Desiccant cartridges for precision, electronic and optical equipment
Desiccant cartridges are used in sensitive instrumentation controls and controls in other highly sensitive optical and electronic equipment – particularly military applications – to protect against moisture, corrosion and fungi. The cartridges comply with the German Armed Forces technical delivery specifications (“Technische Lieferbedingungen”) TL4440-0007 (VG 95239), and have a NATO Stock Number (NSN).
Residual moisture which exists even in environments of extreme impermeability, as well as moisture that enters as a result of a leak, can condense through cooling, causing rusting or fungi, which is in turn particularly harmful to glass, reducing its lifespan. This is where desiccant cartridges come in.
Packaging
The desiccant cartridges are additionally delivered in sealed protective packaging to ensure none of their effectiveness is lost during transportation and storage. For optimum shelf life, store the cartridges in their original heat-sealed packaging in a dry place at room temperature.
