In a hot water pressure washer the design inlet temperature should not be exceeded as it may affect the seals in the internal machinery. The size of the motor that drives the pump to produce the water pressure. The motor size is normally expressed in Kw for an electric washer and HP for an engine driven version. The motor must be correctly sized to match the pump to ensure optimum performance. On cheaper machines the pump may be smaller than the ideal size meaning it has to work harder to create the required flow and pressure and as a consequence will not last as long.
Pure Water Cleaning Cleaning Equipment for Pure Water Cleaning. Water is a naturally impure liquid and these impurities can interfere when using it for cleaning as microscopic deposits can cause streaks or marks and windows for example may not look as clean as they might. Pure water has all the impurities removed by a process called reverse osmosis and because water is naturally impure it wants to return to its natural state. This means that when pure water is applied to a surface it will absorb the deposits from it leaving the surface clean and streak free.
CST™ Continuous Steam Technology The ONE Plus™ steam cleaner was designed with a two-tank system. This technology means the water tank is not under pressure and can be refilled at any time eliminating downtime. Stainless steel boiler High-grade stainless steel is TIG welded together with a robotic welder to ensure the quality of the most solid and durable boiler on the market. This is why Dupray provides a lifetime warranty on its boilers – the heart of any steam cleaner.
