When liquid oxygen is needed on-site, fast, and with high reliability, Qdrive is the way to go! The US Navy is developing a new class of aircraft carriers, CVN-78, and has ordered Qdrive's acoustic-Stirling liquefaction technology for all on-board generation of liquid oxygen. Qdrive liquefiers produce automatically liquid oxygen within minutes of switch-on, replacing conventional equipment that require hours of manned operation before the first liquid flows. Procurement of the first proof and production units is underway, with CFIC-Qdrive constructing the liquefiers and Gas Equipment Engineering Corporation of Milford, CT integrating the system for prime contractor Northrop Grumman (Newport News).

Qdrive's largest cryocooler, model 2s362K, is to be configured with new coldfinger heads (developed for HTS service under a separate DoE program). In the CVN-78 service, three such heads are driven by a single pressure-wave generator to provide up to 1000 watts of cooling to provide more than 55 gallons of oxygen per day. Qdrive brings the combination of speed, efficiency, and robust motion and shock tolerance to this critical application.

Qdrive: Better in the Long Run!
