Refrigeration Tools for Thermoregulation (ALASKA™)  [ Return towards  Equipment  ]

ALASKA™ units are environmentally friendly cold sources that are suited to very low temperature conditions e.g. steroid synthesis in alcohol or ammonia mixes. Its high level of available cooling power monitors the exothermic level of a reaction in complete safety, for example penicillin synthesis using 6-APA.

The Heat Exchanger

This is highly efficient, with optimal consumption of liquid nitrogen. Our proprietary, patented cryogenic heat exchanger enables you:

• To obtain very low temperatures (practically to freezing point) of the heat transfer fluid, without any risk of clogging; and
• To minimize charge loss within the body of the exchanger, which significantly reduces liquid nitrogen consumption

Cooler Groups - Reheating

During certain discontinuous operations, the reactor must be heated. A reheating module for the heat transfer fluid, which often uses low-pressure steam, can then be combined with a cooling module. Regulation in this case is allowed to cover a larger range of temperatures which can range between -100°C and +160°C.  

Specifications

• ALASKA™ units have a nominal cooling power of between 5 and 100 kW.
• Our units are well suited for intermittent cooling, as is the case for batch-type chemical processes.
• ALASKA™ units are compact, noiseless and compliant with reduced sparking standards
• Fast installation start-up.
• Extremely low maintenance.
