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 GREEN 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
Case orders may be mixed, for example: 1 case O3 SmartAir +1 case O3 SmartFinish to make up a 2 case order. Or 1 case O3 SmartAir + 1 case O3 SmartFinish + 1 case O3 GREEN + 1 case O3 Alkaline D + 1 Case O3 Bio Degreaser for a 5 case order. Mix them as you please.
AHU’s: 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, and sanitised 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 or sanitise, 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.
