In this case, the oil temperature changemust be determined so that the actual oil leaving temperature can be found.Calculate the oil temperature change (Oil #T) with this formula:Caution: Incorrect installation can cause this product to fail prematurely, causing the shell side andtube side fluids to intermix.To calculate the oil leaving temperature from the cooler, use this formula:One PassOil #T (BTUs/HR)/GPM Oil Flow x 210).Oil Leaving Temperature Oil Entering Temperature - Oil #T.This formula may also be used in any application where the only temperatureavailable is the entering oil temperature.Oil Pressure Drop: Most systems can tolerate a pressure drop through theheat exchanger of 20 to 30 PSI. Excessive pressure drop should be avoided.Care should be taken to limit pressure drop to 5 PSI or less for case drainapplications where high back pressure may damage the pump shaft seals.Piping DiagramOUTINHOT FLUIDINOUTCOOLINGWATERTwo and Four PassHOT FLUID(May be reversed)COOLINGWATERSpecific applications may have different piping arrangements.

Shell & Tube Recommendations0916InstallationThe satisfactory use of this heat exchange equipment is dependent uponprecautions which must be taken at the time of the installation.RecommendationsReplace gaskets when removing end castings. It is recommended thatgaskets be soaked in oil to prevent corrosion and ensure a tight seal.1. Connect and circulate the hot fluid in the shell side (over small tubes)and the cooling water in the tube side (inside small tubes). Note pipingdiagrams.Salt water should not be used in standard models. Use salt water in specialmodels having 90/10 copper-nickel tubes, tube sheets*, bronze bonnets andzinc anodes on the tube side. Brackish water or other corrosive fluids mayrequire special materials of construction.2. I f an automatic water regulating valve is used, place it on the INLETconnection of the cooler. Arrange the water outlet piping so that theexchanger remains flooded with water, but at little or no pressure.The temperature probe is placed in the hydraulic reservoir to sense asystem temperature rise. Write the factory for water regulating valverecommendations.3. T here are normally no restrictions as to how this cooler may be mounted.The only limitation regarding the mounting of this equipment is thepossibility of having to drain either the water or the oil chambers after thecooler has been installed. Both fluid drain plugs should be located on thebottom of the cooler to accomplish the draining of the fluids. Drains areon most models.4. It is possible to protect your cooler from high flow and pressure surges ofhot fluid by installing a fast-acting relief valve in the inlet line to the cooler.5. I t is recommended that water strainers be installed ahead of this coolerwhen the source of cooling water is from other than a municipal watersupply. Dirt and debris can plug the water passages very quickly,rendering the cooler ineffective. Write the factory for water strainerrecommendations.6. F ixed bundle heat exchangers are generally not recommended for steamservice. For steam applications, a floating bundle exchanger is required.Note: When installing floating bundle unit, secure one end firmly andopposite end loosely to allow bundle to expand and contract. Consultfactory for selection assistance.7. P iping must be properly supported to prevent excess strain on the heatexchanger ports. If excessive vibration is present, the use of shockabsorbing mounts and flexible connectors is recommended.ServiceEach heat exchanger has been cleaned at the factory and should not requirefurther treatment. It may be well to inspect the unit to be sure that dirt orforeign matter has not entered the unit during shipment. The heat exchangershould be mounted firmly in place with pipe connections tight.CautionIf sealant tape is used on pipe threads, the degree of resistance betweenmating parts is less, and there is a greater chance for cracking the heatexchanger castings. Do not overtighten. When storing the unit, be sure tokeep the oil and water ports sealed. If storage continues into cold wintermonths, the water chamber must be drained to prevent damage by freezing.Performance information should be noted and recorded on newly installedunits so that any reduction in effectiveness can be detected. Any loss inefficiency can normally be traced to an accumulation of oil sludge, orwater scale.When zinc anodes are used for a particular application, they should beinspected two weeks after initial startup.At this time, by visual inspection of the anode, determination of futureinspection intervals can be made, based on the actual corrosion rate ofthe zinc metal.The zinc anodes must be replaced when 70% of the zinc volume hasbeen consumed.It may be necessary to drain the water chambers of the exchanger to protectit from damage by freezing temperatures. Drains are provided in moststandard models.The oil chamber of the exchanger may become filled with sludgeaccumulation and require cleaning. It is recommended that the unit beflooded with a commercial solvent and left to soak for one-half hour.Backflowing with the solvent or regular oil will remove most sludge.Repeated soaking and backflowing may be required, depending on thedegree of sludge buildup.It may be necessary to clean the inside of the cooling tubes to remove anycontamination and/or scale buildup. It is recommended that a fifty-fiftypercent solution of inhibited muriatic acid and water may be used. For severeproblems, the use of a brush through the tubes may be of some help. Besure to use a soft bristled brush to prevent scouring the tube surface causingaccelerated corrosion. Upon completion of cleaning, be certain that allchemicals are removed from the shellside and the tubeside before the heatexchanger is placed into service.When ordering replacement parts or making an inquiry regarding service,mention model number, serial number, and the original purchase order number.*Available on HC/SSC/SSCA Series models only.
