' Air System Equipment Air Conditioning Westinghouse Electric Corporation Slurlevanl Division EVAPORATIVE CONDENSERS Where water is scarce or expensive, or its use or disposal restricted, the "Aquamiser" provides savings in water consumption. Westinghouse Aquamisers are available in sizes to give a range of capacities from approximately 5 tons to 100 tons each, net refrigeration effect. WATER COOLED CONDENSERS Where sufficient water is available from city water supply to cooling tower the water-cooled condenser is economical and efficient. To economically match refrigera tion load requirements, Westinghouse water-cooled condensers are available in 14 sizes, ranging in nominal capacities from 2 to 100 tons net refrigeration effect. WATER CHILLING UNITS For the chilling of water for distribution to a number of cooling coils, for surface de humidifiers and for use in industrial pro cesses, these efficient water-chilling units range in size from 5 to 110 tons net refrig eration effect. The chiller, located close by the compressor, eliminates long re frigerant piping or long duct runs. HEAT TRANSFER SURFACES Direct expansion coils with patented re frigerant distributor, chilled water coils, steam and hot water coils are available in a great many sizes for all types of systems. AIR CONDITIONING UNITS Two types' are available--a horizontal type for ceiling suspension and a vertical type for floor installation. In the hori zontal and vertical types, year-round air conditioning is accomplished by the in stallation of cooling and dehumidifying surfaces for summer, and heating surfaces for winter air conditioning. 1034 Air Conditioning Unit, Type AH Air System Equipment Air Conditioning Westinghouse Electric Corporation Slurlevanl Division AIR WASHERS Three types are available--Type H, with one bank of nozzles, used primarily for humidifying; Type C, with two banks of nozzles, used for evaporative cooling, humidifying and dehumidifying; and Type S, with one bank of nozzles, used for humid ifying, especially where space is limited. FILTER-WASHERS Self-cleaning filter-washers employ a bank of mineral wool, or glass fiber filter pads, in conjunction with water sprays to clean and humidify the air. Made in 72 standard sizes and to specifications. SURFACE DEHUMIDIFERS Available for either chilled water or directly expanded refrigerant, these wet surface units control accurately wet and dry bulb conditions in industrial and com fort air conditioning systems. Capacities range from 2000 to 50,000 cfm, with cool ing capacities of 5 to 250 tons of refrigera tion. CENTRIFUGAL FANS Sllentvane*, Design 8, are high speed, exceptionally quiet heating and ventilating fans engineered for installations where fan noise cannot be tolerated. Made in 21 sizes with rotors from 12% in. to 87% in. in diameter, they operate from free delivery to 4 in. water gage static pressure, and at a maximum tip speed of 9000 feet per minute. Capacities range from 700 to 400,000 cfm. Multivane, Design 6, high capacity, low speed fans, suitable for use in public buildings because of low tip speed, low out let velocity, and small size for a given duty. With wheel diameters up to 87 in., they operate against static pressures up to 4 in. water gage, and at a maximum tip speed of 6000 fpm. Capacities range from 400 to 450,000 cfm. Reg. U. S: Pat.
