Fixed installations are very convenient as they are setup with a permanently connected water supply and are available almost instantly, with the flip of a switch.  Piping pressurized water throughout a plant using an array of pipes or hoses, switches and valves allows for multi-stations to be used individually or at the same time. For even more convenience these systems can be setup with an automatic stop-start system which starts when you pull the trigger and stops when you release the trigger.

Many plants will have a dedicated pressure wash pad setup with a catch basin to recover and recycle wash water.  Some installations require a portable cart and wheel structure which can be plugged into various wash stations, some require multiple pumps and other high pressure cleaning systems require stationary mount for a central cleaning system. High pressure cleaning systems are fitted with a primary and secondary pressure relief valve for safety with other high pressure accessories included as required.
