Why use colour change resin? This was the original question posed by Sean.
For the first three years the Reach & Wash system used regular MB400 in regular column cyclinders, each system was sold with a TDS meter. Generally we never hear from a customer unless they have a problem, usually the kind of problems we heard of in those days was when a customer would ring up and complain that their system was leaving spots on their customers windows. Our first question was; what is your TDS reading? Common answers where, d'know, lost the TDS meter, d'know the TDS meter is not working, d'know what is TDS?
Despite the training and despite issuing an instruction manual, window cleaners in general just want to get on with their work and pay little attention to maintenance of their machine. So we'd send them a new TDS meter in order to establish if the problem was down to water quality or some other factor. Meter reading comes back high, so we send out new filters and bag of MB400. All very well, but what has happened?
The customer was unable to use the machine with confidence while all this got sorted out, and once it was had to go back over some of his work in order to satisfy his customers who had complained. This situation does little for the reputation of the window cleaner nor the reputation of our Reach & Wash systems.
The solution was to make it a no brainer so we use colour change resin in a clear filter cartridge of our own design and manufacture (Doesn't a company that manufactures its own filters that have been independently tested by the Water Research Council qualify as a water treatment company?). Now customers can see at a glance if their water quality is OK. This leads to a higher quality window cleaning service from Reach & Wash users than from users of other systems. In turn we get less complaints about water quality which means that our customers get less complaints about the quality of their window cleaning service. These days, on the rare occassion that a customer does ring our first question is; what colour is the colour change filter? if its not blue then the problem is very quick to resolve and the customer has less down time, he also knows how to look out for the same problem in the future.
In window cleaning time is money not the cost of one type of resin over another. TDS meters go out of calibration, get lost, broken, stolen, dropped into buckets of water. Colour change is quick, simple, delivers and causes less down time, and because of this works out to be much, much cheaper. If the old way was any good, then we'd still be doing it would'nt we?
Dom, we're IONIC SYSTEMS LTD not OTT any more!
