SYRACUSE, NY, USA, March 18, 2025 -- Bluefors today announced a new, compact, high-performance, two-stage pulse tube cryocooler – the Cryomech PT205 – designed to support advanced scientific applications and superconducting technologies.

Launched at the APS March Meeting in Anaheim, California, the PT205 is a compact cryocooler that is both energy- and cost-efficient. A key feature of the PT205’s pulse tube technology is a lack of moving parts, resulting in increased reliability and longevity, and significantly lower vibration levels compared to traditional cryocoolers.

Low-vibration operation is particularly valuable in applications where even the smallest of vibrations can disrupt sensitive equipment or measurements. For example, the PT205 is ideally suited to the field of superconducting nanowire single-photon detectors (SNSPDs) – used to detect single photons, making them invaluable in quantum optics, communications, and other applications requiring precise photon detection.

Measuring just 11 inches (28 cm) in length and weighing 19 pounds (8.6 kg), the PT205 meets SNSPD needs by providing the necessary cooling power in a compact, highly customizable, energy-efficient design that can easily be integrated into limited spaces.

Developed by the Bluefors cryocooler research and development team at their production facility in Syracuse, New York, the new, compact cryocooler is engineered to provide substantial cooling power at low temperatures, ensuring reliable performance in demanding environments. It delivers more than 10 milliwatts of cooling power in the 2.5 K range while consuming only 1.3 kW of power at 60 Hz, making the PT205 an energy-efficient and cost-effective option – an essential consideration for long-term operations in scientific and industrial settings.

Rich Dausman, President of Bluefors Syracuse, said, “The PT205 answers the call for a reliable, compact, high performance, two-stage pulse tube cryocooler for the growing SNSPD market. offering an exceptional balance of performance, reliability, and cost-effectiveness for demanding cryogenic applications. The PT205 is the latest example of our proud tradition of listening and responding to the needs of our customers and the cryogenic community.”
