Spiral Tube Spiral tube sample coolers provide high efficiency in a small footprint for high pressure and severe service applications. It consists of a dual manifold multi-tube spiral assembly inserted into a shell, where two paths are created for full counterflow heat transfer. Up to 40% more efficient than a typical shell and tube heat exchanger Pressure ratings up to 5000 psi (345 bar) Temperature ratings up to 1000°F (540°C) Compact and lightweight Highly resistant to thermal and pressure shock Standard tube-side material is 316 Stainless Steel; shell-side is carbon steel; exotic materials available for both sides Bolted or welded shell construction Heat transfer areas up to 150 ft2 (14 m2) ASME "U" stamp available
