For a product, or electrical equipment to be classified as &#;Explosion Proof&#;, it means that the enclosure of the product must be able to internally withstand:
This also means that we should not make the mistake that Explosion Proof Electrical Products are able to withstand any external explosion(s) that happens outside of the enclosure, rather it is the ability of the enclosure to prevent any internal explosion or sparks from escaping into the external environment and being the cause of a larger explosion. The term &#;explosion proof&#; is also interchangeable with &#;flameproof&#;.
Normally, explosion proof products are used in hazardous locations to reduce risk and increase safety of workplace operations. You can find out more regarding the different hazardous locations here.
Therefore, using Explosion Proof Electrical products would benefit you in the following ways:
No employee would want to work in an unsafe environment or expose themselves to unnecessary risk in hazardous environments. This would allow your employee to focus on his/her job and boost productivity and morale. Your employees would be at ease knowing they are working at an organization that values their safety by using explosion proof products.
Your organization&#;s reputation is definitely an important factor and using explosion proof products would help in that aspect by minimizing any external explosions and mishaps. This would ensure a clean safety record and encourage other organizations to work with yours. Future employees might also research on your company before deciding to join so it would be beneficial to have a good safety record.
By using certified explosion proof products, you would minimize damage to your facility by containing any explosion to within the enclosure itself and not to the surrounding areas. Another important fact is any reduced external explosion would minimize any risk to your staff and reduce greatly the chance for cost relating to medical claims or staff suing your company for any workplace mishaps.
There are 2 main certification bodies that certify explosive proof equipment:
You can find out more about the above 2 independent certifications here. These 2 certifications are acceptable throughout most parts of the world, although North America uses the NEMA standard, while Russia uses the EAC Ex standard.
Our design engineers use AutoCAD software which is the industry standard to prepare detailed custom drawings based on your specifications. This also leads to quick turnaround time in making any revisions to the drawings. We would also provide expert advice on the different ways you can customize and configure the various explosion proof products that we carry to your needs. Once the drawings are approved, next would be the production/testing phase.
We maintain the strictest standards during the production phase for our explosion proof electrical equipment.
The first step is the casting process where your order gets meticulously casted in our dedicated factory by our specialists in Europe.
When the enclosure is ready, we configure it based on your requirements and confirmed drawings, including drilling of entries and integrating electrical components. This is all done at our certified workshops located in Singapore, UAE, and Slovenia.
Next, once the final product is ready, it will go through testing by our experienced QA/QC engineers to ensure it meets all the product certifications and required standards before it is ready to be delivered and installed.
If there are any issues, rest assured our skilled and friendly colleagues will be on hand to provide any troubleshooting and maintenance services that are required. We also offer services ranging from spare parts replacement, ad-hoc corrective repairs, to regular checks and scheduled preventive maintenance.
Our range of Explosion Proof Electrical Equipment and ATEX products are manufactured with the latest available technologies, both mechanical and electrical, using materials that guarantee the best protection against corrosive agents as well as to provide you with modern functionality and long durability concurrently.

The IECEx Scheme provides a means for manufacturers to obtain Certificates of Conformity that will be accepted at national level in all participating countries. A Certificate of Conformity may be obtained from any certification body accepted into the scheme. The objective of the IECEx Scheme is world-wide acceptance of one standard, one certificate, and one mark.
IECEx is a certification scheme championed by the IEC (www.iec.com) , and it is fast becoming the preferred route for international safe certification of products for use within all hazardous areas.
The IEC test report provides detail not included within an ATEX certificate and can be locally ratified to overcome any destination market legislative difficulties that may arise.
In contrast to ATEX, IECEx was designed from the outset as an ISO/IEC Type 5 Certification Scheme, employing a single third party (The IECEx Certification Body) to combine all aspects of design evaluation and production control before issuing a certificate.
ATEX is a mandatory legal requirement within Europe. Therefore the IECEx certification is complimentary to the ATEX standard, making the choosing of equipment that has compliance to both standards advantageous if the final destination is outside the EU.
IECEx and ATEX marking differs and dual marking is becoming increasingly common. Dual marking enables products to gain an equal acceptance status in the countries signed up to the IECEx scheme as they currently receive in Europe.
The IECEx scheme is a very positive step towards a world certification system.
However, while total global harmonisation is still some way off, more and more countries are adopting this international certification scheme.
Many manufacturers have acknowledged this shift and have begun adding IECEx compliance to their list of approvals.
From onwards, the IEC Technical Standards in the series IEC , and in particular IEC Part 14, have recognised that there may be occasions where it is necessary to increase, above the normal levels, the protection against ignition sources. This concept allows for consideration of risk (ie consequences of an explosion) as opposed to just the probability of a flammable atmosphere existing &#; the conventional selection criteria between the types of protection and the zone of use.
In normal circumstances the effect of these EPLs will be to retain the normal zone/equipment protection relationship. If, however, the risk is considered especially severe, then the required EPL for the zone may be increased. Similarly, if the risk is deemed to be especially small or negligible, the EPL may be reduced from the norm.
The following two tables show the normal relationship between EPL and zone, and the EPL awarded to each type of protection

Note that the series of standards will gradually address dust hazards as well as gas/vapour hazards. The standard number will have an additional suffix 1 or 2. Thus, for example, -14 (see below) will be replaced by -14-2 [installation for equipment in dust hazards], with -14-1 dealing with installations in gas/vapour hazards.
