Our explosion-safe AR-052 air conditioners are based on the Daikin range of air conditioners and are made to safely ensure a good climate in an area where a release of gas, vapor or mist could possibly cause an explosive atmosphere (Zone 2). The units are widely used in office spaces, offshore temporary living quarters, crane cabins and at the storage of chemicals and flammable substances.

The air conditioners are explosion-safe and certified in accordance with European directive 2014/34/EU (ATEX 114) and are CE marked.

Depending on the required power, a wall-mounted or ceiling-mounted indoor unit can be selected. Duct or cassette model indoor units can also be supplied.

The systems can consist of a combination of explosion-safe and non-explosion-safe units, depending on the zoning of the area where the units are placed. During the conversion of the units to explosion-safe, the greatest possible attention is given to the maintainability and ease with which the units can be installed. The functionality remains completely intact.

To extend the service life under severe coastal and offshore conditions, the aluminum fins of the condenser and the copper tubing can be provided with a protective coating.
