ATEX Air Conditioners for use in Zone 2 and 22

In order to guarantee safety, all our explosion proof air conditioner units are delivered with an ATEX certificate and ATEX marking. The ATEX certificate explains why the explosion proof HVAC equipment is in compliance with the ATEX directive. Compliance is based on the following harmonised standards: EN 60079-0, EN 60079-15, EN 60079-11. All equipment is assessed and modified to comply with these ATEX standards.

3D and 3G; ATEX marking

ATEX certification for zone 2 is marked as 3G (gas explosive atmospheres). ATEX certification for zone 22 is marked as 3D (dust explosive atmospheres). Read more on the relationship between ATEX zones and required equipment in our blog.

Is ATEX certification applicable in my country?

ATEX certification is always accepted in Europe, the Middle East, Africa (an additional unit certificate is required in South Africa) and in the Far East. Additional certification may be required in other countries.

Do I need an explosion proof indoor and outdoor A/C unit?

Depending on your situation you might not need both the indoor and outdoor unit to be ATEX certified. In certain situations one of the units can be placed outside of the hazardous area.  Certain air conditioner models work with longer piping, which means the outdoor unit can be placed in the safe area. This saves cost because now only the indoor unit needs to be atex certified.

Our models up to 25kW (85,000 BTU / 7 RT)

Ex-Machinery offers single split, multi split and window air conditioners to be used  not only for cooling, but also for heating purposes in ATEX classified areas.

Did you know that using an air conditioner for heating purposes safes a substantial amount of energy compared to using an electrical industrial heater? A 2 kW air conditioner releases the same heat as an 7.5 kW electrical heater.
