What AT-OS does

AT-OS S.R.L. is an Italian privately held medical-device manufacturer founded in 1996 and headquartered in Colognola ai Colli (Verona), Italy. The company specializes exclusively in washing and thermal disinfection equipment for healthcare environments, with a portfolio built around two core machine families: the AF2 line of front-loading bedpan washer-disinfectors and the AWD655 line of instrument washer-disinfectors offered in capacities from 2 to 15 DIN trays and variants for medical, dental, and laboratory use. All products are designed to comply with EN ISO 15883 and the EU MDR (Regulation 2017/745), with additional UL certification for the US/Canada and DVGW plumbing certification in Europe.

The company's core competency extends beyond individual machines into a complete CSSD (Central Sterile Services Department) ecosystem. This includes the DTS (Dynamic Transfer System) for automated loading and unloading of trolleys, the Ebox digital traceability platform for cycle documentation and remote monitoring, AP1/AP2 pass-through windows for clean/dirty area separation, a range of stainless steel furniture for CSSDs and operating theatres, specialized washing trolleys and baskets (including for Intuitive Surgical's da Vinci robotic instruments), and the AT-CLEAR line of professional detergents. Revenue is generated through direct enterprise field sales of hardware, recurring consumables (chemicals, spare parts shipped within 12–24 hours from a LEAN warehouse), paid after-sales service, and training delivered via the AT-OS Academy.

AT-OS serves hospitals, medical centers, nursing homes, dental clinics, veterinary clinics, and analytical laboratories across more than 90 countries, with active marketing at international trade shows (Arab Health, WFHSS, IDS, WHX Dubai). Distribution is direct, quote-based, and led by an in-house commercial team supported by authorized service centers in Italy. The company is led by founder and CEO Paolo Lorenzini and operates with 51–100 employees, reporting nearly 29,000 machines installed worldwide.
