AIR HANDLING UNIT LIGHTING

Internal lighting of the central stations is made according to size and function of the stations.
For standard operation conditions the incandescent lamps - photo 1 - or glow-discharge
tubes - photo 2 - are used as sources of light. In those central stations, where their functioning
excludes the use (for example central stations for technological air for lacquering systems)
the above-mentioned sources of light, external sources of light are used - illustration 3. The
electrical system is placed, according to the requirements, in PVC or steel tubes. Cable routes
are usually placed outside the central station. The protection class of light sources and switches
depends on functions and requirements of the central station.
