The NORSOK standard Ex equipment must be inspected every year, other standards, every second year. This is not required with the DNH Ex Maintenance Free (MF) loudspeaker range (see MT models below). The saving on maintenance costs alone makes them a great candidate, for either a new system or replacement option.
The MF loudspeaker is supplied with encapsulated cable (Radox or BFOU). These loudspeakers are filled with certified glue in the transformer and terminal chamber; the loudspeakers cannot be opened for inspection, removing the need and associated cost of an engineer to undertake the normal checking requirements.
