High Pressure Washers

High Pressure Washers Cut Through It All

High pressure washers are designed to cut through just about any type of dirt regardless of its thickness or composition. It may require higher compression, hotter water or the addition of a detergent but there is very little that these incredibly powerful devices can’t strip free of its coating of grime.

Though their principle is a simple one, the results they produce can be nothing short of amazing. Just as effective when used to clean the floors and walls of some grimy factory as when hosing down the family saloon, high pressure washers offer their users a wide choice of options with which to meet an equally wide range of challenges with selection of units that vary in their pressure and temperature capabilities as well as in their total capacity.

Though dimensions and shapes may vary, the operating principle remains the same. Water in a tank undergoes compression by means of a suitable powered motor. A trigger releases the high power jet that is directed as required by means of a metal tube known as a wand.

Some high pressure washers also have a heating facility that is useful where some extra grease cutting power may be needed while others provide the means to introduce special solvents or detergents into the cleaning jet to add even further to this effect. A selection of interchangeable nozzles may be attached to the wand to provide broader or more focussed jets as determined by the surface to be cleaned.

These devices can generate considerable pressure and could cause serious injury if used carelessly. High pressure washers for use in the home are inherently less powerful than their industrial cousins but should still be handled with due concern for the health and safety of those in range.

Vehicle washing is a very common application for these devices and one at which they excel. From the children’s BMX bikes, to giant MAC trucks they make child’s play of these tasks and are able to reduce the hours of, often back-breaking labour required when using manual methods, to a matter of minutes.

As well as speed and efficiency, high pressure washers also offer economy, using just a fraction of the volume of water that would be required when using a standard hose connected to a tap.

A brief History of High Pressure Cleaners

Although now available from a number of different manufacturers, the pressure washer was the brainchild of a man whose company is widely recognised today, by users all around the globe, as a synonym for this ingenious cleaning device.

Its inventor, Alfred Kärcher, began his business in pre-war Germany and, at that time, its focus was not on high pressure washers but on the design of immersion heaters used to smelt salt. Nevertheless, sound products and reliable service led to a prosperous business within the five years from 1935 to 1940. In 1950, just nine years before his death, the elderly Kärcher designed and produced the world’s first industrial cleaner to perform its task by using water under pressure.

Quite soon, the company, abandoned its industrial furnaces in favour of a core business devoted to cleaning equipment including the, by then, very popular high pressure washers. In the intervening years, this product has undergone many refinements, each of which has provided another significant milestone in the evolution and optimisation of pressure cleaning technology. In the process, the Kärcher company as earned itself the reputation of an almost unparalleled innovator. Should anyone hold any doubts about this; they should be aware that the company has registered more than a thousand patents on new products, processes and new applications of technology within the cleaning industry.

Its high pressure washers have been joined by many other example of efficient cleaning equipment since their invention and the last half decade of the company’s history has proved to be particularly prolific with around 85% of its entire product portfolio having been during less than 7% of its total existence.

Among these new products are stationary variants of their pressure cleaners. They include cold water units that lack any heating facility but can handle feeds of up to 80°C, electric flow heaters for use where oil or gas burning units could carry the risk of fire or explosion and hot water units that can deliver a jet at close to boiling point.
