8. Has pioneered aNew Processed – Non Corrosive Acidic Coil Cleaner and a New Processed – Non Corrosive Alkaline Coil CleanerBeing odourless, they can be used during normal business hoursHelping you avoid overtime costs

9. O3 Processed Acidic Coil Cleaner • Powerful. New-generation. New technology. • A non-corrosive chemical coil cleaner, specifically designed to remove contamination caused by: • General Dust or Dirt • Lint • Grime • Sea Salt

10. O3 Processed Alkaline Coil Cleaner Powerful. New-generation. New technology. A chemical coil cleaner, specifically designed to remove contamination caused by: • oil • grease • fat • aviation fuel

11. Current Cleaners? • Usually contain highly corrosiveHydrochloric acid • Will eventually corrode fins & coils • Do not leave a protective film, extending coils & fin life • Can cause acid burns on skin

12. Because it is Processed - O3 is Safe to use • Non-corrosive – will never harm coils or fins • Leaves a protective film • Odourless and eco-friendly • Completely safe to use during normal trading hours. • No overtime required • No acid burns to the skin

13. O3 Extends Equipment Life and Saves Money • O3 Acidic and Alkaline Coil Cleaners are concentrated • Mix the strength you wish to use on the job. • Dilute it 1:1, 1:5; 1:10, or as a wash 1:15 • Will never corrode the fins. • Protects coils and fins with a protective film

14. No matter how often you use O3 Coil Cleaners... this will never happen to your coils

15. It is essential that face masks are worn the first time O3 chemicals are applied • Standard old-fashioned, corrosive, hydrochloric acid-based cleaning chemicals clean to a depth of about 8cms. • Powerful, non-corrosive O3 cleaners penetrate beyond that, to the very core of the coil, removing dirt, bacteria, and other contaminants that have been building up ever since the coil went into service. As they are removed, they give off a pungent odour, which lasts for about 5 minutes. • Contaminants and bacteria that the tenants breathe in every day. • No wonder air conditioning has such a bad name

16. Case Study UTS had a problem at OR Tambo International airport. Kerosene contaminants from jet fuel are resistant to ordinary acidic coil cleaning chemicals Solution: O3 Alkaline Coil Cleaner - in a 1:1 dilution removed all dirt on contact

17. The panel was restored to mint condition Before After Airports round the world have the same problem. Coils facing the aircraft parking areas will always be coated with kerosene contaminants from the jet fuel. Ordinary acidic coil cleaning chemicals will not be effective against this problem. O3 Alkaline coil cleaner is designed to cope with these conditions quickly and efficiently.

18. Before and After Readings A MASSIVE 28.3% IMPROVEMENT IN AIR FLOW

19. Case Study The Gateway shopping mall – The largest mall in the Southern Hemisphere – Project Planned and executed by Senior Facility Manager, Ken Davidson

20. GATEWAY -Theatre of Shopping Umhlanga Using O3 Coil Cleaners, O3 Germ Free, and O3 Bio-Degreaser in one of South Africa’s biggest coil cleaning projects • 125 Coils cleaned, • 1600 “before and after” velocity readings taken, • showed an impressive 25% improvement in air velocity • Saving: R60,000 per day • Downtime reduced by more than 50%.

29. Mineralia Building in Braamfontein Johannesburg. The building is owned by Redefine and is more than 30 years old.

30. Please note the access to the back side (air leaving side) of the coils is near impossible to reach, but due to the penetrating capabilities of the 03 product we managed to clean the coils right through. Please note the access to the back side (air leaving side) of the coils is near impossible to reach, but due to the penetrating capabilities of the 03 product we managed to clean the coils right through. Francesco La Mantia of Ambassador Air in Johannesburg cleaned these coils. He reported as follows: “Please note the access to the back side (air leaving side) of the coils is near impossible to reach, but due to the penetrating capabilities of the 03 product we managed to clean the coils right through”.

31. As a result of the Mineralia coil clean we received the following letter Hello Michael, I met with Francesco and witnessed some of the equipment he had cleaned at one of our buildings. He will still send me the photos. The results were truly remarkable. I am by way of this E-Mail requesting all our service providers to utilise your product when they do the major services on our equipment! They already use another product which I suggest they now discontinue. I would certainly advocate the chemical be used in extreme situations! Regards Peter Brummer of REDEFINE

35. SANDTON CITY

36. After Before The coil serviced a restaurant and fast food area, so there was cooking oil and fat in abundance We used a 1:1 dilution of O3 Alkaline Coil Cleaner. The coil looked like new

37. EASTGATE

38. BEFORE AFTER A small coil, which hadn’t had its annual service. We used a 1:1 dilution of O3 Acidic Coil Cleaner. So much dirt came off, it blocked the drain pipe.

39. WATER DOESN’T CLEAN! IT MERELY RINSES If water cleaned, then we wouldn’t need soap in our shower or bath. Would we?

40. Rinsing down with water three times a year doesn’t clean the coil. It merely removes surface dirt and is a costly exercise • Costly because it wastes that precious commodity - water. • Costly because it hardly improves air flow, and therefore doesn’t reduce power consumption • It is far more cost-effective to use O3 coil cleaning chemicals in a 1:15 dilution. They will remove dirt and other contaminants, maintaining the levels of cleanliness achieved by the original O3 clean, and reduce energy consumption • They will also save a lot of water

41. O3 GREENAir Con Maintenance Programme You service your car regularly don’t you? You know that if you follow your service plan it will give years of trouble-free running. Then why not service your air con in the same way? It will assuredly extend its life and save you costly repairs. Just as you have an A Service, a B service, and a C service for your car, so you can have an A and B service for your air-con. Because O3 Acidic or Alkaline Coil Cleaner won’t harm or destroy the fins – no matter how often you use them, they are the perfect products for your service programme

42. O3 GREENAir Con Maintenance Programme Start with an O3 - A Service. Think of this as your major service to be carried out every year. As we have shown the O3 Acidic Coil Cleaner or O3 Alkaline Coil Cleaner in a 1:1 solution: • Is guaranteed to remove any contaminants in the system • Leaves an inhibitor to retard rust build-up. • Restores air velocity to optimum levels. • Completely safe for the eco system • Extends the life of coils and fins • Is part of the going green campaign

43. Now you can also use O3 Acidic Coil cleaner or Alkaline Coil Cleaner to do your general coil cleaning • B - SERVICE: Four months after that, do the O3 - B Service. It is a mid-term deep wash, which uses a dilution of 1:15 - O3 Processed Coil Cleaners. They cost less than R5.00 per litre – almost cheaper than water! • Continue to do the B service every four months for the rest of the 12 months cycle. • Then do the A Service to start the cycle again.
