4K pulse tube Cryocooler series
The RP-062B Pulse Tube Cryocooler is one of SHI’s smallest 4K Pulse Tubes, with a second-stage capacity of 0.5 W @ 4.2 K (50/60 Hz).  It is an integrated unit that operates with a water-cooled helium compressor.

SHI’s 4K Pulse Tube Cryocoolers embody leading-edge technology and provide low vibration, high reliability and low maintenance requirements.

They are uniquely designed with no moving parts inside the cold head. In addition, they feature an optional separated valve unit to further reduce vibration, enable operation in higher magnetic fields and ease maintenance requirements. SHI Pulse Tube Cryocoolers provide a stable low-temperature solution for sensitive measurement and analytical applications.
