Water Treatment

The VpCI® Difference

In a recent article for "The Analyst — the Voice of the Water Treatment Industry", Ashish Gandhi, Water Treatment Sales Manager, wrote about "Unique Water Treatment Applications of VpCI®'s. The following are some of the highlights. Complete text is available on our web site (www.CortecVCI.com).

"The new (VpCI®) method for laying-up boilers and cooling towers utilizes a unique blend of vapor phase corrosion compounds and contact corrosion compounds in convenient water-soluble polyvinyl alcohol (PVA) bags. VpCl™'s have the unique ability to control corrosion in the water treatment system. VpCl™'s distinguishes themselves from the conventional contact corrosion inhibitors since they provide:

1. Protection in three phases: vapor phase, liquid phase, and liquid vapor interface.
2. Biodegradable and environmentally friendly solutions free of nitrites, phosphates, chromates, and heavy metals.
3. Economical solutions for protecting cooling towers, closed loop systems, and boilers during the interim period, seasonal lay-ups or long-term lay-ups.
4. Economical solution for niche applications that requires vapor phase protection.
5. Protection in the presence of moisture and other corrosive environments by forming a corrosion inhibiting monomolecular layer on the metal surface.
6. Savings by eliminating the use of expensive cleaning chemicals.
7. Increased worker safety and efficiency due to the non-toxic, nonhazardous nature of the products packaged in convenient watersoluble bags.
8. Easy start-ups at the end of the lay-up period without any clean up required.
