Keith Modglin of Indianapolis, Indiana said that the Shadow keeps our waterline in the boiler right on target.
John Williams of Toronto, Ontario, Canada says that the Shadow equipment has stabilized water level in their customers steam generators.
Rich McGraw of Mainstay Mechanical sold his client a new Shadow for one of their boilers, and was so pleased they ordered the second Shadow.
Henry Vey of X-cel Company said his water level in their steam generator is much more stable than before the shadow was installed. This has stopped the nuisance shut downs due to water stabilizations.
