Pratt introduces novel metal-stripping service

East Hartford's Pratt & Whitney Co., best known for jet engines, has introduced a patented high-powered waterjet system it claims is an easier, greener way to strip chrome and other coatings from parts and machinery.

Pratt & Whitney Automation's new service, PurePulse, replaces the old techniques of chemical dips and powered grinding wheels to strip and clean metal surfaces, General Manager Jim Cooper announced Tuesday.

PurePulse is a commercially repackaged version of the same system Pratt uses to strip jet-engine parts for maintenance and rebuilding, officials said.

Pratt & Whitney Automation, based in Huntsville, Ala., are both part of United Technologies Corp. in Hartford.
