Has pioneered a New Processed – Non Corrosive Acidic Coil Cleaner and a New Processed – Non Corrosive Alkaline Coil Cleaner Being odourless, they can be used during normal business hours Helping you avoid overtime costs

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

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

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

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

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

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

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

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

The panel was restored to mint condition 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. BeforeAfter

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

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. 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.

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 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

SANDTON CITY

Before After 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

EASTGATE

BEFORE AFTER A small coil, which hadnt 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.

WATER DOESNT CLEAN! IT MERELY RINSES If water cleaned, then we wouldnt need soap in our shower or bath. Would we?

Rinsing down with water three times a year doesnt 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 doesnt 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

O3 GREEN Air Con Maintenance Programme You service your car regularly dont 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 wont harm or destroy the fins – no matter how often you use them, they are the perfect products for your service 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 O3 GREEN Air Con Maintenance Programme

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.
