Liquid nitrogen circulation cooling device (refrigerator cooling type) [Manufactured by Suzuki Shokan]

Continuous cooling of heat-generating elements such as spectrometer crystals and HTS coils is possible. There is a track record of supplying cooling for spectrometers and shield refrigeration for current limiters.

This is a device for stably supplying liquefied nitrogen to test specimens at temperatures between 67K and 85K while remaining in liquid form. The temperature of the liquefied nitrogen is controlled using a refrigeration unit and an accompanying heat exchanger. The circulation amount of the liquefied nitrogen can be adjusted with a circulation pump. Our company offers various applications using refrigeration units. 【Features】 ◯ Continuous cooling of spectrometer crystals, HTS coils, and heating elements is possible. ◯ No need for refrigerant replenishment. ◯ A mechanism that transports sub-cooled liquid nitrogen from the refrigeration unit to cool samples using a low-temperature pump. ◯ The device can be installed away from the test specimen. ◯ Continuous operation can be safely conducted with various interlock mechanisms. ◯ Flow and temperature control are possible via the operation control panel, which also includes continuous circulation monitoring, alarm functions, and emergency stop functions. ◆ There is also a "liquid nitrogen cooling type" for the liquid nitrogen circulation cooling device. ● For more details, please contact us or refer to our "Cryogenic Equipment Product Catalog" available on the download page. ◎ As of April 1, 2019, the comprehensive catalog has been revised.
