An infinitely controllable cleaning process that will gently remove, in a single operation, oil, grease, surface oxides and protective paint from precision engineering components
and delicate structures without damaging substrates or polished surfaces.
Why WASP?
|
• |
Environmentally acceptable - no dust is generated. |
|
• |
Intrinsically safe - no static or explosion hazards. |
|
• |
Uses inert materials - no toxic, volatile or chemically aggressive materials required. |
|
• |
Gentle water buffer action between surface and process media prevents peening of components. |
|
• |
Will highlight cracks in metal components. |
|
• |
Stripping, de-greasing and cleaning carried out concurrently. No pre-washing required. |
|
• |
Very fine plastic media can be used on thin metal sections, which minimizes distortion. |

Circuit Diagram
The basic elements of the system consist of a sump containing water and the process media - plastic grit (amino thermoset resin) or micro powder (aluminium oxide).
Plastic grit is mainly used when treating metal components; micro-powder for composites. The media, together with an oxide inhibitor and degreasing agent,
is circulated by a vortex pump to a process nozzle, from which it is discharges, and the water vaporized by compressed air at pressures of between 10 & 75 p.s.i.
After use, the mixture gravitates back to the sump, where the media is washed and the broken-down particles and debris are removed by a combination of cyclone, elutriation and magnetic separators.
Processing is carried out in recirculatory dedicated enclosures from small hand/automatic cabinets to large walk-in booths with robotic nozzle manipulation.
