| Simple Payback (years) | 1.89 | 2.54 | 2.36 |
| Quiet The Daikin McQuay Magnitude™ chiller is the quietest chiller in its size range with sound pressure ratings as low as 76 dBA per ARI Standard 575. That makes it ideal for sound sensitive environments such as schools, performance halls, museums, condominiums and libraries. |  |  |
| Ideal for Retrofit and Replacement The compact size of the Magnitude™ chiller makes it ideal for retrofit and replacement installations. In addition, the space that would have used for equipment can now be put to more productive use in the facility. |
| Reliable From 2003 through 2009, nearly one thousand Magnitude™ chillers have been installed around the world, providing consistent comfort and energy savings. | |
