworking coolant for reuse. Most manufacturers see full return on investment within 6 to 18 months, with high-volume […]

Quick Answer How does PRAB handle integration, commissioning, and long-term support for complex systems? PRAB provides system integration and support as well as engineering support from specification through startup, including system layout review, integration coordination […]

Why the Material You Cut Determines the Metal Scrap Handling System You Need

Written by Paul Montgomery, Marketing Leader at PRAB. Reviewed by [Application Engineering, name/title TBD]. Published [Date]. Last updated [Date]. Quick Answer Does the material being machined affect which metal scrap conveyor or chip processing system I need? Yes, significantly. Chip morphology, bulk density, abrasiveness, and coolant affinity vary widely by material. Aluminum produces fine, stringy chips with high coolant retention […]

How Do Chip Wringers Affect Coolant Concentration and Quality Upon Recovery?

Written by Paul Montgomery, Marketing Leader, PRAB, Inc. Reviewed by Mike Proos   |   Published July 2, 2026   |   Last updated July 2, 2026 Quick Answer: A wringer uses centrifugal force to fling cutting fluid off metal chips, recovering fluid that would otherwise leave with the scrap. The recovered fluid is mechanically separated, not chemically cleaned, so it can carry fines […]
