Spirotrap-Improving Water System Performance (Sept. 2004)
Recently, Rogers found himself tackling a major dirt problem that was destroying the flow sensors in the campus' secondary chilled water loops. "As a result of dirt in the system, our chilled water loop was performing poorly," Rogers stated. The impellers on the vane-type flow sensors were disintegrating from the combination of the high gpm and grit-type dirt and rust that was passing through the sensors. He decided to seek the assistance of BSA LifeStructures Engineers (Indianapolis, IN) to solve his ongoing dirt problem. Once BSA confirmed the cause to be a dirt problem, they recommended a pair of Spirotrap® dirt separators with optional sediment collection tanks to clean up the system.
Rogers couldn't be happier with the units. The system is seeing improved flow and more accurate distribution of the chilled water through the secondary loop. "The units are performing very well and actually exceeding our expectation as to how much material is being removed," Rogers observed. "System operation continues to improve, and we are now seeing the added benefit of better heat transfer on the cooling coils."
