Product Description

Product Description

Main Features

The Explosion Proof Telephone is designed for voice communication in the hostile environment where reliability, efficiency and safety are of prime importance. The telephone can handle the large temperature differences found outdoors, high humidity, exposure to sea water and dust, corrosive atmosphere, explosive gases & particles, as well as mechanical wear and tear, making it perfect for use as an emergency telephone.

Ideal for chemical plant, oil&gas, onshore and offshore drilling platform, oil refinery, mining, power stations and heavy industry which require very reliable and explosion protection telephony under adverse conditions.

•  Hotline telephone without keypad, programmable for auto-dial
•  Handset with noise-cancelling microphone and 80 cm armored cord (optional heavy duty curly cord)
•  The handset supports hearing aid compatibility (HAC)
•  Orange color (other colour on demand)
•  Without door cover, supports wall mounting with mounting bar
