Refrigerant Purgers Representatives in Principal ' Centers ARMSTRONG INVERTED BUCKET STEAM TRAPS Armstrong offers a complete line of traps for draining low and high pressure steam headers, pipe coil radiation, unit heaters, air conditioning equipment, process equipment, etc., to gravity or vacuum return systems. Automatic Air Discharge. Standard traps automatically discharge normal amounts of air along with condensate. Where large amounts of air must be vented quickly when steam is first turned on, Armstrong. BLAST Traps with thermic bucket vents are recommended. Air handling capacity, ranges from 500 to 1500 cu ft free air per hour. NEW! Traps with integral strainers save-fittings, labor. No. 880 with same capacity as No. 800 listed below is $11.50. No. 881 with same capacity as No. 811 is $16.00. Both cost less than traps plus separate Btrainers. Capacities, Prices, Dimensions Note that capacities of No. 811, 812 and 813 traps are the same as No. 211, 212 and 213 respectively. On most installations, the engineer therefore has a choice of side inlet--side outlet or bottom inlet-- top outlet body styles. jvo Side Inlet Traps No. 800 No. 811 No. 812 No. 813 Pipe Connections...........................

The high leverage of the patented free-float ing lever makes it possible to open dis charge orifices which are very large for over-all trap size. Positive Action. The discharge valve is either wide open or closed tight. Fast opening and closing prevent wire-draw ing. Self-Cleaning. Swirling actionof con densate during discharge carries dirt through trap. There are no dead spots for dirt to collect. High Quality. 18-8 stainless interior parts. Valve and seat are chrome steel, hardened, ground and lapped. Low pressure trap parts same material and quality as those used for 1500 psi, 900 F. Armstrong Steam Trap Book. 44 pages of data on traps, selection, instal lation and maintenance. A usable hand book for any engineer dealing with traps. Free copy on request. TRAPS FOR UNIT HEATERS Armstrong inverted bucket steam traps are particularly suitable for drain ing low or high pressure unit heaters to vacuum or gravity return systems for these reasons: 1. Air and CO, are vented automati cally each time the trap opens--keeps heaters hot, helps prevent corrosion. 2. Condensate discharges at steam tem- Eerature as it accumulates--keeps eaters at maximum temperatures. 3. No build-up of back pressure in return lines. 4. Armstrong traps seldom require maintenance. A Bulletin with Btu output figures for 24 makes of unit heaters explains how to select traps. Available upon request. ARMSTRONG STEAM HUMIDIFIERS For Stores, Offices, Hospitals, Factories, Laboratories SOLENOID VALVE OPEN IT HIMXNSTAT CALLING FOR MOISTURE Operation- These units provide auto matic, closely controlled humidification by introduction of steam directly into the atmosphere. Installation is com parable to that of unit heaters. Steam at 15 psi or less is required. A solenoid discharge valve on the hu midifier is controlled by a sensitive humidist&t. A fan mounted on the strong Humidifiers is as much as 80 per cent less than some types of equipment. The small C-2 unit lists at $182.25 com humidifier aids in steam dispersal, or a plete with fan and motor, humidistat, venturi nozzle can be supplied. Where strainer and steam trap.
