Our extensive line of Basco Type HT and AHT heat exchangers offer 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.
Our 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.
The 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.
