181 Steam at 180°C allow to degrease dirt also without the use of heavy chemical products. If they are necessary to speed up the washing task, it is very important to consider the cost of draining away dirty water. The danger of chemical products used is generally proportional to the effectiveness against increasing dirt tenacity. If we wash with the high-pressure cleaner we produce from 10 to 21 litres of polluted water, that must be collected and drained following the current regulation: in a single wash of a couple of hours 2,5 tons of dirty water is produced! If we wash with a steam generator, the most powerful machine produces 37 litres per hour, with the most part of the liquid that evaporates, with a two hour wash the remaining dampness and disinfecting product is very low! Analyzing all these subjects it is clear that in particular circumstances (lack of purification plant for water treatment), the steam generator is more advantageous of a high-pressure cleaner. On the other side, rinsing speed is the consequence to the delivery rate that hits dirt, so if only the washing phase is considered, high-pressure cleaner is faster. Steam can be considered water with a related dampness very, very low (superheated steam is just hot air and it doesn’t have a significant mechanical action…), with an outlet temperature much higher (180°C) than a high-pressure cleaner: this means that the mechanical power is lower than the one of water, but the degreasing power of steam is much higher. • Discharge valve: Allows a complete discharge of the boiler (not possible even through gun use). In this way it is possible to remove water and limestone residual inside the boiler and from the coil surface. This valve maybe opened only when the boiler is not hot, and it is recommended to accomplish regularly. • Unlimited autonomy: The boiler is refilled by a water pump that gets water from an external water tank. This system allows an unlimited autonomy, because it is not necessary to turn off the steam generator and wait a lower temperature to refill with water. An automatic control recharges the boiler when necessary. In some models there is an acoustic signal advising about low water level inside the water tank. • Integrated vacuum: Dirt is vacuumed inside a tank integrated in the machine • Multipurpose washable filter It combines all the advantages of the cartridge filter but with the plus that it can vacuum both dry and wet at the same time. It can be washed with tap water. • Foam system: the machine is equipped with connection for compressed air and pressure gauge for foam cleaning. Using the lance with the hose a thick foam can be produced that will stay on the dirty components, giving more effectiveness to the detergent. Dry steam cleaners - Steam vacuum cleaners
