Dimensioning by Rule of Thumb for Desi Dry and DIN Dry
To assess the amount of desiccant required, the following rule of thumb can be used for a simple calculation:
Amount of water to be absorbed in grams x 10 = amount of desiccant required in grams
Caution: The products of Master Dry and Sea Dry require less desiccant because they can absorb more moisture (see diagram on page: Master Dry / Sea Dry)
Machinery elements made of metal without packaging materials (cardboard, wood) In a wooden crate 1 m³ in size lined with barrier-layer foil during a four-week period of transport and storage
|Die The machinery elements are made of metal:||Moisture in the merchandise ||approx 0 g|
|There are no moisture-retaining materials enclosed (cardboard, wood):||Moisture of the materials enclosed||approx 0 g|
|According to the Climate Chart, in a wooden crate 1 m³ in size, at 45° C there may be a max. of 65.44 g of water:||Moisture in the air||approx 65.44 g|
|The permeability of the barrier-layer foil to moisture during a four-week period of transport or storage is negligible. It is very low in comparison with the moisture in the air:||Moisture through outer envelope||approx 0 g|
This example calculation yields moisture amounting to approx 65 g of water.
Result: 65 g of water x 10 = 650 g of desiccant
During long periods of transport or storage, the influence of moisture through the envelope (foil) becomes ever greater.
