What is the primary benefit of an explosion-proof freezer?

The primary benefit is the safe storage of highly flammable or explosive substances, significantly reducing the risk of ignition within the unit. This is crucial for laboratory safety and compliance.

How does static cooling differ from forced-air cooling?

Static cooling relies on natural convection to distribute cold air, leading to very stable temperatures ideal for sensitive samples. Forced-air cooling uses a fan for faster temperature recovery and more uniform distribution, but can cause more dehydration.

What certifications should I look for in an explosion-proof freezer?

Buyers should look for ATEX certification, specifically ATEX 95 (now Directive 2014/34/EU), which confirms the unit's suitability for use in potentially explosive atmospheres.

Is routine maintenance required for these freezers?

Yes, routine maintenance typically involves cleaning the condenser, checking door seals, and ensuring the alarm systems are functional. This helps maintain efficiency and prolong the unit's lifespan.

Can this freezer be used for general laboratory storage?

While it can store general laboratory items, its specialised explosion-proof design is specifically for hazardous or flammable substances. Using it for non-hazardous materials might be an over-specification, but it remains a capable laboratory freezer.
