IntroductionHazardous 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 atmo-sphere. Hazardous locations are created from the normal pro-cessing 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 restric-tions: 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 caparable remote oil or gas fired heating systems.

National Electrical Code ClassificationArticles 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 alter-nate class and zone classification.

ClassHazardous 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, petro-chemical 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 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 han-dling of pulverized sugar and processing and storage of mag-nesium 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, wood-working plants, cotton gins, cotton seed mills and flax produc-ing plants.

DivisionClass I, Class II and Class III areas are further defined in terms of when the hazard occurs. Division 1 and Division 2 occur-rences are summarized below.

Division 1 – If the hazard is expected to be present under normal conditions, such as a production or processing facil-ity, the occurrence is designated Division 1. The hazardous atmosphere may be present continuously, intermittently, peri-odically, or during normal repair or maintenance operations. Division 1 occurrences also include locations where a break-down 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.

Use of Electric HeatersIn Hazardous Locations

GroupThe nature and explosive characteristics of the hazardous materi-al 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 alumi-num 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 and Zone ClassificationsClass I, Zone 0 – Locations in which ignitable concentrations of flam-mable gases or vapors are present continuously or for long periods.

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 flam-mable gases or vapors are not likely to occur under normal opera-tion, exist only for a short period or exist only as a result of acciden-tal 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 GroupsGroup 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.

Group IIB – Atmospheres containing acetaldehyde. Equivalent to Class I, Group C as described in NEC Article 500.

Group IIA – Atmospheres containing acetone, ammonia, ethyl alco-hol, gasoline, methane or propane. Equivalent to Class I, Group D as described in NEC Article 500. Ignition Temperature

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.

Product use depends on temperature class. The temperature code indicates the maximum temperature of the exposed surface of the product. For Zone classified dusts the explosion-proof temperature is the maximum surface temperature is shown as e.g. T800C

Electric heating equipment can be economically designed and safely used in hazardous areas if the following special require-ments 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 select-ed, 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.

2. All arc and spark-producing control devices must be isolated from the hazardous atmosphere. If it is not economically fea-sible to locate the control devices in the non-hazardous area, they must be housed in an enclosure that will withstand the pressure of a potential explosion from within the enclosure.

3. All electrical supply connections must be made according to the latest NEC and local code requirements for hazardous loca-tions. This includes the requirement that conduit entering the enclosures must be provided with seals at the enclosure.

Heatrex’s 236 Series explosion-proof unit heater is designed with both size and economy in mind.

• Compact Size: This small design is only 13 inches wide, which makes it ideal for applications where limited space is avail-able.

• 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 explosion-proof con-vection heaters.

• Redundant Overtemperature Protection: Primary and secondary automatic reset thermal cutouts for additional safety.

• Stainless Steel Construction: Provides superior corrosion resistant protection. Optional Dirty Duty construction adds polyester powder coating to all aluminum parts for use in corrosive applications.


Applications• Chemical Storage/ Handling

Areas

• Compressor Stations

• Marine and Offshore

• Oil Platforms and Refineries

• Sewage/Wastewater Treatment Plants

• Spray Booths

Standard Construction FeaturesHeating 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 stan-dard 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 heat-ing elements after they have been de-energized.

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.

The Heatrex 234 Series unit heater is the perfect solution to the problem of heating people or equipment in non-hazardous environments where moisture and corrosion exist. Advantages of the 234 Series include:

• 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 con-trols are all connected to the same branch circuit.

• Corrosion Resistant: Stainless steel construction, powder- coated 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 finish-ing plants, cement, sand, grain and food processing facilities.

Applications• Car Washes

• Cement Plants

• Coal Handling Areas

• Dairies

• Food Processing Plants

Standard Construction FeaturesHeating Elements – Industrial grade, Type 316 stainless steel tubular elements with stainless steel fins, manufactured by Heatrex.

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 powder- coated, aluminum fan blade suitable for corrosive salt spray environments.

Housing – Heating elements and motor are enclosed in a round, heavy 16-gauge 304 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, 304 stainless steel rear grille protects against accidental contact with the fan blade.

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.

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).

Mounting Bracket – The heater comes complete with a 304 stainless steel swivel mounting bracket which can be used either for wall or ceiling mounting. Four field-supplied 3/8-16 threaded rods can also be used for ceiling installation.

The 926 Series unit heater is designed for industrial and commercial applications.

• Large Capacity: Heavy-duty construction with ratings up to 60 KW at 2,000 CFM.

• Control Options: Wide range of factory built-in or field- installed control options to meet job specifications.

• Single Point Electrical Hook-up: Heater, fan motor and controls are all connected to the same branch circuit. Field connections and built-in controls are easily accessed in the side-mounted control compartment.

• Discharge Direction: The UCI heater may be mounted hor-izontally using one of two brackets (supplied) or vertically using four threaded rods (not included).

Applications

• Garages


• Stairwells

• Vestibules

• Warehouses

• Workshops

Standard Construction FeaturesHeating Elements – Industrial grade stainless steel tubular elements in 2-10 KW units and steel finned tubular elements in 15-60 KW units.

Housing – Cabinet is constructed of 18 and 20-gauge galva-nized steel finished with durable almond polyester powder paint.

Outlet Grille – The outlet grille has individually adjustable louvers to direct airflow. A protective outlet mesh screen, provided on 2-30 KW heaters, allows for lower mounting heights.

Fan Motor – Totally enclosed, thermally protected motor with factory-lubricated ball bearings (except for 15 to 25 kW at 208/240V) 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 sup-plied 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 ceil-ing 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. Minimum height for 40-60 KW heaters is 8-feet. Maximum ambient room temperature for proper operation is 85°F. These units are not for residential use in the United States.

940 SeriesHybrid Convection Wall Heater

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 con-dominiums when an up scale appearance is required.• Unique Temperature Control: Built-in digital thermostat with full mod-

ulating 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.

• 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.

• Mounting: The heater can be recessed in a 2-inch by 3-inch stud wall, or surface mounted with or without a color matched surface mounting box.

Standard Construction FeaturesHeating Elements – Instant heat nickel-chrome coil resistant wire element.

Outlet Grille – Heavy cast aluminum front cover with steel bar inlet and outlet grilles has a polyester powder paint finish available in white or almond.

Built-in Controls – Digital display electronic thermostat with timer, automatic reset thermal cutout, overtemperature warning light, temperature sensor and LED night light with on-off switch.

Fan motor – Whisper-quiet squirrel-cage fan with factory-lubricat-ed motor.

Installation Requirements – Maintain a minimum of 4-inches (102 mm) clearance below heater, 1-inch (25 mm) to adjacent walls and 48-inches (1219 mm) in front of heater.Rough In Dimensions – All heaters: 18-3/8” wide x 13-5/8” high x 2-3/4” deep.

AS SeriesRadiant Ceiling Panels

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 pro-vide improved comfort by maintaining an even temperature from floor to ceiling.• Radiant 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.

• Maximize Work Area: Ceiling mounted panels permit full use of floor and wall space.

• Maintenance Free: Radiant panels have no moving parts, so they are maintenance free and can provide years of quiet, safe and clean operation.

Applications• Atriums

• Enclosed Walkways

• Entryways

• Hospitals

• Lobbies

• Offices

• Schools

• Warehouses

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.• Easy 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.

• Electric Receptacles: Units can be furnished with built-on 120 and 240-volt receptacles to provide access for other electrical appliances.

• Control Options: Heaters can be controlled by a building manage-ment system with the addition of a low voltage relay. Adding a pro-portional control device provides precise temperature control and increased energy savings.

Applications• Offices

• Retail Stores

• Restrooms

• Restaurants

Standard Construction FeaturesHeating Elements – Stainless steel elements with aluminum fins float on high temperature nylon bushings for quiet operation.

Housing – Robust 22-gauge steel body with 20-gauge front panel and welded junction box, with 4H pencil hardness epoxy/polyester powder paint finish in white or almond.

904 The 906/904 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 installa-tions. Units can be ordered with Option “S” for smooth painted finish when the back of the heater is visible.

• Added Safety: The sloped-top of the BCSI 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.

Applications• Air, Rail or Bus Terminals

• Auditoriums

• Corridors

• Entryways

• Foyers

• Hallways

• Lobbies

• Offices

Standard Construction FeaturesHeating Elements – Stainless steel elements with aluminum fins float on high temperature nylon bushings for quiet oper-ation.

Housing – Cabinet is constructed of 18-gauge steel with a 14-gauge aluminum front cover. The unit has an epoxy/poly-ester 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 cut-out.

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 right-hand junc-tion box only. Heaters 200 watt/ft or greater are not designed for residential use in the United States.

907/905 SeriesIndustrial Sill-Height Convector

Industrial Sloped Top Sill-Height Convector

907

905 The 907/905 industrial sill-height convector (also known as draft bar-riers) 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 Option “S” with smooth painted finish when the back of the heater is visible.

• Length Options: Heaters can be installed singularly in lengths from 28.8 inches to 103.4 inches or joined end to end for complete perimeter heating.

• Added Safety: The sloped-top cabinet on the 905 Series pre-vents 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.

Applications• Air, Rail or Bus Terminals

• Auditoriums

• Corridors

• Entryways

• Foyers

• Hallways

• Lobbies

• Offices


Housing – Cabinet is constructed of 18-gauge steel with a 16-gauge steel front cover. The unit has an epoxy/polyester powder paint finish in white or almond. End caps are provid-ed 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).


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 right-hand junction box only. Heaters 200 watt/ft or greater are not designed for residential use in the United States.

908

The 909/908 Series architectural convectors are designed to heat large commercial spaces without the fan noise associ-ated with unit heaters.• Installation Options: Units may be mounted to the wall,

flush on the floor or on pedestals. Custom lengths, blank sections, sub-bases and inside or outside corners are available for wall-to-wall installations. Units and accesso-ries can be ordered with smooth painted finish when the back of the heater is visible.

• Added Safety: The sloped-top cabinet on the 908 Series prevents objects from being set on top of the heater, which can restrict airflow and cause overheating.

• Recessed Mounting: The 909 Series heater can be fully recessed when the front warm air outlet option is used.

• 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.Applications

911

The 912/911 convectors are designed to heat large com-mercial spaces. They provide large amounts of heat without the fan noise associated with unit heaters.• Installation Options: Units may be mounted to the wall,

flush on the floor or on pedestals. 912 Series units can be fully recessed when the front warm air outlet option is used. These units are not for residential use in the United States.

• Added Safety: The sloped-top cabinet on the 911 Series prevents objects from being set on top of the heater, which can restrict airflow and cause overheating.

• Wall-to-Wall Installation: A smooth painted finish back plate is available so that the unit can be mounted against glass walls.


• Conference Rooms

Standard Construction FeaturesHeating Elements – Stainless steel elements with aluminum fins float on high temperature nylon bushings for quiet opera-tion.

Housing – Cabinet is constructed of 20-gauge steel with a 16-gauge steel front cover. The unit has an epoxy/polyester powder paint finish in white or almond. Mounting holes are provided along the back of the cabinet for wall installation.

Inlet/Outlet Grilles – The fresh air inlet grille is located on the front of the unit. An extruded aluminum outlet grille discour-ages tampering with the heating elements.
