Flake ice production with natural refrigerants? - Yes, we can!
Environmentally friendly and extremely efficient, MAJA offers flake ice machines for direct operation using the natural refrigerants ammonia (R 717) and carbon dioxide (R 744) – an interesting technology for all those valueing on ecological impact and sustainability.
There is an ever-increasing need in all of the food distribution sectors for refrigeration solutions that employ “green” technology to fulfill the requirements to produce low temperature environments. That’s why a manufacturer of refrigeration equipment will sooner or later be faced with the question of ecology, especially as the legislation will remit important restrictions in this field.
The German machine manufacturer MAJA has taken the necessary steps towards a “green future” by developing flake ice machines working with the natural refrigerants R 744 CO2 and R 717 NH3.
The refrigerants carbon dioxide and ammonia consist from the elements oxygen, hydrogen, nitrogen and carbon. They count among the gas mixtures which are natural parts of the earth atmosphere. They have almost no influence on the destruction of the ozone layer and the greenhouse effect, which is the case for the current CFC-containing refrigerants.
Especially supermarkets count more and more on R 744-technology: MAJA has been active in CO2 refrigeration for about three years with high interest from all major supermarket chains, especially in France and other retailers in Germany, Switzerland and the rest of Europe. In France for example, nearly all big supermarket chains have a MAJA CO2 flake ice machine running in at least some of their stores, and the demand is increasing constantly.
The MAJA-range includes a special line for direct CO2 operation with capacities between 500 - 4000 kg / 24 h. The CO2 operation is designed for connection to a subcritical CO2-circuit for highest efficiency, offering up to 30% more capacity compared to the refrigerant R404a.
