SHI Cryogenics Group Releases Highest Capacity 77K Cryocooler to Date
New CH-160D2 Cryocooler Increases Cooling Performance by 300% Compared to Existing Models
The SHI Cryogenics Group has added a new model to its line of Gifford-McMahon (GM) Cryocoolers with the introduction of the CH-160D2 77K Cryocooler. The CH-160D2 is SHI’s highest-capacity 77K Cryocooler to date, with a first-stage capacity of 525/630 W at 77 K (50/60 Hz).
The CH-160D2 introduces a unique design that combines the best features of SHI’s CH and RDK Cryocooler series. It utilizes Whisper® technology for quieter operation, as well as Displex® pneumatic drive technology, limiting the number of wear parts in the refrigerator. Its new gas-balanced valve design decreases torque and, along with its patent-pending gas-energized seal, reduces overall wear and tear. Additionally, the CH-160D2 showcases both a new stem drive and a novel heat exchanger designed to increase efficiency.
The CH-160D2 is ideal for several applications, including liquid nitrogen generation and liquefaction; clean energy technologies; and high temperature superconducting applications such as cables, fault current limiters, wind turbines, ship motors, and accelerator magnets.
The CH-160D2 is RoHS and CE compliant, and operates with two (2) F-70 compressors, or one (1) F-100 compressor at a slightly reduced capacity. Both compressors are three-phase, indoor, water-cooled units available in both high and low voltage models. All Freedom® series compressors utilize highly reliable scroll compressor capsules, have an industry-leading 30,000-hour maintenance interval, and are designed exclusively to deliver high pressure, oil-free helium to cryogenic refrigerators.
Like all SHI cryocoolers, the CH-160D2 is competitively priced and offers users high quality and proven reliability. The SHI Cryogenics Group has the most extensive installed base of cryocoolers worldwide and supports its customers with a global service and support network of twelve offices and numerous representatives.
