One final obstacle that R717 systems face in South Africa today is that of perception, as ammonia-based refrigeration systems are still considered more costly than many other solutions. In a wide range of applications, it outperforms synthetic refrigerants. Japanese sake producer Takara Sake has installed an “ultra-low-charge” ammonia (R717) chiller that is 40% more efficient than a baseline R507A chiller at the same production plant in Berkeley, California (U.S.). Ammonia refrigeration systems are found in the food, beverage, petro-chemical and cold storage industries. Manfred Hofmann, expert and head of dka training at ENGIE Refrigeration, says: “NH3, or R717, is one of only a few climate-neutral refrigerants, in that it neither damages the ozone layer nor contributes to the greenhouse effect. GCAP Merchandise. R717 ammonia: The ammonia used for refrigeration systems based on the use of a compressor, condenser, expansion valve and an evaporator (Figure 11.2) is dry (anhydrous) in that there is no water in solution with it.
