The storage and transportation of LNG, liquid nitrogen and liquid oxygen, etc., generally have boiled-off gas (BOG) issues. To re-condense them for both economic and environmental reasons, cryocoolers with relatively large cooling capacities are needed. The requirements for these applications are long-term reliability, high efficiency, and robustness. Lihan kW-class pulse-tube cryocooler adopts co-axial cold-head and dual-opposed linear motor configuration and provides the benefits of high-reliability, high efficiency and easy operation.
