Ammonia21 has highlighted a recent presentation given at GCCE 2017 in Chicago by Bruce Nelson, President of Colmac Coil, and Rick Watters, Vice-President of AMS Mechanical Systems. The session compared Colmac’s low charge ammonia ADX® systems versus traditional pumped liquid overfeed systems on a variety of criteria including energy consumption, safety, and overall efficiency.
After measuring data from two installs of the ADX® systems, the results were not entirely as expected. “On paper, we calculated that the [ammonia DX systems] would use 1.3% more horsepower per ton than a liquid overfeed system, but the bottom line is that the premium we thought was going to exist to do DX ammonia really doesn’t exist,” stated Watters.
