Protec offers two advanced methods for corrosion protection: dry air protection, and vapor/contact corrosion inhibitors. All Protec systems are environmentally friendly and safe to use. The technologies that Protec will recommend for your situation will be designed specifically to meet your requirements. In many cases, Protec’s advanced technologies are combined in one cost-effective system. VCIs are a class of chemicals that prevent corrosion by blocking electrochemical reactions at the molecular level. Protec provides them in a number of convenient forms, including time release vaporizers, sprays, plastic bags and films, powders, oil additives and coatings. VCIs adsorb onto the metallic surfaces of the equipment, where they prevent corrosion for up to two years. VCIs are environmentally friendly and create no safety hazards for employees. They contain no toxic substances, such as nitrates, chromates or VOCs (volatile organic compounds). Corrosion cannot occur when parts are stored in environments where the relative humidity is held below 40%. This is because low relative humidity precludes condensation on the metallic surfaces of the parts. Since the presence of moisture is essential for the chemistry of corrosion to occur, dry air provides an absolute deterrent.   To create dry air, Protec offers a complete line of desiccant dehumidifiers to control environmental conditions in both large and small storage areas or warehouse buildings. These state-of-the-art dehumidifiers can provide dry air even at sub-zero temperatures. Designed to run continuously with little maintenance, they can be the heart of an advanced corrosion control system. Dry Air Protection can be an excellent choice for large well-sealed environments. Equipment in storage requires no additional protection and can be accessed easily. Dehumidifying air creates no environmental or safety hazards, eliminates mold and mildew, and generally provides for a more sanitary environment.
