E-SERIES Efficient, Compact, Rapid-Start Steam Generator Systems (150-1, 200 BHP) E-Series See our SigmaFire page for boilers between 25 and 200 BHP. Clayton’s E-Series line of boilers are compact and highly efficient. With a unique flowcounter-flow heat exchanger, these steam workhorses start up fast and react quickly to system load changes without compromising system pressure. Another advantage of Clayton’s E-Series is the way these generators control internal water flows to carefully manage TDS build-up, and how they dispose of the water in a concentrated manner that reduces wasted heat, water and chemicals. All of this is accomplished without the need for a large pressure vessel, for a safer environment in the boiler room. Just a few of the many advantages of Clayton’s E-Series line of boilers: Quick startup High-quality, consistent steam output Inherent high level of operator safety Low weight and space requirements Strong fuel-to-steam efficiencies Quick response to load swings, with no carryover Lower water waste and reduced blowdown Low NOx, skidding, packages systems and more available With the Clayton E-Series, low NOx systems are available to meet regulations down to 6 ppm. We also offer skidding, mounting, containerizing and other options enabling greater flexibility in your choices for steam generation.
