Facts about Union Carbide and POLARSTREAM

Refrigeration

Introduced in 1961 POLARSTREAM represented a new concept in refrigerated transport, employing liquified nitrogen gas as its source coolant. Mechanically simple, the system consists of a vacuum-insu- lated storage container, a control valve, a temperature controller, a spray header, and attendant plumbing As the liquid nitrogen is discharged into the container, it instantly vaporizes and expands throughout the cargo area, provid- ing uniform temperature control in minutes. • Union Carbide virtually "invented" liquid nitrogen, installing America's first air separation plant in 1907.

Since that time Union Carbide has been the acknowledged leader in producing liquified gases and in pioneering the equipment and technology that have made these cryogenic fluids practical and economical to use. • POLARSTREAM refrigeration is only one instance of Union Carbide's broad, diverse involvement in the production and protection of food.

An involvement that ranges from plastic seed tape for planting crops to GLAD Wrap, a plastic film used for storing leftovers from the table.

Another liquid nitrogen system pro- vides a fast, economical means for processors to freeze foods.

The POLARSTREAM mer Clip-on...a new concept in refrigerated shipping.

Suddenly a new era in ocean-going containerized shipping is at hand. New ships, equipped with central refrigeration to handle below-deck containers, are making containers with built-in refrigeration obsolete.

This development solves many old problems, creates many new opportunities.

Container costs go down; container life expectancy goes up.

Safe, reliable POLARSTREAM clip-on units refrigerate containers before load- ing aboard ship and after unloading at destination. A fork-lift truck snaps a tank into place on the container and—instantly—there's cooling for overland transit and dock storage.

Utilizing liquified nitrogen (—320°F.) as a coolant, POLARSTREAM units offer... • broadest possible temperature range—ambient down to —20°F. • unmatched dependability and long life—no rotating parts. • low cost—approximately half the investment required for Diesel- electric refrigeration units. • precise temperature control—thermostat-operated valve capa- ble of maintaining any temperature within a 2° range. • silent, safe, non-pollutant—no engine, no flammable fuel storage, no exhaust fumes. • flexibility—units can be used where needed for specific legs of trip, as an "assist" to existing systems, or as a total system for short hauls.

Overland test runs have already demonstrated the advantages of this system. POLARSTREAM clip-on units have recently been specified for use in connection with eight refrigerated ships now under construc- tion for A.C.T. and other shipping lines.

POLARSTREAM refrigeration also offers interest- ing possibilities for the economical conver- sion of existing ships to containerization.
