When a southern chemical corporation wanted to compress nitrogen and hydro* gen to 1S,000 psi in the production of synthetic ammonia, lngersoll-Rand com pressors were chosen for the job. When the aircraft industry needed big vacuum ' pumps to exhaust testing chambers in order to simulate high altitude flying condi tions, again lngersoll-Rand equipment was selected. The installations pictured here are typical of the wide range of specialised services that I-R compressors are performing. If you have a problem involving the compression or evacuation of air or gases, remember that for scores of years lngersoll-Rand has. been designing and building reciprocating, centrifugal, and steam-jet equipment--and combinations of these-- to meet the most exacting requirements in all kinds of industries. Your I-R repre sentative is well qualified to give you expert assistance, no matter what the gas, pressure, or process. ffc Ingenroll-Rand M3-1 ^ 11 BROADWAY, NIW YORK 4, N. Y.
