FI4Cf 0 SOLAR HEAT EXCHANGER DESCRIPTION: The Revolution TM Solar Collector is manufactured in Chico, California. The collector is a specially developed, highly stabilized polyolefin and is of parallel, circular channel design. The collector channels are dimpled using a subtle combination of angle, depth and frequency. This technology directs the water into a spiral, revolving flow exposing all the water molecules to the suns warmth. It is unglazed, uninsulated, and designed for low temperature applications such as swimming pool heating, heat pumps, aquiculture, and hydroponics. DIMENSIONS: Header Length = 50.875 in. (1.29 m) Width (Panel body) = 47.5 in. (1.21 m) Overall Dimensions Effective Area 4 ft. X 8 ft. (1.22 X 2.44 m) 30.8 ft (2.86 m 4 ft. X 10 ft. (1.22 X 3.05 m) 38.8 ft (3.60 m 4 ft. X 12 ft.

WEATHERABILITY: Weatherometer, accelerated outdoor exposure, and other extensive laboratory testing demonstrates long -term weatherability of Revolution TM collectors (see warranty). Additionally, FAFCO's experience of 30+ years and over 1,000,000 collectors installed confirms that the proprietary stabilization and high mechanical strength results in negligible warranty over the FIFTEEN -YEAR warranty period.
