Finn Patented No Tank Water Supply Systems. Finn Fuel Saving Condensation Pump and Receiver Returns condensation from radiators and return lines below the water line of boilers in all kinds of buildings, drying kilns, greenhouses, etc., also forces circulation in hot water heating systems. Finn fuel saving condensation pump and receiver can be located on a level with or below the boiler. By means of automatic electric control (furnished with the pump), it will return condensation from and eliminate sluggishness in all radiators, coils and return lines that are on a level with or below the boiler, permitting them to be filled with live steam instead of cold condensation. stcam main 7-0 all For larger operations, two or more pumps can be connected effecting great saving in elec tricity ana fuel.

Finn Drinking Water Circulating and Booster Pumps Used for circulating drinking water in all classes of buildings: hospitals, schools, institutions, hotels, restaurants, factories, and office buildings. These pumps are the same as those used in the Finn water supply system described in opposite column. Entirely Closed Method--A sanitary and economical method by which drinking water is cooled in the pipe main which is coiled at any desirable location, the coil being contained in a wood In returning the condensation to the boiler inter mittently, the Finn pump creates a vacuum in the system, permitting the water in the boiler to boil at a lower temperature and, consequently, reduces the fuel consumption. In addition to the fuel saving feature, a better circulation is produced in all return lines, consequently these lines become very hot and serve as additional radiation. The pump is the same as that used in the Finn water supply system described on the following page. It consists of only a few parts, is made of high grade materials, and, because of its simplicity, is hot expensive. Impeller touches water only. No metal rub; no wear. The cost of the electricity required is insignificant. Capacities--No. 1 pump, 4000 sq. ft. of direct radiation; No. 2 pump, 7000 sq. ft. direct radiation.

Box can be placed either below, above or level with basement or any floor regardless of location of pump, and the box should have a drain as Bhown in the sketch. Ice can be packed around the coil in the box, or, if a refrigerating machine is used, the brine pipe of the latter can be run to and coiled inside the box. there being room for both the brine coil and the coil containing the drinking water. Check valves shown in sketch keep the cold water from backing up into the street or building main and also send make-up water direct to the coils and pump. The closed method, using either a No. 1 or No. 2 Finn Pump, will provide abundant circulation and take care of maximum demands during rush periods in the largest buildings.

The relief valve partly closes when faucets or fountains are open: when the latter are closed, the relief valve opens a little more permitting water to return to the tank, thereby maintaining constant circulation. The open system requires one No. 2 Finn pump, or for large operations; two No. 2 pumps to take care of great demands in rush periods.
