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.
