As part of a seven-year, $2.3 billion program to renovate DFW’s four original terminals that were built in 1974 when the airport opened, the first phase of the enormous project was completed in 2013. The renovations are a joint effort between the airport and Fort Worth-based American Airlines and include improvements to not only the terminal, but to the attached parking structure as well. With the third and final stage of the project completed in 2016, DFW Airport's four terminals now span a total of 1.1 million square feet.

Temtrol ITF air handlers with FANWALL™ technology were utilized as the basis of design for the project due to their energy efficient operation, reduced footprints and operational redundancy. A total of 50 air handlers were manufactured for the project ranging from 2,400 to 43,000 cfm, most of which are in the 15,000 to 30,000 cfm range.

In most instances, the units were shipped in the “rapid knockdown” format in order for the unit sections to be moved easily within the existing structure. One unit in excess of 40,000 cfm was installed through a standard three-foot doorway, a successful display of the flexibility of Temtrol ITF rapid knockdown units.
