Almost all airline companies’ maintain / store engines as standby for quick replacement. These engines are very expensive and are usually needed in emergencies, in case of engine failure.
The Jet Engines are generally stored in a room in / near the hangars at Airports. While in storage, they are damaged due to corrosion. Ferrous material like iron and steel corrode in presence of moisture. Electronic equipment and components also sufferfrom micro-corrosion.
Corrosion does not occur in dry air. It is the invisible water vapour which is always present in the air, which causes corrosion of metal components and parts, in storage.
Water vapour condenses, on any surface, colder than the dew point temperature of the surrounding air mass. Also, sudden changes in temperature, within the room, affect the internal humidity environment and lead to condensation on any surface. This subsequently leads to corrosion.
The comparative rates of corrosion in relatively clean and polluted air. The critical humidity level which is at 45% is approximately same for clean and polluted air, however the rate of corrosion is faster where surfaces are exposed to polluted air in combination with high relative humidity.
To prevent corrosion, the relative humidity of the air needs to be controlled to a level where it not only prevents condensation but is reduced to a critical level below which corrosion does not occur. As a general rule, rust and other oxidizing type corrosion reactions will not occur if the relative humidity in the area is maintained at or below 40% RH. Materials or product residing in this atmosphere need not be coated with oil or other surface protecting materials, and can thus be kept in ready-to-use condition
This significantly reduces the cost of painting and other maintenance normally required to control corrosion.
Most metal parts do not need to be stored in areas which need temperature control. Thus humidity control through desiccant dehumidification is a much more economical method than air conditioning.
Corrosion can be eliminated by controlling the moisture levels to less than 45% RH at ambient condition in the storage area. Humidity control by dehumidifying such storage areas ensures that the engines in storage do not get corroded.
… Safe, cost effective, quickly assembled humidity control housing for safe storage of small equipments like engines, gear boxes, small arms, ammunition, optics, ration, documents, uniform, metal components, etc.
The Bry-Air Enviroliner is the ideal solution to humidity related storage problems. The Enviroliner is a custom made, modular PVC store house, integreting a Bry-Air Dehumidifier which can convert any space in whole or in part, into cost effective humidity controlled storage area, without any special building requirement. All that is needed is a floor and a ceiling. Equipment and material stored in Enviroliner is protected against damaging effects of moisture corrosion/rust, mold, fungus, etc.
Bry-Air Dehumidifiers can maintain RH as low as 1% or even lower at a constant level, regardless of ambient conditions during production, processing, storage and packaging.
Bry-Air Dehumidifiers are CNC fabricated with powder coated finish incorporating high performance, metal silicate, fluted media.
Bry-Air Dehumidifiers help reduce the relative humidity to the desired constant level, by removing moisture from the air, most effectively and economically. They can be successfully used, for a wide range of applications, in industrial manufacturing, processing, drying, storage and packaging.
