ARMSTRONG INVERTED BUCKET STEAM TRAPS APPLICATIONS. Armstrong manufac tures inverted bucket steam traps for any pressure from 0 to 2400 psig; for dis charging to high pressure, gravity or vacuum returns; for draining mains, risers, coils, heaters, radiators, unit heat ers and process equipment. FEATURES. High Quality Mechanisms in Armstrong traps for low and medium pressures are identical in design, work manship and materials to those used in traps for 900 psi, 900F. from 500 to 1500 cu ft free air per hour when steam is first turned on. High Capacity for Size. The patented free-floating lever mechanism makes pos sible wide opening of discharge orifices large for overall trap size and price. Arm strong capacity ratings, based on actual tests with hot condensate, are entirely reliable. Automatic Air Discharge. Standard traps discharge normal amounts of air along with condensate.

The larger sizes seldom require the extra cost of strainer protection. Quick-Acting. Condensate and air are discharged as fast as they reach the trap, providing fast heatup and maximum temperatures. CHOICE OF BODY STYLES. In the most commonly used sizes, Armstrong traps are available in several body styles to simplify, and reduce the cost of, in stallation. Side Inlet Series. Traps number 800,811, 812, 813, 814 have horizontal and oppo site pipe connections. Capacities and mechanisms of 811, 812, 813, 814 are identical to traps 211, 212, 213, 214. Integral Strainer Models. No. 880, 881 and 882 traps have strainers in the trap body; otherwise identical to 800, 811, and 812 traps. No. 880 lists at $11.50, 881 at $16.00, 882 at $25.50. They cost less to buy and install than a trap plus separate strainer. Right Angle Trap. No. 801 capacity and price identical to No. 800 listed in table. For replacing old radiator traps or wher ever angle connections are simplest. Bottom Inlet Traps. No. 211 through 216 have bottom inlet top outlet connections. TECHNICAL LITERATURE.

ARMSTRONG STEAM HUMIDIFIERS For Stores, Offices, Hospitals, Factories, Laboratories Operation. These units provide auto matic, closely controlled humidification by introduction of steam directly into the room. Installation is comparable to unit heaters. A solenoid discharge valve on the hu midifier is controlled by a sensitive humidistat: A fan or venturi nozzle aids steam dispersal. Where an electric spark is an explosion hazard, air operated models are available. A large model for installation in air ducts and central heat ing systems is also made. Capacities range from 31 to 630 Ibs/hr steam. Advantages. Installation cost is as much as 80 per cent less than some types. The smallest unit, capable of humidifying up to 40,000 cu ft, lists at $182.25 complete with control. No extra load on the heat ing system. No dripping--any moisture in the steam is re-evaporated in the steam - jacketed separating chamber. Control is accurate within a few per cent R. H. Bulletin No. 1775 gives complete data on required relative humidities, selection and installation of Humidifiers.
