How They Work
Each inhibitor contains a special chemical combination that
vaporizes and condenses on all surfaces in an enclosed area.
Vapors will redeposit as needed in the event of condensation
of moisture on surfaces. These vapors reach every part of an
enclosure, protecting all interior components. Spraying, wiping
or greasing are not required. This eliminates precoating, special
wraps and drying agents. Protection is effective even in salt-water
atmospheres. The AHCI5E and AHCI10E emitters have additional
red-metal inhibitors for further protection. Enclosures containing
corrosion inhibitors must be reasonably sealed.
Life Expectancy and Usage
The normal useful life-span of nVent HOFFMAN corrosion inhibitors
is in excess of one year. However, inhibitor life expectancy
is shortened by approximately 25 percent when exposed to
temperatures above 104 F (40 C). This product is not recommended
for use where temperature exceeds 199 F. Since Hoffman corrosion
inhibitors are vapor-phase protective, all surfaces to be protected
should be accessible to the vapors. The maximum distance the
vapors can travel is approximately 1.50 ft. (.46 m). Protection of
long, narrow enclosures can be achieved with tape or multiple
inhibitors.
Storage and Handling
Each nVent HOFFMAN corrosion inhibitor is individually packaged
in a resealable bag for maximum effectiveness at the time of usage.
Corrosion inhibitors should be stored at temperatures not exceeding
120 F (45 C ). Hoffman corrosion inhibitors are not returnable.
When determining the proper corrosion inhibitor for your
application, assume the enclosure volume to be protected is greater
than calculated if (1) cabinet doors are opened frequently, (2)
cabinet is located in an extremely corrosive area and/or (3) cabinet
length divided by depth is greater than four.
AHCI1DV
Foam device protects one cubic foot (28 liters) of enclosure volume
for approximately one year.
Size: .25 x 1.25 x 3.00 in. (6 x 32 x 76 mm)
AHCI5E
Emitter protects 5 ft.
3
(142 liters) of enclosure volume for
approximately two years from the date of manufacture. The
useful life (protection) depends on the moisture surrounding the
application. Severe environments recommend no more than 3
months before replacing, less severe recommend no more than
6 months before replacing. Emitters contain additional red metal
(non-ferrous) inhibitors.
Size: 2.31 in. (diameter) x 0.81 in. (high) (59 mm x 21 mm)
AHCI10E
Emitter protects 10 ft.
3
(283 liters) of enclosure volume for
approximately two years from the date of manufacture. The
useful life (protection) depends on the moisture surrounding the
application. Severe environments recommend no more than 3
months before replacing, less severe recommend no more than
6 months before replacing. Emitters contain additional red metal
(non-ferrous) inhibitors.
Size: 2.31 in. (diameter) x 1.38 in. (high) (59 mm x 35 mm)
AHCI60R
Tape protects 60 ft.
3
of enclosure volume per roll. Use
approximately 2.50 in. (63 mm) of tape per cubic foot (28 liters) of
enclosure volume to be protected. Each roll of tape is packaged
individually in a resealable bag.
Size: .25 in. x .75 in. x 12.00 ft. (6 mm x 19 mm x 3.6 m)
AHCI240R
Tape protects 240 ft.
3
of enclosure volume per roll. Use
approximately 1.00 in. (25 mm) of tape per cubic foot (28 liters) of
enclosure volume to be protected. Each roll of tape is packaged
individually in a resealable bag.
Size: .25 in. x 2.00 in. x 20.00 ft. (6 mm x 51 mm x 6.1 m)
