SolaRay 2 is a forced-circulation, indirect system, designed primarily for climates that experience annual and persistent hard-freeze conditions. The specified heat transfer fluid is an industrial grade propylene glycol.
The Solaray 2 System solar storage tank incorporates an integral single-wall heat exchanger for maximum heat transfer effectiveness. The versatile SolaRay 2 solar storage tank meets or exceeds most major U.S. building and plumbing code requirements. The SolaRay 2 system is available with either AC or PV pumping options.
If properly installed and maintained the Solaray 2 forced-circulation glycol system can safely be deployed in areas that experience annual persistent hard freeze conditions. ICC-SRCC Rated Freeze Tolerance: – 60° F.
