Interested in learning how to use carbon dioxide refrigerant safely and effectively? The International Institute of Ammonia Refrigeration (IIAR) has released a "Carbon Dioxide Industrial Refrigeration Handbook." It is offered for purchase on the organization's website.

As noted by IIAR, due to the ban on chlorofluorocarbons and the search for replacements for synthetic refrigerants, the industrial refrigeration industry is undergoing rapid change. Renewed interest in two-stage ammonia/CO2systems prompted IIAR to compile the publication. According to the organization, tt explains the properties and advantages of CO2and covers the proper specification, design, installation and operation of safe CO2systems.
