A proposed design for the refrigeration laboratory for the greater Armour Institute of Technology . ACKAGE RT^FRlGSRATINrT SYSTSiTYPE G The Creamery Package Manufacturing Companywas one of the first to engage in the manufacture .of refrigerating machines. Their staff of serviceand installation engineers are the peer,in lengthof experience and any similar organiza-tion in the country. In general design the machinesare small and compact and take very little roomfor the tonnage developed. They are ideal for belt-ing direct to electric motors. The Type C repre-sents the best in tv/in cylinder vertical designfor this caoacity. The wide popularity of theserefrigerating systems is excellent testimony tothe efficiency of this method. TAiile each unithas its own distinctive features,the ammonia com-pressor is ofcourse the most important. CP vertical ammonia compressors,master-builtare of the single acting,enclosed,self-oiling are built of semi-steel and are designed f )rlong and constant use. The bearings are exceeding-ly large and are readily renev/ed. A specially de- 45.
