SPECIFICATION SHEET HELIMAX™ Ultra-Efficient Electric Heat Exchanger Diminish Heat Exchanger Maintenance Intervals Due to High Fouling Rates with Continuous Helical Flow Technology™ The HELIMAX™ is a next generation heat exchanger with Continuous Helical Flow Technology™ that enables ultra-high heat transfer unlike large, traditional heat exchangers with dead zones. Fluctuations within the heat exchanger to either the sheath temperature or the localized flow rate are common causes of coking, which can lead to system failures and expensive downtime. Some heat exchanger design methods, like segmental baffles, have known dead zones where hot spots can occur, accelerating the coking process. The HELIMAX provides better performance and longer heater life in a smaller footprint allowing you to reduce maintenance intervals leading to increased productivity. Performance Capabilities • Unit wattages: Up to 5 MW • • • • • • • * System wattages: Up to 200 MW* Voltages: 690V Design temperatures: Up to 1742°F (950°C) Design pressure: Up to 3000psi (206 bar) Maximum ambient temperature: 176°F (80°C) Maximum ambient temperature: -76°F (-60°C) Media phase: Single-phase liquids and gases Multiple system configurations can include multiple units in parallel, in series or a combination of these Watlow® and WATCONNECT® are registered trademarks of Watlow Electric Manufacturing Company HELIMAX™ and Continuous Helical Flow Technology™ are trademarks of Watlow Electric Manufacturing Company. Features and Benefits Continuous Helical Flow Technology™ • Industry-leading heat transfer (two to five times factor improvement compared to legacy technologies) • Enables lower skin and shell temperature rise above the process fluid compared to segmental baffles • Offers the ability to push the limit on high outlet temperature applications (above 600°C operating temperatures) • Minimizes fluid bypass • Assures tighter sheath temperature control • Provides smaller shell diameter • Leads to higher pressures without going to exotic vessel designs • Offers ability for retrofit with field measurements of existing shell Reduces coking and fouling • Eliminates dead zones assuring tighter sheath and shell temperature control • Creates lower skin temperatures • Improves the velocity profile on the elements Overall weight and size reduction • Able to greatly reduce the overall size of the heat exchanger or quantity of system units required • Enables significant benefit to space constraint applications in offshore platforms and floating production storage and offloading vesse
