Penn State University and the Central Pennsylvania community unveil one of the nation's premier facilities in Pegula Ice Arena
Pegula Ice Arena, located at the University Park campus of Penn State University, has quickly become recognized as one of the premier ice arenas in North America. This state-of-the-art facility was made possible through the generosity of alumnus Terry Pegula, and his wife, Kim, who contributed $88 million toward the construction of the arena. This monumental gift was the largest philanthropic donation in Penn State's storied history.

Comparison of Glycol Refrigeration Dehumidification to Desiccant Dehumidification
CDI has specialized in providing desiccant dehumidifiers to ice arenas for over 25 years. The first desiccant system installed replaced a cold-coil system that was supplied with low temperature glycol from a rink chiller plant using ammonia refrigeration; a hot water coil was used to reheat the air after the dehumidification coil.

Operating Rooms - Controlling the Humidity with Desiccant-based Dehumidification
By incorporating a desiccant-based dehumidification system into the mechanical design for the hospitals operating suite, the overall system can be designed for optimal and active humidity control. No longer does the surgical staff have to tolerate less than desirable space conditions. No longer would there be a threat of it "raining" in the operating room during surgeries (i.e., condensate forming and dripping from the metal fixtures on the ceiling). More...

Meeting NHL Standards for Large Spectator Ice Arenas
The impact of water vapor on ice surfaces has been a definite target for the Recreation Arena (Less than 2500 seats). These venues have utilized desiccant dehumidification to maintain optimum humidity levels for the best ice quality while maintaining and energy effective environment. Spectator Arenas (2500 Seats or More) have generally used traditional mechanical systems that rely on refrigerant based cooling for dehumidification and reheat system for temperature control.

Energy Choices for Plastic Processing
"To prevent condensation, Graham installed enclosures around the molds to limit air intrusion, and piped desiccated air into the enclosures. The desiccated air starts ambient air pulled into a desiccant dehumidifier. One dehumidifier can serve several automated molding machines. There are a number of ways engineers reduce airs humidity. The least expensive most reliable way of producing dry air in high volume is with a desiccant dehumidifier."

Ice Arena Mold Contamination
Mold or "Toxic Mold Syndrome" is a hot topic. Cases of black mold or toxic mold are frequently reported in newspapers and industry trade journals. Since ice arenas can be ideal sources for growth of molds that are hazardous to some individuals, managers and arena operators need to know about this evolving problem. This article addresses the basics of the problem and the conditions and challenges in treating mold areas. More...

Advanced Reactive® Desiccant Dehumidifiers for Long Term Layup and Corrosion Control
Controlling corrosion in metals is best accomplished by removing atmospheric water vapor from ambient air. The goal is to condition the ambient (air) moisture vapor pressure (dew point) to always be below the dew point temperature of the metal surfaces. To prevent moisture from collecting on the metal surfaces the ambient vapor pressure must be maintained to a lower vapor pressure than that of the surfaces.

Drying Skating Equipment, Reducing Mold and Mildew in Locker Rooms.
Moisture is a fact of life in locker rooms from high school sports through major arena sporting events. The shower room, equipment and storage areas are ripe with smells and odors from showers, damp equipment and uniforms. The smells and odors are created by molds and bacteria that are thriving in the high humidity environment of the locker room. More...
