You will need an injection system of one type or another. If you wish to wash a small helicopter engine, then you may only need a small portable hand held lance or ring with a pressurised container and an atomising nozzle. For a large fan engine, a ring that will wash the engine core will be be required, while the fan is clamped. The washing rig will need to be portable and contain a tank, pump and valves. For industrial engines there are separate fixed nozzle rings for off-line and on-line cleaning. There are also fixed/portable washing rigs which may be fully automated. We do not manufacture injection systems but we can recommend manufacturers who produce efficient systems.
