Air Conditioning Unit Heaters and Coolers McCord Corporation AIR CONDITIONING AND REFRIGERATION DIVISION Detroit 11, Michigan FACTORIES: DETROIT, MICH., WASHINGTON, IND., WINDSOR, CANADA MANUFACTURERS OF UNIT HEATERS, CONDENSERS FOR DOMESTIC AND COMMERCIAL REFRIGERATORS MCCORD HORIZONTAL TYPE UNIT HEATERS 16 models for industrial, commercial general office, and store use--a type size and design for every application. Features: modern design, high capacity. Air Conditioning Unit Heateis and Coolers U. S. PAT. OFF. J. Murray Manufacturing Co. Wausau, Wisconsin Offices in Principal Cities MANUFACTURERS OF GRID UNIT HEATERS AND GRID BLAST COILS Designed and testedto operate with steam or hot water systems--for steam pres sures from 2 lbs to 250 lbs. Engineered along the same lines as the standard GRID Unit which had aluminum heating sections and has been on the market since 1929. MCCORD VERTICAL TYPE UNIT HEATERS 12 models for overhead installation--up near the ceilings, in bays, or at low levels in offices and stores. McCord unit heaters incorporate every unit heater advancement that McCord en gineers and the experience of thousands of users could suggest. The spiral fin tube surface as used in McCord horizontal and vertical types provides a type of heat trans fer surface of maximum efficiency. Constructed entirely of copper, the fins are bonded by solder. The solder protects the fins from external corrosion, prolonging the life of the heating element. Individual tubes prevent stresses due to unequal expansion. Tube headers are rounded for strength. Improved fan blades deliver large quantities of air with minimum noise or vibration. The design of the die-formed air inlet is an improvement that increases air quantity and decreases noise and horsepower. The motor support is nonair-resrticting. Standard base type motors are used, making replacement easy if it should ever be necessary. CONDENSERS FOR DOMESTIC AND COMMERCIAL REFRIGERATORS McCord refrigeration condensers are fab ricated by the most modern and econom ical methods, resulting in a high quality product at low cost. The McCord con struction permits use of continuous tubing without joints, eliminating possi bility of leaks. Fins are permanently copper-brazed to the tube. Complete range of sizes. 1162 One piece construction "fin" heating sections of high test cast iron--no sol dered, brazed, welded or expanded con nections. Patented.
