•Coils manufactured from finned seamless tube
•Typical tube material is Gr106 B CS, P11 or P22
•Typical tube material is CS or TP409
•Helical layout promotes turbulent flow which increases heat transfer rate.
•Coil is heat treated to remove residual stresses from the coiling process.
•Headers are secured to outer casing, minimising loadings on process pipework.
•Return bends are not required, reducing maldistribution and fouling.
