What is an Ex d Enclosure?

Ex d Enclosures are designed to withstand and contain internal explosions without allowing the flame or explosion to escape the enclosure and ignite the surrounding explosive atmosphere. This makes them ideal for use in hazardous locations where explosive gases, vapours, or dust exist.

The construction of Ex d Enclosures is robust, providing a method of protection in explosive atmospheres by containing any explosion within the enclosure itself. These enclosures are meticulously engineered to prevent the transfer of sufficient energy to the explosive environment, ensuring the safety of the operation and personnel.

Certified to meet international safety standards, (IECEX & ATEX) Ex d Enclosures are a critical component in the oil and gas, chemical, and pharmaceutical industries, among others. Their application is crucial in environments where safety cannot be compromised, offering reassurance that operations can proceed without the risk of igniting an explosive atmosphere.

Quality Assurance

We have a structured Quality Assurance (QA) system, that allows us to pay more attention than is required.

Depending on how critical the shipment is, we assign a QA level that determines whether the product is checked by one person, two people, or the engineering team – so the QA is always tailored to suit.

Our process involves two different check levels that ensure;

  • Overall compliance
  • The product is fit for purpose
