3S combines modern technology and deep expertise to build professional industrial laundry machines—and to deliver a different kind of clean. As both a manufacturer and a turnkey partner, we design, engineer, and commission complete laundry solutions for hospitals, hotels, and central laundries. Every machine is built around human-centered ergonomics, premium components, and control logic that raises wash quality while reducing water and energy consumption.

Our standout innovation is a patented nanoparticle system that helps prevent and control textile-borne infections, elevating hygiene in high-stakes environments without compromising throughput or fabric care. This focus on safety and efficiency reflects our broader mission: make industrial laundry smarter, cleaner, and more economical for our customers.

The 3S team brings uncommon domain depth. From 2006 to 2017 we worked in Hi-Tech medical equipment, gaining first-hand insight into healthcare standards and challenges. Since 2017 we’ve advised on the design, implementation, and commissioning of more than 50 large laundry projects across Iran. The concept behind 3S matured in 2019 through GIZ’s “Fit for Partnership with German Companies” program in Aachen, and the company was formally established in 2023 to industrialize that vision at home.

Today, we pair advanced engineering with responsive after-sales service, training, and lifecycle support—so your operation runs reliably from day one and keeps performing for years.
