Coolant for refrigerating stations

Dimethyl ether mixed with ammonia (mass ratio 40%/60%) can be used in freezing equipment. Coolant is designated as R723.

Application of this mixture as a coolant increases cooling capacity of refrigerating station. Limited solubility of mineral oil in R723 and possibility of working with copper (corrosion mitigation) allow to create a small-capacity station more effective than those with currently existing coolants.

With replacing 40% ammonia by DME in the existing refrigerating stations it is possible to obtain reduction of ammonia consumption by the station without loss of efficiency.
