Water ozonation in laundries is an advanced technology that significantly reduces detergent, hot water and energy use, and extends linen life and shortens wash time. Ozone dissolves in water and replaces part of the chemicals, ensuring superior cleaning quality.
This is a fundamental change in washing: you replace harsh chemistry with something that works much better. So much better that water and time use can also be reduced while achieving superior results.

Comparison of traditional and ozone washing
| Parameter | Ozone washing | Traditional |
|---|---|---|
| Water temperature | Cold (15-25°C) | Hot (60-90°C) |
| Electricity consumption | 70-100% less | Baseline |
| Detergent consumption | 30-50% less | Baseline |
| Water consumption | 20-40% less | Baseline |
| Linen wear | Minimal | Increased |
| Disinfection | 99.9% | 95-98% |
Why cold water is more effective
Washing quality depends on 4 factors: water temperature, chemicals, wash time and mechanical action. Using ozone, you can replace chemistry and temperature with a more effective solution.
- Ozone creates hydroxyl radicals (OH) at pH 8 in cold water — the same as at high pH with hot water
- The colder the water, the more stable ozone is and the longer it works
- Above 95°C ozone loses effectiveness due to faster decay
- Cold water does not damage fabric fibers — linen lasts longer
- Absence of chlorine bleach with hot water prevents chemical reactions that damage fabric
Technological process
| Traditional laundry | Ozone laundry |
|---|---|
| Hot water | Cold water |
| Alkali | Ozone |
| Detergent | Detergent (less) |
| Acid (neutralization) | — |
| Bleach | — |
Ozone spontaneously decomposes to oxygen and does not require removal unlike traditional chemicals. This allows reducing the number of rinses by 20-40%.
Benefits of ozonation in laundries
Energy savings
70-100% reduction in water heating costs. Complete washing in cold water.
Improved disinfection
Ozone effectively destroys viruses and bacteria even at low temperatures.
Softer linen
No chemicals remain in fibers. Linen becomes softer.
Better whitening
Strong oxidizing properties of ozone ensure brightness without chlorine.
Ozone cabinets for dry cleaners
Dry cleaners use ozone cabinets — sealed chambers filled with high-concentration ozone. As a gas, ozone penetrates the densest fabrics and hard-to-reach areas.
Treatment of delicate items
Theatrical costumes, vintage, fur coats, leather jackets, motorcycle helmets, hockey gear. No mechanical action or heating — minimal risk of damage.
Odor removal (deodorization)
Fire smoke, ingrained tobacco smoke, biological odors, animal odors, mustiness. Ozone destroys the cause of odor at the molecular level.
Disinfection
Destroys cell membranes of bacteria, virus envelopes and fungal spores. Ideal for children's items and bedding.
Monetization
Service is sold as an additional option (upsell) or as a separate VIP service. Cycle cost is minimal.
Equipment selection
| Laundry type | Recommended equipment | Cost |
|---|---|---|
| Small laundry | Ozone generator 5 g/h | from 250,000 ₽ |
| Hotel laundry | Ozone generator 10 g/h | from 320,000 ₽ |
| Commercial laundry | Ozone generator 20 g/h | from 420,000 ₽ |
| Dry cleaner (700L cabinet) | Ozone cabinet OZ-1S | from 420,000 ₽ |
| Dry cleaner (1400L cabinet) | Ozone cabinet OZ-2S | from 500,000 ₽ |
Technology limitations
In some cases, a small amount of hot water will still need to be used. Cold water is not suitable for working with greasy stains (lipstick, shoe polish, ink) due to the physical nature of fat at low temperatures.
- Heavily soiled linen with greasy stains requires a separate program with hot fill
- Such loads usually make up a very small percentage of total volume
- For the remaining 90%+ of linen, ozone washing in cold water is the optimal solution
ROI and payback
- 50-70% reduction in electricity bills (water heating is the main expense)
- 30-50% savings on detergents and bleaches
- 30%+ extension of linen life (fewer replacements)
- Reduced wash time — more cycles per day
- Typical payback period: 12-18 months
