REFRIGERATING PLANT 



THE cooling of 

 the drinking 

 water used 

 throughout the Singer 

 Building is produced 

 by means of the most 

 modern and up-to- 

 date refrigerating ma- 

 chinery. 



The water used in 

 the drinking-water 

 system is first put 

 through a battery of 

 water filters, after 

 which it is forced into 

 the cooling tanks. 



These tanks are 

 two in number, one 

 for high-pressure ser- 

 vice and one for low 

 pressure. Each tank 

 is 42 inches in diameter 

 and 10 feet long, and 

 is provided with ap- 

 proximately 1,025 feet 

 of 1-J-inch extra heavy 

 continuous welded pipe 

 coils. These coils are 

 arranged with all the 

 necessary headers, 

 valves, fittings and con- 

 nections for the circu-- 

 lation of cold brine. From this combined cooling and 

 supply tank, the water is circulated throughout the 

 entire building and Tower by means of two stage 

 turbine pumps, these pumps being directly connected 

 to motors. There are three of these pumps, each 

 having a capacity of 50 gallons per minute; two 

 of the pumps are designed for a working pressure 

 of 300 pounds per square inch, and one for 100 pounds 

 per square inch. The refrigerating machine of this 

 plant is provided with two vertical single-acting com- 

 pressors, driven by a Corliss -Valve Engine. This 

 machine, as well as the balance of the refrigerating 

 machinery throughout the plant, was built and 

 installed by the York Manufacturing Company, of 



I" 99 



York, Pa. For cooling the brine circulated in the 

 water-cooling coils two double-pipe brine coolers 

 are used, each cooler being 12 pipes high and 

 18 feet 2 inches long of 2-inch and 3-inch pipe. 

 The brine is taken from a brine supply tank 

 and circulated through the brine coolers and water- 

 cooling coils by means of a duplex direct-acting 

 pump. 



In connection with this water-cooling system a 

 small freezing system is installed, which produces 

 from 500 to 1,000 pounds of ice per day. This 

 system has proved very satisfactory, and gives a 

 continuous supply of cold drinking water throughout 

 the building at all times.
