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
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

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

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.

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.

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

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

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

Designed to provide
ventilation in enclosures
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
plates are made from 14 gauge
steel with an ANSI 61 gray
polyester powder finish over
phosphatized surfaces or 316

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.

air filters provide good
arrestment of airborne dust and
dirt. Filter media is composed
of layers of slit and expanded
aluminum providing hundreds of adhesive coated baffle surfaces for
trapping impurities. Impurities are held throughout the depth of the
filter. Washing with warm water will keep the filter clean. To achieve
best results, Hoffman Filter Adhesive is recommended.

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.

CAUTION
These electric heaters are not designed for use in
dusty, dirty, corrosive, or hazardous locations. Portions
of the heater can get hot. Adequate protection must
be taken to protect people from potential burns, and
to protect other components from this heat. Hoffman
recommends this heater only be installed in a totally-
enclosed metal enclosure.
DO NOT INSTALL HEATERS ON WOOD PANELS.

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 (45C ). 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.
