What PASSAPONTI metal cleaning technology does

PASSAPONTI metal cleaning technology srl is a privately held Italian industrial equipment manufacturer founded in 1966 and headquartered in Scandicci, in the Florence metropolitan area. The company designs and produces industrial washing machines, multistage automatic cleaning plants, and ancillary systems for metal parts used in automotive, aerospace, railway, oil & gas, mechanical, and defense/MRO operations. Its product portfolio spans more than 200 machine models across immersion cleaning (AGI-DIP®, ROTO-DRUM®, Multi-Dip®), spray cleaning (ROTO-JET®, ROTO-CAB®, Mobil-Jet®, ROTO-SPRAY®), tunnel and conveyor systems (Linear Tunnels®, Carosel®, Reciprocating Tunnels®), and ultrasonic cleaning (LAB-SONIC®, DIP-SONIC®), together with add-on modules such as OILNET® coalescers, MICRONET® filtration, RETEN-MIST® and VAPOR-MIST® vapor handling, DI&Dry® zero-liquid-discharge water recovery, and the Clean-Bay® cleanliness verification platform. The underlying technology integrates industrial chemistry (cleaning agents reacting with contaminants) and mechanical engineering (machine dynamics optimizing the cleaning process), with proprietary innovations including AGI-DIP HYPER anti-redeposition immersion, piezoelectric ultrasonic transducers operating between 25 kHz and 160 kHz with over 90% energy efficiency, and Clean-Bay verification aligned to ISO 16232 and ISO 18413.

The company sells capital equipment, proprietary chemical detergents, consultancy and validation services (ISO cleanliness testing, contaminant analysis, personnel training), and a licensing/technology transfer program to international partners, generating revenue across one-time hardware sales, recurring consumables, and services. Distribution is enterprise-direct with a "Fast Consultant Service" for problem intake, supported by Italian, German, and Russian localized websites. Strategic positioning is anchored by Convenorship of CEN TC271 Working Group 1, which developed the EN 12921.1-4 safety standards for cleaning machines, and active participation in ISO working groups for precision cleaning of hydraulic and automotive components. The firm is also an EU- and Tuscany Region-funded R&D partner of the University of Florence, producing sustainability-oriented innovations such as DI&Dry.

Named enterprise customers include Stellantis, Ferrari (since 1978), Delphi Automotive Systems (since 1996), General Motors Powertrain, ZF Lenksysteme, VW-Audi, FIAT, MTU Aero Engines (since 2001), UTC Aerospace Systems, Iberia Aerospace, Pressofusione Saccense, and Saginaw Steering (since 1978), with installations spanning Italy, Germany, Spain, the USA, Poland, and Mexico.
