THE STARMAX V SERIES SOLAR COLLECTOR for pumped glycol and drainback systems is shaped similarly to a standard four outlet collector, but includes a fifth outlet located at the bottom center. The internal upper and lower headers are sloped. When used in a drainback installation, this combination allows all fluid to drain without the need to pitch the collectors, saving labor for the installer, and allowing an array to be mounted plumb and level on the roof. The all-copper absorbers are selective blue coated for optimum heat absorption.
