Use of Electric Heaters
In Hazardous Locations
Introduction
Hazardous locations are those areas where a potential for
explosion and fire exists due to the presence of flammable
gases, vapors, pulverized dusts or ignitable fibers in the
atmosphere. Hazardous locations are created from the normal processing of volatile chemicals, gases, coal, grains, etc.,
or from the accidental failure of storage systems for these
materials.
Open flames are not permitted in these locations. The use
of electric heating equipment is permitted with two major
restrictions: 1) The surface temperature of the equipment
cannot exceed the ignition temperature of the hazardous
atmosphere and 2) all arc and spark producing devices must
be isolated from the atmosphere in an appropriate enclosure.
Both people and equipment in hazardous locations can be
heated safely and economically with electric heat. Electric
heating is typically much less expensive to install and maintain than comparable remote oil or gas fired heating systems.
National Electrical Code Classification
Articles 500 through 516 of the National Electrical Code deal
with the definition of hazardous areas and the use or design
of electrical equipment used in these locations. Electric
heating equipment for hazardous areas is specified based on
the NEC class, division, group and ignition temperature or
the alternate class and zone classification.
Class
in the atmosphere. Typical locations would include coal fired
power plants, coal preparation/coal handling facilities, coal
mines, grain elevators, flour and feed mills, packaging and
handling of pulverized sugar and processing and storage of
magnesium and aluminum powder.
Class III – This third classification is primarily a fire hazard where fibers or flyings suspended in the air create a
hazard. This would include small pieces of thread-like fiber,
sawdust, lint, etc. Typical applications would include textile
mills, woodworking plants, cotton gins, cotton seed mills
and flax producing plants.
Division
Class I, Class II and Class III areas are further defined in
terms of when the hazard occurs. Division 1 and Division 2
occurrences are summarized below.
Division 1 – If the hazard is expected to be present under
normal conditions, such as a production or processing facility, the occurrence is designated Division 1. The hazardous
atmosphere may be present continuously, intermittently,
periodically, or during normal repair or maintenance operations. Division 1 occurrences also include locations where
a breakdown in the operation of processing equipment
results in the release of hazardous vapors.
Division 2 – If the hazardous material is normally expected
to be contained within a closed area, system or container,
and would enter the ambient atmosphere only under an
abnormal failure, then it is referred to as a Division 2 occurrence.
Hazardous locations are divided into the three general classes of vapors/gases, dusts and fibers.
Class I – Locations where the potential for explosion and
fire exists due to the presence of flammable gases or vapors
in the air. Typical Class I locations include oil or natural gas
drilling rigs, petroleum refining or pumping facilities, petrochemical plants, wastewater/sewage treatment plants,
solvent extraction plants, paint spraying booths, locations
where open tanks or vats of combustible liquids are present
and storage areas for flammable materials.
Class II – Locations where the potential for explosion exists
because of finely pulverized flammable dusts suspended
3
Use of Electric Heaters
In Hazardous Locations
Group
The nature and explosive characteristics of the hazardous
material are defined by the NEC group to which it is assigned.
Class I – Hazardous vapors/gas locations include chemicals and
other materials that have been divided into four groups based
on their ignition temperature and explosive characteristics.
(Groups A, B, C and D)
Class II – Hazardous dust locations are divided into three
groups based on their ignition temperature and electrical conductivity of the suspended particles.
Group E – Atmospheres containing metal dust, such as aluminum or magnesium.
Group F – Atmospheres containing coal, charcoal or coke
dust.
Group G – Atmospheres with grain, flour, starch, combustible
plastics or chemical dust.
Class III – Locations have no group definitions.
Class I, Zone 1 – Locations in which ignitable concentrations of
flammable gases or vapors are likely to exist, may exist frequently or exist as a result of equipment breakdown or faulty operation. Applies to locations adjacent to a Class I, Zone 0 location.
Class I, Zone 2 – Locations in which ignitable concentrations of
flammable gases or vapors are not likely to occur under normal
operation, exist only for a short period or exist only as a result of
accidental failure, such as rupture or breakdown of the container
or system, abnormal operation of equipment, failure or abnormal operation of the ventilation equipment. Applies to locations
adjacent to a Class I, Zone 1 location.
Material Groups
Group IIC – Atmospheres containing acetylene or hydrogen.
Equivalent to a combination of Class I, Group A and Class I, Group
B as described in NEC Article 500.
Class and Zone Classifications
Group IIB – Atmospheres containing acetaldehyde. Equivalent
to Class I, Group C as described in NEC Article 500.
Ignition Temperature
Group IIA – Atmospheres containing acetone, ammonia, ethyl
alcohol, gasoline, methane or propane. Equivalent to Class I,
Group D as described in NEC Article 500.
All electrical equipment is designed not to exceed the ignition temperature of the hazardous atmosphere. The maximum surface temperature for electric heaters is defined by
the NEC.

Special Requirements for Electric Heating Equipment used in Hazardous Areas
Electric heating equipment can be economically designed and
safely used in hazardous areas if the following special requirements are observed.
1. The surface temperature of the electric heating equipment
cannot exceed the ignition temperature of the hazardous atmosphere. To insure that the proper heater has
been selected, it is essential that the correct NEC Ignition
Temperature Code be specified.
If the temperature code selected is too high, the electric heating
system may operate above the ignition point of the application,
creating a potentially hazardous condition.

heating elements are immersed in a nontoxic, inhibited,
propylene glycol heat transfer fluid that provides freeze protection down to -49°F (-45°C). The heat exchanger is hydrostatically tested at 350 psig. A pressure relief valve provides
excess pressure protection and is set at 70 psig.
is rated for Class I, Groups C and D, Class II, Groups F and G.
The minimum operating temperature is -14°F (-25°C) and the
minimum storage temperature is -49°F (-45°C). Optional
motor ratings are described on page 9.
Fan Motor Assembly – Consists of an explosion-proof
motor fitted with an aluminum fan blade. The motor has
double-shielded, permanently lubricated ball bearings and
automatic reset line breaking thermal overload protection.
Motors furnished on standard units operate at line voltage
and are prewired to the control enclosure so separate field
wiring to the motor is not required. The standard motor
Controls – Factory mounted on the unit heater. Standard builtin controls include automatic and manual reset overtemperature cutouts, controlling magnetic contactor, and 24-volt
control circuit transformer housed in a NEMA 7, 9 cast aluminum enclosure.

use in corrosive applications.
H E A T E R S
• Low Cost: The design offers the most economical solution for heating small Class I, Group D hazardous areas.
It is a cost effective alternative to the use of explosionproof convection heaters.
E X P L O S I O N - P R O O F
236 Series
• Optional Marine Duty Construction: Ideal for shipboard
use where size, weight and corrosion resistant construction are critical.
Standard Construction Features
Heating Elements – Industrial grade, Type 304 stainless
steel finned tubular heating elements are manufactured
by HEATREX.
Terminal Enclosure – A NEMA 7, 9 cast aluminum enclosure
with a threaded bottom cover permits easy access to the
built-in controls from underneath the heater.
Housing – Round, 16-gauge stainless steel shroud.
Grilles – An adjustable stainless steel louvered outlet grille
directs airflow 45° up or down and a heavy gauge stainless
steel rear grille protects against accidental contact with the
fan blade.
Stainless Steel Swivel Mounting Bracket – Supplied as
standard with all 236 Series explosion-proof unit heaters.
This multi-purpose bracket can be used for either wall or
ceiling mounting.
Built-In Controls – Include primary and secondary automatic reset overtemperature cutouts, controlling contactor, and a time delay relay which keeps the fan running
to cool the heating elements after they have been deenergized.
Fan Motor Assembly – Consists of a 120-volt, 1-phase 60
hertz motor fitted with an aluminum fan blade. The totally
enclosed motor is UL Listed for Class I, Group D applications and includes permanently lubricated ball bearings
and built-in thermal overload protection. The motor is factory wired into the enclosure to reduce field wiring, but
requires a separate 120-volt power supply.

HEATREX’s explosion-proof convector is designed to
provide a heavy duty and corrosion resistant heat
source. Features include:
• Wide Selection of Sizes: Four compact sizes to fit any
space with ratings from 500 to 9,500 watts.
• Sloped Top Cabinet: Prevents objects from being set
on top of the convector, which can restrict airflow and
cause overheating.
• Single and Three-Phase: Unique design provides single
and balanced three-phase loads in a single element.
• Gas and Dust Atmospheres: Three listings cover the
entire field, two for hazardous gases and vapors and
one for dust particles.
• Wet Locations: All unit sizes available with iriditecoated elements and powder-coated frames for NEMA
3 wet locations.
Standard Construction Features
Element – Grade A Nickel-Chromium heating coils are insulated with ceramics and magnesium oxide from the copper
heater tube and fitted with large aluminum fins locked in
place.
Cabinet – Heavy gauge galvanized steel cabinet is painted
with a beige powder coat for durability. Cabinet should
be mounted at least 6 inches (152 mm) above the floor.
Factory-furnished wall brackets make installation easy.
18
Thermal Protection – A linear limit, automatic reset thermal cutout is built into every unit.
Complete Electrical Package – For larger single-phase and
all three-phase units, a built-on contactor and transformer
option package are available.
254 Series
All single-phase heaters rated over 22 amps or 277 volts
and all three-phase heaters require a magnetic contactor. Some electrical combinations will also require a
control transformer. To simplify field installation, these
Code
accessories are factory-mounted on the heater cabinet and
factory pre-wired (not available on Size 1 convectors).

Washdown/Corrosion Resistant Unit Heater
• Built-in Controls: All necessary safety and temperature
controls are included in a single package. Components
and motor are factory-wired to a single terminal block
for field wiring, eliminating the chance for field error and
reducing installation costs.
• Single Point Electrical Hook-up: Heater, fan motor and
controls are all connected to the same branch circuit.
• Corrosion Resistant: Stainless steel construction, powdercoated aluminum fan blade and nonmetallic NEMA 4X
terminal enclosure resist corrosion found in sewage treatment plants, swimming pool areas, car washes, paper
mills and marine installations.
• Washable: This watertight construction can be hosed
down without disconnecting the heater, which makes it
ideal for coal handling areas, steel mills, foundries, ships,
wood finishing plants, cement, sand, grain and food processing facilities.
Standard Construction Features
Heating Elements – Industrial grade, Type 316 stainless steel
tubular elements with stainless steel fins, manufactured by
HEATREX.
Control Enclosure – The non-metallic enclosure, which
houses the element terminals and built-in controls, will
not rust and meets NEMA 4X hose-down requirements.
Fan Motor Assembly – Totally enclosed, epoxy coated, UL
Recognized motor with permanently lubricated ball bearings
for longer life. Designed to resist moisture and corrosion.
Factory-wired to NEMA 4X enclosure. Fitted with a powdercoated, aluminum fan blade suitable for corrosive salt spray
environments.
Built-in Controls – Include automatic reset overtemperature cutout, fan delay relay, controlling contactor, transformer for 24-volt control circuit, terminal block for field
wiring and a separate motor contactor (when required).
Housing – Heating elements and motor are enclosed in a
round, heavy 16-gauge stainless steel shroud.
Inlet/Outlet Grilles – Adjustable, stainless steel, louvered
outlet grille can be rotated 90° to direct airflow up, down,
left or right. Heavy gauge, stainless steel rear grille protects
against accidental contact with the fan blade.

238 Series
HEATREX’s industrial unit heater is designed for maximum heating performance in non-hazardous and noncorrosive environments. Features include:
• Unique Design: Round design of the industrial unit heater
provides uniform airflow over the elements to prevent
hot spots and ensure even discharge temperatures.
Circular stainless steel finned tubular elements have a
longer life due to lower operating temperatures.
• Built-in Controls: Heaters are completely assembled with
all electrical components built-in at the factory to reduce
installation costs.
Applications
•Aircraft Hangars
•Power Generating Stations
•Entryways
•Pump Houses
•Factories
•Service Stations
•Garages
• Improved Performance: High CFM’s and air throw up
to 50 feet promote air circulation within the space. More
uniform temperature increases comfort levels and helps
to eliminate cold spots.
• Single Point Electrical Hook-up: Heater, fan motor and
controls are all connected to the same branch circuit.
Standard Construction Features
Heating Elements – Industrial grade, Type 304 stainless steel
finned tubular elements, manufactured by HEATREX.
Housing – Heating elements and motor are enclosed in a
round, 16-gauge galvanized steel enclosure which has a powder coat finish for durability.
Inlet/Outlet Grilles – Inlet grille complies with OSHA requirements for fan blade guard. Outlet grille has 45° angled louvers
to direct airflow.
Fan Motor – Motor is UL Recognized with built-in
26
thermal protection.
Built-in Controls – Include main control magnetic contactor,
control voltage transformer, automatic reset thermal cutout and fan thermostat.

Fan Motor - Permanently lubricated and thermally
protected motor.
Built-in Controls - All units include an automatic
reset thermal cutout that will de-energize the heater
if an overtemperature condition occurs. A manual
reset thermal cutout, in addition to an automatic reset
thermal cutout, is standard on heaters 10 KW and
above. A fan relay is provided to allow the elements
to heat up before fan startup and purges the heater
of residual heat after shutdown. A 24-volt transformer
and disconnecting contactor are provided on most
heaters. Single-phase heaters rated at 5 KW or less
have line voltage controls; 24-volt control and contactor are available. Power fusing is standard on all heaters rated over 48 amps.
Mounting – Universal horizontal or vertical discharge.
Optional diffusers are available for vertical discharge.
An Anemostat diffuser can be used to provide draftfree air movement at lower mounting heights. For
higher mounting heights, radial diffuser with adjustable
fins can be used to increase floor coverage or adjusted for a vertical down blast of air.

motor with factory-lubricated ball bearings operates
at 58 dBA (2-10 KW), 67 dBA (15-30 KW) or 77 dBA
(40-60 KW). Blow-through design reduces motor operating temperature for longer life.
Built-in Controls – Include 240/208 volt control circuit (with transformer if necessary), automatic reset
thermal cutout, fan override and factory-installed
contactor. Power fusing is supplied for heaters over
48 amps.
Mounting Bracket – Wall and ceiling bracket provided with each unit under 40 KW for horizontal mounting. 40-60 KW heaters furnished with four corner
support brackets for ceiling mounting.
Installation Requirements – For best performance,
do not install unit heaters above recommended maximum mounting heights of 2-10 KW, 8-feet; 15-30
KW, 10-feet; 40-60 KW, 15-feet. All but 40-60 KW
heaters can be installed at lower mounting heights.

Architectural Wall Heater
F O R C E D - A I R
The 933 Series fan-forced wall heater is designed for
commercial and industrial areas requiring higher KW
ratings and quick recovery. The unit provides a burst
of heat in areas affected by cold drafts or wide temperature swings.
• Efficient Operation: The fan draws air into the top
of the grille and discharges warm air downward to
distribute heat and keep floors warm and dry. High
CFMs create air circulation within the room to provide uniform temperatures.
• E xtended Capacity: The 933 Series is available
with one or two modules and ratings up to 8,000 W
and 320 CFM.
Applications
•Entryways
•Restrooms

940 Series
The 940 Series wall heater is a unique design and offers two levels
of heating. The first level is convection heat with a second level
of forced-air heating. This feature combines the quiet operation of
convection heating for normal heating conditions and when needed
a boost to forced-air heating with greater heating capacity, all in the
same unit. This is well suited for condominiums when an up scale
appearance is required.
• Manual Power Boost: To override the automatic temperature
control the heater can be easily switched into the boost heat level
using the built-in timer. Boost power can be set for 5, 10, 15, 20,
25 or 30 minutes.
Applications
•Entryways
•Offices
• Fire Station Changing
Areas
• Reception Areas
H E A T E R S
• Unique Temperature Control: Built-in digital thermostat with full
modulating power for convection to fan-forced heating. The power
level is automatically managed by the thermostat through the full
output of the heater. The electronic thermostat displays actual
room temperature, with adjustable temperature settings between
50 and 95°F (10 to 35°C). When the heater is on, four graduated
lines indicate the power level on the display.

Applications
The 903 Series baseboard heater is more compact than any other
heater on the market, yet it provides a high level of performance
and strength. The unit’s trim design enhances its appearance and
rounded corners eliminate the sharp edges found on square heaters.
• E asy to Install: Heaters may be mounted flush on any floor surface. Two rows of oblong mounting holes with center mark for
ease of installation. No disassembly installation with single-screw
built-in rear entry wire holder.
• E lectric Receptacles: Units can be furnished with built-on 120 and
240-volt receptacles to provide access for other electrical appliances.
• C
ontrol Options: Heaters can be controlled by a building management system with the addition of a low voltage relay. Adding a
proportional control device provides precise temperature control
and increased energy savings.

Applications
• Air, Rail or Bus Terminals
•Hallways
•Auditoriums
•Lobbies
•Corridors
•Offices
•Entryways
•Foyers
The 904/906 Series architectural sill-height convector
(also known as draft barriers) are designed to fit under
large windows to prevent cold down drafts. These
heaters can provide total or supplemental heating for a
variety of applications.
• Installation Options: Units may be mounted to
the wall flush on the floor or on pedestals. Custom
lengths, blank sections and inside or outside corners
are available for wall-to-wall installations. Units can
be ordered with smooth painted finish when the back
of the heater is visible.
• Added Safety: The sloped-top of the 904 Series
prevents objects from being set on top of the heater,
which can restrict airflow and cause overheating.
• Choice of Colors: Heaters can be matched to any
décor. White or almond is standard and a wide range
of optional colors and custom finishes including anodized aluminum are available.
Standard Construction Features
Heating Elements – Stainless steel elements with
aluminum fins float on high temperature nylon bushings
for quiet operation.
Housing – Cabinet is constructed of 18-gauge steel
with a 14-gauge aluminum front cover. The unit has a
polyester powder paint finish in white or almond. End
caps are provided on all units.
Inlet/Outlet Grilles – The fresh air inlet grille is located
on the front of the unit. The outlet grille has openings
less than 0.25 inches to discourage tampering with the
heating element (pencil-proof).
72
Built-in Controls – Linear limit, automatic reset thermal cutout.
Electrical Connection – Each baseboard heater has
a junction box located on both ends and a built-in full
length wireway.
Installation Requirements – Field or factory-installed
low voltage relay and thermostat kits fit into the righthand junction box only.

Industrial Sill-Height Convector
Industrial Sloped Top Sill-Height Convector
The 905/907 Series industrial sill-height convector (also
known as draft barriers) are designed to fit under large windows to prevent cold down drafts. The heaters are ideal for
heavy traffic areas with high heating requirements.
• Installation Options: Units may be mounted to the wall
flush on the floor or on pedestals. Custom lengths and
blank sections and inside or outside corners are available
for wall-to-wall installations. Units can be ordered with
smooth painted finish when the back of the heater is visible.
• Length Options: Heaters can be installed singularly in
lengths from 20 inches to 103 inches or joined end to end
for complete perimeter heating.
• A
dded Safety: The sloped-top cabinet on the 905 Series
prevents objects from being set on top of the heater, which
can restrict airflow and cause overheating.
• Choice of Colors: Heaters can be matched to any décor.
White or almond is standard and a wide range of optional
colors and custom finishes are also available.
Standard Construction Features
Heating Elements – Stainless steel elements with
aluminum fins float on high temperature nylon bushings
for quiet operation.
Housing – Cabinet is constructed of 18-gauge steel
with a 16-gauge steel front cover. The unit has a polyester powder paint finish in white or almond. End caps
are provided on all units.
Inlet/Outlet Grilles – The fresh air inlet grille is located
on the front of the unit. The outlet grille has openings
less than 0.25 inches to discourage tampering with the
heating element (pencil-proof).
Built-in Controls – Linear limit, automatic reset thermal cutout.
Electrical Connection – Each baseboard heater has
a junction box located on both ends and a built-in full
length wireway.
Installation Requirements – Field or factory-installed
low voltage relay and thermostat kits fit into the righthand junction box only.

Radiant Ceiling Panels
Applications
•Atriums
•Lobbies
• Enclosed Walkways
•Offices
•Entryways
•Schools
•Hospitals
•Warehouses
AS Series radiant panels are ideal for offsetting heat
loss through exterior glass on the perimeter of a building. They help to control the problem of condensation
typically found with these large exterior glass walls.
Radiant panels provide improved comfort by maintaining an even temperature from floor to ceiling.
• R
adiant Heat: Radiant energy travels in straight
lines and is absorbed by objects in the room, warming the space. Air quality is maintained because no
forced air movement occurs with radiant heating.
• M
aximize Work Area: Ceiling mounted panels permit full use of floor and wall space.
• M
aintenance Free: Radiant panels have no moving
parts, so they are maintenance free and can provide
years of quiet, safe and clean operation.
Standard Construction
Features
Heating Element – High quality alloy resistance wire
is electrically insulated with a UL Listed TEFZEL®
compound rated for 200°C (392°F). Heating wires
are covered with high-efficiency reflective foil.
Panel Design – Panel is made of 22-gauge galva-
nized steel with a white baked-on powder paint finish.
Panel is crimped, not riveted, for improved strength.
Insulation – Each panel contains two inches of high
temperature/high density mineral wool insulation.
Electrical – A junction box is attached to each panel
for field wiring and to connect panels to each other.
92
Installation Requirements – Heater can be installed
in suspended T-bar ceiling systems or can be surface
or recessed mounted using optional mounting frames.
Heater comes equipped with four suspension clips.
Connecting wire or chain is supplied by customer.

Cove heaters are designed to supply efficient radiant
heat. They provide greater comfort at lower temperature settings and can be set up for individual or zone
control to reduce energy costs.
• Radiant Heat: Radiant energy travels in a straight
line from the heater to people and objects in the
room, warming the space.
• Convection Flow: The design of the heater provides
a convection flow from behind and over the top of the
unit to circulate warm air into the room.
• Virtually Maintenance Free: No moving parts to
replace or service.
• Exclusive Tilt and Lock Mounting System: Allows
easy, one-person installation.
