LOUIS TULSA WASHINGTON CENTRIFUGAL PUMPS The is a compact, "pack age" unit, mounted integrally with motor on a rigid, oversize shaft and over-size bearings. It is highly adaptable to many services, needs no special foundations, and operates equally well in any position, it is available in several materials for pump ing various liquids. Capacities from 10 to 1800 gpm, heads to 600 ft. Other I-R pumps are offered for all hy draulic services, with any type of drive. ALL PURPOSE PORTABLE TOOLS Electric Impactools are light-weight portable, tools for running and removing nuts, screws and studs, drilling, reaming, tapping, wire brushing, drilling brict and masonry, driving wood augers, holesaw work, and the 101 jobs encountered in installation work. Plug into any walloutlet. Capacities: % in. drills, tapping to % in., running nuts to % in. thread size. 110 or 220 volts, universal motor. LIGHT-WEIGHT JACKHAMER The J-10 Jackhamer is the smallest of the self-rotating, rock-drill line, weighs 14 lbs, and is especially designed for mainte nance and installation work. Its uses include drilling masonry for conduit, sprinkler hangers, foundation bolt holes, pipe lines and drains as well as tearing out brick-work for doors and windows and similar demolition jobs. The J-10 is air-powered. STEAM-JET REFRIGERATION Inhere refrigeration is needed down to 35F, and a supply of steam is available," the I-R system of Stream-Jet Waterr Vapor Refrigeration should be consid ered. In this system water is the only refrigeration medium. It is cooled by direct evaporation in a high vacuum created by steam-jet booster ejectors. There are no moving parts, no vibration, nor noise. Sizes run from 30 to 1000 tons of refrigeration and can be built to oper ate at any one of a wide range of pres- sures down to 1 lb per sq in. I-R COMPRESSORS ALL TYPES AND SIZES I-R Compressors are offered in all sizes and types from V to 3000 hp, in pressures from a few ounces to 15000 lbs, and in stationary or portable models. Air-cooled uuits range from l/t to 90 hp. I-R Water systems are available for industrial and domestic uses. 1342 INTERNATIONAL HEATING & VENTILATING EXPOSITION THE AIR CONDITIONING EXPOSITION Permanent Address--Grand Central Palace, New York 17, N.
