What does ATEX certification mean?

ATEX (ATmospheres EXplosibles) is the 2014/34/EU European Union directive that defines the design and manufacturing standards for equipment used in explosive environments. BEAR series fans are manufactured in compliance with this directive.

What is the difference between Zone 1 and Zone 2?

Zone 1 defines areas where explosive atmospheres may occasionally occur during normal operating conditions; Zone 2 defines areas where explosive atmospheres may only occur under abnormal conditions and for short periods.

Which gas groups do you manufacture fans for?

The BEAR series is manufactured in models suitable for gas groups IIA (propane, methane), IIB (ethylene) and IIC (hydrogen, acetylene).

Can an ATEX fan be integrated into an existing system?

Yes, ATEX certified fan integration into existing ventilation systems is possible. However, duct, connection and automation components must also be checked for ATEX compliance.

ATEX Explosion ProtectionSolutions

In industrial areas where there are explosive gases, steam, fog, solvents, VOCs or flammable dust, the ventilation system is not a standard air transfer equipment; It is a direct part of facility security. Choosing the right fan in chemical and petrochemical plants, fuel filling areas, paint shops, flour-sugar-powder processes, pharmaceutical production and similar high-risk environments; It is critical to control the risks of sparks, static electricity, hot surfaces and gas accumulation.

NOVVES provides safe air management in explosive atmospheres with fan, damper and filtration solutions specific to ATEX and Ex-Proof applications. BEAR, NAUTILUS, HOUND, KOI and ELEPHANT product families; It offers an integrated solution for safe exhaust, VOC discharge, flammable dust control and static discharge protection by being designed according to zone class, gas/dust character, process temperature and maintenance requirements.
