Two 280-ton Daikin Magnitude chillers also are helping to reduce operating costs of the Hotel Nikko San Francisco, a 25-story, 533-room, Four Diamond Award®-rated hotel near Union Square. In addition to replacing the building's aging and unreliable chillers, Hotel Nikko also wanted to find a way to reduce its carbon footprint. It chose Daikin Magnitude chillers for their ultra-quiet operation, use of R-134a refrigerant, and reduced maintenance needs. As a result, the new Magnitude chillers provided annual energy cost savings of 15.2 percent, and helped Hotel Nikko become a seven-time recipient of the U.S. Environmental Protection Agency's (EPA's) Energy Star® award as well as obtain a rebate from the local utility for 5 percent of the total installation cost.
