The O3 programme deals in facts. How clean? How effective? How much? All measured, recorded, and evaluated. No thumb-sucking!
How Clean? O3 advocates 1 deep clean every year using a chemical dilution of 1:1, and three cleans using a chemical dilution of 1:15. Water is only used to rinse off the chemical. Water doesn’t clean. Not only does this system keep the coils and fins in pristine condition, but it saves vast quantities of water. The O3 programme records every detail about the various cleans.
Below is an illustration of what happens when a 1:1 dilution of an O3 coil cleaning chemical is used on a coil which has been cleaned for years using an ordinary coil cleaning chemical, and three rinses a year with water.
How effective? We are not interested in being told a coil is clean. We want to know how clean? The best way to assess the results of a coil clean, is to measure the improvement in air flow. Therefore it is imperative that we teach technicians how to use an anemometer. We insist on doing readings before and after each clean. We do comparative checks after each clean to see whether the programme is maintaining the required levels.
The O3 Programme will transpose the "before" and "after" figures onto an image of a coil so that the technician, and the contractor can see where there may be a problem which may need attention
Nothing is left to chance in the drive to reduce energy and water consumption.
How Much? We believe it is essential that a contractor should know in advance what the cost of chemicals will be for a contract before any work is started. O3’s new programme will do this. It even details the cost of the different types of chemicals needed for the job.
But more than this. It will also:
Start by identifying the building in which the work is being done:
We ask the contractor to give us the following information:
The next step is to list the AHUs, mid-walls, cassettes, consols, under-ceiling units, and condensors in the building. It is preferable to identify where they are situated in the building – on what floor, and where on that floor the unit is situated. This will make it easier for all when "before" and "after" air flow readings are done. If there is a problem we can isolate the unit, and determine what outside elements are influencing it.
We need the AHU measurements (length and height), as well as the measurements for all the other units. From these we can work out the volume of the AHU in m². This helps us to determine the quantity of O3 chemical needed to clean the unit.
We need to know whether the AHUs are servicing a general area in the building, or whether they are servicing restaurants, fast food outlets, or any cooking areas. This will determine which of the two O3 chemicals we will use to clean the AHUs.
We use specially developed chemicals to clean mid-walls, cassettes, consols, under-ceiling units, and condensors. O3 SmartAir and O3 SmartFinish will do the job quickly, efficiently, and cost-effectively - and they don’t need water.
