We have 3 Frick 700 HP compressors (R717). Recently we did some maintenance on the fanbanks and found that some of the valves were not functioning properly. How often should valves used in an Ammonia System be rebuilt? These compressors service 7 fanbanks in 2 large warehouse cooler areas (38 oF) and 6 fanbanks in a large warehouse freezer (-15 oF). We noticed during a hot gas defrost in the freezer that one fanbank was heating up two other fanbanks.
The valves were installed without limit switches and there is not enough room for flow transducers (delta P), has anyone had experience with the new doppler sensors?
Thanks,
Amber
