Cold Water Pressure Washer

The effectiveness of the cleaning power of water when under pressure is well known and is apparent from the example of a simple garden hose. When the aperture on the nozzle is reduced the water is emitted in a narrow, more forceful jet because of the pressure that is built up

Principles of a Cold Water Pressure Washer

A cold water pressure washer works in a similar way to the garden hose analogy except that pressure is additionally applied by means of a mechanized pump which expels the water at an enhanced rate. The water flow is controlled through a trigger mechanism which means the water can be shut off at any time. The cleaning power of a pressure washer is dependent not only on the pressure exerted but also on the volume or flow of water passing through it. For large areas for example there may be a requirement for a high water volume with a lower pressure whereas for a small area of stubborn build up a higher pressure may be necessary. There are a variety of duties required of a pressure washer and there are a range of models available on the market for all jobs.

Types of Cold Water Pressure Washer

Pressure washers vary in size from smaller domestic machines with a water flow of 6 litres per minute and a pressure of 100 bar up to machines with twice these capacities and more. Cold water pressure washers can be powered by electricity or independently driven by a petrol or diesel engine. They can be portable or static and plumbed in where there is a regular clean up requirement, and if portable and independently powered they can be used anywhere where clean up is required. There are numerous attachments for cold water pressure washers which are designed for specific purposes. For instance an extending lance for high level cleaning, or a wrirlaway attachment which uses a revolving spay bar for cleaning driveways and patios.
