Installing gages at the end of the longest circuit to read the differential pressure, throttling the pump until the specified valve drop was indicated on the gages, and reading differential at the pump, will yield the true piping loss. With few exceptions, the piping loss was far less than expected.
This can result in significantly different network piping losses from one terminal unit to another, requiring some type of correction (e.g., balance valves, active flow-limiting devices, or perhaps pressure-independent control valves) to keep the system balanced and piping losses equal.
The performance of D-R's ICS, incorporating DATUM compressor and rotary separation technologies, will be competitive to the overall performance of traditional systems when the suction scrubber and inlet piping losses are taken into account.
