The Green Coil Cleaner Coil Cleaning Demo At V & A Waterfront in Cape Town

GOING GREEN Programme The Designed to help you measure the effectiveness of your coil cleaning contract. Guaranteed to reduce energy and water consumption

of all energy costs in air conditioned buildings can be attributed to the air conditioning system 35% has been achieved in the very successful Gateway Programme, in Umhlanga reduction in maintenance cost by installing the latest chillers and using O3 chemicals! 25% 10% Energy Bill = R6, / per month, Saving = R600,000 / month Cost of Saving = R /month Achieved by using O3 chemicals!

The O3 GOING GREEN programme deals in facts.: How clean? How effective? How much? All measured, recorded, and evaluated. No thumb-sucking

Let us do for you what we are doing for The Gateway Shopping Mall The largest mall in South Africa Energy savings in AHU’s of R per month That’s R2,160,000 per year! At a cost to the contractor of R per year for his O3 chemicals. That’s what we call Going Green!

Because it is Processed - O3 is Safe to use Non-corrosive – will never harm coils or fins Safe on Aluminium and Copper Choice of Acidic or Alkaline coil Cleaners Leaves a protective film Extends the life of air con units Can be diluted 15 times and still be effective Odourless – use during normal office hours Part of the GOING GREEN campaign

Most property management companies in South Africa include a clause in their air con maintenance programme, in which they state that the AHUs are to be chemically cleaned once per year, and rinsed with water three times per year thereafter. But few companies have any way of monitoring that the programme is carried out as prescribed. More importantly, they have no way of measuring the effectiveness of the programme either. Water DOES NOT CLEAN - It merely rinses. If water cleaned, then we wouldn’t have invented soap.

The O3 GOING GREEN Programme is designed to: 1.Reduce energy consumption in AHUs, mid-walls, evaporators, condensors, cassettes, consols, South Africa and hideaways by keeping them in pristine condition for 12 months of the year 2.Provide Facilities Managers with accurate feedback on the results of the O3 coil cleaning programmes 3. Assist Air Con Maintenance Contractors to achieve those results efficiently, and cost-effectively 4.Through our distributors- Metraclark, provide a nationwide back- up service to the air con industry.

The Contractor must identify the contract building Where is the building situated? (town and street address) From this information O3 will link: GPS co-ordinates to direct the Contractor to the site the site-Technicians - we need their names the site’s Facilities Management the site’s Owner / Landlord TO START THE O3 GOING GREEN PROGRAMME

He will also identify all the site’s AHUs, mid-walls, cassettes, consols, evaporators, and condensors by serial number, or any other acceptable form of identification. those units servicing restaurants, fast food outlets, bakeries, or any form of cooking. They will require O3 Alkaline Coil Cleaner instead of the normal O3 Acidic Coil Cleaner.

The O3 Website GOING GREEN Programme 1.The Contractor sends the information to O3 Control either by linking to our website, or ing a spreadsheet with all the data recorded 2.From this info O3 Control will print up a colour-coded gummed identity tag for every unit, which will be sent to the Technician 3.He will attach them on a conspicuous spot on the upper frame of each specified unit 4.The colours of the tags match the colours of O3 bottles 5.The coloured tags serve to remind the Technician which product to use on the coil when cleaning it

The O3 Website GOING GREEN Programme ABC Green identifies that the coil should be cleaned with O3 Acidic Coil Cleaner

The O3 Website GOING GREEN Programme DEF Yellow identifies that the coil should be cleaned with O3 Alkaline Coil Cleaner

The O3 Website GOING GREEN Programme GHI White label identifies that the coil should be cleaned with O3 SmartAir and SmartFinish

1.After the colour-coded tags have been attached, 2. The Technician measures the Length x Height of every unit on site 3.The information, which is linked to the tag, is sent via his smart phone to O3 Control. 4.Alternatively he can enter the information on an O3 Excel spreadsheet, and it to O3 Control Gathering the Information

1.O3 Control will capture the information, and establish a dataset. 2.Every time the Technician services the unit, he will use his smart phone to scan the tag, and send the “Before” and “After” results to O3 Control 3.Alternatively he can send them on a spreadsheet. Establishing a Dataset

All data relating to this identification links to: where the units are situated on site – by floor, and location AHU measurements (length and height), including measurements for all the other units (mid-walls, consols etc) in the air con system From these, the O3 Program calculates the volume of the AHU in m². to determine the quantity of O3 chemicals needed for cleaning. Establishing a Budget

O3 uses 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. O3 SmartAir O3 SmartFinish

The O3 GOING GREEN 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 doesn’t clean. Chemicals clean Water is only used to rinse off the chemical.

The O3 programme keeps the coils and fins in pristine condition for 12 months of the year It leaves a protective film, which extends the life of units O3 can prove it saves energy it also saves vast quantities of water. The O3 programme records every detail of the various cleans How Clean? -The Benefits

Using the camera on his smart phone, the technician points it at the tag. He will be linked 1. to the O3 Web-site Asset Management Programme: 2. it will Identify the building where the coil is situated 3. It will Identify the coil in the Programme 4. He records the appearance of the coil by taking a picture. How Clean? The Clean

1.He records the “Before” air flow readings with his anemometer. 2. Using his smart phone, he transmits them to O3 control Alternatively he can record the readings on a spreadsheet.

The air flow readings are taken in the following manner: Start at the corner top left. Obviously there would be fewer readings on smaller coils

He then applies the O3 chemical

Uses his smart phone camera to capture the amount of dirt coming off the coil.

After the rinse-down, the technician takes pics of the coil Before After

24 hours later, the technician records the “After” airflow readings, and sends them to O3 control Obviously there would be fewer readings on smaller coils How Effective?

1.The programme records all the data onto a spreadsheet. 2.The data is also transposed onto a coil image. 3.This enables the contractor (wherever he may be) to “see” the results of the clean on the coil. The top figure is the “Before” reading and the lower is the “After” reading In this case, where there has been no improvement, we would ask the technician to re-clean that area.

1.Have a look at the next slide. We use colour-coding to differentiate among the results achieved 2. Red is for improvements in air flow of more than 50%, This shows that the coil was very dirty 3. Yellow is for improvements between 20%-40% 4. Green is for less than 20%. It indicates that the coil was in a reasonably good, clean condition at the start of the clean, and therefore the percentage improvement was low. 5.The target improvement is less than 10%. It shows the coil is in pristine condition

1.We realise of course that the Facilities Manager and the Contractor do not have time to trawl through hundreds of readings. 2.They don’t have to! That’s our job. 3.O3 Control analyses all the data, and prepares a report, which is submitted to the Facilities Manager and the Contractor

How Much? It is essential that a Contractor should know in advance what the cost of chemicals will be for a contract. O3’s programme does this, including detailing the cost of the different types of chemicals needed for the job. O3 creates an estimate of chemicals required by chemical type (either Acidic or Alkaline coil cleaner) for each AHU, or O3 SmartAir and O3 SmartFinish for mid-walls, consols, cassettes, and hide-aways

From this O3 creates a total budget by chemical for the entire building O3 also creates a budget by chemical (Acidic Coil Cleaner or Alkaline Coil Cleaner) for each clean i.e. a 1:1 dilution once a year, and a 1:15 dilution three times per year. the budget automatically works out the number of bottles (concentrate) required to clean by type.

Metraclark, SA’s largest air con and refrigeration wholesaler, mentors the O3 programme The O3 chemicals estimate is submitted to Metraclark, who will price the chemicals by product. The programme automatically creates a total budget for chemicals for the site. A first in the industry. The programme is designed to help the Contractor limit his chemical purchases to the requirements of the contract. No excessive stock- holding.

Every time the Contractor orders chemicals for a particular contract, he, or his technician, will be required to submit a purchase order to Metraclark stipulating against which contract they are ordering. In this way Metraclark and O3 keep a record, which will allow the Contractor to see what quantity of chemicals are being used on site against the established budget. It’s a check, which we think is essential. Helping the Contractor with his stock-holding

10 days before any clean is due to take place: O3 will alert the contractor. From the budgets O3 has prepared for him, he is advised what quantities of each of the chemicals will be required to do that particular clean. Metraclark will follow up to ensure the stock is on hand It means tighter stock controls – and less stock-holding for the Contractor O3 Helps the Contractor to plan ahead O3 leaves nothing to chance.
