LN2 Pre-Cooling Loop

Cryogenic Measurement System Option

The Liquid Nitrogen (LN2) Pre-Cooling Loop can be pre-installed in our systems at the factory to achieve faster cooldown.

By engaging the manually operated LN2 Pre-Cooling Loop with an external source of liquid nitrogen, it is possible to reduce cooldown time by ~ 40% in a standard system.

The operating temperature range for the Pre-Cooling Loop is between room temperature and 80 kelvin. This option requires supervision during operation, and a large volume of LN2.
