Heating Systems NEW YORK Mueller Co. Decatur, Illinois Branches SAN FRANCISCO DALLAS 1 CHICAGO Heating System Service--The Mueller H-9500 Heating System ig designed to automatically supply water to hot water heating boilers and to automatically discharge water should the pressure approach a danger point or boiler guarantee. The damper control affords automatic draft with reduced fuel consumption and more even room temperatures. The entire unit lends itself to clean, efficient and safe heating without fear of forget fulness or carelessness, both of which, as human ele ments, are destructive and dangerous. Size--The Mueller Heating System is made in Yi size only and is adapted for any job up to and including three stories in height or comprising less than 15,000 sq. ft. radiation. Construction--All valves have removable seats of bronze with special composition seat disc and with phosphor bronze diaphragm, which are extremely re sistant to corrosion and high temperature. All valve working parts are of bronze with close fitting joints and without sediment collecting pockets. The large sediment collecting chamber with in verted wire screen basket' prevents any particle of sand, pipe scale, or chips entering valves and interfering with their operation. Engineers and contractors will recognize ,the dependability of the Mueller Heating System because careful designing as a result of many years experience have eliminated: (1) Rubber or solder joint in diaphragm; (2) Soft and easily corroded seat disc; (3) Possibility of creating excess pressure; (4) Sediment or lime collecting pockets; (5) Complicated valve mechanism; (6) Corrosive metal working parts; (7) Close fitting guides or guide rings; (8) Working parts which cannot be easily replaced. The big Mueller Heating System is designed correctly with proper diaphragm area for long and dependable service. Regulator Service---The Mueller H-9000 Pressure Reducing and Regulating valve is suitable for hot or cold water and air. It is especially adapted for residence, building, apartment and industrial service. Sizes---K*, Yi W, W, 1", 1%", \W, 2" and 2W. Construction--The H-9000 valve is made entirely of brass and bronze. The full seat opening insures a full volume of water even at the reduced pressure. Valves are regularly stocked for initial pressures up to 250 lb. and delivery pressures from 20 to 75 lb. All valves are set at 45 lb. unless otherwise specified. H-9000 Relief Valve Service--The Mueller H-9045 is designed to relieve dangerous and excess pressures. It is particularly adapted to hot or cold water in stallations but will serve equally as well on air or oil. Size--y-i size only with outside thread inlet; y inside thread outlet. Pressure Ranger-Valves are carried in stock set at maximum relief pressures of 50, 75, 100, 125 and 150 lb. Valves can be supplied set at any pressure between 50 and 150 lbs. upon request. To insure prompt delivery order stock valves. H-9046 694 Heating Systems Thrush Differential Pressure R,,ef H. A.

Thrush Electric Water Circulator Thrush Automatic Da"Per R<*u,9tor vs- WKTtn SUPPLY Thrush System comprises equipment to be added to any unregulated gravity Hot Water Heating plant to make it a "Closed System" operating under additional pressure and with automatic control of damp ers. It increases heat trans mission and reduces fuel consumption. It is made in four types as listed below. DATA and SPECIFICATIONS Class AA Equipment consists of Thrush Differential Pressure Relief Valve, Automatic Temperature Damper Regulator, Pressure Reducing Valve, Copper Bearing Steel Pressure Tank and special Gauge and Thermometer. It is automatic filling. Class A Equipment This is the same as Class AA Equipment except that it has no Pressure Reducing Valve for automatic filling. Reducing Valve, Copper Bearing Steel Pressure Tank and special Gauge and Thermometer. It is automatic filling. Class B Equipment Same as above except that it does not have Pressure Re ducing Valve for automatic filling. Sizes Class BB Equipment Cousiste of Thrush Differential Pressure Relief, Pressure Reducing Valve, Copper Bearing Steel Pressure Tank and Special Gauge and Thermometer. Size No. 0 up to 350 sq. ft. of radiation Size No. 1 up to 700 sq. ft. of radiation Size No. 2 up to 1200 sq. ft. of radiation Size No. 3 up to 2000 sq. ft. of radiation Automatic Dual Control Unit An inexpensive heating system for competitive job. The Automatic Dual Control Unit may be used for small to medium sized hot water heating plants, easily and economi cally, by merely installing the Dual Control Unit in the water supply line. Furnished with strainer. ; Fig. Thrush Differential Pressure Relief This valve is de signed with large valve Thrush Automatic Temperature Damper Regulator Fig. s area and has a capacity for relievingexcess pres sure for both large and small installations. The valve seat is submerged in water, so designed that corrosion or sedi ment accumulation is prevented. It is always Safe. (Tapping % in.). The operation of this Regu lator depends upon the tem perature change of the water circulat- 1 ing through the' heating system and not upon pressure. Fig. 4 Easily installed and very efficient. (Tapping 1M in-)- Thrush Electric Circulator Here is a method of assuring positive circulation on any Hot Water Heating job. The Thrush Electric Circulator will pay for itself in less than one season in fuel saving. Highly recommended for oil and gas fired boilers, also for green houses, garages, apartments, store buildings, works perfectly with blower units. Cheaper to install than low pressure steam, vapor or vacuum vapor jobs. 110 or 220 A.C. 60 cycle motor for light or power line. Low operating cost.
