Liquid-cooled high-power transmitters for digital TV
Features
Cooling system
The standard cooling system (as an external unit outside the transmitter rack) consists of one pump unit per transmitter rack. The pump unit contains two series-connected pumps and a control unit ensuring full redundancy. A heat exchanger for each pump unit is installed outside the transmitter room. For redundancy reasons, the heat exchanger is fitted with two fans in active standby. AntifrogenN is used as the cooling agent. To save energy, the motor speed of the pumps and the fans on the heat exchanger is regulated by the control unit depending on the outside temperature.
