New Co-Ax Coldheads, More Cold, Less Weight
Upgraded 132-class coldhead now 25W @ 77K, Smaller and Lighter, too.
Date: 26-Feb-2010
CFIC-Qdrive has introduced a new co-axial coldhead for its 132-class cryocoolers (2s132K), with more than 20% improved performance and 1/3 mass reduction, compared to the popular U-tube coldhead it replaces.  The new coldhead fits in a smaller dewar neck (55 mm); still operates in all orientations; and is available in either close-coupled or FAR (flexibly-attached remote) configurations.  Like all Qdrive coldheads; the new 132 co-ax has no moving parts or dynamic seals, is balanced, silent, and maintenance-free.  Pricing is unchanged.  The first recipient-user of a Qdrive cooler with the new coldhead is a U.S. National Laboratory; which will use it for maintaining ultra-pure liquid xenon as part of a dark-matter search program.  Contact info@qdrive.com for details!
