Closed-cycle Cryostat
Introduction
Closed-cycle Cryostat provided by Dexing Magnet is a variable temperature low temperature platform based on Japan SHI 4K refrigerator, which is used for magnetic, optical and electrical measurement in low temperature environment. It is a precision instrument that uses a refrigeration compressor or other refrigeration device to reduce the temperature of the system and delivers the cooled liquid or gas to the system through a circulating pump. When the temperature of the system reaches the set value, the thermostat will automatically shut down the refrigeration device and maintain the temperature of the system by heating the device.
The features of the Closed-cycle Cryostat ·
2.1 Accurate temperature control: Closed-cycle Cryostat is equipped with a high-precision temperature sensor and control system. It can accurately control the temperature of the system within the set range, usually with an accuracy of ±0.1℃.
2.2 Wide temperature range: The temperature control range of Closed-cycle Cryostat is generally -40℃~200℃, which can meet the needs of different applications.
2.3. Efficient cooling effect: advanced closed-circuit refrigeration technology is adopted to ensure that the cooling effect is stable and lasting during a long period of operation. Its internal use of efficient refrigeration system, through the accurate temperature sensor and control system, to achieve rapid response to the temperature and accurate control. Whether it is a scientific experiment requiring deep freezing, or an industrial process requiring minimal temperature fluctuations, Closed-cycle Cryostat can meet its needs.
2.4 Safe and reliable: the Closed-cycle Cryostat has perfect safety protection measures, including overload protection, short circuit protection, overvoltage protection, etc., to ensure the safety of the equipment during operation, and to prevent the system from overheating or undercooling.
2.5 Good compatibility: It can be seamlessly connected with various experimental instruments and process equipment to achieve precise temperature control. Whether it is low temperature reaction in the research laboratory, material performance testing, or freeze drying, low temperature storage and other processes in industrial production, Closed-cycle Cryostat can provide you with a reliable solution.
