Detergent Systems on Industrial Pressure Washers

Low Pressure Detergent Systems

On a Low Pressure Detergent System the detergent is injected into the delivery hose connected to the on/off gun wash-lance. Detergent therefore does not come into contact with any of the pump or key components of the Industrial Pressure Washer.

The control for the detergent is made via a valve on the operator lance and as such the control of the detergent can continue uninterrupted without the need to go back to the Pressure Washer.

The operator is required to drop the pressure to eject detergent the Pressure Washer Operators feel that they are not experiencing the normal method of "Pressure Washing." As a result operators can apply a coating of detergent as quickly as possible so that they can return back to High Pressure to experience the "normal" feeling of "pressure washing". In doing so the operator automatically utilises the detergent exactly as it should be used - applying a coating before switching back to the high pressure operation.

As the Pressure Washer picks up detergent on the outlet side of the pump, this means that when the detergent runs out, there are no detrimental effects on the Pressure Washer. The Washer will continue to pump water operating as normal until the detergent is replenished.

High Pressure Detergent Systems

On a High Pressure Detergent System the detergent is injected at the pump and passes through key components and fittings of the Power Washer, including the pump and heating coil, before finally reaching the on/off gun wash-lance.

As detergents are corrosive, they act as a catalyst on wear and tear of components including pump materials and pump heads; seals and valves etc. Costly parts such as heating coils are also affected by detergent which can significantly reduce their longevity due to increased corrosion.

The control of detergent is normally on the Pressure Washer and requires operators to return to the Washer to switch it off. After doing so, it takes a few moments for the line to clear through which results in wastage of detergent - the biggest consumable cost after purchasing a Pressure Washer.

A High Pressure System is often misused and abused when continuous application is permitted during "Normal Operation". This means Pressure Washing is carried out with detergent continuously switched on instead of only a "coating" or "film" being applied.

The control for the detergent is made via a valve on the operator lance and as such the control of the detergent can continue uninterrupted without the need to go back to the Pressure Washer.
