The International Skating Center. The Center is a world-class, twin-rink skating facility designed to meet the needs of first-time competitors and Olympic Champions alike. Olympic Gold Medalists Katia Gordeeva (shown on left) and Viktor Petrenko now headline a growing list of international skating champions who train there. As part of an environmental awareness objective and desire to support chemical-free operations, the International Skating Center installed a 6-inch Dolphin System (Pulsed Power System, or PPS) with a 3/4-inch make-up unit into its compressor system in November 2000. The following graph shows a pattern of change in microbial counts (CFU/ml) after Dolphin installation. The plot presents Heterotrophic Plate Counts (HPC) using Standard Method of Analysis (SMA) data from the end of the period of chemical treatment through the transition to Dolphin treatment. Biological counts dropped significantly. Energy and water savings achieved payback.
Managing limited funds is always a critical aspect of skating rinks in general, so the
Dolphin's superior performance and environmental criteria also had to be answerable to
cost-justification criteria. With the facility's electric bill running in the five-figure
range every month, the energy efficiency of the Dolphin was another critical aspect in its
selection. Along with other environmentally sustainable components to the facility, the
Dolphin contributes to abiding by very strict indoor-air quality standards for skating rinks,
providing a clean and healthy environment for all who use and enjoy the facility.
