These units cool the reactor by circulating a heat transfer liquid cooled by liquid nitrogen. Cryogenic replaces the need for CFC and is particularly suited to very low temperatures. Its high available cooling power can safely control exothermic reactions.
As well these batch-type operations usually require heating the reactor. Therefore the company offers a heating module to warm up the heat transfer liquid, by using low pressure steam. This allows regulation through a large range of processes from –100°C to +160°C with a specific silicon oil.
The company offers seven standard Alaska cooling units varying form 5 to 100 kW. These compact lightweight units can be easily integrated into a production line.
In addition, the company provides a turnkey solution to customer needs (significantly higher power, presence of a specific thermal fluid, etc.).
Their long experience with cryogenics and the simplicity of the process guarantee safety and reliability of their units.
