Refrigerant Purgers Representatives in Principal Centers ARMSTRONG INVERTED BUCKET STEAM TRAPS Armstrong offers a complete line of traps for draining low and medium pres sure steam headers, pipe coil radiation, unit heaters, air conditioning equipment, process equipment, etc., to gravity or vacuum return systems. Armstrong de sign and construction results in fast heat ing, uniformly high temperatures and long trap life with low maintenance. 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. Depending on size, air handling capacity ranges from 500 to 1500 cu ft free air per hour. No. $00-813 No. 311-316 Side Inlet Traps 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 action of 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. 36 pages of data on traps, selection, installation and maintenance. A usable handbook for any engineer dealing with traps. Free copy on request. ARMSTRONG STEAM HUMIDIFIERS For Stores, Offices, Hospitals. Factories, Laboratories Operation. These units provide auto matic, closely con trolled humidification by introduction of steam directly into the atmosphere. In stallation is compara ble to .that of unit heaters. Steam at 10 psi or less is required. A solenoid discharge valve on the hu midifier is controlled by a sensitive humidistat. A fan mounted on the humidifier aids in steam dispersal,, or a venturi nozzle can be supplied. Where an electric spark might represent an ex plosion hazard, compressed air operated models are available. In addition to the unit humidifier illustrated, there is a large model for installation in large air ducts and central heating systems. Capacities range from 31 to 630 lbs of steam per hour. Advantages. Installation cost of Arm strong Humidifiers is as much as 80 per cent less than some types of equipment. The small C-2 unit lists at $120.00 com plete with fan and motor, humidistat, strainer and steam trap. Operation, us ing steam at around $1.00 per ton, is economical. There is no extra load on the heating system. No dripping--any moisture in the steam is re-evaporated in the steam-jacketed separating cham ber. Control is accurate within a few per cent R. H. There is almost no noise with open nozzle types. Bulletin No. 1771 gives complete data on required relative humidities, selec tion and installation of Armstrong Humidifiers. Available on request. ARMSTRONG NON-CONDENSABLE GAS PURGERS Armstrong Purgers automatically remove air and other noncondensable gases from refrigerating systems, with minimum loss of refrigerant. Refrigerant gas is condensed in the cap of thepurger, causing non-condensables to sepa rate out at the top from where they discharge through a needle valve. These purgers are suitable for systems from 12 to 500 tons capacity. Body is forged steel, interior parts stainless steel. Purger for Ammonia, Freon, etc., lists at $200. Heavier model for COj lists at $350. BULLETIN NO. 192 describes benefits of purging, gives complete data on installation and operation of Armstrong Purgers. Avail able on request. . HIGH SIDE FLOATS. For compression type refrigerating systems where all of the liquid refrigerant can be carried on evaporating side. Identical to Armstrong Steam Traps except for bucket weight. Ask for BULLETIN 178.
