Frequently Asked Questions
Q - Why consider VCI POWDERS for boilers and related components?
A - Vapor Corrosion Inhibitors (VCI) function by releasing or vaporizing into the air space and laying out on all the metal surface a protective film. This technology is ideally suited for dry lay-up (although wet lay-up is possible) and can protect for up to two years! Anytime a boiler or related equipment is non-operable and can be drained, Keeps equipment safe from freezing!
nQ - Can I inspect the boiler with this material inside?
A - The vapors are not hazardous. However, it is suggested that appropriate vessel entry safety procedures be followed. Protective clothing should be worn to avoid/minimize skin contact with any residual product in the boiler.
Q - Can I start-up the boiler with this material inside?
A - Yes, the vci powders are water soluble. Ideally, a fill & flush would be performed prior to start-up but is not absolutely necessary. Boilers with a history of foaming and carryover problems should fill & flush first.
Q - How do I determine dosage?
A - Dosage is determined strictly based on system volume unless otherwise noted.
Q - How do I assess performance?
A - Corrosion coupons have been used or you can simply visually inspect the boiler routinely. A retractable corrosion coupon holder can be rigged if vessel opening is not desired or practical.
