Complete line of ELECTRIC HEATING SYSTEMS for HOME-INDUSTRY-FARM ROCHESTER 3, NEW YORK you aeed advice in any field, you consult a specialist Decid- ' con beating sysem is an important matter--one that you do oot JjjLrtgke very often. Therefore, it is only natural and in the course , ypdom, that you will look to a specialist in this field. For more 30 years Electromode has devoted its research engineering ggd manufacturing facilities predominantly to the design and pro* jggjoo of electric space heating equipment and is one of the oldest in the business. The Safety Crid Heating Element is an Electro mode feature. All electric wires are insulated, embedded and com pletely sealed inside a finned atuminnm casting. No exposed hot wires, no glowing coils and no danger of fire, shock, or bum. This finned aluminum easting spreads the heat rapidly, resulting in higher efficiency and greater economy. The built-in safety switch automatically prevents overheating. The Safety Grid Heating Ele ment is guaranteed for 5 years against any defect in material or workmanship. For HOME and OFFICE- Fig- I Fig. 2 WALL-TYPE HEATERS Bectrooode Wail-type Heaters are made in models and capacities suitable for *U size moms, ranging from 1320 to 4000 watts, viffi built-in thermostat or manual control. Heat is fan-circulated at floor level. All have (utomatic thermal safety switch. The big room hesters have silver grey finish and can be painted to match decor. The small room cr bathroom heaters are available in gleam ing chrome or white enamel and are used as complete or auxiliary source of heat. See figs. 1 and 2. Tig. 3 Low-LEVEL BASEBOARD HEATERS Classically slim Low-LEVEL fits snugly to wall leaving more usable floor space. Spreads radiant warmth over cold walls without drafts and thermostatically con trolled by room thermoslat- Customized fit tings impart pleasing, flowing appearance completely flexible to room and design. Rugged steel cabinets, finished in golden bronze, can be made to blend with wall tones, if desired- Capacities from 550 to 22>0 watts, 120, 240 and 208 volts. Easy to install. Only two assembly screws per unit. Snap-on front paneL No separate end caps. Easy access to wireway. See fig. 3. Fig. 4 Fig. 5 FLOOR INSERT HEATERS Mount flush with floor, causing no obstruc tion in front of windows or in passageways. Install in wood or concrete. See fig. 4. RADIANT CABLE HEAT Coils of cable hidden in ceiling radiate clean heat downward. Each room tempera ture controlled by separate thermostat. Cables are a measured length of special in sulated electric wires; waterproof; noncorrosive. Used in plaster, drywafl ceilings, or concrete floors. Magic Seal coating pre vents streaks on ceiling. See fig. 5. For INDUSTRY Unit Hesters available in Suspension-type tad Combination Portable and Suspension "odeljL Capacities from 1500 to 45,000 vitts. Fine for auxiliary warmth in bard- ta-beat areas and for complete beating in outlying buildings. Adjustable louvers for directing fan-circulated heat into working *oe. Thermostat control available on all Models. See fig. 6 for Suspension and ng. 7 for Portable and Suspension. The Nectrwnode Commercial and Industrial beater is specifically designed for quick, 'wufortable, warmth in factory depait*uta, offices, supermarkets and other areas *b^re its quiet operation is an asset. It is t*aly portable, or it may be mounted ou *wivel-type brackets. 5KW-240 volts--single 3 phase--17,075 Btu. See fig. 8. Explosion-Proof heaters are specially en gineered for installation in hazardous areas where heat is required and danger of explo sion exists. They conform to rigid safety specifications and are fully tested and ap proved by Underwriters' Laboratories for use in areas covered in Class 1- Group D hazardous locations. Used in places where atmospheres contain gasoline, petroleum, naphtha, solvent vapors, natural gas and where flammable gases etc. are made oi stored. Convection type. Three-models range from 2000 to 6000 watts. See fig. 9. BLAST COILS Consists oi a bank of Electromode castaluminum heating elements mounted in a 16 gauge formed steel frame having a IVs Fig. 10 Kg. 11 in. wide flange with 5/16 in. holes on ap proximately 6 in. centers for mounting to air ducts. Complete wiring diagrams for special applications furnished on request. See fig. 10. Electromode Insert Duct Heater (fig. 11) Safety and endurance is inherent in its con struction. It was designed as a package unit ready for easy installation. The Safety-Grid heating element is your assurance of com plete protection against fire, shock or burn. Safety switch automatically breaks the serv ice to the heater in the event of stoppage of air flow through the heater from any cause. It is an automatic reset type. Engineering help gladly given.
