Heat Dissipation 3.6.1
The FA Series is provided with a highly efficient LED chip to reach low power consumption, less
heat production and a long working life.
The modules are designed fan-free which ensures a super quiet operation. The whole housing of
the module is designed as heat sink.
Cooling 3.6.2
The required ventilation depends on each particular project. Depending on the structural design
and environmental temperature it may be necessary to add an external cooling.
To integrate the ideal, energy-efficient air conditioner for the LED display, you have to determine
the capacity or size you need. This is important for two reasons: An undersized unit will not cool
adequately the LED display in extremely hot weather. An oversized air conditioner can also
adversely affect your comfort. The unit may switch on and off too often, without running long
enough to dehumidify the LED display properly or cool the space uniformly. And it will consume
more energy than necessary.
Info
The ideal environment temperature for the LED display is 10 – 25 °C.
