Boeing Longacres

Project Highlight: Boeing Longacres

MacDonald-Miller provided the following panel upgrades in response to the request from Boeing to upgrade the existing obsolete chiller panels and provide an alternate to the standard Original Equipment Manufacturer (OEM) deliverable.The upgrade allowed Boeing to receive equal performance and in some cases improvements above the factory OEM panel. When repairs occur this option can be 10 times less costly for materials and gives MacDonald-Miller the ability to monitor water GPM and most analog or digital inputs the customer would like to see on the front panel.
