L. J. Wing Mfg. Co. Air System Equipment Unit Heaters WING FEATHERWEIGHT UNIT HEATERS Floodlights of Heat for Economical Heating of Industrial and Commercial Buildings Low heating cost and uniform diffusion of comfortable warmth are two features in which WING Floodlight Heating excels all other systems. Located near the ceiling or roof, WING heaters prevent accumulation of hot air in the upper spaces with the accom panying costly waste of heat. They project the air, comfortably warmed, to the working area where the heat spreads to every point. Vertical downward discharge from multiple outlets at proper velocity assures "Stationary Discharge" Unit Heater even distribution. The lightness of WING units permits their suspension directly overhead in any location. Furthermore, one WING unit heater with multiple discharge takes the place of several one-direction heaters at less cost for units, piping, wiring and installation. There is a type for every condition from low ceiling to installations as high as 55 ft. from the floor. Type HC heaters should be used wherever roof or ceiling height permits. Type LC has the same capacity as Type HC and is designed for low buildings. Bulletin H-8. Wing Featherfin Heater Sections For heating or cooling air for any purpose by steam, hot water, cold water or refrigerant. Offer slight resistance to air flow. Variable Temperatari Heating Section, . Variable Temperature Sections Allow close control of the delivered air tem perature without danger of freezing which is likely when control is accomplished by throttling of steam. Invaluable in supplying fresh air for space heating or in process work. Bulletin HS-1. Detail of Wing Featherfin Heating Element showing Compression Union Tube Connection Wing Garage Heaters--For effective and economical heating of garages. Some times cut heating costs in halt. Bulletin G-l. Wing Door Heaters--For instan taneously heating inrush of cold air at large doorways of industrial buildings. Bulletin D-l. Wing Utility Unit Heaters A lightweight suspended unit heater for delivering heated air in one general direction. Has the same powerful fan and rugged aflSflB' heating element as WING Featherweight Unit Heat ers. This is the latest re finement of the original horizontal light weight heater which was developed by WING. Bulletin U-4C. Wing Industrial Fog Eliminators Eliminate fog, odor and fumes in dyeing, bleaching and finish ing plants, creamer ies, pasteurizing, bot tling, canning and packing plants, chem ical works, paper mills, steel pickling plants, etc. No ducts are required. Bulletin FE-12. 856 L. J. Wing Mfg. Co. Air System Equipment Fans and Blowers Wing-Scruplex Safety Ventilating Fans A propeller type fan that will deliver air against static pressure, quietly and efficiently. Moves the air forward in straight lines with minimum eddy. Capacities to 100,000 cfm. Bul letin F-8. Wing Featherfin Process Heating Units For man ufactur ing pro cesses such as drying, aging, etc., re quiring the recirculation of the heated aii Motor or turbine located outside air cur rent. Bulletin P-2. Wing-Scruplex Exhausters For economically moving air wherever ducts are used. It combines the efficient WINGScruplex Propeller Fan with a housing which places the motor entirely outside the air duct. Motor and drive remain cool and clean and are easily accessible. The powerful WING-Scruplex Fan delivers high air volume with low. power consumption against any pressures for which duct systems should be designed. V-belt ordirect drive. Light, compact and easy to install. Bulletin 78-A. WING System of Controlled Combustion For low pressure heating boilers and small power boilers. Increases capacity and permits use of lowest cost fuel. Includes Type EM Blower equipped with fully enclosed dustproof motor with speed regulating rheostat and automatic control. Eliminates necessity of frequent firing, allowing intervals as great as 24 hours even in zero weather. Bulletin M-86.
