1. Main Features

The liquid nitrogen recondensing refrigerator is a hybrid refrigerator formed by combining conventional liquid nitrogen and electric refrigeration. It is a revolutionary breakthrough in the field of cryogenic cooling detectors.

This product uses a Stirling thermoacoustic refrigerator as the main working part, so that the temperature of the cold end is lowered to the temperature of liquid nitrogen, so that the gaseous nitrogen in the Dewar is condensed into liquid nitrogen, and the recycling of liquid nitrogen is realized.

?The working life of the refrigerator is not less than 100,000 hours;

?The detector can be continuously refrigerated for 12 months without the need to replenish liquid nitrogen;

? The 30-liter liquid nitrogen tank, after being filled with liquid nitrogen, will ensure the low temperature environment of the detector in the event of a power failure, and ensure that the system can run normally for 10 consecutive days;

?Stirling electric pulse tube refrigeration;

?The motor recovers the volatilized nitrogen and compresses it back to liquid nitrogen;

?The software monitors the working status of the refrigerator and monitors the working status of the system in real time;

?Customized interface design can match all kinds of high-purity germanium gamma spectrometers.
