A high-performance hybrid pulse tube cryocooler that uses dual-opposed gas bearing pistons, dual ambient displacers for phase shifting and recovering acoustic power. It combines the advantags of both pulse tube cryocoolers and Stirling cryocoolers and leads to a cryocooler with high reliability, high efficiency and low vibration at the cold head. This product is mainly designed for sensors in measuring instruments that require a low-temperature environment and can also be used in small gas liquefaction applications.

• Dual-opposed gas bearing pistons driven by linear motors, long lifetime.
• Pulse tube cold finger integrated with dual-opposed ambient displacers, acoustic power recovery and high efficiency.
• Integral configuration, easy to use.
• Motor stator isolated from gas chamber, long lifetime and high reliability.
• Maintenance-free.
