H__eating Sn yst.ems Stokers and Draft Fans .y= The Whitty Company, Inc. 86 Western Avenue -- Boston 34, Mass. INDUCED AND FORCED DRAFT FANS COAL CONVEYORS AND STOKERS INDUCED DRAFT FANS Used in lieu of tall chimneys; used to improve the combus tion efficiency of automatic burners; used to correct inadequate draFfut.rnished in 20 models with capacities to 24,000,000 Btu boiler output. A size to match every boiler and heater in the Commercial-Industrial range. Fan housing is mounted on a rigid structural chassis in either a clockwise or counter-clockwise rotation; with a choice of vertical, horizontal, or angular discharge. See "Time-Saver" chart below for application data. DRAFT MONITOR Prevents start-up of burner unless boiler draft is proved adequate and cuts off burner whenever the draft becomes inadequate. Specify DM-3. STEAM DRIVE Steam-turbine Drive has built-in speed reducer to maintain the same slow speed feature as the motor-driven models. Add Suffix "S" to model number. Steam Drive MECHANICAL TURNDOWN Turning handwheel varies Fan speed through an automatic pulley device while maintaining constant motor speed. Add Suffix "J" to model number. MULTI-BLADE DAMPERS Inlet boxes with factory installed Dampers are available for use with power-operated draft regulators. Add Suffix "L" to model number.

S. Radiator Corporation Sales and Executive Offices Oswego, New York Factory Distributors throughout the United States CYCLOTHERM STEAM AND HOT WATER GENERATORS ... operate on Cyclonic Combustion prin ciple. Completely automatic with full safety controls. Oil, gas or interchange able gas and oil firing. Only four con nections required. The Cyclonic Combustion operating principle causes the fuel to be burned while spiraling at high velocity around the inside wall of the combustion chamber, forming virtually a tube of flame. This provides uniform and highly efficient heat transfer over the entire furnace wall without hot spots. Com plete utilization of heat transfer areas provides quick heat as well as greater than 80 percent efficiency with the re duced maintenance of a two-pass design. 15 to 80 hp models are equipped with `on-off" control; 100 to 750 hp models have modulated control. 80 hp units -with modulating controls furnished at customers' request. Automatic combus tion safeguard, low water and other safety controls are included. Pressure Range Available in standard low pressure units or high pressures up to 200 psi. Hot water generators are also available in all sizes.
