New refrigerants continue to dominate the conversation in the world of compressors as the sector deals with the regulation-induced demise of hydrofluorocarbons (HFCs) and prepares for the growth of hydrofluoroolefins (HFOs), hydrocarbons (HCs), and natural refrigerants, such as carbon dioxide (CO­2).

Several leading compressor manufacturers weighed in with insights and advice for contractors and technicians as they learn how to work safely with the equipment utilizing these so-called alternative refrigerants as they transition into primary refrigerant choices.
