Raypak offers a new commercial boiler package with an application and sizing guide. Together they offer a low-cost, off-the-shelf solution to a problem that has been nagging system designers for years - how to avoid short-cycling and other system operational problems that may occur as more closed systems are designed with one or several very low-water volume loops.

The eight-page Sizing Guide/Brochure describes pertinent applications, offers well-researched and time-proven sizing guidelines, and specificies the tanks that will be required for the vast majority of commercial systems. While the standard tanks detailed are relatively small, they're all that is usually needed. They are constructed with extra connections for the needed system decoupling. Additional information can be found on the website, including white papers in the Tech Corner. www.raypak.com.
