ATEX Repair Guide

What is ATEX? 

ATEX stands for “ATmosphères EXplosibles,” which is a European Union directive that regulates the manufacturing, installation, and use of equipment in potentially explosive atmospheres. It aims to prevent explosions and protect workers’ safety in environments where flammable gases, vapors, mists, or dust can be present.

Why are ATEX repairs important?

ATEX repairs are crucial to maintain the integrity and safety of equipment used in potentially explosive atmospheres. Regular maintenance helps identify and address potential issues, ensuring that the equipment operates correctly and does not pose a risk of ignition or explosion.

 

ATEX repairs should be carried out by qualified engineers with specialised training and knowledge in handling equipment used in hazardous environments. They should be familiar with ATEX regulations and safety requirements. Here at CovElec, our team have been trained and assessed by the AEMT (The Association of Electrical & Mechanical Trades).

What types of EX motors are there?

There are several types of Ex (explosion-proof) motors designed for use in potentially explosive atmospheres. These motors are built to prevent the ignition of flammable gases, vapors, dust, or fibers present in the surrounding environment.

 

The most common types of Ex motors include:

 

Ex d Motors (Flameproof Motors):

  • These motors are constructed in a way that contains and withstands any internal explosion, preventing it from reaching the surrounding atmosphere.
  • The enclosure is designed to withstand the pressure generated during an internal explosion.
  • Commonly used in industries such as oil and gas, petrochemicals, and mining.

 

Ex tD Motors (Dust Ignition-Proof Motors):

  • These motors are specifically designed for use in environments where combustible dust is present, such as grain handling, flour mills, or woodworking facilities.
  • The motor housing is designed to prevent dust from entering and igniting inside the motor.

 

Ex n Motors (Non-Sparking Motors):

  • Ex n motors are designed to operate at a level below the ignition temperature of the hazardous atmosphere.
  • They are considered “non-sparking” and prevent the occurrence of sparks that could cause an explosion.
  • These motors are commonly used in chemical and pharmaceutical industries.

 

Ex e Motors (Increased Safety Motors):

  • These motors are designed to reduce the risk of sparks or hot surfaces that could ignite the surrounding atmosphere.
  • The construction includes enhanced protection measures to prevent the entry of dust, liquids, or other contaminants into the motor.
  • They are suitable for environments where the risk of an explosive atmosphere is high but not continuously present.
