The application of Envelop covers makes it possible to keep equipment ready for use with less time-consuming maintenance and change of spare parts. Thorough field testing has provided positive results with up to 75 % savings in labor hours with regard to maintenance. Envelop protective covers is a patented method for a simple and efficient corrosion protection.
To have the best effect each Envelop cover is tailor made to suite the specific requirement/equipment. An Envelop protective cover consists of 4 layers of composite structure working together to protect critical equipment from corrosion. The multilayer cover protects metal by drawing humidity out from the underside and by forming a molecular film on the surface.
The cover is designed as follows:
- Surface/Outer layer
A strong, flexible, waterproof material which lets humidity out, but is resistant to water drops from the outside.
- Inner layer
The innermost layer which is in contact with the metal surface Hydrophobic material which form a hydrophobic structure which in turn rapidly draws away/absorbs the water from the metal surface.
- Absorbing interior lining
A material with excellent absorbing properties which stores water and only returns it to the surroundings when the humidity is below 100 %, will also reduce.
- Anticorrosive layer
A layer of corrosion inhibitors (VCI) which will create an anticorrosive atmosphere beneath the cover by forming a molecular film on the metal surface.
