RREAL SPF Configurations Different RREAL installations showing possible SPF configurations
(2) SPF 32s • Hung vertically and in parallel
SPF Header • Headers are 22 inches on either end of the collector • Internal duct • Flexibility of penetrations for supply and return • Ability to join multiple collectors
(2) SPF 32s • Hung in landscape and in series
Parallel vs. Series Configuration Parallel Configuration Series Configuration Configuration in which the air can traverse panels through the headers before traveling through the body of a collector. This configuration is best when possible. Less fan power consumption, higher collector efficiency. Configuration in which the air must flow through each collector individually before traversing through any headers – No short cuts. (end to end) U-Shape
