Webster System Radiation was first offered in 1932. Now, available in an improved design, using the same basic material, copper tubing and aluminum fins. Increased rigidity of the tubing and the development of a new method of manufacturing has produced a fin surface of unusual rigidity, free of expansion and contraction noises. Ask for Bullp tin B-1500. Webster Walvector--Elongated,, nonferrous convector. Heating element is made up of a specially annealed cop per tubing with rib-reinforced, square pressed aluminum fins. Available in two fin sizes: 3 in. fin size in 2, 3, 4, 5 and 6 ft; 4 in. fin size in 2, 4, 6 and 8 ft lengths. Boiler Protectors--One size, with % in. connections with or without electrical cut-out switch. Maximum pressure 15 lbs per sq in. Maximum cold water main pressure, 150 lbs per sq in., minimum not less than 25 lbs per sq in. Prevents breakage in low pressure heating boilers when the water level becomes inadequate.

Nesbitt, Inc., Philadelphia 36, Pa., and are distributed solely through Warren Webster & Company, Camden, New Jersey. Designed to circulate large volumes of air at comparatively low temperatures, assuring quick heating. Ratings of Webster-Nesbitt Unit Heaters are based on tests made in accordance with standard test code of Industrial Unit Heater Association and A.S.H.V.E. PROPELLER FAN UNIT HEATERS Designed to in corporate four characteristics essential to * |1 ill iL,, both proper application and satisfactory HniijmiirimifLiii, H H I ri t O H performance: 1.) Selective range of. sizes. Manufactured in nine sizes. Heating capaci Fig. /. Standard Propeller-Fan Type. ties vary from 34,700 to 338,000 Btu per hour. Air deliveries from 470 to 4800 cfm. 2.) Quiet Operation. All fans have blades of exceptionally large areas and of a shape to impart a gradual accel eration to the air stream. Ample spacing is maintained between the fan and heat ing element. Motors are of sleeve bear ing type and equipped with isolators. 3.) Durable lightweight Heating Elements. Extended fin-and-tube type, constructed of copper condensing tubes and plate- type aluminum fins. 4.) Modem Casing Design. Compact suspended type. W-N 126. GIANT UNIT HEATERS Sturdy blower-fan units for the econom ical heating of large areas. Standard (NonThermadjust) type. Used principally where heating is by recirculation only, and where constant heat output is desired during period of operation. Fig.s. Blower-FanType Thermadjust Type Employs dampers in front of casing and over face of heating element to provide mixing of unheated and heated air, pro ducing heat output in accordance with requirements and continuous circulation of air volume. Valve Controlled Type. Unit is of standard casing arrangement but equipped with Nesbitt Heating Surface and Steam-distributing Tubes which allows for automatic control of heat output. Floor mounted, wall mounted, ceiling suspended, from 101,000 Btu, 2580 cfm, to 1,008,000 Btu, 17,800 cfm. Pub.W-Nl28. . SERIES "R" UNIT HEATERS A neat, furniture steel cabinet enclos ing a copper tube, aluminum fin heating element adaptable for steam or forced hot water systems; and two to five centrifugal fans belt-driven from an elec tric motor. ' Universal design offering wide flexibility. Especially adaptable where low noise levels are desirable. Variable-pitched motor sheave permits low or high speed operation of fans. Available in four sizes. Air deliveries with standard drive range from 518 to 1890 cfm. Steam heating capacities range from 158` to 588 EDR. Send for Catalog W-N 133. Pig. t. Series URU UniCHeater.

The three smaller sizes are of the blow-through type, having lower out let velocities generally intended for the lower mounting heights of commercial installations. These sizes are made in down-blow type only. The four larger models are of tne draw-through type, and produce the high discharge velocities necessary to blow long distances. These four models are available in either hori zontal or vertical down-blow arrange ments. Non-ferrous all-purpose heating ele ments designed for steam pressure up to 200 lb gauge, saturated, and sturdy cas ings of modern design. Heating capaci ties range from 28,500 to 348,000 Btu, basic steam ratings. Send for publica tion W-N 134. 1407
