PEX6 explosion proof industrial phone


Analogue Explosion Proof Phone with amplifier and loudspeaker

PEX6 is an  explosion-proof analog phone specially designed for hazardous area communication. The explosion-proof telephone uses heavy metal as the raw material of the outer casing, and its housing is firm and vandal-proof. It can be used in emergency environments such as petrochemical mining and the like as emergency communication equipment.

PEX6 is an intrinsically safe phone, designed for use in nuclear power plants, chemical, petroleum, natural gas and other hazardous areas to provide intrinsically safe communications equipment. The phone is suitable for use in fires where the environment is filled with flammable gases, steam, dust, flammable vaporized liquids, or in an environment filled with flammable fibers in the air.

In the dangerous environments, PEX6’s normal work will not be the source of the explosion. The intrinsically safe phone PEX6 cast in a metal case, has a waterproof rating of up to IP66 and is dust and drop resistant.

PEX6 is certified by international IECEx and ATEX. The safety availability can be fully guaranteed.
