Where sufficient water is available from city water supply, or where a cooling tower is used. the water-cooled condenser is economical and efficient. To match economically refrigeration load requirements. Westinghouse water-cooled condensers are available in 14 sizes. ranging in nominal capacities from 2 to 100 tons net refrigeration effect.


Vertical. semi-flooded type. Freon 12, water coolers for the chilling of water for distribution to cooling coils in indirect air conditioning systems and for surface dehumidifiers. These efficient water-chilling units range in size from 5 to 110 tons net refrigeration effect.


Direct expansion coils with patented refrigerant distributor. chilled water coils, steam and hot water coils are available in a great many sizes for all types of systems.


Two types are available-a horizontal type for ceiling suspension and a vertical type for floor installation. In the horizontal and vertical types. year-round air conditioning is accomplished by the installation of cooling and dehumidifying surfaces for summer, and heating surfaces for winter air conditioning.


Three types are available*'l'ype 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 humidifying, especially where space is limited.


Self-cleaning filter-washers employ a bank of mineral wool, or glass fiber filter pads, in conjunction with water sprays to clean and humidity the air. Made in 72 standard sizes and to specifications.


Available for either chilled water or directly expanded refrigerant. these wet surface units control accurately wet and dry bulb conditions in industrial and comfort air conditioning systems. Capacities range from 2000 to 50,000 cfm. with cooling capacities of 5 to 250 tons of refrigeration.


PROPELLER FANS, DESIGN 7, with direct-connected motors. are generally applicable to all air exhausting or ventilating problems when unit blows air directly outdoors or to another room, without ducts or high resistance to air movement. Motors are totally enclosed special

fan duty type. Design 7 Propeller Fans are made in 7 sizes, from 12" to 36" diameter. and 815 to 11,050 cfm.


SILENTVANER 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 lZI/4" to 87%" in diameter. they operate from free delivery to 4" water gauge static pressure. and at a maximum tip speed of 9000 feet per minute. Capacities range from 700 to 400,000 cfm.


This electronic air cleaner is designed for installation in the duct of an air conditioning or ventilating system to remove air-borne dust and dirt particles. with an efficiency of 900/o by blackness or discoloration test. Made in sections. it can be applied to systems of 1200 cfm and over. PRECIPITRON high cleaning efficiency reduces the cost of redecorating and cleaning by removing dust and dirt particles from the air which are too small to be removed by conventional mechanical filters.


Unit ventilators filter. heat and circulate air through room areas. Each unit is equipped with heating coil, a fresh air inlet. motor driven fans. and controls, all enclosed in an attractive steel cabinet. Available in

auditorium type units for heating auditoriums and similar large room area.
