Commercial Pressure Washer
A commercial pressure washer has become an important part of the cleaning programme in many industrial sectors. The variations of size, duty, type and accessories are quite mind boggling, and can be confusing when selecting the correct appliance. The choices are various – hot or cold water? is a steam option required? is pressure or flow rate more important? what type of power? these are some of the questions to be answered and these are discussed below.
Commercial Pressure Washer – Selection Options
The cleaning effect of a commercial pressure washer is achieved through the water penetrating the dirt to wash it away. This may not be adequate for certain types of deposit such as oil or grease where a hot water pressure washer would be a better option, than a cold water version, as the heat in the hot water assists in degreasing the surface.
Where additional cleaning power is required then a hot water pressure washer with a steam facility is an option. The steam is created by reducing the pressure in the machine but letting the burner run until the water turns to steam. This is a useful addition, but if steam is regularly required as a cleaning medium then a purpose made dry steam cleaner would be better.
Pressure or Flow Rate
It is a common misnomer that pressure is the most important factor in a pressure washer. Water applied to a surface at high pressure does offer deep penetration but restricts the operation to a small area. A washer with a greater flow rate is more useful for cleaning large flat areas where the washing can be carried out more speedily. See our pressure washer glossary for more information
Type of Power
A pressure washer is normally electric powered but this is not always suitable as the machine may be required to be used off site where electricity is not readily available. In this case a diesel or petrol pressure washer is an alternative, possibly with its own water tank for completely independent cleaning.
