McQuay HVAC Is Used by Entercom KC

Rooftop systems are used to reduce vibration and radiated sound

Entercom Communications is using McQuay International rooftop HVAC systems as part of a renovation at its eight-station cluster in Kansas City.

The broadcaster completed a $12 million renovation of the 60,000-square-foot building in 2006. W.L. Cassell was the engineering firm that did the mechanical renovation; McQuay said the acoustical requirement was between NC 20 and NC 25, suitable for concert and recital halls and broadcast and recording studios.

The roof was chosen as an HVAC site because of space limitations.

Two McQuay rooftop units were selected to serve the cooling load of up to 175 tons for the top two floors. Both are controlled by MicroTech II controls and are integrated into an Andover building automation system. Variable air volume boxes with hot-water boilers provide zone control and heat the building. First-floor spaces are served by a McQuay Vision air handling unit, an exterior 60-ton condensing unit and two 50-ton rooftop units.

Thermal Components, an HVAC supplier in Kansas City, also was involved in the project.
