Clearing the Air

Solving chronic air problems in residence hall

Spirotherm, Inc. The Gorham campus of the University of Southern Maine is one of three campuses that comprise USM, with a enrollment of about 9,300 students. Winters can be challenging in this climate, so heating campus buildings properly is a top priority.

Few things are more frustrating than existing buildings that continue to have problems after a major project is completed. The university had its mechanical systems in Upton Hastings Hall upgraded in 2010, and as part of the heating system upgrade, the engineer called for coalescing type air/dirt combination units. One brand was chosen based on the low bid, but after the project was completed, USM was left with chronic air problems.  

In fall 2011, Dan Gearan, associate executive director for maintenance and operations, had two Spirovent air/dirt combination separators installed in an attempt to solve the chronic air problem. The Spirovent uses the patented Spirotube coalescing/barrier medium to scrub air and dirt from hot and chilled water systems with unprecedented efficiency, enabling it to break free of the flow path. The air is released through an air-release mechanism while the dirt falls to the bottom and collects in the dirt chamber, where it can be blown down through a manual or automatic blow-down valve.   

Just after installing and filling the systems, Gearan reported, “I am happy to say we have finally installed the Spirovent units in Upton Hastings Hall, and they are working great. In fact, my guys are now asking me to look at putting one in another problem building we have.” 

Spirovents are available from ¾ inches through 36 incheshandle flows up to 30,500 GPM and improve distribution efficiency in the system by eliminating air and separating dirt.
