Ozone for Commercial Laundry Systems

Ozone technology is widely used in commercial laundry operations to improve washing performance, reduce energy consumption, and support more efficient laundry processes. By introducing dissolved ozone into the wash water, commercial laundry systems can enhance oxidation during the wash cycle while reducing reliance on hot water and excessive chemical usage.
Today, ozone laundry systems are commonly used in hotels, hospitals, healthcare facilities, linen services, industrial laundries, and uniform rental operations.

This guide explains how ozone is used in commercial laundry systems, its benefits, and the factors that influence system performance.

How Ozone Laundry Systems Work

Commercial ozone laundry systems generate ozone from oxygen and dissolve it into the incoming wash water. The basic process includes:

• Ozone generation
• Ozone injection into water
• Ozone dissolution and mixing
• Oxidation during the wash cycle

Once dissolved, ozone reacts with organic contaminants, odor-causing compounds, and other oxidizable substances present in the laundry load. After treatment, ozone naturally decomposes back into oxygen.

Benefits of Ozone in Commercial Laundry

• • Reduced Energy Consumption

One of the primary advantages of ozone laundry systems is the ability to reduce hot water requirements. Because ozone remains more stable in cold water and provides strong oxidation performance, many facilities can significantly reduce water heating demands.

• • Reduced Chemical Consumption

Ozone can supplement traditional wash chemistry by helping oxidize contaminants during the wash cycle. Many facilities report reductions in detergent, bleach, and specialty chemical usage depending on the application and wash program design.

• • Improved Odor Control

Ozone helps oxidize odour-causing compounds that can remain trapped in fabrics. This can be particularly beneficial in:

• • • Hospitality laundries
    • Healthcare facilities
    • Sports uniforms
    • Industrial workwear
  • Improved Wash Water Quality

Ozone treatment can help reduce organic contamination during the wash process and support cleaner wash water.

• Extended Linen Life

Lower washing temperatures may reduce thermal stress on fabrics and help extend the life of textiles in some applications.

Why Ozone Concentration Matters

Not all ozone laundry systems deliver the same performance.

The effectiveness of ozone treatment depends on:

• Ozone concentration
• Ozone dissolution efficiency
• Contact time
• Water temperature
• Wash cycle design

Systems producing higher dissolved ozone concentrations generally provide more effective oxidation during the wash cycle.

Proper system sizing is critical to achieving consistent laundry performance.

Common Commercial Laundry Applications

Ozone laundry systems are used in a wide range of commercial and industrial facilities, including:

• Hotels
• Hospitals
• Healthcare facilities
• Long-term care centers
• Linen service companies
• Uniform rental operations
• Industrial laundries
• Sports facilities
• Hospitality services

Common Mistakes When Designing Ozone Laundry Systems

Several design issues can reduce the effectiveness of ozone systems.
Common mistakes include:

• Undersized ozone generators
• Low ozone concentration systems
• Poor ozone injection design
• Inadequate dissolution efficiency
• Insufficient contact time
• Improper system sizing

Proper engineering and ozone transfer design are critical for achieving reliable laundry performance.
