Explosion-Proof! Are Your Applications Explosion Prone?

At STEGO, we take pride in simplifying the design of complex electronics that perform perfectly outdoors.

We often get asked how to make our applications “explosion-proof,” as our clients are looking to a) bracket the definition of explosion-proof and b) minimize the risk of using electronics in explosion-prone environments. 

There are only three key ingredients to create a fire or explosion: 

Flammable substance + an ignition source + oxygen = Fire!

What are “explosion-prone” applications?


Certain modern industrial environments pose an increased risk of fire and explosion due to the inherent presence of flammable substances such as gases, vapors, or combustible dust. Potentially hazardous environments are found in a range of industries, including:

  • Oil and gas refineries and distribution facilities,
  • Chemical processing plants,
  • Grain and agricultural handling, processing, and storage facilities,
  • Underground mines.

When deploying electronic control cabinets which must be heated, you inevitably introduce the second variable of the fire equation – an ignition source. Some of these risk factors include:

  • Electrical sparks,
  • High-temperature, 
  • ESD – Electrostatic discharge, or
  • Friction sparks.

The combination of an ignitable substance (i.e., combustible metal flake/dust) with an ignitor (i.e., an electrical spark) in the presence of oxygen creates a risky scenario. The best way to compensate for this risk?  Intentional component design.

Here’s the good news – you can leave the mitigation of such risks to us.

STEGO sought and achieved explosion-proof certifications from TÜV SÜD- the governing body that approves cabinet component manufacturers. STEGO has ATEX and IECEx approvals for our explosion-proof heaters.

Behind the curtains, we can tell you that designing solutions that meet this stringent requirement isn’t easy – but STEGO’s  German-engineered solution is certified for both ATEX and IECEx. 

Per the governing body: “Equipment certified for compliance with the essential requirements of the ATEX Directive (2014/34/EU) or the IECEx Certified Equipment Scheme provides assurances that the equipment does not introduce additional risks, or compromise other efforts to ensure safety.”

By selecting and trusting STEGO for your explosion-proof needs, you’ll get peace of mind knowing that you’re offering:

  1. Protection to both staff and equipment,
  2. Enhanced safety reputation for your company,
  3. Safety regulation compliance,
  4. Workplace success.

Each of us likely purchases or uses something daily that has a tie-in upstream to an explosion-risk supplier. Our commitment to our shareholders, employees, and customers is to do the work to ensure the safest possible work environment.

Trust STEGO for your explosion-proof needs.

Designing complex electronics that perform perfectly outdoors is, well, complex. At STEGO, we believe that protecting those complex projects from extreme climates should be the simplest part of your design. That’s why we use German engineering to create the highest quality thermal management components to protect your designs from anything Mother Nature throws at it. We’ve been pioneering Thermal Management for over 40 years now. With STEGO parts installed, you can rest easy that your complex design is reliably protected for the long haul.
