Refrigerant Purgers Represents tives 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. Armstrong de sign and construction results in fast heat ing, uniformly high temperatures and long trap life with exceptionally low main tenance. 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. Depend ing on size, air handling capacity ranges from 500 to 1500 cu ft free air per hour. Side Inlet Traps Pipe Connections...................... List Price (Regular).................

The high leverage of the patented free-floating lever makes it possible to open discharge 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-drawing. Seif-Cleaning. Swirling action of condensate 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 pres sure 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, installa tion and maintenance. A usable hand book for any engineer dealing with traps. Free copy on request. ARMSTRONG STEAM HUMIDIFIERS For Stores, Offices, Hospitals, Factories, Laboratories Operation. These units provide automatic, closely controlled humid ification by introduction of steam directly into the atmosphere. Instal lation is comparable to that of unit heaters. Steam at 10 psi or less is required. A solenoid discharge valve on the humidifier is controlled by a sensitive humidistat. A fan mounted on the humid ifier aids in steam dispersal, or a venturi nozzle can be supplied. Where an electric spark might represent an explosion hazard, compressed air operated models are avail able. In addition to the unit humidifier illustrated, there is a large model for in stallation 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, using steam at around $1.00 per ton, is economi cal. There is no extra load on the heating system. No dripping--any moisture in the steam is re-evaporated in the steamjacketed separating chamber. Control is accurate within a few per cent R. H. There is almost no noise with open nozzle types. Bulletin No. 177 gives complete data on required relative humidities, selection and installation of Armstrong Humidifiers. Available on request. ARMSTRONG NON-CONDENSIBLE GAS PURGERS Armstrong Purgers automatically remove air and other non- condensible gases from refrigerating systems, with minimium loss ol refrigerant. Refrigerant gas is condensed in the cap of the purger, causing non-condensibles to separate out at the top from where they discharge through a needle valve. These purgers are suitable for systems from 12 to 1200 tons capacity --Ammonia, Freon, COi and other refrigerants. Body is forged steel, interior parts stainless steel. List price is $200.00 BULLETIN NO. 173-A describes benefits of purging, gives complete data on installation and operation of Armstrong Purgers. Available on request.
