Ex enclosures made of aluminium, polyester and stainless steel as well as control stations and other Ex equipment offer reliable basic protection for electrical distributions used in potentially explosive areas. The application range of the products is categorised in zone 1 and 2 for gas explosion protection, and in zone 21 and 22 for dust explosion protection. For different applications, different protection concepts will be available:
● Ex eb increased safety
● Ex ia intrinsically safety
● Ex db flameproof encapsulation
● Ex tb protection by enclosure.
These Ex stainless-steel flameproof enclosures are of high quality and designed to conform to IEC and ATEX standard.They deliver peak performance even in harsh and aggressive environments, such as:
● Locations near seawater
● Areas that demand the highest level of cleanliness and purity
● Chemical and petrochemical industry
● Process industry
● Lacquer-processing industry
● Mining Silo installation
They are also helpful in all EMC applications.
We manufacture our ATEX stainless steel enclosure from AISI 316l stainless steel with complete stainless steel fixings.

Using Stainless Steel Explosion Proof Enclosures – What You Must Focus On
While using ATEX Enclosures for various applications in a high-risk and explosive atmosphere, the operator must take extreme precautions on several fronts.
You may run an appropriate test, but that is not enough.. You must be well conversant with the operational part of the device and its various functions.
Operators must make sure that their maintenance team is competent and experienced to achieve and maintain pressure-tight encapsulated enclosures. This will ensure that the enclosure system runs smoothly and does not pose any kind of operational risks.
More Reasons For Using Our Explosion Protected SS Enclosure
The key reason for using the best stainless steel explosion protected enclosure is to contain an internal explosion and prevent it from spreading. We also designed the ATEX enclosure to protect the equipment fitted from impurities and adverse elements, such as dirt, dust, and moisture.
Our superior stainless steel flameproof enclosure withstands all types of internal explosion. The ignition gap comes with a unique design. It helps avert hazardous elements such as hot gases, flames, and sparks from scattering. It offers solid protection from any potential environmental damage.
