• Closed Circuit Thermostat CCG-4K

  Because of the scarcity of helium resources in China, we have long relied on imports, while the United States, as a major helium resource country, regards it as a strategic reserve and restricts its exports, leading to a continuous rise in the price of liquid helium. This price increase, as well as import restrictions, had a serious impact on the progress of our scientific research endeavors. As a result, the closed-cycle refrigerator was born. Its most typical feature is that it eliminates the need to consume expensive refrigerants, making the cost of cryogenic access dramatically lower. The closed-cycle thermostat has become the most commonly used sample cooling system in laboratories.
