Cryocooler XV

Cryocooler XV

The Cryocooler XV series is a fully automatic, high pressure, super cooled liquid nitrogen cooler designed to remove heat from a load via a closed circuit.  The Cryocooler XV is the full-featured automated version of our system allowing complete flexibility in remote operation.  The Cryocooler XVm provides users familiar with manual cryocoolers all the performance of the XV but in a more cost effective package.

The Cryocooler XV series is particularly suited to cooling monochromator crystals.  It is possible to optimise the cryocooler settings for your specific cooling and stability requirements.  Flow rate, pump frequency and pressure can all be independently adjusted to achieve thermal and mechanical stability at the crystal.

Industry Leading Performance

The  XV has been designed and developed with the specific goal of creating the best performing cryocooler on the market.  As a result, the XV features industry-leading pressure stability, operating pressure and cooling power.
