LN2-COOLED FLUID CHILLER SYSTEMS - CRYO CHILLERS
Portable Process Chillers for Ultra-Low Temperatures and Rapid Cooling
Thermonics Cryo Chillers use liquefied cryogens (LN2 or LCO2) to cool heat transfer fluids with a proprietary cooling technology, delivering low and ultra-low temperatures and rapid transitions rates to a test device or process.
Cryo Chillers are compact, portable systems ideal for both ultra-high and variable capacity cooling applications where supply of LN2 or LCO2 is automatically adjusted by the chiller’s control system to meet the specified cooling requirements.
Cryo chillers are used in an assortment of industrial and commercial applications including: Defense, Aerospace, Chemical, Semiconductor, Pharmaceutical, Automotive, and Medical. In the right applications, a cryo chiller is a simplified and more cost effective cooling solution delivering a high ratio of capacity to system footprint.

Pros and Cons of an LN2-Cooled Chiller
Pro: Highest capacity cooling, up to 30 kW cooling power
Pro: Variable, on-demand cooling when needed
Pro: Extremely fast temperature transition rates
Pro: Smaller footprint than compressor-based chillers
Pro: Less expensive purchase price than compressor-bases chillers
Pro: Proprietary technology prevents freezing of heat transfer fluids
Con: LN2/LCO2 consumption adds long term costs
Con: LN2/LCO2 requires ventilation
How an LN2-Cooled Chiller Works
Liquid nitrogen (LN2) is supplied to a heat exchanger where it cools the heat transfer fluid. The heat transfer fluid is continuously circulated in a loop between the heat exchanger and the heat load. Heat from the heat load is continuously transferred to the heat exchanger where is it expelled with the gaseous nitrogen (GN2) exhaust.
