204 ASHRAE Guide And Data Book IIMI=RyAVI-UX GAS INFRA-RED COMFORT HEATERS The C. A. Olsen Manufacturing Company Elyria, Ohio THE INFRA-LUX GAS INFRA-RED HEATER... a totally new, ruggedly built, all metal unit of proven design The Infra-Lux Gas Infra-Red Heater sets a new standard for performance and durability. It is based on a design proved in thousands of successful applications in the United States and Canada... is exclusively available in the United States from the C. A. Olsen Manufacturing Company. Olsen's modem manufacturing and testing facilities plus experienced engineers who have "lived" with gas infra-red hearing from its very beginning assure you of unmatched performance and application economy. 1. laceael Alley Screes Assembly aad Grid Sereen: Constructed wrih three layers of high temperatureresistant. fine-mesh Inconel Alloy Screen -- heatresistant to 2100*F. Maintains combustion on surface of outer screen at 1550T. with 1/32" flame. Heavy-mesh grid screen, located 1/4" from com bustion surface boosts radiation temperature to 1650*F... the optimum temperature for radiant heating efficiency. 2 Reflector Shade Assembly: Constructed of polished aluminum. Directs infra-red rays to pro duce uniform,constant coverage of a pre-determined area. Straight-sided reflectors produce "spread" dispersal pattern, are used for lower mounting heights. Parabolic reflectors produce more concentre**! pattern; are used for higher mounting heights or where greater teat concentration h required* 8. Frame Assembly: Constructed of heat resistant stainless steel; supports burner casting. 4. Dads: Provide direct, positive exhausting of combustion by-products. 5 Moeotieg Brackets: Provide easy suspension either horizontally or up to 30 degree angle. 6 Asbestes Gasket: Seals and insulates burner housing from frame assembly. 7 Burner Casting: Improved venturi design pro vides most efficient mixing of combustible gas-air mixture. Evenly distributes mixture across burner screen assembly to assure uniform temperature. Fins dissipate heat to help assure optimum com bustion. 8 Berner Shield Assembly: Protects venturi air inlet from drafts and foreign objects. 9 PDot Assembly: Assures safe lighting; thermo couple lead shuts off unit in case of gas failure. Pilot is completely shielded to eliminate blow-out and clogging; located out of range of intense radi ant heat; available with automatic electric or manaal ignition. - 10 Centre! Assembly: All electric and gas con trols located outside high temperature heat zone to assure dependable performance. 11 Main Miaul Gas Valve: Shuts off gas supply to individual heater to permit safe inspection while rest of system continues to operate. 12 Gas Pressure Beguiiler: Provides precise regulation of gas pressure at individual heater. 2K Catalog Data Section 205 THE ALL-METAL INFRA-LUX BURNER ...key to Infra-Lux Efficiency and Durability f y bori*er is be "hewT oI ill lofre-ln Gas iRfrtHesters.
