Notably, ozone assists in soil breakdown while enabling detergents to lift and remove grime, providing customers with peace of mind that their clothing is free from contaminants, including the notorious COVID-19 virus.

How is Ozone Injected into the Laundry?

Ozone is introduced into washing machines primarily through two methods. The first, which is preferred for its effectiveness, involves direct injection of ozone into the washing machine's sump, mixing it with water and laundry. We maintain the ozone concentration at approximately one part per million, ensuring safe and effective disinfection. The second method, utilizing a Venturi system, dissolves ozone into water, which is then introduced into the wash cycle. Both methods are efficient, the choice depending on practicality and preference, with direct injection favored for its reliability.

The Environmental Impact

One of ozone's remarkable characteristics is that it leaves no harmful byproducts, ultimately reverting back to oxygen (O₂). This unique feature ensures that no chemical residues are left behind, and even when ozone-infused water is drained, it helps combat foul odors in sewage systems, providing additional benefits for laundromats and facilities where unpleasant smells are a concern.

Q: WILL OZONE FOR COMMERCIAL LAUNDRIES WORK ON COLORED LINENS?

Ozone, being an oxidizing agent, can potentially fade organic dyes. However, it's essential to recognize that the coloring of all commercially washed and dried clothing may fade over time.

Q: WILL OZONE LAUNDRY SYSTEMS HURT MY WASHERS?

Gas-phase ozone is more aggressive than dissolved ozone. Systems that inject ozone directly can occasionally cause damage to the washer. One notable manufacturer has voided warranties on direct ozone systems, but indirect ozone systems have not been associated with any cases of washer damage over the past fifteen years. Aqueous ozone effectively cleans clothing while also neutralizing odor-causing bacteria within laundry machines.

Q: WILL OZONE HURT MY LINEN?

Tests conducted by the Textile Rental Services Association (TRSA) indicated that ozone can weaken linen when strong ozone gas is applied directly. However, our testing shows that indirect ozone, when compared to traditional hot water processes, improves textile strength. Some clients have even reported halving their linen replacement costs, with reductions of 20 to 30% being more common.

Q: WILL I NEED TO VENT MY WASHERS?

In instances where direct inject ozone systems are used, it may be necessary to ventilate the laundry in response to high ozone levels. This is not an issue for indirect systems as long as the proper degassing occurs before ozone enters the washer.

Q: WHAT'S THE DIFFERENCE BETWEEN INDIRECT AND DIRECT OZONE SYSTEMS?

Indirect ozone systems (aqueous ozone) dissolve ozone in water before it reaches the washers, eliminating any undissolved ozone and maintaining proper ozone levels. These systems provide ease of application across various washer sizes. Direct inject systems achieve success with smaller washer loads (up to 50 lbs), but face challenges in delivering adequate ozone levels for larger washers.

Q: WHAT ARE THE MAINTENANCE REQUIREMENTS FOR AN AQUEOUS OZONE LAUNDRY SYSTEM?

Keeping equipment clean and dry is critical in maintaining an ozone laundry system. The laundry environment presents unique challenges, and we continually source robust vendor partnerships to ensure the longevity of our components.

Q: WHAT ARE THE DOWNSIDES OF OZONE FOR COMMERCIAL LAUNDRY?

One challenge is encouraging staff to adapt their practices. Even small changes can be difficult to implement long-term, requiring thorough training and open-minded attitudes among laundry personnel and management. Having a proactive chemical representative and a reliable ozone laundry supplier committed to your ongoing success is critical.

Furthermore, ensuring you have long-term support is essential, as you may encounter issues unrelated to ozone technology, despite it being a new aspect. An alarming number of ozone systems previously installed by various suppliers have ceased operation, indicating unmet promises and wasted investments.

Q: WHAT ABOUT OZONE AND PERSONAL CLOTHES?

Our experience applying ozone in healthcare settings where personal clothing is laundered has shown no reports of fading or damage. While specific fabrics and dyes may be sensitive, these are rarely found in on-premises laundry applications.

Q: SOMEONE TOLD ME THEY TRIED OZONE LAUNDRY, AND YOU COULD SMELL THE OZONE FROM OUTSIDE THE LAUNDRY.

A significant ozone smell outside the laundry suggests either system malfunction or improper design. Proper functioning systems maintain ozone within acceptable limits.

Q: OZONE MADE MY LAUNDRY SMELL LIKE ORANGES!

This was common when citrus-based detergents were used. The orange scent can be eliminated by switching to non-citrus laundry detergents.

Q: IS THERE A MINIMUM SIZE FOR USING OZONE FOR COMMERCIAL LAUNDRY?

While we have clients with as few as 80 rooms, we typically target applications with at least 100 to 150 rooms to maximize return on investment. We strive to ensure payback within 18 months based on energy savings alone.

Q: IS OZONE DANGEROUS?

Similar to many laundry chemicals, ozone must be treated with care. High levels of ozone can lead to discomfort, including headaches and nausea, which may persist for up to 48 hours.
