Benicia, Calif.--Richmond, Calif. For Expansion Joints--See Page 312 INSTANTANEOUS HEATERS Adsco instantaneous heaters are made in a large variety of types, including the simple U-bend instantaneous shown above, which is used to heat water for showers, dishwashers, laundries, and other purposes. These heaters are also used as Convertors for furnishing hot water to space heating systems. Many straight-tube, float-head units are used as closed feed-water heaters, boiler blow-down heaters, and for vari ous uses in the process industries. STORAGE HEATERS Adsco storage heaters are built in ac cordance with the ASME code for work ing pressures desired. Tanks are made of flange-quality steel, nickel-clad or stainless-clad steel, or copper silicon alloy. Where alloy tanks are used, tube sheets are of non-corrosive metal, so that service water does not come in contact with any ferrous parts. Steel tanks can be lined with Adsco Phenolic 6-2 or Adscote bitumastic to prevent corrosion. All units are equipped with cold-water spreaders. Manholes are heavily rein forced. Copper U-bend heating element is easily removed for cleaning. TANK SUCTION HEATERS Adsco tank suction heaters reduce vis cosity of heavy oil or other fluids so they can be pumped economically. Instead of employing pipe coils on the bottom of the tank to raise the temperature of all the liquid, only the liquid to be pumped is heated. Steam waste is eliminated. These heaters are furnished with nozzle for welding into storage tanks or with flange for bolting to existing flanged nozzle. POOL HEATERS These heaters, in straight tube or U-bend design, heat large volumes of water through a narrow temperature range. They are suitable for heating water for swimming pools, as well as for space heating systems and process work. OIL PRE-HEATERS Adsco oil pre-heaters help obtain the highest performance from fuel oil by heating it properly for complete com bustion in the burner. In many cases, the work done by oil pre-heaters permits the use of heavier grade, less costly fuel oil. These heaters frequently are used with Adsco tank suction heaters, the two units making an efficient team. FLOAT-HEAD HEATERS These heaters are built to customers' specifications in all sizes, of either verti cal or horizontal design with removable or non-removable tube bundle of the straight-tube type which permits of easy cleaning. They are commonly used as boiler blow-down heaters, feed water heaters, and as space heaters in large heating systems. 400 Healing Systems Aerco Corporation Paris Avenue, P.O. Box 248 Northvale, N. J. AERCO's Controlled "HTR" (Heat Transfer Rate) Heat Exchanger is a Compact Storage Water Heater featuring an Internal Compensator which: Anticipates changes in required steam flow before the actual heat transfer takes place. Meters the steam flow accurately in \ direct proportion with load. Prevents surges in steam flow, elimi nating need for large storage. . Maintains ACCURATE control of out let water temperature. Prevents OVERRIDE of outlet tem perature on sudden interruption of water flow. For UNIFORMLY VARYING LOADS (i.e. Hospital General Water Supply), the ability of the above heater to prevent steam flow surges ELIMINATES the need for large STORAGE. For NON-UNIFORMLY VARYING LOADS or periodic high peak flows and low average demands (i.e. Small Commercial Laundry), the AERCO COMPACT STOR AGE WATER HEATER with an Accumulator and Recirculating Pump (as shown in Figure 2) gives a low cost combination which also permits: Minimum storage volume for peak de mands. . Minimum steam input for required load. " Accurate controlled outlet water tem perature under all load conditions. Fwttre t--Aerco Compact Storage Water Heater in Mmtmoiwn mtk Accumulator and Recirculating CONSTRUCTION Shell fabricated to ASME Code Standards, of Flange Quality Steel with plastic or copper lining. Shell ends Cast-iron or Bronze. Internal parts of Copper or Brass. Tested for 125 psig operating pressure. Capacities, 300 to 25,000 gph. OPERATION Cold water enters top, flows down through the Compensator, then up across steam coils to discharge at top. Steam feeds into coils through Steam Riser and leaves through Condensate Return. Compensator anticipates and controls heat transfer rate by sensing changes in flow or incoming temperature before water passes over the heating coils. It accom plishes this by causing variations of temperature to occur at the Regulator bulb which are definitely related to changes in flow and incoming temperature as well as the final temperature.
