| IN PRACTICE | GLASS AND BUILDING FRONTS Water lances point the way Face value New regulations, technological innovations and customer requirements are shaping the way building fronts are being cleaned today. the company is run by professionals who are serious about what they do and how they do it. That is why effective and regular cleaning is an absolute must. When cleaning building facades, a number of issues need to be addressed, however. Chief among them: accident prevention. In this regard there have been quite a few regulatory changes. Although new legislation will always have an impact on the direction in which an industry will evolve, technological progress still plays a major role. This is most apparent in the most familiar type of facade care: window cleaning. Thanks to the advanced engineering that goes into tools that make cleaning windows quicker, safer and more efficient, the days of conventional window cleaning with a ladder, chamois cloth and a bucket are numbered. Water lances have become the preferred equipment of professional window cleaners because they make it easy to clean tall buildings and high-up windows with both feet safely on the ground. It is no longer necessary to spend so much time aloft in a precarious situation. Water lances work with distilled water because it leaves no stains or streaks on glass and other surfaces, and it makes the use of chemicals unnecessary. Purified water, as the name says, is water in its purest form. To reach that quality, it first has to be processed, however. This means removing all salts, minerals and impurities that would otherwise dry and cause stains and streaks on the surface. Also known as Total Dissolved Solids or TDS, these impurities are measured in parts per million or ppm. Water is considered pure when the TDS value is 0 ppm. There are two established methods Next-generation water lances: a better balance between weight and for purifying water in the industry: stiffness. Photo: Unger Deionization (DI) – water is filtered through an ion exchanger (resin) that captures and removes 99 percent or more of the salts and impurities present in the water; It’s the first impression that counts. This simple truth applies Reverse osmosis (RO) – water is pressed through several to all aspects of life – and that includes the public image of a membranes which successively retain and capture the salts company or brand. It also explains why companies, businesses and impurities. and institutions attach great importance to clean and crisp-looking Water lances are continuously being improved, with advances in headquarters. Not just on the inside, but also, and perhaps design and engineering, but also in terms of the materials used. especially, on the outside. A building exterior is like a billboard. If These systems are also becoming more user-fiendly, and achieving it doesn’t make a good impression, it might turn off current and better cleaning results with less time and effort. Ultimately, prospective customers, and lead them to take their business this makes them much more cost-effective as well. Next-generation elsewhere. A clean, cared-for building front – whether it’s an office, water lances impress with their ability to combine light weight factory, retail outlet or warehouse – shows the whole world that with outstanding stiffness.
