This valve consists of a regular type packless radiator valve with a cartridge or tube made up of a series of orifices and baffles capable of setting up any required frictional resistance. This mefhod of establishing any desired resis tance does away with elaborate calcu lation of pipe sizes. Grinnell guarantees perfectly balanced circulation to each and every radiator where these valves are installed throughout the system. Equiflo Data Book sent to interested parties.

Healing Systems Hot Water and Industrial Piping 7hermouer Patented THE GRINNELL UNIT HEATER Industrial Type De Luxe, Industrial and Factory Types-- 125 Lb W.S.P. Thermolier is a ruggedly built unit heater whose efficiency and dependability have been proved by actual performance in field service. Thousands of them are installed in industrial buildings and commercial structures of all types of occupancy. Thermolier has 14 points of superiority, the most outstanding of which is the internal cooling leg built right into the unit, an exclusive Ther molier feature. See drawing below. Radiation is from brass-finned seamless copper U-tubes rolled into a cast-iron tube sheet. No solder is used for strengthening joints and there are no flat horizontal surfaces to catch dirt. Units may be controlled manually or automatically, singly or in groups. Installation and piping are extremely simple and inexpensive, hence the unit may be moved from one THE THERMOLIER INTERNAL COOLING LEG ACCOMPLISHES A RESULT SUCH AS IS DIACRAMMATICALLY ILLUSTRATED HERE THERMOSTATIC TRAP ._______ _ UNIT HEATER location to another at small cost if found desirable on account of changes in building or occupancy. The complete line includes 27 Models in DeLuxe Type, and 35 Models each in Industrial and Factory Types. Thermoliers provide maximum distribution of heat without objectionable drafts. Specifications Fan--Grinnell special of rugged construction. Motor--heavy duty, oversize, enclosed, moisture-proof. Housing--Art Metal Slate gray finish with chromium trim on DeLuxe Types. Copper on Industrial Type with rubbed lacquer finish; steel on Factory Type finished in gray lacquer. Frame--Heavy pressed steel, providing rugged support for motor and fan. Special Features--Adjustable swivel hanger rod couplings; louvers rigid, but easily adjustable: integral cooling leg insuring perfect drainage through one thermostatic trap for pressures up to 25 lb. For pressures not exceeding 125 lb, a thermostatic trap of proper construction can be used and should be attached directly to the unit.
