ATEX – essential safety

Professional refrigerators are often used for storing volatile substances, creating a potential explosive atmosphere that calls for ATEX compliant equipment. ATEX is created for protection of the users. As it should be. 

 

ATEX is an important directive, which is also why we at an early stage, contributed to making the ATEX directive guideline even clearer. Based on Gram BioLine’s inquires and subject authority, the ATEX Directive 2014/34/EU commission ruled in a “borderline decision”, on how to scope ATEX when assessing refrigerators or cabinets where explosive atmospheres may occur.

 

Terminology:

• ATEX Directive 2014/34/EU - A legislative act that sets out a goal that all EU countries must achieve.

 

• ATEX 2014/34/EU Guidelines - Facilitating document to implement the directive.

 

Intended use is key

Intended use for a cabinet is basically temperature control and allow for access to items, i.e. open and close the door. The outcome of the borderline decision considers both open and closed states:

 

§ 256 in the ATEX 2014/34/EU Guidelines: “If a potentially explosive atmosphere is likely to form around the refrigerator or cabinet as a result of vapours from inside exiting and collecting around the unit when the door is opened, it would be considered to be operating in a potentially explosive atmosphere and covered by Directive 2014/34/EU, not LVD”

 

Which means: The ATEX directive applies to both the interior and the exterior of the cabinet.

 

 

“In conclusion, if there are potentially explosive atmospheres inside the cabinet interior, it will be exposed to the exterior when opening the door”

 

It is a matter of safety
Taking the ATEX directive guidelines into consideration, there are very few, if any, situations where a cabinet door would not be opened. Meaning; if you need internal ATEX compliance you also need external ATEX compliance. And there is no room for interpretation. Failing to approach the matter of internal/external ATEX compliance in a holistic way, can have the worst conceivable consequences. The ATEX Directive guidelines dictate that, if there is a potentially explosive atmosphere inside the cabinet, when opening the cabinet - the exterior also falls under the requirements dictated in the ATEX Directive.

 

Nevertheless, we see “tick-the-box” ATEX compliance and specifications on a daily basis. What is omitted in many sales and specification processes (besides the ATEX Guidelines borderline decision on the matter) is the fact that we are dealing with safety of the users and the cabinet’s surroundings. We take the matter seriously and will always air on the side of caution, not compromising on how to interpret the ATEX Directive 2014/34/EU.

 

Certified ATEX compliance – don’t just take our word for it
Gram BioLine is today the only serial manufacturer that delivers both internal and external ATEX compliance – and at no extra cost. And you should not just take our word for it, which is why Gram BioLine cabinets are certified by third party notified bodies (TÜV Nord and DTI), taking any leaps of faith out of the equation.

Internal & external – more info

Internal ATEX
The storage space within the cabinet complies with EN/IEC 60079-15 Category 3, Zone 2 requirements. This means the cabinet can be used for storing substances categorised as potentially explosive or with a risk of creating an explosive atmosphere.

 

External ATEX
All components that are in contact with the surrounding atmosphere comply with EN/IEC 60079-15 Category 3 Zone, 2 requirements. This means the cabinet can be placed in any working area categorised as an explosive atmosphere Category 3 Zone 2 according to EN/IEC 60079-10.
