Air System Equipment Cons I^ KRITZER RADIANT COILS, INC. "IF IT'S KRITZER, IT'S RIGHT SIR" 2909A LAWRENCE AVENUE * -CHICAGO 25, ILLINOIS KRITZER "FIN-TUBE" RADIANT COILS Kritzer "FIN-TUBE" Radiant Coils introduce a new, im proved method of radiant heating. They are enclosed in joist or stud spaces, concealed but not imbedded in structural ma terials. They warm the air in these spaces, and indirectly warm ceilings, floors or walls to produce radiant panels for all areas. No concentration of heat in one spot. Kritzer com bines low first cost with lower installation costs. Installation begun and finished when framing is up, and before plastering. Coils are installed crosswise to joists--finned sections lying be tween joists slightly above plaster; tubing suspended on hang ers with metal clad insulating sleeves. Simple construction. A single % in. copper tube is mechanically bonded to 134 in. x 3 in. aluminum fins, in sections for highly multiplied heat transfer surface. i. , i These compact, attractive baseboards supply heat both by ra diation and convection--allow maximum use of floor space-- harmonize with any interior decoration. Standard Baseboard Coils are made with aluminum fins 2 in. x 534 in. mechanically bonded to two 34 in. copper tubes. Universal Coils are made with 2J4 in. x 3% in. fins in steel, aluminum or copper on 1 in. or. 134 in. diameter steel pipe or copper tubing. Installation re quires only three quick, easy steps. (1) Steel back plate is placed against wall on finished floor and fastened. (2) Elements are then snapped into place. (3) Front cover is simply snapped in place and end enclosures installed where required. Damper with control knob is available as optional equipment. Furnished in standard 10 ft, sections easily cut on the job, or cut to length on order. KRITZER "FIN-PIPE" COMMERCIAL HEATING COILS More Btu's for less time, labor and dollars! Engineered for greater efficiency and faster installation. Kritzer "FIN-PIPE" Coil sections easily equal the heat output of equipment costing over twice as much, yet Kritzer Radia tion more than cuts in half the time and labor necessary for installation. Fins grip pipe with specially designed deep col lars to assure better heat transfer and a permanent, positive mechanical grip. Pipe sections are furnished with chamfered ends, ready for welding, or threaded with modern, improved chaser type die heads that give clean, sharp threads so necessary for fast, leak-proof connections. A vari ety of covers snap on to wall hangers but do not touch fins.
