Tele-net engineers designs and supplies various types of industrial telephones. These industrial telephones are used for both safe and non-hazardous areas of the plant. Some of the constructional features of these phones include: robust material of construction aluminium, tone dialing line powered, noise-canceling microphone, external fibre canopy, built-in ringer, highly reliable, efficient operation, low-cost and good clarity in speech. Where use of normal telephones is prohibited, these telephones are required either due to safety regulations or due to environmental conditions or due to high ambient noise. There are two different models of these industrial telephones which include: flameproof telephones and weatherproof telephones. Flameproof phones are intrinsically safe and are suitable for all hazardous areas of gas groups i, iia, iib and iic. Weatherproof phones are ip-66 protected and are suitable for all non-hazardous areas.
