Updates brought Intel Core i5 and i7 processors and introduced Intel's Thunderbolt. Called the "unibody" model because its case was machined from a single piece of aluminum, it had a thinner flush display, a redesigned trackpad whose entire surface consisted of a single clickable button, and a redesigned keyboard.
The unibody model debuted in October 2008 in 13- and 15-inch variants, with a 17-inch variant added in January 2009.
Later revisions added Intel Core 2 Duo processors and LED-backlit displays. The 15-inch model was introduced in January 2006 the 17-inch model in April. The aluminum MacBook Pro used the design of the PowerBook G4, but replaced the PowerPC G4 chips with Intel Core processors, added a webcam, and introduced the MagSafe power connector. It was the higher-end model of the MacBook family, sitting above the consumer-focused MacBook Air, and was sold with 13-inch to 17-inch screens. This allowed for resealing of the unit and ensured long lasting quality of the drain pan and interior casing.The Intel-based MacBook Pro is a discontinued line of Macintosh notebook computers sold by Apple Inc. A final coating of Blygold was applied to the floor walls, ceiling and drain pans using a Blygold Refamac 3509 Primer and a Refamac 3600 topcoat. The fan arrays had Tamco Series 7600 back draft dampers supplied on each fan, as well as Ebtron airflow measuring stations to accurately track the flow of air moving into the space.ĪTS also provided eight coils in the replacement paired with American Ultraviolet UVC bulbs to passively clean the coils to ensure the cleanliness of the coils themselves, the unit, and the air moving into the hospital.
Both air handlers were retrofitted with TMI Climate Solutions fan arrays totaling 16,500 CFM with a two by two fan array each, each fan controlled by an ABB variable frequency drive. Advanced Thermal Solutions recently retrofitted two air handlers at Sinai Hospital replacing critical components to ensure the quality airflow generated for critical hospital spaces.
