Radiation (Concealed Gravity Typ^ Heintz Manufacturing Company i Front Street and Olney Avenue Philadelphia p MANUFACTURERS OF CABINET AND CONCEALED RADIATORS ^ The Heintz Radiator Unit is built of tubing, fins and headers. No part of the core is less than Y& in. thick. The end headers are drop forgings having integral ferrules. The core is welded together by means of the recently developed "atomic hydrogen" process which gives.the most homogeneous and ductile weld so far produced. The fins are applied by hydraulic pres sure and the whole unit is then hot gal vanized inside and out. The Heintz Radiators, while much lighter than cast iron radiators, are very sturdy, and with ordinary care, the danger of becoming damaged during in stallation is remote. The tappings at the ends are 1Y in., permitting them to be connected exactly the same as is customary with cast iron. No trick piping is required. Every radiator is tested for leaks before shipment. The ratings of radiators shown are con servative condensation ratings. . It ;j deemed advisable to continue to rate Heintz Radiators on this basis until such time as an acceptable method of tebtinc and rating has been determined upon which will include heating effect. \ Roughing-in Diagram of Standard Cabinet Radiator Lengths--in Inches Lengths--in Inches 69^--81K--93>i--105^--117K- Drawing at right . ehowt ' Tcmghing-in - dimensiont of the Doable Cabinet Radiator |-------------68------- 80--92------- 104-------116--------------- 1 Ratings in Sq.

Concealed Radiators, Cabinet Radiators and Wall Radiators of the Finned Type ' International Radiators are convector ` concealed radiators made of durable JSterials. They occupy far less space than \Jmarv heating equipment, cost less to ^tall'and give efficient results with hot ter steam, vacuum and vapor systems. CONSTRUCTION: --International Radiators have only three parts--mal leable headers, copper tubes and iron fins. Fins are stamped channel shaped from 025-in rust-resisting sheet iron. They are forced, under high pressure, over pure seamless heavy gauge copper tubes. Two-pipe Steam or Hot Water International Radiator The copper tubes are then welded into malleable iron headers. Malleable iron is used because its high tensile strength prevents breakage. After the tubes have been welded in, each end of the radiator is hot galvanized , inside and out. Galvanizing prevents rust . and keeps the inside of the radiators clean. / DESIGN: -- International Radiators emphasize the practicability of clean cut \ design. Tubes have been shaped to present minimum air friction and still have a large internal volume. The internal volume of the 3-in. radiator is 20 per cent greater than a lj^-in. pipe, and the volume of the ,, 5 and 7-in. radiator is greater than a 2 J<j-in. pipe.. Resistance to flow of water in these radiators is minimum. Fins are 8-in. high, so that air is in con (act with the fins through a greater time interval and consequently can absorb more heat, making these radiators especially ' effective on hot water installations. TYPES:--International Radiators are i made in 3, 5 and 7-in. depths; and in 8 ; lengths, from 18 to 60 in., by 6-in. intervals. _. Thev are made in two types; leg and wall- hung. Wall radiators are furnished with brackets. Two-pipe radiators can be used on vapor, vacuum, gravity steam and hot water. One-pipe radiators can be used on one-pipe pressure or vapor vacuum systems. INSTALLATION:--All connections are equally distant- from floor level and International Radiators are reversible, making roughing-in and installation easy and simple. Pipe connections are always on center of the radiator and the supply can be installed at either end. Wall radiators have top and bottom connec tions, which puts the valve high enough for convenience. ENCLOSURES:--The International Radiator Corporation carry in stock three standard types of enclosures, the Recess Enclosure, Free Standing Cabinet and' the Wall Cabinet. The Recess Enclosure is telescopic, the adjustment range being from 20-to 30 in: in height. This is a novel and very important feature, as it simplifies ordering, handling and installation.. Re cess Enclosures are complete with a bar type outlet grille and damper, and a re movable plate at the bottom for accessi bility to radiator valve and trap when necessary. ;. Enclosure for International Concealed Radiator GUARANTEE:--Every product bear ing the "International" name is guar anteed to be free from defects in material and workmanship, and radiators found to be defective will be replaced f.o.b. factory. SPECIFICATIONS AND LITERA TURE:--Write for Catalog 30-G con taining specifications, ratings, installation and other useful engineering data. 779 -j
