Since 1981, ULVAC CRYOGENICS INC. has manufactured cryopump systems for the semiconductor, LCD and related vacuum industries. Our experience in these competitive markets has taught us to build highly reliable and powerful 2-stage Gifford-McMahon refrigerators. We have leveraged that experience and developed a 4K cryocooler, utilizing our own proprietary technology, which can be used for laboratory or industrial applications to eliminate the need for liquid helium. This compact unit features excellent thermal stability and low input power.
