 Sumitomo Heavy
Industries has expanded their product line yet again with the addition of a
two-stage pulse tube cooler. With a base temperature of below 3.0 K, this
new product extends the range of possible applications for Sumitomo closed cycle
refrigerators to include low-temperature, low-vibration applications. The
pulse tube cooler has no internal moving parts, so has inherently low vibration
levels.
Full specifications are listed below.
