Ex-proof Gas Detection Systems CT-THEME

All electrical devices used in environments where explosive and flammable gases or substances that form such gases are used are required to have flame-proof properties and Atex certification.

All types of gas detection and warning devices used in such environments must be able to work isolated from the environment.

For an ex-proof gas detection system, it is not enough for the products to be certified. All infrastructure cabling, piping and assembly equipment must have the same characteristics.

System equipment: Ex-proof gas detectors, Ex-proof flashing lights, Ex-proof sirens, Ex-proof warning buttons, Ex-proof pipes, ex-proof(Does not spread flame)

Ex-proof warning devices are in the form of Ex-proof sirens, Ex-proof flashing flashers, Ex-proof sirens with flashing lights, Ex-proof warning buttons.

Ex-proof (flame retardant) infrastructure and connection equipment: In order for the installed system to be Ex-proof (flame retardant), all infrastructure and connection products must have the same features. Ex-proof pipes, ex-proof (flame retardant) fittings, glands, ex-proof junction boxes are the products generally used in these applications.

Ex-proof ventilation fans and smoke dampers:

In facilities where explosive and flammable materials are located, Ex-proof ventilation fans must be used to evacuate the air or provide fresh air to the environment. There are also portable ones for temporary work.

Classification of Places Where Explosive Atmosphere May Occur:

Dangerous places are classified into regions based on the frequency of occurrence of an explosive atmosphere and the duration of this environment, taking into account the definitions below. It is important that the detection devices to be used in these places are made of the appropriate type and the infrastructure is created accordingly.

- Zone O: Places where an explosive atmosphere consisting of a mixture of flammable substances in the form of gas, vapor and mist with air occurs continuously or for a long time or frequently.

- Zone 1: Places where an explosive atmosphere consisting of a mixture of flammable substances in the form of gas, vapor and mist with air may occasionally occur under normal operating conditions.

Zone 2: Places where flammable substances in the form of gas, vapor and mist are not likely to mix with air and create an explosive atmosphere under normal operating conditions, or even if such a possibility exists, places where the explosive atmosphere is permanent for a very short time.

Zone 20: Places where flammable dust in the form of a cloud in the air may create an explosive atmosphere continuously or for long periods of time or frequently.

Zone 21: Places where flammable dust in the form of a cloud in the air may occasionally create an explosive atmosphere under normal operating conditions.

Zone 22: Places where, under normal operating conditions, there is no possibility of clouds of flammable dust in the air creating an explosive atmosphere, but even if such a possibility exists, this is only valid for a very short period of time. Places where flammable dust is present in layers or piles should also be considered as another source that may create an explosive atmosphere.
