ADOTT Solutions is an engineering service company, focusing on electronic product development (PCB, Embedded Software, Industrial and Mechanical Design). We provide services from product ideas through development, validations and certifications until implementation into volume production. Our engineers are highly experienced in designing complex high-speed circuits and industrial products.
We are proud to have successfully certified a number of complex and energy-demanding Intrinsically Safe products for all zones of explosive atmospheres.
We are honoured to have satisfied clients from all over the world.Our team
Our mission is to research and formalize techniques, design and design-review procedures that increase the
At some workplaces explosive gases, vapors or dust/fibers may be present in the atmosphere (collectively refereed to as Explosive Atmospheres). Typical examples would be in the oil and gas industry, mines, chemical and pharmaceutical industry, mills, etc.
Combustion is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant (usually atmospheric oxygen), that produces oxidized, often gaseous products, in a mixture termed as smoke. Explosion can be looked at as a very rapid combustion, in which differences in pressure and/or temperature propagate rapidly. Supersonic explosions are called detonations.
Eliminate the presence of at least on of the following:
Different techniques to achieve the above targets are outlined in standards. One of the most widely recognized standard is the series of IEC 60079. Many localized standards are also derived from this international standard series, like for North America and Europe (ATEX Directive).
Eliminating the Presence of Flammable or Combustible Materials
…is by definition impossible, as we have have defined Hazardous Locations as places where these materials may be present in the atmosphere 😉
However industry standards are classifying these places into ZONES (IEC 60079-10) or DIVISIONS (NEC, NFPA 70 and CSA C22.1) based on the probability of occurrence of explosive atmospheres:
In North America DIVISION 1 used to cover ZONE 0 and ZONE 1, while DIVISION 2 is analogous to ZONE 2.
Eliminating the Presence of Oxygen and/or Explosive Gases
IEC 60079 series outline the techniques to eliminate Oxygen or explosive gases from the equipment where ignition sources may be present. Just a few examples:
Eliminating the Presence of Ignition Sources
IEC 60079 series gives several possibilities for eliminating ignition sources from equipment. One of the most suitable for mobile equipment and the one that is applicable to all Zones is
ADOTT Solutions specializes in equipment development that is compliant with IEC 60079-11. We have developed a patent pending solution for current and voltage limiting on intrinsically safe PCB-s. This allows high performing lightweight mobile electronic devices to be certified for use in hazardous areas, which was not possible before.
We are also pioneering in developing and certifying high capacity rechargeable batteries that are certified for use in Zone0, Zone 1 and Zone 2 in explosive atmospheres, according to European ATEX directive and based on IEC 60079-11 standard. We use cells that can be even punctured or mechanically damaged, and will still not get into the runaway state to catch fire or explode.
