Written by Geicos Group on 11 May, 2026 ![](https://blog.geicosgroup.com/hubfs/geicos-articolo-sgrassaggio.png) In a machine shop or production department, degreasing is never 'just washing.' It is the critical stage that determines whether a component is ready for the next step or becomes scrap. When dealing with complex geometries, blind holes, or millimeter-scale threads, traditional spray methods show their limits: hydrodynamic shadowing prevents the detergent from reaching every nook and cranny, leaving oil residues and swarf exactly where precision is vital. The evolution of industrial degreasing lies in the integration of two key elements: ultrasonic technology and intelligent PLC automation. #### **Consistency is Power: Ultrasonics and Agitation** The secret to achieving a consistent result for every single batch lies in the combination of physical energy and movement. In our solutions, high-frequency ultrasonic technology triggers the cavitation phenomenon, acting at a molecular level to "strip away" contaminants. However, **basket agitation** is what truly makes the difference. By moving the parts during the cycle, we ensure that shockwaves and the detergent solution reach every single surface, flushing out the air bubbles that often remain trapped in blind holes. The result is a level of uniform degreasing that no manual intervention could ever replicate with the same consistency. #### **Reducing Downtime with PLC Control** In production, time is the most expensive resource. Delegating the washing process to an operator means taking precious hours away from higher value-added tasks. Thanks to PLC control, the Geicos process becomes fully autonomous: - **Repeatability:** Once the program is set, the machine performs the same perfect cycle every time, eliminating human error. - **Workflow Optimization:** The operator only needs to load the basket and start the cycle. While the machine is running, they can focus on maintenance or CNC production. - **Parameter Management:** Temperature and timings are constantly monitored, ensuring that the energy from both the heaters and the ultrasonics is used with maximum efficiency. #### **Smart Maintenance and Recirculation** Advanced degreasing also means managing the quality of the cleaning bath. If the fluid is saturated with oil, the parts will come out with streaks or smudges. Integrating systems such as **oil skimmers** and fluid recirculation allows the solution to stay clean for much longer. This translates into less machine downtime for water changes and, above all, a drastic reduction in waste disposal costs. ![sgrassaggio-industriale](https://blog.geicosgroup.com/hs-fs/hubfs/sgrassaggio-industriale.png?width=779&height=584&name=sgrassaggio-industriale.png) ### **The Geicos Solution: The UG-300** The Geicos solution engineered to meet these challenges is the [**UG-300 – 300L Ultrasonic Tank**](https://store.geicosgroup.com/en/collections/ultrasonic-parts-washers/products/ug-300-ultrasound-machine300l). Our ultrasonic parts washers are professional-grade stainless steel tanks designed for the industrial cleaning of mechanical components and precision small parts. While highly specialized for the automotive sector, they are also perfectly suited for marine, aerospace, steel, MRO (Maintenance, Repair, and Overhaul), and numerous other applications. Robust, reliable, and built for 24/7 continuous operation, the UG-300 fully automates the washing process. Its high-frequency ultrasonic technology—combined with powerful heating systems, basket agitation, and PLC control—ensures deep, uniform cleaning even on complex geometries, drastically reducing downtime and manual labor. Thanks to a range of tank capacity configurations and the option to integrate features like oil skimmers, fluid recirculation, and dedicated safety systems, the UG-300 is the ideal solution for small parts, varied mechanical components, and automotive hardware. The 300-liter version is specifically designed for heavy-duty workloads and high-volume production cycles that demand maximum durability and top-tier performance. #### **Facing a unique degreasing challenge in your department?** [Get in touch with the Geicos technical team](https://www.geicosgroup.com/contacts/contacts/)**.** Together, we will analyze your part geometries to engineer the perfect cleaning cycle.
