Mould and Rust in Storage: Why AC Won't Fix It

If boxes are softening, metal is rusting and mould appears on the walls of your store, air conditioning alone may not be the answer. We cover what AC looks at, why relative humidity rises in cool air and how humidity is controlled.

  • AC looks at temperature; once on target it stops, while the moisture often stays.
  • Relative humidity rises as air cools, so a cool closed store can suit mould and rust.
  • Cardboard takes up moisture, softens and loses strength; when the bottom box gives way the stack is at risk.
  • Quality and safety in hazelnuts, germination in seed, corrosion on metal and paper in archives are all affected.
  • Cooling and dehumidifying do not replace each other; the unit is chosen by the moisture source and the store.
