The optional passive balancer will further reduce cold head vibration for sensitive applications. Both the cold head and wave generator can be mounted in any orientation. Using gas bearings in the pistons as well as the displacer, the DS is able to offer improved reliability over flexure bearing technology. The DS 2.4 was designed to provide high heat lift with excellent temperature stability in an efficient manner over the lifetime of the product.
