Refrigeration system for freeze drying
In pharmaceutical and biotechnological industries, freeze drying is a critical process for preserving sensitive materials. Traditional refrigeration systems often involve toxic and environmentally harmful refrigerants, creating challenges in sustainability and safety.
Eco-friendly air-based refrigeration for ultra-low temperatures
The KryoAir from IMA is an innovative refrigeration system that uses air as a refrigerant in freeze dryers. This technology is based on a series of compression, cooling, and expansion steps of air, which can be cooled to temperatures as low as -100°C. Comprised of an expander integrated with a compressor, a primary cooler for heat dissipation, and a heat-recovery heat exchanger, the KryoAir system ensures efficient refrigeration with minimal environmental impact. It combines a novel thermal energy storage system to handle peak heat demands, which is compact and has no moving parts. This system is compliant with environmental regulations and avoids the ozone depletion and global warming impacts associated with conventional refrigerants.
