Since the 19th Century, ammonia has displaced CO2 as the premier industrial refrigerant around the world. That looks set to change after a new survey of over 1000 individuals involved in commercial and industrial refrigeration revealed some interesting results.
An article from Cooling Post points out that 82% of OEMs and 91% of consultants surveyed saw CO2 as ‘a viable mainstream refrigeration technology’ moving onwards into and past the 2010’s.
These are encouraging signs for a technology that was once replaced by ammonia in all but a few specific industrial applications.
Although this study was conducted in the US, there’s good evidence to suggest that Europe will follow suit: European supermarkets alone installed 6000 CO2 systems in 2016.
