Cox Media Group goes green with GatesAir

GatesAir’s Flexiva FLX liquid-cooled transmitters are now installed at two of Cox Media Group’s radio stations

As part of Cox Media Group’s initiative to reduce carbon footprint, its WHPT-FM radio station in Sarasota, Florida, has installed GatesAir’s Flexiva FLX liquid-cooled transmitter. The transmitter, which went on air last November, is now delivering 34kW of FM and 1.3kW of HD radio.

This decision was made following a successful deployment of the similar transmitter for WSUN-FM, another Cox Media Group radio station, in Tampa, Florida.

Using a novel heat-to-liquid transfer process to remove heat from the radio frequency (RF) plant, the deployment of FLX transmitter is able to reduce traditional air-conditioning requirements, according to GatesAir, thereby reducing utility costs while establishing a greener operation.

Roz Clark, senior director of engineering, radio, Cox Media Group, concluded: “We see a strong potential for return-on-investment (ROI) when it comes to liquid-cooled technology in FM radio. The capital and operational investments as well as electrical costs associated with moving heat around are reduced, as liquid can cool transistors far more effectively with air.”
