High-Level Window Cleaning with Pure Water

Unger systems for window cleaning with pure water Pure water window cleaning allows you to work on windows, façades and other exterior surfaces using a system consisting of filtration equipment, a water-fed pole, a brush and hoses and connectors. The system reduces the minerals present in the incoming water. When the water reaches the required quality and the surface is cleaned and rinsed correctly, it can be left to dry without using a window squeegee. This pure water window cleaning system allows you to work from the ground using Unger nLITE poles and can reduce the need for ladders, scaffolding or powered access platforms on many jobs. The achievable height depends on the pole material, length and configuration. More rigid nLITE configurations are designed for high-level work, with Ultra HiMod systems reaching approximately 20 metres working height. What do you need to clean with pure water? A pure water cleaning system normally consists of four main elements: filtration equipment, a pole, a brush, and a hose and connection system. 1. Pure water production system Filtration equipment reduces the minerals and other substances present in the incoming water. The appropriate technology depends mainly on water quality, frequency of use and the amount of pure water required.DI deionisation: uses ion exchange resin to reduce dissolved minerals. It is a straightforward solution for certain usage levels and water conditions. HydroPower NANO: combines a pre-filter, nanomembrane and DI deionisation in a hybrid system that can operate without a pump or electrical connection. RO reverse osmosis: uses membranes and different filtration stages to produce pure water and is particularly suitable when water is used frequently or the incoming water has a higher mineral concentration.Incoming water quality directly affects system performance, consumable life and the cost of producing pure water. 2. nLITE water-fed pole The pole carries water to the brush and allows elevated surfaces to be reached from the ground. The Unger nLITE range includes aluminium, Carbon Composite and different carbon fibre constructions with varying levels of weight and rigidity. The choice depends mainly on the usual working height, frequency of use and the level of rigidity required. For high-level work, Unger offers Ultra HiMod configurations designed for working heights of up to approximately 20 metres. 3. Water-fed brush The brush provides mechanical action on the surface while distributing pure water during washing and rinsing. Unger nLITE brushes are available with different bristle types, widths, swivel systems and water outlet configurations. The choice depends on the surface, the type of dirt and your usual working method. 4. Hoses, adapters and connectors Hoses carry water between the filtration system, pole and brush. Adapters, regulators and connectors complete the circuit and allow it to be adapted to the equipment being used. Before selecting a hose or connector, always check the diameter, coupling type and compatibility with the rest of the system. Benefits of pure water window cleaningAllows elevated surfaces to be cleaned from the ground. Can reduce the need for additional access equipment on many jobs. Allows routine cleaning without detergent when working solely with pure water. After rinsing, there is no need to remove the water with a window squeegee. Allows large exterior surfaces to be cleaned using a continuous washing and rinsing system. Can be used on windows, façades and certain solar panels, following the cleaning instructions for each surface.Which pure water system should you choose?DI: for certain usage levels and situations where using resin is appropriate. Nano: a hybrid nanofiltration and DI system for certain jobs without the need for an electric pump. RO: for frequent work, higher production requirements or water with a high mineral concentration.You should also consider the working height, required flow rate, available space for transporting the equipment and the number of operatives who will use the system.

nLITE Adapter for traditional tools
Unger adapter that adds a standard thread to the angle adapter of nLITE poles, allowing traditional tools — window washers, squeegees and scrapers — to be used instead of the pure-water brush. Converts the nLITE pole into a versatile telescopic handle for conventional high-level cleaning. Reference NLCLA.
€9.99
Euro thread adapter for brushes
Unger adapter that adds a Euro thread to the angled adapter of nLITE poles, allowing brushes with a standard Euro thread to be connected. Different from the NLCLA adapter for traditional tools — the NLTHR is specifically for cleaning brushes with a Euro thread. Compatible with nLITE poles. Reference NLTHR.
