ATEX

ATEX는 매우 중요한 안전 인증 지침입니다. 프랑스어 용어 “ATmosphères EXplosibles”에서 유래되었으며, 폭발 가능성이 있는 환경에서 사용하도록 고안된 장비 및 보호 시스템을 규율하는 유럽 연합 지침을 의미합니다.

표준 산업용 브레이크는 작동 중 다음 메커니즘을 통해 점화원이 될 수 있습니다:

Electrical sparks: Electrical sparks may be generated at the terminals of electromagnetic coils, switches, or internal circuits.
Mechanical sparks: Friction or impact between moving components may generate sparks.
High-temperature surfaces: Prolonged braking or high-frequency operation can elevate the brake’s surface temperature, potentially exceeding the auto-ignition point of surrounding explosive gases or dust.
Therefore, in hazardous areas containing flammable gases, vapors, mists, or combustible dust—such as chemical plants, oil rigs, mines, paint shops, and flour mills—ATEX-certified explosion-proof brakes must be used.

ATEX 인증 브레이크는 점화원이 될 수 없도록 특별히 설계되고 엄격하게 테스트됩니다. 주요 특징은 다음과 같습니다:

Flameproof Enclosure (‘Ex d’): Electrical components capable of generating sparks (e.g., electromagnetic coils) are fully sealed within a robust enclosure. Even if an internal explosion occurs, the enclosure withstands pressure and prevents flame propagation to the external environment.
Temperature Class Control (‘T’ rating): The brake’s design and material selection ensure that even under worst-case operating conditions, its maximum surface temperature remains well below its certified T-class rating (e.g., T4 rating requires maximum surface temperature not exceeding 135°C), thereby preventing ignition of surrounding materials.
Dust Ignition Protection (Protection by Enclosure, ‘Ex t’): For dusty environments, the enclosure features a high degree of dust sealing (IP rating) to prevent combustible dust from entering the interior, while also controlling surface temperatures.
