Spirotherm Inc.-Air and Dirt Separators Purify Water Systems (Aug. 2006)
Spirovent® air/dirt separators by Spirotherm assure comfort for residents of University of Nebraska Lincoln.
DeCamp recalls that the Nebraska Union student center was having a terrible problem with dirt accumulating in the heating hot water system. This particular system switches between heating and cooling with the chilled water being supplied from the university's central utility plant. Because the system is not a permanently closed loop within the building, the center is supplied with dirty water in the cooling mode. When the system switches, the chilled water is heated and dirt would precipitate out of the water and deposit in the coils, strainers and associated piping. As a result, the facilities maintenance team was constantly flushing coils and cleaning strainers. They even had to replace a large section of pipe because it was too badly plugged to be flushed clean.
