Ozone is revolutionizing the way commercial laundry systems operate. From hotels and hospitals to correctional facilities and nursing homes, more facilities are turning to ozone laundry systems as a smart alternative to traditional hot water and chemical-heavy processes. Not only does ozone save energy and reduce operating costs, but it also improves laundry hygiene and extends the life of linens and towels.
How Ozone Laundry Works
Ozone (O₃) is a powerful oxidizer and natural disinfectant. In a commercial laundry application, ozone is introduced into the washing process in two primary ways:
- Dissolved in Cold Water
Ozone gas is injected into the wash water using a venturi injector, where it dissolves and begins oxidizing organic material, soils, and pathogens. - Injected Directly into the Washer
Ozone is also introduced in gaseous form inside the washer, further enhancing disinfection and cleaning effectiveness during the wash cycle.
Despite ozone’s strength, detergents are still used—just in smaller amounts, and only cold water is required. In many cases, the final rinse step can be reduced or eliminated entirely, cutting water consumption significantly.
Key Benefits of Ozone Laundry Systems
- No Hot Water Required
By replacing hot water with ozonated cold water, facilities save significantly on energy costs. This also helps meet sustainability goals. - Powerful Disinfection
Ozone effectively kills bacteria, viruses, and mold, reducing the risk of cross-contamination and illness. This is especially important in healthcare, hospitality, and institutional settings. - Extended Linen Life
With reduced detergent use and no exposure to high water temperatures, towels and linens experience less wear, maintaining their quality and durability over time. - Lower Chemical Usage
Ozone allows for the use of milder detergents at lower doses, which is better for both the environment and the health of laundry staff. - Reduced Water Use
In some systems, ozone enables the elimination of a rinse cycle, further conserving water and reducing wastewater treatment demands.
Real-World Example: Ozone Laundry Setup
In one of our installations, a VMUS-4 Wall-Mount Ozone Generator paired with a VMD-8 Air Dryer is used to supply ozone to two washers (operating one at a time). Ozone is injected into the water using a Mazzei Venturi Injector, with a bypass valve to fine-tune vacuum and ozone draw for optimal dissolution.
This system allows for:
- Simple, automated ozone delivery
- Precise ozone mixing via venturi injector
- Flexible use across multiple machines
This configuration is compact, cost-effective, and scalable depending on laundry volume and facility needs.
