Parts Cleaning Systems for the MRO Industry
Smarter Cleaning for Maintenance, Repair, and Operations
Every minute of downtime costs productivity. In maintenance and repair environments, clean parts mean reliable performance, fewer failures, and safer operations. Better Engineering’s automatic parts washers give MRO teams the tools to maintain critical components consistently and with confidence. Built from industrial-grade stainless steel and backed by six decades of engineering expertise, our systems are designed to clean better, last longer, and simplify your maintenance workflow.
TRUSTED BY Manufacturers
Leading maintenance and repair facilities rely on Better Engineering systems to keep operations running efficiently. From aviation to heavy equipment and rail/transit maintenance, our systems are engineered to clean, degrease, and restore parts with precision and repeatability.
Cleaning Solutions for Every MRO Environment
Maintenance and repair operations deal with a diverse range of parts, from heavy-duty mechanical assemblies to precision electrical components. Each requires a tailored cleaning approach to restore functionality and extend service life. Better Engineering systems are engineered to handle these variations with configurable spray pressure, temperature, filtration, and chemical dosing options.
Mechanical Components
Better Engineering’s MRO automatic parts washers are engineered to clean remanufactured engine blocks, gearboxes, bearings, and fasteners with the power and precision needed to handle heavy contamination. Each large parts washing system combines high-pressure spray manifolds, heated aqueous solutions, and advanced filtration to remove carbon, oil, and metal debris from complex internal passages. Vertical sealless pumps deliver consistent flow and impingement, while optional immersion and ultrasonic stages tackle blind holes and coolant galleries. The result is a thoroughly cleaned, inspection-ready component that meets the strict standards of remanufacturing and rebuild operations.
Hydraulic and Pneumatic Parts
Better Engineering’s MRO industrial parts washers are designed to clean hydraulic and pneumatic components such as valves, pumps, and actuators with precision and reliability. Our systems effectively remove hydraulic fluids, lubricants, and particulates from internal and external surfaces using heated aqueous sprays and multi-stage filtration. Each washer is engineered with strict fluid segregation between wash and rinse stages to prevent cross-contamination and maintain fluid purity. The result is dependable, contamination-free performance for every component after cleaning and reassembly.
Electrical and Electronic Housings
Better Engineering’s MRO systems are designed to safely clean electrical housings and rotating components, including traction motors, armatures, sensor housings, and control enclosures, without damaging sensitive seals, windings, or coatings. Using low-pressure spray technology and adjustable heat profiles, our washers remove oils, carbon dust, and process residues while maintaining component integrity. Optional filtered air or vacuum drying ensures complete moisture removal for electrical reliability. The result is precise, residue-free cleaning that restores motors and electrical assemblies to peak operational performance.
Structural and Support Hardware
Better Engineering’s systems are engineered to clean large structural support hardware found in demanding applications such as rail, transit, and heavy equipment. From railway bogies and trucks to frames, couplers, and bearing housings, our washers remove oil, grease, brake dust, and carbon buildup from heavy, load-bearing assemblies. Each system is designed for high-impact cleaning, efficient material handling, and complete coverage of complex geometries, ensuring critical components are restored to safe, reliable operating conditions.
MRO and Transit Applications
Better Engineering’s industrial parts cleaning equipment serves the most demanding environments in the MRO transit industry, ensuring reliability, longevity, and efficiency across every sector.

frequently asked questions
Better Engineering industrial parts washers clean a wide range of components, including engine blocks, housings, gearboxes, transmissions, motors, armatures, bogies, trucks, fasteners, pumps, valves, actuators, and many others.
Better Engineering’s MRO industrial parts washers are engineered to minimize maintenance downtime and keep operations running continuously. Automated wash, rinse, and dry cycles replace manual cleaning, reducing turnaround time between rebuild stages. Quick-access panels, clean-out doors, and tool-free filter changes make routine maintenance fast and simple, while robust oil separation and multi-stage filtration extend bath life and reduce service frequency. Built with vertical sealless pumps and stainless steel construction, these parts washers deliver reliable performance with fewer interruptions and lower overall maintenance costs.
Absolutely. Each system can integrate with conveyors, lift tables, or automated material handling for seamless operation within your facility.
Yes. These systems are engineered to remove heavy soils from large and complex rail components, including traction motors, armatures, wheelsets, axles, bearings, couplers, and brake assemblies. Spray manifolds, part fixtures, and flow paths are designed to reach critical areas, such as commutators, core stacks, and bearing surfaces, ensuring thorough and repeatable cleaning.
Automated cleaning systems provide consistent, repeatable results by standardizing wash cycles, temperature, pressure, and detergent concentration. Automation reduces reliance on manual scrubbing, which lowers labor hours, minimizes operator exposure to chemicals, and improves overall safety. By maintaining fixed cycle times and allowing for continuous loading or 24/7 operation, automated systems also support higher throughput and more predictable maintenance scheduling.
Yes. Rail and transit operations often require continuous or near-continuous cleaning to support overhaul cycles, and these systems are built for heavy-duty, long-duration performance. Robust pumps, high-capacity filtration, and industrial-grade materials support 24/7 operation with minimal performance degradation over time.
Aqueous systems use heated, recirculated alkaline detergents combined with high-pressure, high-volume spray delivery to break down and remove grease, lubricants, carbon dust, and packed-on debris. Integrated filtration, such as oil coalescers, bag filters, and sludge conveyors, continuously removes contaminants from the solution, maintaining cleaning efficiency and extending bath life.
Systems can be tailored to the unique shapes, weights, and contamination profiles of rail components. Customization options include targeted spray manifolds for traction motors and armatures, specialized fixtures and baskets for oversized components, reinforced load capacities, enhanced filtration packages, adjustable tank sizes, and automated material-handling or loading systems. These configurations ensure optimal cleaning performance and seamless integration into existing maintenance workflows.
