Design and Engineering


Your project requires a personalized study and tailor-made ATEX products to meet the requirements of your installation. Our team supports you.

Dedicated lighting design

Let us draw up the diagram of your light installation.

Site design

A 3D design plan is used to provide you with a visual representation of what the final installed lighting solution actually looks like, showing the lux levels and light distribution that will be achieved on stage.

A2S can produce video designs of your final lighting system. This 3D tour offers real insight into the performance of the installation, from all angles.


We offer 2D / 3D plans to map the intensity and distribution of light points on the site. This is to show that the area is evenly lit, which is essential to achieve the highest level of safety and security.

Custom-built enclosures

In addition to standard products, A2S offers tailor-made products to meet any specific request concerning:

  • junction boxes
  • distribution boards
  • motor starter boxes
  • the command posts
  • the boxes taken, etc …

Distribution panels for lighting or heat tracing circuits, as well as small power motor starters can be made of reinforced polyester thanks to the use of Ex d encapsulated components (circuit breakers, contactors, etc.).

This innovative technology allows quick and easy access to circuit breakers located under windows that can be opened under voltage in the hazardous area (in zone 1 or 2).

For higher powers, metal boxes of different sizes are available and allow complete sets mounted on a frame.

These switchboards and boxes are always delivered fully equipped and wired to terminals, ready to be connected. We have a very wide range with rectangular enclosures for gas group IIB, or enclosures with round screw-on covers for gas group IIC.

The user thus benefits from a guarantee of full compliance with current standards and above all an optimum level of safety for protection against explosions.


Discover all our wireless solutions dedicated to optimizing industrial production processes, site surveillance and the protection of people and property. Our solutions offer a wide variety of solutions to operators for their applications in ATEX zones.
