the size of the heat exchanger in this case with the slotted heat exchanger will need less heat transfer areas and direct expansion this translates into a lower the cost of the heat exchanger, however you have to put a separator on top and optimize separator Canelo has to work efficiently at the highest possible suction and reduce the ammonia charge that can end up being very close to a direct extension application separators most of you have heard about that you turn separator I'll feel about you turn is the liquid separator that comes from mounted to the heat exchanger which separates only by gravity the U-turn uses for men stop separation agglomeration surface tension Gravity Force and centrifugal force the efficiency of the operator has been a great surprise for our customers some of the advantages are small footprint compared to a traditional search from also Dramatical reduction on ammonia charge achieving 0.5 lb per ton of refrigeration can you turn also allow us to have high efficiency we estimate that the suction temperature can rice do to the optimum control of the liquid level generating annual savings between 3 and 6% unit is only available for ammonium which makes this a green solution for your application
