CO2 Refrigeration Courses

There are many different types of courses in the CO2 refrigeration industry. Some job positions require vocational or technical training, some require certification, and others require on-the-job experience.  Many carbon dioxide refrigeration positions are available in the vehicle manufacturing, construction, and food packaging industries. 

Carbon dioxide refrigeration technology is a rapidly growing industry due to its huge capacity to rapidly cool using a relatively small compressor.  Unlike ammonia, CO2 is a "green" way to freeze and refrigerate because it is ozone friendly and has a low potential for global warming (GWP).  Once trained, 'job prospects are expected to be excellent' according to the occupational outlook handbook.

Students interested in this industry are urged to take classes in math, applied physics, chemistry, blueprint reading, AutoCad, and mechanical drawing.  It is helpful to gain some knowledge in plumbing and electronics in order to be a proficient CO2 refrigeration specialist.   

CO2 refrigeration is a specialized field, therefore, most technicians receive training from trade schools or community colleges.  Although there are many online courses available, employers prefer to hire individuals with at least a certificate earned from an accredited institution of higher learning that combines book learning with hands-on practice. 

A lot of carbon dioxide technicians train through an apprenticeship program offered by labor unions.   Joint committees of labor unions combine to provide three to five year programs of study allowing the apprentice hands-on training combined with classroom learning.  The three accrediting agencies that have set standards for the refrigeration industry are the National Center for Construction Education and Research, HVAC Excellence, and The Partnership for Air-Conditioning, Heating, and Refrigeration Accreditation.  A search of their websites provides information about accredited CO2 refrigeration courses.
