Frequently Asked Questions
•Q - Why VCI technology 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, VCI technology is an excellent choice.
•Q - 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 products 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.
