MONTREAL Branch Offices in Principal Cities Wing Featherweight Unit Heaters--Revolving Discharge Type The Nesbitt Syncretizer--Series 400 The last word in heating and ventilating units for schoolrooms, offices, etc., where the continuous introduction of outdoor air is desired. For engineering data, get Publication No. 225-1; for "The Story of Syncretized Air," Publication No. 231. Nesbitt Series B Thermovent For heating and ventilating auditoriums, gymnasiums, assembly halls, and similar gathering places. Publication No. 227-1. NESBITT COOLING SURFACE Series W (Water Surface with exclu sive drain featun For air cooling and cooling and dehumidifying (with cold water) or air heating (with hot water). Construct ed of copper tubes and plate-type alu minum fins. Avail able in either con tinuous or cleanable tube type, in single sections having one to eight rows of tubes deep, in three fin spacings, in eleven fin widths, and up to sixteen finned tube lengths. Sturdy galvanized casings. For particulars and engineering data send for Publication No. 233. NESBITT HEATING SURFACES Nesbitt Heating Surface with Dual Steam-distributing Tubes . Copper tube-and-fin surface for lowpressure applications. Perfectly adapted to close, continuous automatic control with modulating steam valves. Steam-dis tributing tubes within the condensing tubes carry the steam equally to the full section assuring UNIFORM discharge temperatures even under a throttled steam supply; eliminating temperature strati fication; preventing tube freezing without preheaters; giving ideal system results. Cased or uncased units of many sizes and capacities. Sold (like all other Nesbitt Surface) by leading manufacturers of fansystem apparatus (list upon request). For full particulars and engineering data, send for Publication No. 229-1. Nesbitt Series H Heating Surface A lightweight, enduring, highly efficient blast-coil heating surface designed for use with steam pressures up to 200 lb gauge. Well suited to high-pressure as well as lowpressure applications. Seven types, each in eight fin widths and up to sixteen finned lengths--a total of 784 sizes from which to select. Sold by leading manufacturers of fan-system apparatus (list upon request). Send for Publication No. 232 for complete engineering data. 854 This innovation in the method of dis tributing heat produces a sensation in heating comfort never before attained--a sensation of fresh, live, invigorating air. The fact that the outlets revolve assures uniform and thorough distribution of com fortably warmed air throughout the entire working area, without drafts, hot spots or cold spots. The latest type of WING Unit Heater-- with Revolving Discharge Outlets--is just as great a contribution to the art of industrial heating as was the Ceiling-Suspended Unit Heater, origi nated by WING in 1921. Such an unprecedented high efficiency in distributing heat is the result of nearly 20 years of constant study by Wing engi neers to improve on the Floodlight System of heating originated by WING in 1920. This method projects the heated air verti cally downward by means of light-weight, ceiling-suspended unit heaters. It has needed only this latest refinement of slowly revolving discharge outlets to bring that method to perfection. The WING Revolving Discharge type supplements the WING line of standard fixed discharge outlets, illustrated and described on the following page.
