产品概述 Product Overview

This Cryocooler is a GM-JT composite system. The helium gas is precooled from the conventional GM cryocooler and then entered into the JT cryocooler to achieve a low temperature of 1K. According to the different needs of users, JT cryocooler has two options: open cycle and closed cycle. In open cycle, the helium consumption at the lowest temperature of the cryocooler is 0.7SLM, and the operating time of conventional gas cylinders can be up to 6 days. In closed cycle, coupled with additional gas pipelines and filtration systems, allows helium to be reused, further reducing the cost of cryogenic systems.
