WHPT (FM) in Sarasota, Florida, has become the second Cox Media Group FM radio station to transition to high-efficiency liquid-cooled transmission technology from GatesAir. The installation follows one of the industry-first deployments of a GatesAir Flexiva' FLX liquid-cooled solid-state transmitter at Tampa station WSUN (FM) earlier this year.
The WHPT transmitter, which went on air in November, 2016, signifies a proactive movement within Cox Media Group to reduce its company-wide carbon footprint. The transition to more cost- and energy-efficient liquid-cooled technology for higher power FM correlates with other initiatives across the parent organization to reduce waste and electricity use.
Cox Media Group in fact partially influenced GatesAir to develop the FLX solid-state line given the success of liquid-cooling in TV transmission technology, and less successful efforts to liquid-cool FM tube transmitters due to the increasing challenges of working with tubes.
As GatesAir's latest innovation in liquid-cooling technology, the FLX uses a novel heat-to-liquid transfer process that efficiently removes heat from the RF plant, and reduces traditional air conditioning requirements and cooling costs. The technology not only cuts monthly utility costs and establishes a greener operation, but further slims down an already minimal footprint by integrating low-noise pump modules within the cabinet. This provides additional ROI value for broadcasters who share or lease space in RF plants. WHPT's FLX transmitter is now delivering 34 kW of FM and 1.3 kW of HD radio.
