The refrigerant flows in the opposite direction through the outer tube--also of copper. The brass header is machined from a solid brass bar and is designed to permit easy cleaning of the inner cooling tube, thus maintaining the high original cooling effi ciency throughout the long life of the condenser. Mr. Halstead writes--"Frequently wc are asked O&utconcCz COPPER AND BRASS THE AMERICAN BRASS COMPANY General Officni Weterbury 88, Connecticut Subsidiary of Anoconda Copper Mining Company In CiMfu Anaconda Amuican Bax** Ltd., Now Tbrenfo, Onf.

Brass was selected for headers as a rustproof material of uniform density suitable for high-speed machining and dependable high-tem- perature brazing. Alt tubes are of copper for high thermal conductivity, corrosion resistance, long life and good brazing properties. u!n our condenser assemblies it is of prime im portance that we use 8 combination of materials that makes possible maximum production with a minimum of leaks.
