Desiccant
Desiccant, mostly silica gel, is the name usually given to water-absorbing materials as used in the
special packing. The desiccant is in packs of highly-permeable (for water vapour) and strong material
(e.g. natron crepe paper) which are placed in the transport package.
Desiccant pack
The following drying-agent packs are used for transport packing:
• MTU-No. 49542 desiccant 125 g = 4 units
• MTU No. 49543 desiccant 259 g = 8 units
• MTU-No. 49544 desiccant 500 g = 16 units
• MTU No. 49545 desiccant 1000 g = 32 units
Calculation of required desiccant
The amount of units placed in the special packing depends on th
e climatic c onditions and type of storage at
the place of destination. The minimum amount of units to be used is calculated as follows:
Climatic zone Per m² laminated
aluminum foil surface
(A)
Per kg auxiliary packing
materials (APM)
Desiccant units (DU)
A
Europe (excluding Russia)
6xA 17 x APM
= DU per shipment
package
B
USA
Canada
Mediterranean
Near East
8xA 20 x APM
= DU per shipment
package
C
Russia
South and Middle America
Middle and Far East
17xA 20 x APM
= DU per shipment
package
Procedure
1. Measure surface A of the laminated aluminum foil for the packing.
2. Weigh the packing material (e.g. wood, corrugated cardboard, etc.) necessary to support
and protect the engine within the special packing envelope.
3. Determine which climatic zone(s) the protected engine will be transported through and finally stored in.
4. Calculate the required desiccant (DU).
