Selecting a Pressure Washer
Selecting the correctly sized machine from the huge range of pressure washers available can be daunting. The selection criteria are based on the type of job the appliance is required for. An example would be oil or greasy deposits which are adherent may require a high pressure to remove them, however a large hard surface area requires a lower pressure but a higher water volume. Consideration should always be given to the duty that the machine will be required to give to make sure you select the correct machine.
Types of Pressure Washers
The sophistication of pressure washers has developed over the years and there is a lot of choice. Hot water washers as well as cold are now available which are more effective if degreasing or disinfecting are required. The other advantage is that because hot water cleans better than cold, lower pressures can be used. Pressure washers can be portable or static and there are advantages to both:
- Portable Pressure Washers have an advantage as they can be moved where the cleaning is required. If the washer powered by electricity the portability is obviously restricted by the length of the power cord. Some pressure washers are available with their own power source, such as a diesel engine and can be moved around the site or off site for remote cleaning.
- Static Pressure Washers are a static wash system for premises where there is a regular requirement for hot water pressure cleaning. This would useful say in a transport company where a static jet wash facility could be used by a variety of operators at different times or in a small food processing plant where a cabinet mounted pressure washer would enable efficient cleaning. This type of stand alone hot pressure washer can be attached to a ring main system for one or two operators to access at various points to clean around the premises.
