Custom fabricated 24" high velocity combination air eliminator / dirt separator for the hot water system and custom fabricated 30" high velocity air / dirt for chilled water.
Install the Spirovent® at the point of lowest solubility, which is the place in the system where the temperature is the highest and pressure the lowest.
After having tried numerous other methods, the first Spirovent was installed in Carman Hall to deal with a long history of no heat calls and clogging valves.
