New Liquid Air Machine in Boylston

A plant for the manufacture of liquid air, purchased out of the Boylston Hall laboratory funds, has recently been installed in Boylston Hall. It consists of a four-stage compressor, built by the Norwalk Iron Works Company, which is operated by a Crocker-Wheeler 20-horse-power motor. The compressed air is condensed by a new and original type of liquefier designed by Professor W. P. Bradley of Wesleyan University and built under his direction. The capacity of the plant, which is the most efficient and powerful yet devised, is about half a gallon of liquid air per hour. The machinery has been installed and tested under the superintendence of the director of the laboratory, Professor C. R. Sanger. The first output of liquid air was immediately employed in research work under the direction of Professor T. W. Richards, and the apparatus will be used frequently to provide material for future investigations in the laboratory.
