Cryogenic Recirculating Chillers: Advanced Cooling for Diverse Applications

Cryogenic recirculating chillers are sophisticated cooling systems that utilize liquefied cryogens such as liquid nitrogen (LN2) or liquid carbon dioxide (LCO2) to achieve temperatures as low as -196°C (-320°F). These chillers are compact, portable, and designed to cater to both ultra-high and variable capacity cooling applications.

Functionality and Design
Cryogenic recirculating chillers operate by circulating a heat transfer fluid, which is cooled by the cryogen. The fluid absorbs heat from the process or device being cooled and returns to the chiller to be recooled. This cycle ensures a continuous and stable supply of cold fluid, providing precise temperature control.

Key Features of Cryogenic Recirculating Chillers

Low Temperatures: Capable of reaching ultra-low temperatures, making them suitable for specialized applications.
Compact and Portable: Designed for easy transportation and setup in various locations.
Automatic Cryogen Supply Adjustment: The chiller’s control system automatically adjusts the supply of LN2 or LCO2 based on the cooling requirements.
High Cooling Capacity: Capable of handling high heat loads, making them ideal for industrial processes.

Applications of Cryogenic Recirculating Chillers
These chillers find use in a multitude of applications across different industries:

Defense and Aerospace: For cooling sensitive equipment and systems.
Chemical Processing: To maintain precise temperatures in chemical reactions.
