Water Fed Pole Technology explained
This technology is known by many as either reach and wash or water fed pole systems.
When water is used for window and façade cleaning, impurities from the surface are suspended in the water as it strives to return to its pure state. The surface is then finally rinsed from top to bottom forcing these impurities to flow down the surface by means of gravity. This process leaves the surface being cleaned sterile and free from any mineral deposit.
The purification process is achieved in two parts, firstly by reverse osmosis and finally by de-ionization.
This is a series of filtration stages that begin to strip impurities from the water as it passes each stage of the system.
Water from the mains supply will have been processed to a certain level fit for drinking and also have fluoride and other health benefiting properties added to it.
Generally tap water that is tested with a standard TDS meter, would have between 35 parts per million (035ppm) and 400 parts per million (400ppm) depending on where in the country you are.
These figures represent the hardness or mineral impurities in the water.
The process of filtration detailed above will leave the water testing at 000 parts per million (000ppm.)
This water is then fed via pumps, through hoses to a brush attached to the end of a pole. The brush is used to scrub all the dirt and debris from the window unit whilst a constant flow of water is helping to flush the dirt from the unit.
