Ozone Laundry System for commercial application. Use of Ozone reduces heating & chemical cost. ozone is very powerful disinfectant & oxidant compare to conventional Chemicals. Ozone is safe on linen & environment. Use of ozone reduces water & waste water quantity. Ozone laundry is very effective on hospital infected clothes. Ideal for oily & heavily soiled clothes.

1. Eco-sustainable solutions
For
Commercial LAUNDRY

2. Ozone has been successfully applied in
commercial laundry for more then 50 years.
Ozone In Commercial Laundry
Integration of ozone in laundry systems are growing due to:
 High Quality washing.
 Reduction in chemical use.
 No requirement of Steam.
 Operational ease.
 Performance & efficiency.
 Cost benefit.
 Environment friendly.

3. Advantages of Ozone
In
Commercial Laundry

4. Odour removal
 Ozone is a strong oxidizer.
 It eliminates all bacteria & organics causing odour.
 Eliminates use of bleach, hence no chlorine odour.

5. stain removal
 Ozone is a strong but natural bleaching agent, hence good for whites
& coloured clothes.
 Breaks bonds that holds soil & stains to the linen.
 Breaks down organic stains like oil & blood stains.

6. Ozone protects cloths
 System uses cold water, avoiding fabric shrinkage, aging &
deteriorations caused by using hot water/steam.
 Reduced quantity of detergent used.
 Eliminated the use of bleach, which makes clothes hard & brittle.

7. Ozone disinfection
 Ozone is a strong disinfectant
– about 3 times stronger than chlorine.
 It kills all viruses & bacteria.
 Prevents cross contamination.

8. Softer linen
 Ozone penetrates inside linens making it fluffier.
 Ozone prevents building up of residue in the weaver of the cloth
leaving fibres naturally soft & resilient.

11. Cost of heating water for 110 kg washer
 Drum capacity 800 litres
 Inlet water temperature 50˚C (Steam Condensation)
 Washing temperature 95˚C. – Temperature rise
required 45˚C
 36,000 kcal required to heat water
 Linen capacity – 110 kgs.
 3,300 kcal required to heat linen
 Total 39,300 kcal required per wash cycle
 Boiler efficiency is assumed 80 %

12. Cost of heating water cont. …..
 Boiler efficiency is assumed 80%
 For 39,300 kcal, boiler produces 49,125 kcal
 Heat transfer losses @ 15% (from steam to washer)
 Total heat required from boiler is 57,800 kcal.
 1 litre of boiler oil can produce 9,000 kcal
 Total 6.5 litres of boiler oil is used per wash cycle
 With 12 wash cycles per day & 300 days per year
 Total oil consumed per washer is 23,400 litres
 Considering rate of INR 24/- per litre for boiler oil
 Yearly expense is INR 5,61,000/- (heating cost)

13. Chemical costs
 Bleach (Sodium hypo chloride).
 0.75 litre per wash cycle.
 Cost of bleach INR 12/- per litre.
 Yearly cost INR 32,400/- (Chemical cost)

14. Ozone costs
 Running cost – power consumption – 0.6 kw per hr.
 Operating Hours – 20 hrs.
 Considering INR 10/- per kwhr.
 0.6 x 20 x 10/- x 365 = 43,800/-
 Yearly cost is INR 62,400/- (including Tax & maintenance cost)

15. Net saving using Ozone
 Operational Cost saving :
Heating cost + Chemical cost – Ozone operational cost
⇛ 5,61,600/- + 32,400/- ̶ 62,400/- =
 Other savings & benefits :
 Increased life of cloths
 Saving in water & detergents
 Cleaner effluent – no chlorine or its harmful by-products
 Safer on environment – No burning of boiler oil
INR 5,31,000/-

16. Commercial Viability / Pay back
 Capital Cost :
 Per system ranges from INR 2.0 lac to 4.0 lac
(estimated ozonator life is 10 years)
 Pay back period :
 Cost of net consumables in conventional laundry is
INR 5.31 lac.
Capex pay back is 6 months to 8 months
