These AHUs are intended for use in an ATEX zone 2 environment.
The acronym #ATEX stands for ATmosphère EXplosive. It refers to a working environment where there is a high risk of explosion, due to the presence of particularly flammable materials: fuel, combustibles, gases...
The environments most at risk are for example certain #agro-food factories, #chemical plants, #airports...
The newly designed AHUs will be used by a heat pump factory in their R&D department to test their products and simulate gas - propane leaks.
They are black because the gelcoat is formulated with carbon nanoparticles to give them an antistatic property that reduces or eliminates the build-up of electricity and thus avoids the risk of sparking and explosion when in contact with a gas!
