Why use a Hot Water Pressure Washer?

A hot water pressure washer is ideally suited to the removal of oily or adherent dirt in the shortest time possible. Depending on the type of dirt, hot water can be up to 50% more efficient than cold water and has a shorter drying time. An additional advantage of a hot water pressure washer over a cold water version is that there is a reduction in the chemicals used, which lowers the cost of cleaning. These machines are used in a variety of industries such as agriculture, food and building, because of their ability to deal with oily dirt and fats as well as ingrained dirt such as that found on building equipment.

A pressure washer is an integral part of a cleaning regime in an industrial environment. The efficacy of the cleaning power of water when it is applied under pressure is well known and is evidenced from an appliance as simple as a garden hose. Sometimes the application of cold water to a dirty surface may not be enough, even with the addition of detergent, to clean to the required standard. If this is the case, then a hot water pressure washer is probably the answer.

How a hot water pressure washer works

The principle of a pressure washer is that water enters the hot water pressure unit where it is pumped through a cleaning lance and expelled on to the surface to be cleaned. In a hot water pressure washer there is the additional feature of an integral boiler to heat the water. The flow of water is controlled by a trigger mechanism on the cleaning lance, and the configuration of the spray is determined by the adjustment of the nozzle at the end of the lance. An additional facility with some hot water pressure washers is the ability to use steam as an extra cleaning medium for stubborn dirt. The steam is created by reducing the water flow rate and allowing the heater top raise the temperature of the water above 100°C, to around 140°C, which gives additional cleaning power.

Different types of hot water pressure washer

A hot water pressure washer is available in a variety of forms. At its basic level it is a small unit linked to mains electricity by cable. This is sufficient for light duty cleaning and provides a basic cleaning service. From this basic unit there are a series of larger machines for heavier duty, up to large trailer mounted machines with their own power and water supply.

Hot water pressure washers are often portable, but where a regular clean up is required they can be static with pre set controls, to ensure the operators use it correctly. A more sophisticated application uses hot water pressure washers as part of an integrated cleaning system, where cleaning lances are used by linking off a ring main system, which has water being pumped through it. This is known as a centralised cleaning system and is often used in food factories where regular clean up is essential.

There are many things to consider when purchasing hot pressure washers or any other type of cleaning equipment, where cost has to be set against efficiency.
