You can make your preventative maintenance easy
Care-Free Conditioners overcome hard water problems
When installed in a cooling tower system Care-Free virtually eliminates the biofilm in which bacteria grows and multiplies. Therefore, minimal regular maintenance is required to keep the tower in a ‘clean’ condition.

Care-Free Keeps Your Condenser Tubes 'Shining Like A Gun Barrel'
These condenser tubes are shining like a gun barrel after 15 months of Care-Free water treatment. To give an indication of tube cleanliness, a torch light is easily seen through the four metres of condenser tubing. No chemical treatment was used and no scale or pitting was evident. All that was required was a soft brush clean which was more of a formality than a necessity.
The following summary findings were taken from a report by the Benalla Regional Office of the Victorian Health Department after a two year study of the Care-Free Water Conditioner.

| Introduction | What are the results of the experiment thus far? |

This paper represents an alternative non-chemical means of managing the aquatic environment of cooling towers, in a way that appears to preclude the proliferation of bacteriological contaminants.
A water conditioner was sized to the cooling tower circulation rate and reservoir capacity, and installed as a by-pass circuit that would circulate the cooling tower water through the conditioner for 12 hours every day. Prior to commencement of the experiment, a number of parameters were decided which are as follows: (a) an adjacent cooling tower which did not have a water conditioner fitted, would be subject to the same schedule of tests as the cooling tower which did have the water conditioner device fitted. (b) both cooling towers would be thoroughly cleaned. (c) one cooling tower would continue to use biocide and algaecide chemicals and the cooling tower which had the water conditioner device fitted would not use any chemicals. (d) a program of tests and inspections was scheduled. (e) TBC dip slide tests were taken and recorded. The test schedules were: Total Bacteria Count, Legionella Count, Total Dissolved Solids, Alkalinity, and pH. What was of major significance, and is possibly the most important point of this paper, is that during the two year experiment, no algaecide or biocide chemicals were used in the cooling tower with the water conditioner device fitted. Throughout this time, the test results as provided by a NATA certified testing agency have identified the lowest detectable levels of all legionellas which is <10 CFU/ml, and the TBC has consistently remained at less than 10³. This is an excellent result for cooling towers which are using chemicals, but is an exceptional result from cooling towers which are using no biocide or algaecide chemicals. |
(a) The device appears to be able to consistently maintain a TBC of below 1 x 10³ CFU/ml and a Legionella bacteria count of <10 CFU/ml.
(b) The cooling tower is visually clean. (c) The condenser tubes on the water side of the refrigeration unit condenser allied to this cooling tower, were not cleaned at the commencement of the experiment. However when the condenser end covers were removed for their seasonal inspections and tube cleaning, every tube was observed to be completely clean and shining like a gun barrel. What benefits has the project identified thus far? (a) The cooling tower is dispersing neither Legionella or biocide aerosols. (b) The cooling tower no longer requires cleaning except for the requirement to desludge the water pan. (c) The shell and tube condensers attached to the refrigeration machinery no longer require cleaning or brushing. (d) An additional benefit of item (b) is that the compressor efficiency is not impaired or reduced because of dirty or scaled condenser tubes. (e) The use of cooling tower chemicals has been eliminated subject to the Total Bacterial and Legionella counts remaining below a specified limit. The two year field test experiment had thus far substantiated that the aquatic environment of a cooling tower and an evaporative cooler can be controlled using what has traditionally been known as a proprietary device. The evidence supporting this is the visual results of the experiment and the certified NATA laboratory test results of the water samples. |
Consider these boiler results from Tijuana, Mexico...
Hospital General Regional No 1
Hospital Engineers were at a loss of how to reduce scale in their three boilers…
That is, until a 25mm Care-Free was fitted to each boilers re-circulation line
Smaller Care-Free units were also fitted to the cold water supply lines.
A few months after installing the Care-Free Conditioners, this bucket of hard scale was removed from just one boiler
According to the Hospital Engineer ‘magnetic’ water treatment systems were also tested and proved unsuccessful in removing calcification.
Here’s another example of the Care-Free Advantage…
This time the difference is in the Cooling Towers of the Canberra Deep Space Communication Complex
Two 125-150MkII Care-Free Water Conditioners were installed in the re-circulation line of the cooling towers. Plus a smaller Care-Free unit was fitted before the water softening plant.
Since installation, there has been considerable reduction in the water usage as the cooling towers no longer dump as much water. What’s more, no bags of salt have been added to the water softening plant and there is no evidence of hard scale in the entire plumbing system.
Care-Free Units installed directly after the pump.
Scale simply wipes away...
At the Casa Maya Hotel, Mexico, a Care-Free Conditioner was fitted to the main water supply.
This demonstration shows how easy calcification is removed from a saucepan, after the Care-Free treated water was boiled dry. Because Care-Free changes the form of Calcium Carbonate (CACo3) from Calcite (hard) to Aragonite (soft).
Watch below how easily it wipes away…
