Old Breweries Are Brought Up to Date with a Not So New Refrigerant
“Nowadays, these systems are not just energy-efficient. If they also use natural refrigerants like ammonia [NH3], they are also particularly environmentally friendly,” said Georges Hoeterickx, member of the board of Eurammon, the European Initiative for Natural Refrigerants. “This is because natural refrigerants have no, or only very low, global warming potential.”
It is an accepted fact that brewers had a major influence in regards to the development of refrigeration systems. In 1876, an ammonia system enabled a Bavarian brewery to produce beer at any time of year. Over the years, there have been significant developments, of which a number are noted here.
