An Ingersoll-Rand 425-ton steam jet water vapor refrigeration unit in a butadiene installation.
. L a r g e steam jet ejectors, while based o n a relatively old principle, are today utilized to produce refriger ation. In its new dress, a jet of live steam at 2 psig or m o r e darting in a properly-designed venturi tube greatly "reduces the pressure over warm -water. T h e jet also removes water vapor, thereby maintaining the vacuum and l o w e r i n g the temperature of the water to that at which it boils, which may be as low as 35° F. Such coolers are in use today in many industries, such as: PAPER . MARINE · BREWING · FOOD RUBBER . CHEMICAL . OIL REFINING AIR CONDITIONING · GAS PRODUCTION EXPLOSIVES
Revere is interested in this develop ment for two reasons. First, it is a fine example of the way in which American enterprise uses its intelligence and initiative to obtain new values from old ideas. Second, the coolers use steam and water, and require nonrusting c o p p e r alloys of high heat conductivity in such forms as conden ser and heat exchanger tubes and plates, which Revere m a k e s . . . . Revere has a great deal of information about its alloys and their applications t o various conditions of use. Why not use that k n o w l e d g e as well as our metals? T h e Technical Advisory Serv ice will gladly cooperate with you.
