O3 Alkaline D: A powerful, new generation, new technology, non-corrosive,
concentrated chemical cleaner, with a built-in degreaser, specifically
designed to remove health-threatening mould, bacteria, and fungi growing
in grease, cooking oil, and fat in air con systems servicing restaurants,
bakeries, fast food outlets, and kitchens generally.
Can be diluted up to 15 times, making it the most competitively-priced Alkaline D on the market .
A New Way to Apply The Chemicals
O3 has also developed a new way of applying our chemicals. We reasoned if we could get enough pressure to penetrate right through a coil without damaging it, we could more easily remove contaminants bearing mould, bacteria and fungi. We tested many compressors, but always found immediately we started spraying the chemical onto an AHU, or HVAC, the pressure would drop alarmingly.
We finally had a breakthrough when we discovered the latest ”Trade Air” oil-free, silent compressors, which, unlike ordinary compressors, maintain their set pressure throughout the length of the clean.
They have also enabled us to introduce new cleaning techniques, which are extremely cost-effective, and far more efficient compared to the normal method of applying the chemicals with a garden pressure pump, and a hosepipe to rinse off. Instead they reduce cleaning times dramatically, and enable the technicians to limit the amount of water required to rinse off a chemical to just a few litres.
To do a first-time clean, we use a 50 litre Trade Air Twin Head silent compressor, set at 5-bar pressure. We apply O3 Alkaline D in a 1:1 dilution. The chemical is poured into a 1-litre paraffin spray gun attached to the compressor. The constant pressure from the compressor will allow us to clean right through the coil, without having to clean from the reverse side as well. Because of this consistency, we use a far smaller quantity of chemical. Leave the chemical on for 15 minutes.
Extremely important. DO NOT USE A HOSEPIPE TO RINSE OFF. A 20mm hosepipe spews out 80 litres of water per minute! Rather pour the water into the paraffin spray gun, and rinse of at 5-bar pressure. It is amazing how little water is required – just a few litres! Cleaning times are reduced dramatically. No mess to clean up afterwards!
AHUs: We have always recommended AHUs should be cleaned 4 times
per annum. The first clean should be done using O3 GREEN or O3 Alkaline
D in a 1:1 dilution. Before and after air flow readings are essential to
monitor the effectiveness of the clean. Thereafter a clean should be done
every three months using a 1:15 dilution of either chemical. Again air
flow readings must be taken. We also strongly advocate the taking of before
and after pictures, using a smartphone or tablet.
FILTERS: Filters play an important role in reducing mould development in an AHU or HVAC. They should always be kept in pristine condition.
AHU Filters: We believe filters servicing food outlets in a shopping mall should be cleaned at least every 8 weeks. Filters in AHUs servicing line shops should be changed every 12 weeks. Do not wash with water. Water doesn’t clean, and the residue moisture on the filter after the clean with water, attracts mould, bacteria, and fungi. Rather use O3 SmartAir and O3 SmartFinish to do the clean.

O3 Alkaline D (with added degreaser) is the most powerful Alkaline cleaner on the market today. Formulated to quickly and efficiently remove oil, grease, cooking oil, and jet fuel from air con and refrigeration units. Leaves a fresh after-clean fragrance. It’s non-corrosive and has a protective film to extend the life of the units on which it is used.
Caution: Health and safety regulations require that gloves, goggles, and a mask should ALWAYS be worn.
The Trade Air compressors can be bought at Makro, Takealot, and many other
similar retailers. However, we place so much importance on this method
of cleaning AHUs and HVACs that O3 has decided to offer the compressors
as part of our programme. We believe our prices are lower than the competition.
We are keen for the Contractors to recover the cost of the machines in
a matter of months, while delivering a far higher standard of cleaning
for their clients.
The Trade Air compressors will guarantee Property Owners, and Facilities Managers will achieve more cost-effective, and more efficient results from their contracts.
