South Africa’s No 1 in Refrigeration

Case Study

UTS had a problem at OR Tambo International airport.

Kerosene contaminants from jet fuel are resistant to ordinary acidic coil cleaning chemicalsSolution: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.

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

• 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%.

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

WATER DOESN’T CLEAN!

IT MERELY RINSES

If water cleaned, then we wouldn’t need soap in our

shower or bath. Would we?

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 breath in every day.

• No wonder air conditioning has such a bad name

• 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 power consumption

• They 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 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.
