SENTRY SPIRAL TUBE Heat Exchangers Solid & Powder Steam & Water A spiral tube heat exchanger is a coil assembly fitted in a compact shell that optimizes heat transfer efficiency and space. Every Sentry® spiral assembly has welded tube to manifold joints for durability and strength. The coil assembly is welded to a head and fitted in a compact shell. The spaces or gaps between the coils of the spiral tube bundle become the shell side flow path. Typical applications include: Pump seal coolers Sample coolers Inter/after coolers Acid heaters/coolers Instant hot water heaters Process condensers MODELS Varied BENEFITS The spiral shape of the flow for the tubeside and shellside fluids creates centrifugal force and secondary circulating flow that enhances the heat transfer on both sides in a true counterflow arrangement. Since there are a variety of multiple parallel tube configurations (diameter, number and length), efficiency is not compromised by limited shell diameter sizes as it can be with shell and tube designs. The profile of a spiral is compact and fits in a smaller footprint than a shell and tube design. Since the tube bundle is coiled, space requirements for tube bundle removal are significantly reduced. When exotic material is required, a spiral tube heat exchanger minimizes the material used since manifolds replace the channels, heads and tubesheets of a conventional shell and tube design. The shell side is usually smaller than a comparable shell and tube design and there are no requirements for tube supports or pass dividers. FEATURES Flow rates to 100 GPM (378 LPM) Sample conditions up to 5000 psi (345 bar) and up to 1000° F (540° C) Optimal design for corrosive fluid/ gases Vapor condensing/gas stripping capabilities High flow in a small footprint Highly resistant to thermal and hydraulic shock Bolted or all welded shell Numerous flow path and connection configurations Compac
