LN-C Condensing Liquid Nitrogen Chiller

Product Description

LN-C Condensing Liquid Nitrogen Chiller is a revolutionary breakthrough in the field of cryogenic cooling detectors, a hybrid cooling machine using conventional liquid nitrogen combined with electrical refrigeration. lt uses a Stirling thermoacoustic electric refrigerator as the main working component to bring the cold end temperature down to liquid nitrogen temperature, thus condensing the gaseous nitrogen in the Dewar to liquid nitrogen and realising the recycling of liquid nitrogen.

Functional features

A chiller with a working life of no less than 120,000 hours
Continuous cooling of the detector for up to 12 months with power supply without no need of replenishment for liquid nitrogen
30 liter liquid nitrogen tank, guarantees the detector's cryogenic environment with full liquid nitrogen in the event of a power failure, ensures 10 days of continuous normal operation of the system.
Stirling electric pulse tube cooling.
Motor recycles evaporated nitrogen for compression back into liquid nitrogen.
Software to monitor the working status of the chillers and to monitor the working status of the system in real time
The interface is customized to match all types of high purity germanium gamma spectrometers.

Key benefits

Compared to liquid nitrogen refrigeration, recondensation refrigeration ensures reliable performance of liquid nitrogen refrigeration, avoids frequent refilling of liquid nitrogen, ensures long-term operation of the detector at low temperatures and saves on liquid nitrogen material and manpower costs. Compared to electric cooling, recondensation cooling uses liquid nitrogen as the medium, avoiding direct contact between the detector and the chiller and greatly reducing the impact of vibration on detector performance. At the same time, it solves the major drawback of losing the cooling capacity of the electric cooler in case of power failure ensuring that the low temperature environment of the detector can stil be maintained in case of power failure, so that it can be quickly used when power is restored.

Application areas

For use with high purity germanium detectors
For use with other scientific instruments operating in the liquid nitrogen temperature zone
