Heat builds up rapidly in enclosed environments,

compromising the performance and life span of

equipment. Like insurance for your electronics, effective

thermal management maximizes the efﬁciency and life

cycle of electrical components. As a leader in thermal

management, Hoffman offers a wide range of solutions

for heating and cooling enclosures, controlling moisture,

and ﬁltering or moving air through an enclosure.

Whether your enclosure is indoors or out, sealed or

open to airﬂow, there’s a reliable, proven Hoffman

thermal management solution available.

Air Conditioners

Sizing and Selection

Before choosing a thermal management solution, you

need to carefully consider the speciﬁcs of your applica-

tion in addition to the following factors:

Fan packages and blowers may introduce ambient

contaminants like oil mist and dust into the enclo-

sure

Heat exchangers cannot cool below the ambient

temperature

Closed-loop air conditioners (this section) can cool

below ambient temperature and reduce humidity

without introducing contaminants

Simple ventilation devices such as louvers or grilles

and ﬁlters are appropriate if maintaining a cool,

constant temperature is not a critical factor

Once you have determined the proper form of cool-

ing equipment you need, selecting the required cooling

capacity is outlined in this section.

How to Read Air Conditioner Catalog Numbers

1. Identiﬁes the type/family of air conditioner and the approximate

height (i.e., CR43 = CR family, about 43” high).

2. This is the air conditioner’s listed capacity in BTU/Hr. (i.e., 06 =

6000 BTU/Hr.)

3. 1 = 115 Volt or 2 = 230 Volt; 4 = 460 Volt

4. 6 = 50/60 Hz or 60 Hz (depending on unit, see Design Data); 5 =

50 Hz

5. Unique set of numbers for each air conditioner which identiﬁes

the accessories on a model.

Sizing Air Conditioners

Determine internal heat load in watts.

Determine the internal heat load produced by

equipment as total operating watts.

1 WATT = 3.413 BTU/Hr.

Determine desired temperature difference in degrees F.

1°C ΔT = 1.8°F ΔT

Determine the ΔT (°F), the temperature difference

between the maximum temperature outside the

enclosure (To) and the maximum desired

temperature inside the enclosure (Ti), which can be

calculated as:

To - Ti = ΔT for air conditioners.

Determine exposed surface area of the enclosure in

square feet.

AREA (ft2) 1 M2 = 10.76 ft2

Calculate the exposed surface area of the enclosure

in Square Feet:

AREA (ft2) = 2[(H” x W”) + (H” x D”) + (W” x

D”)] ÷ 144

where “H”, “W”, and “D” are the dimensions of the

enclosure in inches.

Determine required air conditioner capacity.

(WATTS x 3.413) + [1.25 x AREA (ft2) x ΔT(°F)] = BTU/HR.

Use this formula to determine the required cooling capacity needed

to maintain the desired operating temperature for your enclosure.

This selection procedure applies to uninsulated, sealed, gasketed

enclosures in indoor locations.

All industrial air conditioners are rated at their maximum operating

point. Operating an air conditioner at temperatures below maximum

conditions will result in reduced cooling capacity. In other words,

operating 95°F ambient and 95°F enclosure temperature results in

a 10 percent to 20 percent reduction in the rated capacity. (Note:

full cooling capacity is probably not necessary at lower ambient

temperatures.)

Air conditioners are appropriate for applications in which:

The temperature inside the enclosure must be maintained at or

below ambient temperature

Humidity must be removed from the enclosure

Ambient air contaminants must be kept out of the enclosure

Vortex Cooling Systems

MCL

Application

The compact size of VCool vortex cooling systems make them ideally

suited for small enclosures. Powered by compressed air (typically

100 psig, not to exceed 150 psig), VCool coolers generate chilled

air without refrigerants or moving parts. These coolers provide

exceptional reliability with minimal maintenance in even the most

harsh or dirty environments.

Construction

NEMA models are aluminum

All models include a 5-micron airline ﬁlter, 115V solenoid,

thermostat, and a ducting kit to distribute cold air throughout the

enclosure

Thermostatically controlled to save energy by operating only when

necessary

Cooling capacities to 2500 Btu/Hr (733 W).

Finish

Brushed satin aluminum or stainless steel.

How the VCool Vortex Cooling System Works

The VCool Vortex cooling system uses the principle of vortex

cooling. A vortex occurs when a ﬂuid (air) rotates around an axis,

like a tornado.

A vortex tube creates a vortex from compressed air and then

separates it into hot and cold airstreams.

On entering the VCool tube, the compressed air ﬂow ﬁrst passes

through a vortex generation chamber, which starts the air stream

rotating. The air stream exiting the chamber rotates at speeds up

to 1,000,000 rpm as it is forced along the inner walls of the tube

towards the control valve. At the control valve a small portion of

the air exits through a needle valve as hot exhaust. The remaining

air is forced back through the center of the incoming air stream at

a slower speed, where the slower-moving return air gives up heat

energy to the faster-moving incoming air. The cooled return air

then ﬂows through the center of the vortex generation chamber

and exits through the cold air exhaust port.

Heat Exchangers

Sizing and Selection

Sizing Heat Exchangers

Determine internal heat load in watts.

1 WATT = 3.413 BTU/Hr.

Determine the internal heat load produced by

equipment as total operating watts.

Determine desired temperature difference in degrees F.

1°K ΔT = 1.8°F ΔT °K ΔT = °C ΔT

Determine the ΔT (°F), the temperature difference

between the maximum temperature outside

the enclosure (To) and the maximum desired

temperature inside the enclosure (Ti), which can be

calculated as:

Ti - To = ΔT for heat exchangers.

Determine exposed surface area of the

enclosure in square feet.

AREA (ft2) 1 M2 = 10.76 ft2

Calculate the exposed surface area of the enclosure

in Square Feet:

AREA (ft2) = 2[(H” x W”) + (H” x D”) + (W” x D”)] ÷ 144

where “H”, “W”, and “D” are the dimensions of the enclosure.

Determine required heat exchanger performance rating.

WATTS ÷ ΔT(°F) - [0.22 x AREA (ft2)] = WATTS/°F.

Use this formula to determine the required cooling capacity needed

to maintain the desired operating temperature for your enclosure.

This selection procedure applies to uninsulated, sealed, gasketed

enclosures in indoor locations.

It is recommended that the average “Air In” rating be used when

sizing an application. However, it may be possible to use a lower-

rated heat exchanger by locating the most heat sensitive components

in line with the “Air Out” opening of the heat exchanger. The actual

performance rating of any heat exchanger may vary slightly because

of the airﬂow impedance of the speciﬁc electronics conﬁgurations.

Heat exchangers are appropriate for applications in which:

the electronic controls can operate at a temperature above the

ambient temperature

humidity is not a factor

ambient air contaminants must be kept out of the enclosure

Before choosing a thermal management solution, you

need to carefully consider the speciﬁcs of your applica-

tion in addition to the following factors:

Fan packages and blowers may introduce ambient

contaminants like oil mist and dust into the enclo-

sure

Heat exchangers (this section) cannot cool below

the ambient temperature

Closed-loop air conditioners can cool below am-

bient temperature and reduce humidity without

introducing contaminants

Simple ventilation devices such as louvers or grilles

and ﬁlters are appropriate if maintaining a cool,

constant temperature is not a critical factor

Once you have determined the proper form of cool-

ing equipment you need, selecting the required cooling

capacity is outlined in this section.

When Should You Use a Heat Exchanger?

A heat exchanger is recommended when:

ambient air contaminants must be kept out of the enclosure

the integrity of the enclosure must be maintained

temperature slightly above ambient inside the cabinet is acceptable

humidity is not a factor

When Should You Use a Heat Exchanger?

A heat exchanger is recommended when:

Ambient air contaminants must be kept out of the enclosure

The integrity of the enclosure must be maintained

Temperature slightly above ambient inside the cabinet is acceptable

Humidity is not a factor

Closed Loop Air Circulation

Within the heat exchanger, the recirculated clean air is kept separate

from the ambient airﬂow system. This protects the electronic

controls and prevents shutdowns caused by heat, humidity, dust, and

other contaminants.

aThe “enclosure air in” efﬁciency rating is based on air entering the heat exchanger from the enclosure. The “enclosure air out” efﬁciency rating is based on air exiting the heat exchanger

into the enclosure. All XR exchanger units are rated at 100°F/38°C ambient temperatures with 1500W internal heat load. Heat exchanger efﬁciency will decrease as ambient temperature

and/or internal heat load decreases.

bXR200416012 and XR200426012 do not carry Type 3R rating.

Application Tip

Locate heat-sensitive components in line with the “Air Out” opening

of the heat exchanger.

Determine the required fan/blower size

(volume airﬂow):

Step 1 Select the product family which best ﬁts your

application:

Compact Cooling Fans (economical fan with no ﬁlter)

Cooling Fan Packages (economical fan package with low-density

ﬁlter)

Type 12 Cooling Fan Package

Filter Fan Packages (high-tech fan package with high-density ﬁlter,

for IP54 rating)

Blower Package (centrifugal blower package with ﬁlter for densely-

packed enclosures)

Step 2 Determine the internal heat load in WATTS.

1 WATT = 3.413 BTU/Hr.

Step 3 Determine desired temperature

difference in degrees F.

Determine the ΔT (F), the temperature difference

between the maximum temperature outside

the enclosure (To) and the maximum desired

temperature inside the enclosure (Ti).

To - Ti = ΔT for heat exchangers and fans

NOTE: 1°C ΔT = 1.8°F ΔT

Step 4 Plot your application using the selection graph to the

right.

Find WATTS (internal heat load) on the vertical scale

Draw a horizontal line across to the intersection point with the

diagonal line representing your ΔT

Extend a vertical line down to the horizontal scale to determine

your CFM requirement

Continue the vertical line to identify applicable fan or blower

A sample line is shown in red for a 400 watt heat load and a ΔT

of 20°F, which indicates a 70 CFM airﬂow requirement.

Step 5

Make sure the line intersects the bar which includes the exhaust

grille kit(s) from the product family chosen in Step 1. Remember,

actual air ﬂow going through your enclosure may be less depending

on how densely packed your enclosure is.

Note: Fan output (CFM) is reduced by 10-15% when operated at 50Hz.

Cooling Fan and Exhaust Packages

D85

Application

Designed for use in enclosures where space is limited and reliable

ﬁltered airﬂow is required. The Cooling Fan Package is the air inlet

of a cooling system. It requires at least one Exhaust Package of the

same size and type rating to provide the outlet. Where positive air

ﬂow through the enclosure is not required, Exhaust Packages can be

used on both the inlet and outlet.

NOTE: fan and exhaust packages must be ordered separately.

The Cooling Fan Package is available for both Type 1 and Type 12

enclosures. Type 1 is recommended in UL Type 1 environments

where the ambient air is cool and clean. Type 12 is recommended

in UL Type 12 environments where the ambient air is cool and

may contain small amounts of dust, foreign bodies, and splashing

water. For both Type 1 and Type 12 systems a monthly maintenance

schedule is recommended to ensure optimal cooling performance.

The cooling fan and exhaust packages come with RAL 7035

composite or brushed stainless steel grilles; replacement black ABS

composite and brushed stainless steel grilles are available separately.

The optional EMC Upgrade Kit prepares the fan and exhaust

packages for use where EMC protection is required.

Installation

Fan and exhaust packages can be installed on any surface of an

enclosure. They are most effective when the fan assembly is located

on a lower panel of the enclosure and the exhaust grille is positioned

near the top of the opposite side. This installation assists heat

transfer by causing slightly more turbulence and also prolongs the

working life of the fan since it is located in the path of the cooler air

entering the enclosure.

The height and width of the cooling fans and exhaust grilles can be

rotated 90° for mounting on narrow enclosures. Allow adequate

clearance for servicing the fan when equipment is installed inside the

enclosure and for replacing ﬁlters on both the fan and the exhaust.

Cutout dimensions for both the fan and the exhaust are shown in the

order table. Order the fan and exhaust packages separately.

Features

Cooling Fan Package includes fan, air ﬁlter, composite air plenum,

ﬁnger guard, and grille

Exhaust Package includes air ﬁlter, ﬁlter retainer with integral

ﬁnger guard, and grille

EMC Upgrade Kit includes a grille standoff collar and a special

EMC shielding grille. It can be used with either fan or exhaust

packages that have composite grilles. Cannot be used with stainless

steel grilles.

Optional grilles, available in both brushed stainless steel and black

ABS plastic, can be used with either the fan or exhaust package

Washable foam (Type 1) or disposable (Type 12) ﬁlter in both fan

and exhaust packages provide good arrestment of airborne dirt

with minimal pressure drop. Optional washable aluminum air ﬁlter

is available for Type 1 applications.

•

Durable composite air plenum and grille takes up minimal

enclosure space. Plenum permits even airﬂow through the ﬁlter

for maximum ﬁltering efﬁciency. An integral and removable ﬁnger

guard on either side of the plenum adds safety and convenience.

Air ﬁlters can be accessed for cleaning from outside the enclosure

Rigid fan housing eliminates breakage and grounding problems

Engineered for 50,000 hours of continuous operation without

lubrication or service

Construction

Dynamically-balanced fan impellers molded from polycarbonate

material

4-in. fan is thermally protected and uses permanently-lubricated

ball bearings

6- and 10-in. fans have ball bearing construction and split-capacitor

motors that are thermally protected to avoid premature failure

Fans have leadwires for power connection with ends stripped 1/2-

in. (12 mm)

All mounting hardware and installation instructions are furnished

Filters

Standard Type 1 air ﬁlters are washable foam.

Note: Type 12 air ﬁlters are not washable.

Finish

Fan housing, composite plenum, and grille are RAL 7035 light gray.

Stainless steel grilles have brushed ﬁnish. ABS composite grille is

black.

Application

Permits densely ﬁltered ambient air to pressurize enclosure so that

ambient air cannot be drawn in through poorly sealed doors, panels,

and wireways. Positive airﬂow provides a simple and effective way to

protect enclosed electronics from heat and condensation. Ideal for

clean environments.

Construction

Simple, snap-in mounting

Slim fan grille protrudes only .25” or less from enclosure mount

Fan is completely installed inside plastic housing

Housings are made of heat resistant, self-extinguishing ABS; color

RAL 7042 gray (grille only)

Air ﬁlter is accessible for cleaning or replacement from outside the

enclosure by simply removing the grille cover

Easy to install. Mounting hardware, full-size mounting template,

drawings, and installation instructions furnished.

Filter Fan Package includes the fan with grille, ﬁlter, and ﬁlter

sealing gasket. Exhaust Grille Kits are offered for each Filter Fan

Package and must be ordered separately. Filter sealing gaskets are

supplied with both Filter Fan Package and Exhaust Grille Kit to

achieve an IP54 rating.

Installation

Fan Package should be mounted near bottom of enclosure with the

exhaust near the top of the opposite side. This will ensure complete

airﬂow distribution through the entire enclosure.

Added Protection

With the supplied ﬁlter sealing gasket installed on

both the ﬁlter fan package and the exhaust grille

kit, an IP54 rating can be maintained according to

DIN 40050. This rating is deﬁned as protecting

internal electronics from dust, foreign bodies,

and splashing water.

Application

Provides a maximum amount of cooling air while occupying a

minimum of space. Cool air enters through the intake grille and ﬁlter

and is discharged into the enclosure. Blower operates on 115 volt

AC, 60/50 Hertz, single phase input power. The unit delivers 275

cubic feet per minute (CFM) of air at zero static pressure.

Performance Curve for ADB275 Blower

Construction

16 gauge steel housing

Attractive stainless steel intake grille is easily removed with two

captive thumbnuts

Washable aluminum ﬁlter provides good arrestment of airborne

dirt with minimal pressure drop. Filter has 12 layers of expanded

aluminum which provides hundreds of adhesive-coated bafﬂe

surfaces for trapping dirt and dust particles. (To achieve best

results, Hoffman Filter Adhesive is recommended).

Single phase motor powers the statically balanced blower. Motor is

thermally protected and cooled by incoming forced air.

Direct drive induction motor contains permanently lubricated ball

bearings. Lubricant protects from -20° F to 298° F (-29° C to

148° C).

Rotating components are suspended on neoprene shock-mounts

to minimize noise and vibration

Three-conductor power cord (ﬁve feet long) with molded plug is

internally grounded and strain relieved to the body of the fan

Engineered for 20,000 hours of continuous operation when

properly powered

where excessive internal heat

or excessive moisture is a

problem. Although louvers

cannot keep all moisture out

of an enclosure, gasketing or

sealing the perimeter of the

louver plate reduces problems

associated with moisture

intrusion. These kits may be

easily installed in the ﬁeld

by making a cutout of the

proper size and attaching the

louver plate in place. Louver

Designed to maximize the efﬁciency of all expanded aluminum air ﬁlters. Use of Filter Adhesive doubles

the dust-retention capacity of the ﬁlter. Adhesive contains a low-viscosity water-soluble oil which absorbs

dirt particles trapped on the surface of the ﬁlter. Through the circulation of the oil, a renewed impurity-

absorbing surface is constantly established. Washing with water will remove dust, dirt, and other impurities.

Once the ﬁlter is dry, re-coat with adhesive.

When temperatures dip below the minimally-acceptable ranges for electronics, our electric heaters can raise

the temperature inside enclosures to appropriate levels. Heaters are designed to protect sensitive mechanical,

electrical, and electronic equipment from the harmful effects of condensation and corrosion. Two styles offer

heating powers from10 watts to 800 watts.

The graphs represent a painted steel enclosure mounted in a calm air building interior. The lowest temperature differential between room temperature and

enclosure interior must be 10°F+ to prevent humidity and condensation. For outdoor applications, double the heating power requirement.

Semiconductor Control Panel Heaters (for 10-60 Watt Heating Applications)

Example:

Which electric heater would most efﬁciently maintain a 60°F

temperature in an insulated 24 x 24 x 10 enclosure that is exposed to

a temperature not less than 30°F?

Step 1:

Calculate the total enclosure surface area.

Area (ft. 2) = 2[(AxB)+(AxC)+BxC)] ÷ 144

where “A”, “B”, and “C” are the dimensions of the enclosure.

In our example,

Area = 2[(24x24)+(24x10)+(24x10)] ÷ 144

Step 2:

Using the graphs, draw a vertical line through the enclosure surface

area and determine the temperature rise given by each heater.

For enclosures exposed to windy conditions, heaters should be

oversized by approximately 50 percent.

Step 3:

Select the electric heater that achieves the desired temperature rise.

In our example, the desired temperature rise is 30°F (60°F - 30°F).

The 200 watt heater should be selected since its temperature rise

(35°F) exceeds the requirement.

Step 1:

Plot your application using the graph above.

Find surface area (4 ft.2) on the vertical scale

Draw a horizontal line across to the intersection point with the

diagonal line representing ΔT = 40°F

Extend a vertical line down to the horizontal scale to determine

your total heating power required (W = 45 watts)

•

Step 2:

From the total watts required, subtract the 20 watts from pre-

existing components to arrive at the minimum heater power of 25

watts. The 30 watt DAH301 heater should be selected in this case

since it is the nearest size that exceeds the requirement.

Installation

Hoffman electric heaters should be centered as low as possible on

an interior enclosure panel. This permits the unit to heat the cool air

located at the bottom of the enclosure. For maximum efﬁciency and

longevity, the heater should be mounted in a vertical position with

the terminal block to the bottom and the air outlet openings at the

top in a sealed enclosure free from dust or debris. However, the unit

will also effectively distribute heat if turned 90 degrees. Although

enclosure panels are preferable, heaters may be installed on any ﬂat

sheet metal surface.

DO NOT INSTALL HEATERS ON WOOD PANELS.

Heat sensitive components should not be placed near the heater

discharge area since this air can be quite warm. The clearance range

deﬁnes the space that must be kept free of these components for

proper and safe operation of the heater.

Temperature Control Switches

tHermAl ACCessories

Application

These easy-to-install thermostats are designed to regulate and

monitor air temperature in enclosures that are set up to operate

with heaters, fans, ﬁlter ventilators, heat exchangers, and/or signal

transmitters. Thermostat ATEMNC is speciﬁcally designed for use

with heaters (contacts open on temperature rise), while thermostat

ATEMNO is designed to control fans, ﬁlter ventilators, or for

switching signal transmitters in the event of overheating (contacts

close on temperature rise). Both thermostats have an adjustable

set point range of 30°F to 140°F. An additional label is provided to

convert set point range to degrees Celsius. A preset label is also

provided to cover the set point range label after the thermostat is

put at desired temperature.

When the enclosure reaches the pre-determined set point,

temperature contacts in the thermostat are activated and the fan or

heater begins to operate. Thermostats prolong the life expectancy

of heaters and fans by curtailing their operating hours and also

increase the working efﬁciency of electrical components by exposing

them to fewer contaminants from the surrounding environment.

Connections consist of tubular screw terminals for AWG 14 (0.04

sq. in.). Provision for both panel mounting and DIN rail mounting.

Housing is plastic.

Industrial Corrosion Inhibitors

Hoffman corrosion inhibitors protect

Interior components of electrical enclosures, boxes, consoles, and

wireways

Interior components of electronic enclosures

Electrical and electronic equipment and controls

Parts and components that are packaged in crates during shipping

and storage

Switch gear and relay cabinets

Interiors of pipes, conduits, and fuse boxes

Process control computers, instruments, and recording devices

Tool chest interiors and contents

Equipment stored at construction sites

Chief Advantages

Protects against salt and high humidity

Eliminates the need of oiling, plating, or dipping metal

Puts protected equipment to use immediately without degreasing

or coating removal

Provides durable protection for up to 12 months

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 Hoffman corrosion inhibitors is in

excess of one year. However, inhibitor life expectancy is shortened

by approximately 25% when exposed to temperatures above

104° F (40°C). This product is not recommended for use where

temperature exceeds 199°F. Ventilated enclosures or enclosures not

sealed properly, as well as frequent door openings, also shorten the

product life. Additional inhibitors should be used if these conditions

exist. 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 feet

(.46 meters). Protection of long narrow enclosures can be achieved

with tape or multiple inhibitors.

Storage and Handling

Each 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 ). Recommended shelf life under normal conditions is

one year. 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 in. x 1.25 in. x 3.00 ft. (6mm x 32mm x 76mm)

AHCI60R Tape protects sixty cubic feet of enclosure volume per

roll. Use approximately 2.50 in. (6.3cm) 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. (6mm x 19mm x 3.6m)

AHCI240R Tape protects 240 cubic feet of enclosure volume per

roll. Use approximately 1.00 in. (2.5cm) 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. (6mm x 51mm x 6.1m)

AHCI5E Emitter protects ﬁve cubic feet (142 liters) of enclosure

volume for approximately one year. Emitters contain additional red

metal (non-ferrous) inhibitors.

Size: 2.50 in. (diameter) x 1.50 in. (high) (63mm x 38mm)

AHCI10E Emitter protects ten cubic feet (283 liters) of enclosure

volume for approximately one year. Emitters contain additional red

metal (non-ferrous) inhibitors.

Size: 2.50 in. (diameter) x 2.00 in. (high) (63mm x 51mm)

AHCI238S Spray is a non-conductive, nonﬂammable, vapor phase

ﬁlm and is non-toxic. It has essentially neutral pH value. Application

provides instant protection against corrosion. Spray is water soluble

and can be easily ﬂushed away with water if desired. This product

should be kept from freezing, and has a shelf life of 2+ years in

normal warehouse conditions.
