Basco / Whitlock Hub-Design Heat Exchanger

API’s extensive line of Basco/Whitlock HT, AHT, and 550 hub-style heat exchangers offers the benefits of non-ferrous construction in a highly standardized design for maximum flexibility at minimum cost. Hub design advantages include increased corrosion resistance, maximum obtainment of tube quantity in a given diameter for better efficiency, and lower entrance velocity and pressure drop as a result of the dome shell nozzle.

Cast Iron, Bronze or Stainless Steel End Bonnets. Tubes roller expanded and flush with tube sheets. Holes are drilled and reamed. Seal welding available on some models. Tubes available in copper, admiralty, copper-nickel, stainless steel or special materials. Shell ports available in NPT, SAE or threaded O-ring designs. Hubs can be rotated in 90 degree increments. Generous entrance dome provides superior flow distribution and reduced pressure drop. One, Two or Four Pass Models are available. Removable mounting feet with slotted holes can be reversed or rotated for quick, easy installation. Precision cut baffles provide minimum clearances for controlled flow. Most models feature collared design for excellent rube support. Shells are available in brass 316 stainless steel. Models available in straight and fixed or removable U-tube designs.
Type HT heat exchangers have been in production since 1965. Standard HT models feature low-cost, non-ferrous construction with brass shell, brass tubesheet and straight copper tubes. End bonnets are cast iron. Numerous options including special materials and nozzle orientation are available.

Type AHT heat exchangers feature all 316 Stainless Steel construction in a wide variety of configurations. Modified units are suitable for critical service where ultra-clean conditions are paramount. Options include seal welding of tube to tube sheet joints and polished surfaces for pharmaceutical and food processing applications.

Type HTR and AHTR feature a removable tube bundle design allowing shellside cleaning and bundle replacement, rare in a low cost small diameter design where tubesheets are typically fixed. Available in non-ferrous or stainless designs.

Type 550 Heat Exchangers offers users of competitive brands the ability to realize better overall value in their heat exchanger purchases. Engineered and manufactured to be dimensionally interchangeable with certain ITT Standard and Thermal Transfer models, Basco/Whitlock 550 models feature collared baffles that minimize fluid by-pass for maximum thermal performance. Spare parts, including bonnets and gaskets, are also interchangeable.
