Deterioration of materiel from moisture induced corrosion in sheltertrailersvans STVs during shippingstorage led to the development of a self-contained system which would maintain a relative humidity RH of 40 percent or less within a STV for a period of two years without desiccant changes. This particular system is static because there is not an external means to generate its operation of maintaining the RH of 40 percent or less. Six prototype FBSDH Systems were fabricated under contract number 33700-81-0074. Five units were placed in a field service test at SM-ALCDSTD, McClellan ABF CA and one unit was placed in a field service test at HQ AFLCDSTZ, Wright-Patterson AFB OH. The field test operation was established to verify the prototype design and to determine the actual life of the desiccant charge. The first year results of the two year field test data indicate that the prototype FBSDH system did not verify the design requirement of maintaining a 40 percent or less RH in the interior of the STVs. However, it is anticipated that the FBSDH system will maintain the 40 percent or less RH level when properly installed in a fully refurbished STV or in a new STV.
