 AVING given the subject of Mechanical Refrigeration in Freezing and Cold 
 Storage Warehouses, and their design and construction our careful attention 
 during the past ten years, and having done, it is believed, some of the most 
 responsible work in this direction, we take pleasure in presenting, in the 
 following pages, a number of warehouses which have been equipped with the Pontifex- 
 Hendrick system of refrigerating machinery. 
 
 Among these will be recognized some of the best known Cold Storage and Freezing 
 Warehouses of this country, modern in construction and successful in results, and 
 representing the most advanced practice in mechanical refrigeration. All of these 
 houses have earned, in the trade, a reputation for good work, because of the steady and 
 reliable temperatures which they afford and the excellent service which they have 
 rendered. 
 
 We shall be pleased to afford to all interested further information regarding 
 mechanical refrigeration, to furnish designs anti specifications for the construction of 
 cold storage warehouses and to submit estimates, plans and specifications for the 
 refrigerating machinery and the necessary steam and power plants.

 GENERAL ARRANGEMENT OF 
 
 PONTIFEX-HENDRICK REFRIGERATING SYSTEM.

OUR REFRIGERATING SYSTEM. 
 
 The Pontifex-Hendrick refrigerating machine embodies the most advanced 
 ideas in the construction of refrigerating machinery on the ammonia absorption 
 principle, which many years of experience have demonstrated to be correct in 
 practice as well 
 
 ADAPTABILITY. — It is well adapted for the refrigeration of abattoirs, 
 packing houses, chocolate and candy factories, fruit houses, etc. It requires little 
 attention, and is an excellent system for butcher shops and restaurants where steam is 
 available for operating it. In hotels, clubs, apartment houses, office buildings, hos- 
 pitals and other places where vibration and noises are objectionable it is the only 
 system which should be considered at all. 
 
 We are prepared to furnish plants on either the direct ammonia expansion or the 
 brine circulating system. 
 
 We regard our absorption system as specially adapted for the refrigeration 
 of cold storage and freezing warehouses fish freezing plants, paraffine chilling 
 and pressing plants of oil refineries, and all work requiring extremely low 
 temperatures. In this direction we have, we confidently believe, done more 
 meritorious work than all of our more prominent competitors combined. As 
 the tendency of modern refrigerating methods is constantly toward lower tem- 
 peratures, the field for our absorption system is constantly widening. 
 
 DETAILS OF CONSTRUCTION- — All cylinders or vessels connected 
 with our machine are loam castings, and all heads are dry sand castings, of a 
 
 5 
 
special mixture of charcoal iron, close grained, tough and strong; all bolts are of 
 the best locomotive stay-bolt iron; all parts are tested to 500 pounds hydraulic 
 pressure for strength and to 250 pounds air pressure to locate leaks. 
 
 All coils, where of the spiral pattern, are continuously welded, trom end to 
 end, of strictly wrought iron and lap welded pipe, extra heavy and full weight; 
 they are tested to 250 pounds air pressure, while submerged under water, thus 
 disclosing any leaks. The process of coiling subjects the pipe to such rigid 
 tests that any defects in material become at once apparent. In our system of 
 construction there are practically no joints in the brine and water coils that are 
 exposed to the action of ammonia cr are covered by being submerged in water 
 or brine; the only coils which are not of the welded and spiral pattern, are those 
 of the generator and rectifier, which are made of extra heavy lap-welded pipe, 
 with steel return bends. With the one exception of the rectifier coil the am- 
 monia pressure acts in all cases on the outside of the coil, a much safer condi- 
 tion of working than where the coils are subject to internal pressure and hence 
 liable to failure as they become worn. All pipes, valves and fittings for am- 
 monia are extra heavy' and specially' designed to guard against leakage. Our 
 pressure guages are large and ornamental, w'ith tubes bored out of solid steel, 
 and the best of their kind. Our liquid level gauges are of our own design and 
 can be ground tight while in place; they are fitted with an automatic check 
 valve which closes in the event of the gauge glass breaking. 
 
 DURABILITY — Attention is drawn to the fact that in our absorption 
 machine, the only moving part is a small aqua ammonia pump, either a direct- 
 acting steam pump, or a triplex belt-driven single-acting pump, where motive 
 power for operating the same is available. The brine pump is, of course, com- 
 mon to all refrigerating machines using the brine circulating system. The am- 
 monia pump, like the brine pump, can be duplicated at a comparatively small 
 expense, thus reducing to a minimum the chances of accident, owing to break- 
 age of parts. Where it is not desired to duplicate the entire pump, duplicates 
 
 6 
 
of the parts subject to wear can be carried at a trifling expense. Attention is 
 drawn to the large number of plants equipped with single machines, which 
 have worked successfully for a number of years. 
 
 The design, workmanship and material are of the best and the durability 
 of the plant, when the condensing water is derived from the city supply or from 
 a well, cannot be excelled, its only parts subject to corrosion, as in all ice 
 machines of whatever system, being the water coils. 
 
 FUEL ECONOMY — The only source of exhaust steam is the small aqua 
 ammonia pump which bears about the same relation to the whole plant as the 
 boiler feed pump does to the engine of a large power plant; in our system the 
 generator steam is used down to the point where all of its latent heat is 
 expended, down to the point of liquefaction, when it becomes available for 
 return to the boiler. 
 
 WATER CONSUMPTION. — The condensing water, after doing service 
 in the condenser, is passed on to the absorber, being sufficiently cool at the point 
 where the compression machine discards it, to keep the absorber cool, thus lim- 
 iting the water consumption to that of any first class compression machine, no 
 more nor less, when provided with ample condensing surface. For no other 
 absorption machine can such claim be justly made. 
 
 CLAIMS OF EXCELLENCE — We claim for our absorption machine, 
 extreme simplicity, reliability and safety, great economy in the use of fuel and 
 water, as compared with other machines, both of the absorption and compres- 
 sion type. It does not require a high order of skill for successful operation and 
 maintenance. 
 
 These statements are borne out by the testimony of many long time users 
 of the machine ; many of them have favored us with repeated orders, as the 
 growth of their business required additional machinery, and often without com- 
 petition from other builders. 
 
OUR MANUFACTURING- FACILITIES-— Our work shop facilities are 
 ample in every respect, enabling us to get out the heaviest work promptly and 
 economically. We are prepared to build plants from 5 tons to 150 tons refrig- 
 erating capacity, in single units. We command a large force of skilled 
 mechanics, who have for many years been in our employ. Our shipping facili- 
 ties cannot be excelled ensuring us favorable rates of freights in all directions. 
 
 Our engineers and designers have been continuously identified with our 
 system for many years, unlike those of other ice machine builders, who one 
 year advocate one, and the next year an entirely different system. 
 
 RECONSTRUCTION OF EXISTING PLANTS.— We are prepared to 
 repair and enlarge refrigerating machinery of other builders, both of the absorp- 
 tion and compression type. 
 
 We have done considerable work in the direction of combining our brine 
 cooler and ammonia condenser with compression machines of various systems, 
 with the invariable result of materially enlarging the working capacity of those 
 plants, at a comparatively small expenditure of additional power, and increas- 
 ing their fuel economy as well. A list of plants so altered by us, with testi- 
 monials from users as to the benefits derived therefrom, will be sent on 
 application.

 Gentlemen: The 20-ton Pontifex machine built for us in 1884 is continuing 
 to give us good satisfaction. The only change of any consequence that has 
 been made in the plant, was the substitution, about two years ago, of your new 
 ammonia condenser for the old tank condenser, which then showed evidences 
 of corrosion, after having been used nearly ten years.

 Gentlemen : I take pleasure in testifying to the excellent work clone by 
 the two twenty-ton Pontifex machines in our storehouses during nearly two 
 years of constant use. 
 
 The temperature in our freezing rooms has been, on an average, fifteen 
 degrees above zero, and this has been maintained without difficulty. 
 
 Since the 15th of January, 1887, the machines have been run continuously, 
 and in my judgment they cannot be equalled by any other now in the market. 
 As regards coal consumption they are very economical

 first place. We have added 40 per cent, to our storage capacity by building 
 the three additional stories for which our warehouse was originally planned. 
 We are obtaining to-day the same low brine temperatures which we have always 
 deemed necessary for successfully conducting the freezing and cold storage 
 business. We shall be pleased to exhibit our plant, of which we are justly 
 proud, for the inspection of all parties who may be interested in seeing first

 Gentlemen: We have been operating the two 25-ton Pontifex-Hendrick 
 Ice Making Machines continuously during the past Summer, and cannot speak 
 too highly of their work or economy ; they have never failed us in a very 
 busy season, and we feel that they are thoroughly reliable. 
 
 The ice, both from the plate and the can bath, is the finest in Los Angeles, 
 and captures the trade wherever it competes. Our average daily output, during 
 the months of July and August, was thirty-six tons ; besides this work, we 
 cooled by aid of your Pontifex Brine Cooler, one hundred and fifty thousand 
 cubic feet of space, of which one hundred thousand feet were maintained at 
 freezing temperatures of from 15 0 to 25 0 Fahr., and forty thousand at cold- 
 storage temperatures of 32 0 Fahr. and upward. Our fuel and water consump- 
 tion is small as compared with that of other ice factories in Southern California ; 
 our condensing water temperature is 70° Fahr. nearly all the year round. We 
 shall be glad to give any further particulars to parties who may make inquiry 
 of us as to the performance of your machinery. 
 
 Wishing you continued success in your business, we are, 
 
 Yours truly,

 Dear Sirs: We beg to say that in 1S91 we purchased from you a 30-ton 
 Hendrick-Pontifex Ice Machine, which has given us excellent service, doing 
 much greater work than the indicated tonnage. The machine was erected in 
 June, 1891, and ran continuously until April 1, 1894, without break or stop- 
 page of any kind. We thought so highly of this make of machine that when 
 we fitted up our present warehouse last year we bought another Pontifex 
 machine, and the two are now running side by side, and we are well pleased 
 with results. We cheerfully recommend the Pontifex machine to intending 
 purchasers. Yours very truly,

 formance of the 20-ton refrigerating machine during the summer of iSg6. 
 
 We piped two more rooms containing 32,000 cubic feet of space; but the 
 machine has carried the additional capacity successfully. 
 
 With our indirect system of cooling, the eggs have always come out at the 
 end of the season in a condition highly satisfactory to the dealers. 
 
 Very truly yours,

 Dear Sir: We take pleasure in recommending your machine to any one 
 requiring artificial refrigeration. We have run one of your machines for the 
 past season, and would say that the guarantee which you made has been sus- 
 tained- while the guarantee for the amount of coal, etc., to be used has also 
 come within the figures named by you in your bid. 
 
 We are entirely satisfied, as will be shown from the fact that we ordered 
 our second machine after having run the first one for nearly a year. 
 
 Wishing you success, we are, yours truly,

 Note. — In 1897, a third machine of 100 tons capacity was erected, a new warehouse having 
 been built. This company is now cooling additionally the storage rooms of the Buffalo Fish 
 Company which is freezing about 20 tons daily during the season, the freezing plant being located 
 about 500 feet from the engine room. It is also maintaining a brine circulating system for the con- 
 venience of about fifteen produce commission dealers in the immediate vicinity of the warehouse.

 Gentlemen: We are glad to be able to say that the 15-ton refrigerating 
 machine which you placed in our fruit storage house at Spencerport, N. Y., has 
 proven a satisfactory investment. 
 
 We have done remarkably well, considering the fact that until very recently 
 we have had only eight gallons of condensing water per minute from our well, 
 and that we have no other source of water supply, the water being cooled for 
 continuous use by sprinkling it over the slated roof of our cold storage house. 
 When the weather is warm and the relative humidity high, this does not make 
 a very efficient cooling arrangement ; nevertheless, the plant has done well and 
 given us all of the refrigeration required. 
 
 My man in charge has no difficulty in handling the machine, although he 
 knew little or nothing about steam machinery before he took hold, and, of 
 course, nothing about ice machinery. 
 
 Yours truly,

 Gentlemen : We take pleasure in saying that the 50-ton refrigerating 
 machine which you built for our Manhattan Market plant has done its work in 
 a very satisfactory manner. Our tenants, seven of the leading wholesale 
 dressed beef companies, are very exacting in their refrigerating requirements ; 
 but we have given them service entirely satisfactory, both on the brine system 
 and the direct expansion system, with which one of the houses is cooled. 
 
 The fact that for our new cold storage warehouse and Central Station plant 
 at West and Horatio streets, we again adopted the absorption system, is evidence 
 of our belief that for low temperature work this is to be preferred to the com- 
 pression system.

 Gentlemen : After having had three years of experience in the use of your 
 refrigerating system, in our fruit storage house at Spencerport, N. Y., under 
 adverse circumstances, with, however, satisfactory results, it did not require 
 much investigation on our part to decide that your machine would meet equally 
 well the requirements of our New York warehouse, which we fitted up last 
 year. In fact, we adopted it without hesitation, and we are well pleased with 
 our decision. 
 
 The continued use of power pumps, both here and at Spencerport, convinces 
 us that with these pumps your refrigerating system is as nearly perfect in its 
 operation as can be expected, requiring very little attention.

 Dear Sirs : I n compliance with your request, would state that for the past three 
 years we have been refrigerating our sharp freezers and cold storage rooms by 
 the brine system from your absorption refrigerating machine. The service ren - 
 dered has been very satisfactory. We have had no difficulty in freezing our fish 
 in twelve to twenty-four hours and maintaining the storage rooms at any de 
 sired point above zero Fahr The temperatures are maintained vvtth very 
 little variation.

 Gentlemen : We send you the photographs to-day, one of the interior and 
 the other of the outside, as requested. 
 
 Would say that, as far as the machine is concerned, we are perfectly satis- 
 fied with it ; it is doing the work easily and with very little care and attention, 
 and the plant is certainly as finely and substantially built as a man could ask 
 for. Why anybody wishes to run a compression machine now-a-days with any- 
 thing as simple to take care of, I cannot see. You know I looked into the 
 matter very thoroughly and bought your machinery regardless of other people’s 
 opinions and preferences. Nine out of ten I talked with, said the absorption 
 machine was no good, and advised me not to look at it, that I would be sorry 
 
 from the day I bought it. Of course, we have not had it a great length of time 
 
 yet, but I do not see any reason why it should not do as well one year as 
 
 another, and all I can say is, I am very glad that I had mind enough of my own 
 
 to buy what I considered was the best machine in the market. 
 
 If you ever wish to refer to me or to have anybody see my plant, I will do 
 my best for you, both for reference and showing them the plant.

THE HENDRICK BRINE COOLER 
 
 FOR 
 
 ICE AND REFRIGERATING MACHINES. 
 
 AMMONIA COMPRESSION SYSTEM. 
 
 The attention of users of ammonia compression machines of all systems 
 is invited to the merits of the brine cooler, or refrigerator, originally designed 
 for use in connection with the Hendrick Ammonia Machine, but latterly intro- 
 duced by us, with great success, in connection with ammonia compressors. 
 
 As compared with the ordinary method of direct ammonia expansion in 
 coils submerged in the brine tank, we claim for it and are prepared to guaran- 
 tee its ability to add from io to 25 per cent, to the working capacity of the 
 ammonia compressor, with a material reduction in steam consumption; while 
 the opportunities for ammonia leakage, owing to the absence of pipe joints, 
 which are exposed to the action of brine, are reduced to a minimum. 
 
 Our brine cooler consists of a heavy cast-iron shell, standing upon 
 columns, filled with spiral pipe coils, the tails of which project through the 
 heads of the shell; the liquid anhydrous ammonia is expanded in the shell, 
 entering at the expansion valve near the bottom of the cooler, and leaving it 
 after having performed its work, near the top, where the suction pipe leading 
 to the ammonia compressor connects The brine is circulated through two or 
 more spiral coils, welded continuously from end to end, entering at the top 
 and leaving at the bottom of the cooler. The brine in its downward passage 
 through the coils loses in temperature from 5 to 15 degrees, according to the 
 rapidity of flow; the rapid motion of the brine and the consequent prompt 
 exchange of cold between the expanding ammonia and the circulating brine, 
 makes every portion of the cooler coils thoroughly effective. The whole 
 apparatus is therefore exceedingly compact as compared with the usual 
 
 59 
 
brine tank construction, as the amount of coil surface is but a fraction of that 
 ordinarily used for producing a similar cooling effect. The cooler is usually 
 located in the engine-room, close to the ammonia compressor, and hence, is 
 constantly under the eye of the engineer; the ammonia does not, therefore, 
 leave the engine-room at all, the work of cooling being produced entirely in 
 this apparatus. The brine tank in this case simply becomes a cold brine 
 storage tank, which can be located where most convenient, either in the 
 engine-room or in a refrigerated room, and can be of any size and shape 
 which local circumstances may demand. 
 
 As the expansion of the anhydrous ammonia occurs in the shell and 
 around the coils, a portion of the liquid lying in the bottom of the shell, there 
 is no loss of back pressure, due to the friction in the ammonia coils, as in the 
 system of ammonia expansion in coils submerged in the brine tank. We are 
 therefore enabled to carry, for a given brine temperature, a back pressure 
 greater by from five to ten pounds than in the old system of expansion, with 
 the result of increasing the working capacity of the plant proportionately. 
 
 All coils are continuous from end to end, being of welded extra heavy 
 pipe; they are subject to ammonia pressure from without instead of from 
 within, and hence, are not as liable to burst. 
 
 To those who contemplate making repairs to submerged ammonia coils, 
 the Hendrick Brine Cooler is presented as a ready means of making the 
 change, at comparatively small expense, and with a minimum of trouble; the 
 brine tank need not be disturbed at all; the ammonia coils can either be dis- 
 connected and left in place or entirely removed, and the ammonia suction and 
 feed lines only require to be changed.

 Gentlemen In reply to your Inquiry as to the working of your 75-ton 
 brine cooler attached to our 85-ton ‘ Buffalo” machine at our Greenwich Street 
 plant, we would say, it is giving entire satisfaction 
 
 From our experience the old style of expansion in brine tank coils is not to 
 be considered with it in efficiency. 
 
 \Ye contemplated using your cooler in connection with the old compressor 
 before enlarged but find it capable of handling all the liquid ammonia the 
 enlarged compressor can furnish without freezing back,” which formerly gave 
 us trouble when the machine was run to its full capacity. 
 
 Yours truly,

 Gentlemen: Replying to your inquiry with reference to the Brine Cooler 
 which we purchased from you, we have had it in operation since the 1st of 
 April, and thus far are more than pleased with the result. We have it work- 
 ing in connection with our 35 ton Delavergne machine, and it has demon- 
 strated its superiority over any other method of ammonia expansion. It is 
 certainly very easy to operate, requires but little room, and is moreover of an 
 attractive appearance, being an ornament to any machine room. 
 
 We think, furthermore, that it adds considerably to the refrigerating 
 capacity of a compression machine; we find that we are enabled to carry from 
 7 to 9 pounds higher back pressure with the same brine temperature, than we 
 should be with the ordinary system of brine cooling. As the writer is a 
 strong advocate of the system of brine circulation for cold storage purposes, 
 he does not hesitate to recommend your Brine Cooler most strongly, whether 
 operated in connection with a compression or an absorption machine. 
 
 Yours very truly, 
 
 SYRACUSE COLD STORAGE AND WAREHOUSE CO.,

 the machine was used in connection with a direct ammonia system.

 say that the brine cooler which you furnished us in March last has fully 
 realized our anticipations, and we feel confident, from such tests as we have 
 been able to make thus far, that the cooler exceeds its contract capacity. 
 
 We regard your system as a decided improvement over any form of brine 
 tank construction with which we are familiar. 
 
 We are also glad to bear testimony to the prompt and satisfactory manner 
 in which you executed your contract in a comparatively brief time.

 Gentlemen: In November, 1895, after having used your ammonia condenser 
 with good results for about one year, we adopted your brine cooler system in 
 connection with the ammonia compression machine at our freezing warehouse, 
 abandoning our direct expansion system, but using the same circulating pipes. 
 We find that it has given us more uniform temperatures than the direct ammonia 
 system. It has also effected quite a saving in fuel, for we succeeded in 
 reducing the annual coal consumption from 385 tons in 1895, to 275 tons in 1896. 
 Furthermore, we added at this time about 6,868 cubic feet of space, devoted, as is 
 our entire warehouse, to the freezing of poultry and game, carrying our tempera- 
 tures fully as low, if not lower than heretofore and certainly very much more 
 uniformly. We are much pleased with the change that has been made, and 
 you can, at any time, refer intending purchasers to us.
