Today with the current covid crisis, ultra-low refrigeration has been brought to the forefront. But it is not only important for vaccine storage, it is vital to other medical, industrial and food processing industries. And due to environmental concerns transitioning from current refrigerants to the next generation low GWP is a priority and will require evaluation. Beyond system and compressor reliability other concerns including lubricants and material choice need to be considered. This seminar will discuss the different types of ultra-low refrigerant systems and the importance of lubricant and material selection.
