ALASKA  [ Return towards  Equipment  ]

ALASKA is an environmentally friendly cold source that is particularly well 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 experience gained by AIR LIQUIDE in the field of cryogenic techniques, and the process's simplicity are your assurance of safety and reliability

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
• 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 is in this case allowed to cover a larger range of temperatures which can range between -100°C and +160°C.
