The industrial refrigeration industry sees CO₂ as a viable mainstream technology for refrigeration, according to the results of an online survey conducted by Danfoss.

The results show that OEMs and contractors are advancing the acceptance rate, with 57 percent of responding OEMs and contractors and 43 percent of consultants and end users indicating they have already either been involved in a CO₂ refrigeration project or have plans to be. OEMs and contractors identified the removal of ammonia, in terms of improved safety and reduced ammonia charge,  as a key driver in using CO₂ for industrial refrigeration. Consultants and end users agreed, but they also cited pending legislation/regulation as important factors.

Danfoss conducted the survey, which collected input from industrial and commercial refrigeration OEMs, consultants, contractors and end users, to gauge industry acceptance of CO₂ refrigeration systems in North America.
