For almost 40 years askarel transformers have served the commercial, industrial and utility fields faithfully with safety, economy and reliability. They are built to exact specifications by all major electrical equipment manufacturers.;/; Mineral oil transformers can catch fire. When used in confined or populated areas/they require fire walls, vaults, and sprinkling systems; or they must be lo cated at a more remote point requiring long expensive low-voltage lines. Open dry type transformers are limited in flexibility of location. Supplemental installation costs usually run much higher than with askarel units, especially if sound-deadening or enclosing from atmospheric con tamination and moisture is required. They are less de pendable than askarel units because they are affected by corrosive atmospheric conditions. Due to the na ture of open dry type units, they can require a great deal of maintenance; have a high noise level, and are expensive to operate because of higher load losses and frequent maintenance requirements. Askarel units deliver a steady power flow year after year, offering lower operating and maintenance costs, quietness and dependability. They are fire-resistant and allow you to place them where YOU want them placed, right at the point of use if you choose. Think of the savings in installation alone! Askarel will not oxidize or sludge; remains chemically stable when subjected to elevated temperatures and will not corrode metals. c V o o Monsanto has manufactured and supplied askarel fluids since the askarel type trans former was first introduced. The askarel fluid insulation is supplied under various trademarks such as "PYRANOL" (General Electric); '`INERTEEN" (Westinghouse); "CHLOREXTOl" (Allis-Chalmers); "NOFLAMOL" (Wagner Electric). Many other manufacturers such as l-T-E use the gen eric name, askarel. In all cases, Monsanto makes the askarel fluid for these trans formers.

TYPICAL EXAMPLE 1,000 KVA, 3 phase, 60 cycle, 13,800 to 480 Y volts. Transformer first cost assumed about $8,500. UNIT COIL LOSS CORE LOSS (at 100% Load) (Watts) (Watts) Incorporate your own figures in the fol lowing example and prove this point to yourself. The figures shown assume the same first cost of an askarel transform er and an open dry type unit. (Askarel transformers are now quoted at the same price as 150C. open dry types.) Open Dry Type Askarel Unit 4,200 2,900 18,500 12,500 ; (A) Based on a 75% load factor, coil losses are ap| proximately as follows: ; Open Dry Type.. 18,500 x (.75)2 = 10,400 watts ; Askarel Type .. .12,500 x (.75)2 = 7,000 watts ; Coil Loss Difference.. .3,400 watts ; Total Core and Coil Loss Difference ; in favor of Askarel.................. ..........4,700 watts Based on an 8,700 hour year operation: i 4,700 x 8,700 = 41,000 KWHR (Approx.) Assuming power cost is $0,015 per KWHR: the savings each year is $615.00 ... or the Askarel Transformer first cost is paid for in about 10 years.* 'This annual savings compounded al 6% per year. STLCOPCB4074253 askarel fire-resistant transformers offer easy maintenance '' \\ \ v % LOW MAINTENANCE MEANS GREATER SAVINGS IN TIME AND MONEY! Askarel transformers are easiest to maintain. Proper sealing of modern as karel transformers has banished the threat of water contamination, the arch enemy of all transformers. No need to periodically shut down the system for cleaning . . . the askarel fluid is sealed against moisture and atmospheric con tamination. There are no exposed coil cores to gather dust and lint that must be periodically cleaned as with the open dry units. Other than an occasional fluid test, you install them and leave 'em alone.

You do not have to wait un til other phases of construction are com pleted. No added expenses are neces sary to protect it from contamination, subdue the sound level or run expensive lines from distant locations. You place it where your system dictates, not where the transformer dictates. The start-up costs for askarel transform ers are almost nil. Because they are sealed, there is no expensive clean-up and drying out required prior to starting. Just bring it in, hook it up and start op erating. This alone offers a big savings. askarel transformers offer fire safety ASKAREL FLUIDS ARE FIRE-RESISTANT! The fluid is fire-resistant and does not support combustion. Just as important, the fluid will not carry or add burning oil hazards to fires which may start from other causes. The liquid does not de teriorate when exposed to heat or hot metal; it does not decompose over long periods of time. Municipal codes also tend to favor askarel transformer instal lations over other types. DSW 322604 STLCOPCB4074255 askarel fire-resistant transformers are quieter CHECK THE STANDARDS! Open dry types produce a higher noise level, requiring expensive sound-sup pressing additions or location far from the point of power usage. Wherever the sound level is a factor, askarel trans formers rate quieter than comparable open dry type units ... 3 to 6 decibels is a major reduction in discernable sound level. askarel fire-resistant transformers are reliable THERE ARE MANY EXAMPLES OF OVER 30 YEARS OF ! TROUBLE-FREE OPERATION! : A properly designed and installed aska- : rel transformer will give long years of ' trouble-free service . . . many in opera ; tion for over 30 years. This fact has been ; proven in installations throughout the > world. Even longer life can now be ex ; pected due to more modern design } practices in sealing out moisture and ' ....... . eliminating leaks. DSW 322605 STLCOPCB4074256 askarel fluids maintain high dielectric strengths The most significant and reliable meas urement of transformer askarel electrical performance is its dielectric strength. Askarel will maintain its high dielectric strength unless there is a significant amount of moisture contamination or breakdown of the fluid from an unusually severe electrical discharge. Askarel fluids are manufactured by Mon santo and shipped to transformer mak ers all over the world. They are manu factured and quality checked for con sistency and properly packaged for ship-q ment. > J Transformer makers, utilities, and speci tiers, in turn, handle askarel fluids under standard normal good housekeeping < ' and personal precautions used with -___ other industrial products.
