In the shipping industry, explosion safety is arranged by the European Agreement concerning the International Carriage of Dangerous Goods by Inland Waterways, or ADN. This agreement states that a device or product is explosion-safe if the housing provides sufficient protection against moisture and dust (IP55), and if the surface temperatures do not become too high. To meet these requirements, Artidor has developed an IP55 variant of its explosion-safe ATEX Zone 2 air conditioners.
The protection of the exterior unit’s electronic controls from moisture and dust presented a considerable challenge. This power electronics produces a considerable amount of heat and undergoes forced cooling in many cases; fitting it into a housing is therefore not a suitable option because the print will then become too hot, which shortens the life span considerably.
Artidor developed a special solution in which the electronics satisfies all requirements yet the dissipated heat can be properly removed. This solution is combined with proven technologies from ATEX air conditioners to offer an explosion-safe solution that can pass any test.
In addition, the electrical connection and the ventilator motor must also be given attention. From their day-to-day practical experience with ATEX, the professionals from Artidor are accustomed to adjusting components and systems in order to have these permanently meet IP54 requirements. The step to IP55 is then not a big one. Higher IP values can also be achieved upon request.
For more information about the AR-051 series of explosion-safe air conditioners for use in Zone 2, please consult the Artidor website. We are not restricted to a specific brand, so we can also make your air conditioner suitable for use on board or for use in ATEX Zone 2. We also supply the AR-050 Zone 1 air conditioner for use under the harshest of conditions.
