Watlow®, the design and manufacture of complete thermal systems, introduces its new HELIMAX ultra-efficient electric heat exchanger with Continuous Helical Flow Technology, which helps reduce the coking and fouling typically associated with standard heat exchangers. Diminishing the coking and fouling rates can minimize heat exchanger maintenance intervals ultimately reducing downtime.
Some heat exchanger design methods, such as segmental baffles, have known dead zones where hot spots can occur. These fluctuations within the heat exchanger to either the sheath or tube skin temperature or the localized flow rate are common causes of coking and fouling, which can lead to system failures and expensive downtime.
HELIMAX with Continuous Helical Flow Technology enables an ultra-high heat transfer rate that lowers the skin and shell temperature rise above the process fluid and offers the ability to push the limit on high outlet temperature applications. It also minimizes fluid bypass assuring tighter sheath temperature control and provides smaller shell diameters. As a result, high pressures can often be handled with thinner shell walls or without resorting to expensive exotic materials.
HELIMAX is smaller and lighter weight compared to traditional heat exchangers offering significant benefits to space constraint applications such as offshore platforms or floating production storage and offloading vessels.
