How to turn an older refrigeration system in an existing freeze-dryer into a new environmentally friendly cooling system.
In the fight against climate change, the pharmaceutical industry is challenged to reduce its carbon footprint. Cooling systems used in industrial freeze dryers are typically a high contaminant due to the presence of high global warming potential (GWP), HFC refrigerants or the use of a huge equivalent of energy consumption such as Liquid Nitrogen (LN2) technology. This case study explains the retrofitting of a new cooling system in an existing freeze dryer, developed to be environmentally friendly and energy efficient using a long-term and commercially available solution.
