Merging the performance and reliability of its Flexiva air-cooled platform with the high-efficiency, liquid-cooled technology of its Maxiva TV and DAB radio transmitters, GatesAir is debuting the Flexiva FLX range of liquid-cooled transmitters for stations and networks operating between 5kW and 80kW.
The new range is engineered to remove heat from the RF plant in the most efficient possible manner, according to GatesAir.
The design incorporates a heat-to-liquid transfer that is considerably more efficient than air-cooled processes, especially at higher power levels. The process moves transmitter heat to the outside via a liquid-to-air heat exchanger with redundant fan systems.
Redundancy is a key design benefit across the entire liquid-cooled architecture. To obtain maximum efficiency, the system, in most installations, integrates low-noise pump modules within the transmitter to further reduce its already compact footprint.
Two fully redundant cooling pumps operate in a closed-loop design, with auto-changeover capability in the event of a module failure to ensure proper and constant transmitter cooling. The pump and heat exchanger motors are speed-controlled to lower operating costs and provide optimum cooling performance over an array of weather conditions.
The liquid-cooled design is among the attributes of GatesAir’s PowerSmart 3D architecture, which the company claimed reduces carbon footprint and operating costs by as much as 50 percent overall.
When combined with PowerSmart 3D’s broadband amplification to enhance power density, broadcasters see the additional benefits of reduced transmitter footprints, weights and rack space requirements, said GatesAir.
