The UP8497 is the smallest 80K UP cooler currently available, and is equipped with a displacer designed to fit into a standard Thales 1/4″ IDCA dewar bore.
The UP-LS series offers a comprehensive and versatile range of Linear Stirling coolers especially designed for cooling detectors in thermal imagers and IR sensors. Several of these cooler types are standard equipped with a patented thermal transfer block (Heatstop) in the cold finger, which reduces the required heatsink capacity at the warm end of the cold finger. The linear compressors can all be combined with several free displacer cold fingers.
The manufacturing of the clearance seal bearings of our split Stirling coolers is performed in-house with an accuracy of 1 µm or less over the full length of the bearing. This very accurate initial match between piston and liner adds significantly to the cooling efficiency, while improving the production reproducibility and cooler.
