We have invested in the lastest light weight poles allowing us to reach those high level windows
When water fed pole window cleaning was 1st introduced there were a limited amount suppliers of equipment, most of the equipment available was heavy and fatiqued the operator quickly on the higher level cleaning, This reduced the end results
New technology has allowed us to invest in water fed poles that are less than half the weight of the original poles giving superior cleaning results
The poles that were 1st availble were not just heavy but were a long length when closed, up to 12ft, this made putting the pole up very tricky, This was carried out by extending the pole on the ground and then pushing the pole up like a scaffold pole meaning 2 people were needed to operate this pole and lowering the pole is also tricky as this had to be carried out but lowering it down the building which means you needed a fair amount of room to lower it, not ideal in a busy high street, The new generation poles are higher when extended with only 6ft sections so can be put up by one operator and stored in smaller vans
Mixed Bed Resin
ReplyDeleteWhen the pure water coming out of your DI bottle isn't as pure as it was or should be and it's time to replace the mixed bed resin, don't throw away the resin that's in the bottle.
If your water was originally going into the DI bottle at say 84 ppm (parts per million) and was coming out at 0 - 2 ppm but is now coming out at over 11 ppm then it's unlikely that your pure water cleaning system is leaving the windows you've cleaned, spot free.
By obtaining and using a new DI bottle and new mixed bed resin, you can continue to use your first DI bottle with the used resin still in it, as a pre-filter for your second DI bottle.
This means that with two DI bottles instead of one, the water that is still coming out of the first DI bottle with a reading of 11 ppm, is what is going into your second DI bottle with the new and unused mixed bed resin.
This second bottle is now only having to clean incoming water with impurities of 11 ppm instead of with the original 84 ppm.
This will result in your mixed bed resin in the second bottle lasting a whole lot longer than your original bottle lasted.
The savings in having to replace your mixed bed resin less often, will more than cover the cost of buying your second DI bottle.
When the water you're using starts to come out of the second DI bottle at around 11 ppm again, simply use that as your first bottle and replace the well spent mixed bed resin in your original bottle with new resin and use this DI bottle as your second filter.
This system will ensure that the bottle that your pure water is coming out of, always has water going into it at only around 11 ppm instead of 84 ppm.
