Raypak’s product and associated application sizing guide offers an off-the-shelf solution to system designers on 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. This includes hydronic systems with multiple zones or hot water systems needing to utilize a heat exchanger/tank approach. The eight-page guide describes pertinent applications, offers well-researched and time-proven sizing guidelines and specifies tanks required for the vast majority of commercial systems.
