ADCOA has had long experience in working with the major utilities and power circuit breaker manufacturers in the development and production of SF6 Circuit Breaker Desiccant Bags. These bags are designed to be suspended in the breaker housings to adsorb water vapor and other arc products.

Our Power Circuit Breaker Desiccant Bags are made from self extinguishing, non-dusting Dacron. In most of these bags, we utilize Type 4A Molecular Sieve as the active desiccant. Type 4A has been found to be the preferred desiccant for this application.

Circuit Breaker Desiccants have become a mandatory maintenance item for most breakers in use today. The 4A Molecular Sieve is a synthetically reconstituted alumina silicate which is generated and processed under stringent conditions to establish exact pore dimensions within the lattice of the molecules crystalline structure. These pores are created by removing the water of crystallization from the compound. In its dehydrated state, the Molecular Sieve exhibits a tremendous affinity for water and smaller hydrocarbons, adsorbing over twenty percent of its weight of such contaminates. The incorporation of Type 4A into the static drying system essentially eliminates the danger of arcing caused by gas contamination in the breaker housing.

ADCOA also offers a full range of desiccants for use as a bulk moisture drying bed in the circuit breaker door. These desiccants include Activated Alumina and Silica Gel. We package all of our Circuit Breaker Desiccant Bags in heat-sealed, vapor-proof foil enclosures to prevent contamination of the product prior to use. Packaged in this manner, we guarantee a minimum shelf life to two years.

APPLICATION
Desi-Pak® is a cost efficient desiccant that will protect the contents of a sealed container until it is opened. The contents of a sealed container will remain free from mildew or corrosion and will be in the same condition as when packaged for shipment or storage.

DUSTING
Desi-Pak® is packaged in tear resistant, dustproof bags.

PERFORMANCE
Desi-Pak® exceeds the requirements of MIL-D-3464D in actual performance. It exceeds the water adsorption of Silica Gel at various humidity levels. Placed within a sealed package or container to protect goods/products from moisture damage. Used with electronic parts, aerospace missile components, computer components or any environment that is sensitive to dust. Desi-Pak® is used by both general purpose and non-dusting purposes. Meets military specification MIL-D-3464E.

Note: Each container of Desi-Pak® includes an MS26507-1 humidity indicator card to insure that the desiccant is active when recieved.

APPLICATION
