Liquid Cooling Effectively Chills Transmitters
The cooling system in broadcasting transmitters is a key factor in determining the efficiency of the entire system; the necessary coolant flow is calculated based on number of amplifiers and system set-up. The recently-developed technology of liquid cooling not only contributes to an effectively chilled system, but also extends transmitter lifetime and provides energy savings. Since the water is in close proximity to the electronic system, it’s vital to ensure no leakage occurs. With our no-spill quick connect couplings, we can make sure systems are kept temperature controlled and dry.
