Natatorium Dehumidification Units Improve IAQ, Boost Energy Efficiency
Constructed in 1968, the Burdick Hall natatorium on the campus of Towson University in Towson, Md., lacked air conditioning, which resulted in a significant lack of temperature and humidity control. Furthermore, the ventilation equipment was in poor operating condition and well past its economic life....
Cooling-Tower Design for Critical Applications
Several factors need to be addressed prior to determining the appropriate cooling-tower system for a facility with critical demands. Locations, such as data centers, medical centers, airports, and electronic-chip manufacturers, require special considerations in addition to the requirements of an average cooling-tower system....

Gas-to-Steam Humidifier Helps Museum Preserve Artifacts, Reduce Energy Costs
Dedicated to the memory of Glenn H. Curtiss, who in 1908 manned the first pre-announced public flight in America, the Glenn H. Curtiss Museum in Hammondsport, N.Y., is filled with hundreds of historical artifacts. Made of a variety of materials (wood, canvas, fabric, paint), those artifacts are subject to cracking, chipping, peeling, and distortion without the right amount of humidity—ideally, 40- to 60-percent relative humidity (RH). The museum, however, lacked a humidification system, and RH hovered between 3 and 10 percent....
Temporary Dehumidification Protects High-End Millwork in New Ballpark
Located in the historic Warehouse District of downtown Minneapolis, Target Field, the new 40,000-seat, open-air ballpark Major League Baseball’s Minnesota Twins call home, includes themed restaurants, state-of-the-art locker rooms, and 54 private suites. The ornate millwork, cabinetry, and high-end finishes in these and other indoor areas required special care during the facility’s construction in 2009. ...
