Air Conditioning * Westinghouse Electric Elevator Company [ Vil/fl Air Conditioning Department 150 Pacific Avenue -- Jersey City, N. J. Offices and Contractors in All Principal Cities What's Different about Westinghouse Equipment? THE IMPORTANT difference is in the compressor--vital heart of any air conditioning system. It's Hermetically-Sealed. Westinghouse developed the hermeti cally-sealed compressor in 1935. It was the first, and is still the only application of the hermetically-sealed principle to multiple horsepower Freon-12 compressors. Thousands of installations have proved these advantages: No Seal Leaks, because shaft seals are* eliminated. Installation in Unventilated Spaces. Practical because the motor is refrigerant-cooled. High Efficiency. Direct-drive mechanism eliminates the power loss common to belt-driven equipment. Completely Enclosed operating mechanism. Power is sealed in, trouble is sealed out. There are no visible moving parts, yet all parts are readily accessible without dismantling, through side service plates. Light Weight. Lightest weight per ton of cooling effect of any compressor on the market. No special foundations needed. Com pact size is a natural collateral advantage. Capacity Modulation is built in. The floating-reed design of the patented, improved head valve permits the built-in application of a capacity modulator that provides completely flexible operation of the compressor to meet exact load requirements. Westinghouse Hermetically-Sealed Compressors are currently available iii sizes from 5 Horsepower to 100 Horsepower. 896 Westinghouse Electric Elevator Company Air Conditioning Central Systems Westinghouse Synchro-built Equipment For each Westinghouse Compressor, there is Synchro-built equipment, designed and built to operate efficiently in a complete Westinghouse system that meets the specific needs of the job. This equipment includes: Heat Transfer Surfaces Coils for Freon, steam, hot and cold water, are available in such a wide range of sizes that any practical design specifications are readily met. The patented header of the Freon evaporator assures immediate and complete distribution of the gas over the entire coil surface. Air Conditioning Units Vertical and horizontal units, for air conditioning and refrigeration, are provided in sizes to meet all needs. The cabinets are complete with quiet, blower-type fans, and facilities for installation of cooling and heating coils, filters and humi difiers. Condensers Water-cooled and evaporative con densers are matched to the per formance ranges of each compressor. Where water is plentiful and cost low, Westinghouse Water-cooled Condensers meet every require ment. Westinghouse "Aquamiser" evaporative condensers combine the most desirable features of water-cooled condensers, air-cooled condensers and cooling towers. Factory-Built Systems Factory-built complete centralplant systems known as the Unitaire are available in five sizes--from lx/i to 25 hp. For requirements within these ranges, they offer ease of handling, quick installation, low cost. They com bine ' the complete refrigeration cycle, controls and blowers within a single, compact, easily installed cabinet.. 897
