BASCO (AEW) HEAT EXCHANGERS
BASCOTYPE “OP”(AEW) HEATEXCHANGERS .world leaders in heat transfer technology
Standard Heat Exchanger Designs Deliver CostEffective PerformanceFirst introduced in 1962, the Basco OP design has proven to bethe preferred TEMA Type AEW Shell & Tube Heat Exchanger in themarket. The OP, or “O” Ring Protected design, is available in single ortwo pass. The Basco design features removable tube bundle, nozzlelocation flexibility and a unique threaded O-ring retainer that permitsremoval of the reversing bonnet without disturbing the piping ordraining the shellside fluid. Then removal of the channel cover permitsfull inspection and cleaning of the tube side.Quality, Value andPerformance.An API Heat TransferTraditionFor over 60 years, originalequipment manufacturersand aftermarket providershave looked to API HeatTransfer for a wide varietyof heat transfer products.The Basco Type “OP”optimizes standardizedcomponents in a highlyconfigurable design for awide variety of processapplications.The unique O-ring retainer prevents the possibility of over-tighteningthe bolts and damaging the O-rings. This same retainer incorporatestwo “tell-tale” holes that warn the operator of any fluid leaks fromeither the shell or tube side.API Basco has standardized this design using stock components. Thismeans the solution to your cooling requirement is closer than ever.QualityAt API Heat Transfer, quality begins with properly applying the design tothe process conditions, ensuring the design of the heat exchanger ismechanically correct for the service and applicable code requirementsand finally manufacturing the unit to strict quality standards using onlyhigh quality code materials. The Basco OP has a proven track recordfor quality and service. Knowledgeable Application Engineers. Demand Flow Technology (DFT) to reduce lead-times, increaseflexibility, improve efficiency, ensure consistently high quality andreduce cost. ASME, TEMA, API 614, ABS, USCG and other constructions available.ValueValue means obtaining the best features and performance required tomeet a particular need at the best price and lead-time. API Heat Transferknows this and has designed the Basco OP to exceed your expectations. Unique double O-ring sealed floating tube sheet provides leakdetection and eliminates the possibility of over-tightening bolts,avoiding damage to the O-rings. Dome type shell nozzles available for higher flow rates at lowerpressure drops. Highly efficient heat transfer with either bare or lo-fin tubes due totight tolerances with baffles that minimizes fluid by-pass. Flexible configurations all manufactured from stock componentsmeans proven designs in the shortest possible lead-time.PerformanceThe wide range of OP configurations available have made these durableperformers the first choice for a variety of cooling applications including: Compressed air Jacket water Steam or gas turbine oil Gland seal condensers Hydraulic oil Condensate cooling Lube oil Ship board and marine Bearing waterengines– –
Quality materials machined andassembled by an experienced,dedicated workforce result inconsistently high quality finishedproductsAPI Heat Transfer utilizes modern, high precisionmachining centers to convert raw materials intocomponent parts. Then experienced skilled weldersand assemblers transform these components intosuperior quality finished heat exchangers. Highcapacity oil flush stations, in-house shot blasting,controlled final paint application and even value-addedpackaging with other components such as valves andfans result in a heat exchanger fit for purpose andready to provide years of troublefree service.Certified Demand FlowProduction Methods andISO QualityAPI Heat Transfer has fully embracedthe superior quality, improved workflow and cost controls inherent inDemand Flow Technology (DFT)and Lean Manufacturing. Productsare made “on-demand” fromcomponents and in-line supportmachining centers. With DFT, nonvalue procedures are eliminated,inventory costs are reduced andquality is maintained and verified atevery phase of the assembly. APIHeat Transfer also has ISO 9001certification assuring world-classmanufacturing methods and fullaccountability to our customers.DFT, Lean Manufacturing andISO 9001 result in reduced cycletimes, increased flexibility, higherefficiencies, consistently high quality, and .MORE VALUE FOR OUR CUSTOMERS!As one of the largest USmanufacturers of industrialheat exchangers, API HeatTransfer’s investment inmachinery and people,quality procedures andmanufacturing processes,has proven to be the rightstrategy to earn our customers’business over and over again.– –
“OP” Exchanger Design TechnologyBasco Type “OP“ Heat ExchangerOffers cost-effective performance by utilizing standardized designs and stock components.TUBESHEETSAvailable in Carbon Steel, StainlessSteel, NRB, 90/10 or 70/30 CuNi orTitanium tubesheets.TUBESAvailable in Carbon Steel, Copper, 90/10 or 70/30CuNi, Stainless Steel, Admiralty or Titanium. Tubesare roller expanded. Seal welding and groovingavailable. Tubes are available with lo-fin enhancements.SUPPORTSMovable, fabricated with rod to 16”; fixed cradlesover 16” diameter.CHANNELSSteel or Cast IronSHELLSAvailable in Steel and Stainless Steel. Minimumclearances between shell and baffles reduceby-pass and maximize heat transfer.BAFFLESPrecision punched baffles assure effective circulationby providing minimum clearances between thetubes and tube holes. Baffle cuts and spacing foreach diameter are consistent with best practices.Basco’s Double “O” RingSeal PreotectionPermits tube bundle to expandand contract without strain orintermixing of shell and tubesidefluids. O-Rings retain compressionand are unaffected by vibration andtemperature changes. Telltale holesreveal any leakage.Special FeatureThe unique construction of the Basco OP permits inspection andmaintenance of the tubeside without draining the shellside or disturbingthe piping.– –
