ROWER June I?4* .Sibil illustration shows one of the feature* of HM Con* '^densers--deanability. In the word* of the manufacturer. &*?! _"_T_hese new HA1 units combine tun qualities never before obtainable in tube-uiitbin-a-tube, water-cooled condensers--they 're cteanable, and they achieve true counterflow beat-exchange relationship between the coolant and the refrigerant, enabling water require ments to be reduced without sacrificing condenser unit capacity." S^iN IMPORTANT PACTOK oot seeo is the use of Revere seamless ^XV copper tube for both the inner and outer tube* of the condenser, ^:indalso rectangular brass rod for the header bar. This tube as well the bar, must be practically perfect, in order to avoid the possiV'Witj of leakage during the expected normal life of the condenser, V* life which is greatly extended due to the fact that the water tubes sre accessible at both ends for insertion of the spiral cleaning tool. ^;The manufacturer, Halstead & Mitchell, recently gave Revere a pfeasiog but not unusual compliment, saying that no Revere tubes / .hid ever proved defective. ' Revere offers condenser tubes oot only in copper, but in Admiralty Metal, Munu Metal, Rcvalon (Aluminum Drass), Hcrculoy, Brass, -/Uid three types of Cupro-Nickel. See Revere for condenser tubes.
