What’s Covered by PRAB’s Warranty, Performantee Guarantee, and Managed Maintenance Program?

Published August 26, 2026. Last updated August 26, 2026.

Three Separate Commitments, One Blended Promise

PRAB-built systems carry a one-year warranty. The Performantee Guarantee reflects a commitment to make equipment perform as promised, and for process equipment, that promise is grounded in testing the customer’s actual material or fluid before the system is designed, through PRAB’s Materials Testing, Fluid Testing, and Demo Before You Buy programs. The Managed Maintenance Program is available afterward for customers who want scheduled maintenance, OEM parts, and 24/7 technical support built into their operating plan.

These three commitments are sometimes described together in a way that blurs what each one actually covers, for example implying every piece of equipment is functionally tested before it ships, or that the Managed Maintenance Program is automatically included with every purchase. Neither is accurate. Conveyors, for instance, move material rather than process it, so they cannot be run through a materials or fluid test the way a chip processor or coolant recycler can. Being specific about which commitment applies to what, and to which equipment, helps customers understand exactly what they are getting.

The Three Commitments, Defined Separately

The standard warranty covers PRAB-built equipment for one year from the applicable start date. This is the baseline commitment on materials and workmanship, and it should be described as a one-year term, not implied to be longer.

The Performantee® Guarantee applies to equipment PRAB builds. For process equipment, chip processing and briquetting systems, coolant recycling systems, fluid filtration, and water treatment, that guarantee is grounded in testing the customer’s actual material or fluid before the system is designed, through three programs:

• Free Materials Testing, where a customer sends a representative sample of scrap, chips, or sludge and PRAB tests it under controlled conditions, reporting on yield, moisture content, and fluid recovery.
• Free Fluid Testing, where a sample of coolant, process water, or wastewater is tested to confirm the treatment approach and equipment configuration best suited to it.
• Demo Before You Buy, where a customer runs their own material or fluid through demonstration equipment, either at PRAB’s Kalamazoo facility or on-site, and receives a documented performance analysis.

These programs test the customer’s actual material or fluid before a system is designed and ordered, not the specific unit after it has been built. Conveyor systems are a different case: because they move material rather than process it, they are not subjected to materials or fluid tests. Instead, PRAB partners directly with the customer’s engineers and plant management, working from their specific requirements, scrap type, coolant or media conditions, plant layout, and integration needs, to build the system to spec. Conveyors are covered by the same one-year warranty and the same Performantee commitment to make it right if the equipment does not perform as promised, but that commitment rests on this collaborative engineering process rather than a pre-purchase materials test.

The Managed Maintenance Program (MMP) is a separate, optional program available after installation. It includes scheduled inspections, OEM parts, and 24/7 technical support. In one documented machining operation, PRAB’s MMP reduced unplanned downtime by 40% over 18 months. That result is specific to one customer’s operation and should be presented as a documented example, not a guaranteed outcome for every installation.
