GatesAir Brings High-Efficiency Liquid-Cooled Transmitters to IBC 2015
New technology advances in liquid cooling for solid-state transmitters at medium-to-high power levels reduce the total cost of ownership, enabling broadcasters to transition from high-maintenance models
Cincinnati, OH, August 13, 2015
GatesAir, a global leader in wireless, over-the-air content delivery solutions for radio and TV broadcasters, will demonstrate the latest advances to its solid-state Flexiva™ radio and Maxiva™ TV and DAB Radio transmitters at IBC 2015—including the international debut of the Flexiva FLX range of liquid-cooled transmitters for FM and digital radio broadcasters (HD Radio™, DRM+).
Building on the foundation of the award-winning Flexiva FM air-cooled platform and leveraging advances first instituted in medium-to-high power Maxiva transmitters, the Flexiva FLX design incorporates a heat-to-liquid transfer that removes heat from the RF plant without excessive air conditioning, helping broadcasters cut monthly utility costs and establish a greener plant. The transfer itself cools the air in the RF plant, moving transmitter heat to the outside via a liquid-to-air heat exchanger with redundant fan systems.
In addition to low total cost of ownership over the long term, GatesAir’s high-efficiency PowerSmart® 3D transmitter architecture slims down the overall size and weight through a significant reduction in the number of internal modules and power supplies. This exceptionally high power density significantly lowers operating costs for higher power, solid-state transmitters thanks to a much more energy efficient and compact design. Notably, the significantly fewer number of internal parts to manage also equates to minimal, single-engineer maintenance—a valuable benefit compared to tube transmitters.
“Our continued efficiency increases in solid-state liquid-cooling technology makes operations far more cost-effective, and simpler to maintain than in the past,” said Rich Redmond, chief product officer, GatesAir. “Add in a quickly changing broadcast engineering workforce and dwindling availability of tube transmitter parts, and the value proposition for solid-state quickly becomes clear. As a result, we see as many broadcasters transitioning to solid-state transmitters for both maintenance and power efficiencies.”
To obtain maximum efficiency, the liquid-cooled design, 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 failure to ensure proper and constant transmitter cooling. The associated size and weight improvements are especially helpful for broadcasters who lease space in the RF plant by the square foot. For example, Flexiva provides a foot print reduction of over 50%—a remarkable difference in monthly rental costs.
GatesAir will demonstrate 10kW Flexiva FLX and Maxiva ULXT transmitters on the exhibit floor at IBC 2015 (September 11-15, RAI Convention Center, Amsterdam, Stand 8.B20), additionally demonstrating the high-efficiency broadband amplification of Maxiva transmitters for TV and DAB Radio broadcasters. Broadband amplification, a core benefit of the PowerSmart 3D design, ensures that broadcasters can streamline frequency and modulation changes through a single-amplifier design. This simplifies changing to new channel assignments, for example, by eliminating labor-intensive component and sub-assembly changes; and reduces spare parts to a common set that can be shared across large transmitter networks for additional value.
