HELIMAX™ Ultra-Efficient Electric Heat Exchanger

Brand: Watlow

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.
