Application

The new telephone for use in areas with explosive atmospheres of zone 2 and 22. Its housing is made of impact- resistant and shockproof Polycarbonate and approved for Zone 2 and 22 according ATEX.

Within ranges of the chemical and petrochemical industry combustible atmospheres result again and again from process engineering operational sequence. Caused e.g. by gas, steam or nebula. Its striking signal colour ensures the FernTel 3 / Zone 2 cannot be missed whenever a telephone is urgently needed in Zone 2 and 22.

The resistance of housing and use of screws of stainles steel are especially advantageous for use in areas with high air humidity and explosive atmospheres. A deft hand movement and the desk telephone is converted into a wall telephone.
