An electric heat exchanger with Continuous Helical Flow Technology helps reduce the coking and fouling typically associated with standard heat exchangers, says its manufacturer. Diminishing the coking and fouling rates can minimize heat exchanger maintenance intervals, ultimately reducing downtime.

Helimax enables high heat transfer rates that lower the skin- and shell-temperature rise above the process fluid. It also minimizes fluid bypass, helping to ensure tighter sheath temperature control. With smaller shell diameters than comparable exchangers, says the company, high pressures can be handled with thinner shell walls or without requiring exotic materials.
