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

Clean? How Clean? It is almost impossible to know whether a coil is completely clean after using chemicals unless the “before” and “after” air flow readings are taken using an anemometer Doing a coil clean without an anemometer is like passing your matric without knowing the results!

The following case studies show how important we believe “Before” and “After” readings are in determining the actual health of an AHU. Not only will they show by how much the airflow has improved, but also where the weaknesses and strengths are in the system

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 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.

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

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”.  

He will still send me the photos. The results were truly remarkable. 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

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 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.

Bluchem recommends O3 chemicals to clean their coatings. Comprehensive tests have shown that O3 will not corrode, attack, or remove the coating in anyway at all Be aware though there are coatings on offer on the market under a similar name, which do not match Bluchem’s standards. O3 cannot, and will not be responsible if these coatings are removed with the rest of the contaminants when O3 chemicals are applied. Pre-clean tests are essential

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

Rinsing down with water three times a year doesn’t clean the coil 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 flow, and therefore doesn’t reduce energy consumption It is far more cost-effective to use O3 in a 1:15 dilution. It will remove dirt and other contaminants, maintaining the levels of cleanliness achieved by the original O3 clean, and reduce energy consumption O3 will also save a lot of water

O3 GREEN Air 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 coils and fins – no matter how often you use them, they are the perfect products for your service programme

O3 GREEN Air 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

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 R 30.00 per 5 litres – 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.
