Intrinsically safe telephone for dangerous zone

Instrinsically safe telephone work as atex equipment made of GRP by die casting. The IECEx explosion proof telephone is rugged and durable. KNTECH design and manufacture the telephone with IECEX tertification and export to 50 countries. This Explosion proof Instrinsically safe telephone works in Hazardous Area. The explosion proof telephone use in zone 1 and zone 2. It can also use in Division 2.Ex II 2 GD & Ex ii 2G IECEx Certified explosion proof telephone.

KNEx1 intrinsically safe automatic telephone and anti-noise automatic telephone are high-performance and high-reliability communication terminals successfully developed by adopting modern electronic technology and fully integrated circuits. It is matched with the mine safety coupler and can be connected with various existing ground switches or dispatching mainframes to form a coal mine production scheduling communication system. The telephone can also be applied to other harsh working environments with high temperature, high noise, high temperature and heavy pollution, such as power plants, coal preparation plants, steel plants and ports.

ATEX electrical equipment explosion-proof type

1, Ex d (explosion-proof type)
2, Ex e (increased safety type)
3, Ex i (intrinsically safe)
4, Ex m (casting type)
5, Ex n (non-sparking type)
6, Ex p (aerated positive pressure type)
7, Ex o (oil immersion type)
8, Ex q (Zeng’an Zhongchong type)

Intrinsically safe: The energy of the circuit is limited by the relevant technology, so that the electrical energy generated in the electrical equipment generates sparks or hot surfaces that are not sufficient to detonate substances in the explosive environment.
Increased safety type: Through the design of the product, it can eliminate the detonation source of hot surface or electric arc or electric spark to achieve the purpose of explosion protection.
Molded type: A device or part of a device that may ignite an explosive environment is encapsulated in a substance to isolate the device or part thereof from substances in an explosive atmosphere for the purpose of explosion protection
