Big Volumes, Hot Ports, Cargo That Spoils and Corrodes.
Spain is one of Europe's largest vehicle producers and, at the same time, a giant in fresh and processed food, wine, olive oil and ceramic tiles. It is a combination that makes moisture a broad-front threat: a sealed car corrodes, a pallet of produce rots, a case of wine loses its labels and a crate of glazed tiles arrives streaked. What ties these very different cargoes together is that they nearly all leave through hot Mediterranean ports, so the air sealed into the container starts warm and heavy with water before the voyage even begins.
That heat is the crux. A box loaded under the Valencia or Andalusian sun and then carried across the tropics, or simply trans-shipped at Algeciras and sent on, cycles through a punishing day-night swing that condenses the trapped moisture onto the steel and the cargo. BENZ sizes the calcium chloride to that real, warm starting humidity and the route using the DIN 55473 unit method, and specifies nitrite-free clay where finished surfaces or food cannot tolerate any chemical contact.
