Shell and Tube Heat Exchangers & Unfired Boilers | Boilersupplies Bell & Gossett Heat Exchangers | Boilersupplies.com Bell & Gossett Water to Water U-Tube Heat Exchanger
Bell & Gossett Water to Water (WU) complete heat exchangers. 2 and 4 pass units, 4" nominal thru 10" nominal in our cataloge. Larger units available upon request.B & G Types "WU" Heat Exchangers are of the shell and tube type. The tube bundle is of "U" bend construction with tube ends expanded into a stationary tube sheet. This construction permits ample expansion or contraction for wide temperature variations.Standard "WU" Heat Exchangers are construced according to ASME requirements for pressure and temperatures.
• Removable bundle for ease of inspection and replacement.
• This design allows for differential thermal expansion between shell an tubes as well as between individual tubes.
• The result is a heat exchanger capable of withstanding thermal shock.
• The bundle design and tube layout allow for the maximum heat transfer surface area per given shell size.
• The SU/WU exchangers are also available with Diamondback double wall tube construction and heavy duty construction for high temperature applications as well as tank heater designs.
Materials:
Standard Copper (tubes), carbon steel (shell, tube sheet, baffles) Optional Brass (tubes, tube sheets, baffles), bronze (heads), stainless steel (tubes, tube sheets, heads, shells, baffles), 90/10 Cu-Ni (tubes)
B & G Type "WU" Heat Exchangers are of the shell and tube type. The tube bundle is of "U" bend construction with tube ends expanded into a stationary tube sheet. This construction permits ample expansion or contraction for wide temperature variations. A fluid entering the tubes is heated by steam condensing in the single pass shell. Tube spacers properly support and space each tube for maximum efficiency in steam condensation and drainage.
