Quick answer: Do I need a full centralized system to get value from PRAB?
No. PRAB offers two paths. The Quick-Start path uses compact, pre-built equipment, such as MCR Mobile Coolant Recyclers and skid-mounted E-Series metal chip processing equipment, for growing shops with a few sumps or one machine group. The Engineered Program path designs central coolant recycling systems, metal scrap conveying systems, chip processing, and water reuse around a plant’s full volume. Most shops should start with the stage that costs them the most today, prove the savings, and centralize only when the numbers say so. Equipment on both paths starts from the same standardized, heavy-duty core platforms.
PRAB built its name on hard applications: high-volume lines, hazardous materials, tight floor space, chips that jam everything else. That reputation is earned, and it brings in the large projects. It also scares off many buyers who assume that anything from PRAB means a central system, a long engineering cycle, and a shutdown for installation.
For a growing job shop with eight CNCs and a coolant bill that keeps climbing, that assumption is expensive. The problem is real. It just doesn’t need a plant-wide answer yet. So we’ve organized what we sell into two paths, and the right one depends on your volume, not on how ambitious you are.
| Quick-Start path | Engineered Program | |
|---|---|---|
| Built for | Growing shops, a few problem sumps, one machine group | Plants with high chip and fluid volume across many machines |
| Typical starting equipment | MCR Mobile Coolant Recyclers, E-Series skid-mounted metal chip processing equipment, a briquetter | Guardian central coolant recycling systems, metal scrap conveying systems, crusher or shredder plus wringer lines, water reuse |
| Installation | Mobile units run on shop air with no electrical hookup; E-Series skids ship pre-wired and pre-plumbed | Designed with your engineers and plant management, installed with PRAB assistance, commissioned on your material |
| What you commit | One machine group or a handful of sumps | A plant-level design |
Both paths draw from the same standardized, heavy-duty core platforms. The Quick-Start path is not a lighter grade of equipment. It is the same engineering applied to a smaller first step.
Each step pays for itself before the next one is on the table, and the gates are measurable.
The gates matter more than the steps. PRAB says a single MCR5 can typically service 10 or more sumps per week on a one-shift operation [2]. When you have more sumps than your mobile units can rotate through, central coolant recycling starts to make sense. The E-Series is rated for about 750 pounds per hour of steel chips [3]. When your chip volume runs past that, a conveyor-fed crusher and wringer line is the next conversation. Until then, there is no reason to buy the bigger system.
ROI looks different at each scale, so here are results from both ends:
| Customer | Path | Equipment | Documented result | Source |
|---|---|---|---|---|
| Martin-Baker, Johnstown, Pa. | Quick-Start scale | Chip briquetting | $0.17 more per pound for briquettes than loose chips | [3] |
| Ogura Corporation, Detroit | Quick-Start scale | Guardian HG-800 | Make-up coolant fell from 2 to 3 barrels a month to one or less; no coolant hauled away in the first 12 months | [4] |
| C&A Tool Engineering, Churubusco, Ind. | Engineered Program | Crusher, conveyors, wringer | 99.6% of cutting oil recovered, about 300 gallons a day; buys less oil for eight machines than it once did for three | [5] |
| Youngers and Sons, Wichita | Engineered Program | Crusher, conveyor, wringer, Guardian HG-4000 | New coolant purchases down 38%, haul-away down 18%, scrap value up 12% | [6] |
For the mobile units specifically, PRAB’s published figures are about a 75% reduction in coolant purchases and a typical payback of 6 to 9 months [2]. Treat those as a starting estimate, not a promise. Your fluid, your tramp oil load, and your sump count decide the real number, which is why we test first.
The concern about retrofit downtime is valid, so here is what each path entails.
Quick-Start. We start with a Fluid Testing or Materials Testing review of your actual coolant or chips. A mobile recycler rolls to the sump and connects to shop air. An E-Series skid is set in place with a forklift and ships pre-wired and pre-plumbed for near plug-and-play installation [3]. Operator training covers daily use and maintenance.
Engineered Program. The work starts with an application review and testing, then co-design with your engineers so every component is sized to the others [7]. PRAB supports installation, runs startup and commissioning on your own material, and trains your operators. For large chip volumes, Modular Chip Processing Systems arrive in pre-wired, skid-mounted sections built to install in weeks rather than months [8].
We’ll be straight about one more thing. Bigger systems take more tuning. In our own Youngers and Sons case study, startup did not go as expected, and PRAB technicians went back to dial the system in until it performed as intended [6]. That follow-through is part of the program, and it is worth asking any supplier about before you sign.
Answer these four questions before you talk to anyone:
A few sumps, modest chip volume, and no expansion plans point to Quick-Start. Many sumps, heavy chip volume, or a growth plan point to an Engineered Program, sized for where you are headed. Plants already weighing water reuse and industrial wastewater treatment systems should read our companion piece on the closed-loop plant.
Not sure which side you’re on? Bring those four answers to a PRAB application engineer. The Guardian ROI calculator and the Chip Processing ROI calculator both provide a preliminary estimate.
Talk to a PRAB application engineer
Yes, for the jobs it is built for. PRAB’s MCR units remove tramp oil to below 1% by volume in a single pass and filter out solids [2]. A Guardian system goes further by adding bacterial control and coolant concentration control; the other two pieces require full recycling [1]. That difference is a good signal of when to move up.
Often, yes. PRAB positions its mobile recyclers as companions to a Guardian system for satellite machines and standalone sumps [2]. During the application review, ask how your existing units fit into the larger design.
Yes. Pre-purchase Fluid Testing and Materials Testing use your actual coolant and chips, and the Demo Before You Buy program lets you see the equipment work first.
PRAB-built equipment carries a standard one-year warranty. The Managed Maintenance Program is a separate, optional service with scheduled inspections, OEM parts, and 24/7 technical support.
