Communication devices for uses in firedamp-endangered industrial areas must be particularly adjusted to their extreme operating conditions. 

Our ex telephone has been specially designed for applications in the petrochemical industry, as well as offshore installations, mills and port facilities. 

It is resistant to high temperature differences, humidity, sea water, dust and extensive mechanical strain. The ExResistTel is certified for areas susceptible to explosive dusts and gases. It is equipped with a 21-key V4A stainless steel keypad that has been especially designed for use with gloves. 

The ExResistTel is now certified to DNV GL Marine and offshore standards. Its alphanumeric display allows for a clear reading. Moreover, the telephone offers all the amenities that are already supplied as standard in the office communication sector. 

A number of accessories and components especially certified for potentially explosive areas even enhance the telephone’s functionality.
