O3 Chemicals - Cutting Your Water Bill

Because we as an industry must save water, O3 has developed a new way of applying 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.

AHUs, Chillers, large Condensors

The compressors have enabled us to introduce new cleaning techniques, which are extremely cost-effective, and far more efficient compared to the normal method of applying 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 GREEN in a 1:1 dilution. The chemical is poured into a 1-litre pot in a 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 1-litre pot on the paraffin spray gun, and rinse off at 5-bar pressure. It is amazing how little water is required – it can be measured in just a few litres HVAC’s

O3 uses a specially developed waterless method to clean mould, bacteria, and fungi- contaminated dirt from HVAC’s.

We apply the new O3 SmartAir to deep clean, and O3 SmartFinish to rinse off, without removing the units from the walls. The compressor is set to 1-bar. (The only time a unit is removed is to clean the barrel fan). Even then, it is not necessary to remove the fan to clean it. Think about it – no broken clips, and no broken fans). The HVACs will be left in pristine condition in less than 20 minutes. It requires only miniscule quantities of chemicals to do the job. And no water at all!

It leaves a protective film, which extends the life of units
