Better Engineering - Washing System for GE Aero Engines

Better Engineering : 19 June, 2007  (Company News)
Automated parts washing system for G.E. Aircraft Engines to clean jet engine components.
Replace solvents with a water based unit that meets G.E.'s cleanliness


G.E. is one of three companies that dominate world jet engine production. The other two companies are Pratt & Whitney and Rolls Royce. All the parts made for a jet engine have to be cleaned during and/or after the manufacturing process.

All parts were being cleaned in vapor degreasers which had to be shut down by a self-imposed deadline. The directive was to get away from solvents completely, and use aqueous systems. This was a hugely complex endeavor given the importance of cleanliness and the fact that aqueous cleaning had never been proven in their industry.

Work closely with their engineers, studying each part individually. For each application, tests were run and the results analyzed until G.E. was satisfied with the performance. The machine shown is one of many aqueous cleaning systems now in place.

A stainless steel F-4000-P with an ARC-22 rinse tank and a hot air drying system. The air drying manifold (you can see the green hose leading to it) can be slid up and down to get as close to the parts as possible. The system has a 'PCS' control panel further enhanced to meet G.E.'s plant specifications.
