As industrial refrigerants come under increasing environmental and regulatory pressure, the manufacturing sector is looking to natural alternatives for a many applications. Compressor cascade technologies that use natural refrigerants offer a way to achieve effective process cooling while eliminating regulated industrial refrigerants.

Options for the implementation of a freeze dryer refrigeration system, either mechanical or cryogenic, can be specifically adapted to individual process and product requirements. The two main considerations when selecting a suitable refrigeration solution are refrigeration temperature and cooling capacity.

In a white paper, GEA describes technology that employs natural refrigerants and complies with the 2015 F-gas regulation. The system for freeze dryers incorporates carbon dioxide cooling.
