ProgressivTube Passive Solar Water Heaters


	TAKE A LOOK INSIDE


	GLAZING GASKETS: A continuous gasket made of special long life EDPM synthetic rubber is compressed by the glazing caps to seal out the weather. The inner glazing spline is made of high-temperature tolerant EPDM.


	GLAZING: Outer glazing is tempered low-iron solar glass with 91% transmittance. Inner glazing is Teflon film, known for its high temperature tolerance (525F) and its long term durability and stability, transmittance 96%. The 3/4" air space between glazings reduces heat loss.


	FLUID CONNECTION: Inlet and outlet connections are made of nominal 3/4" diameter Type ``L" hard copper pipes. This allows for fast, leak-free sweat fitting plumbing connections.

CASE: The baked-on bronze acrylic finish of the hard temper, T6, extruded aluminum framewall and glazing caps, alloy 6061, assures years of attractive rust-free appearance. All rivets and bolts are aluminum or stainless steel. Aluminum back sheet 0.025"..


	INSULATION: Ridig closed cell polyisocyanurate foam board, the most efficient available, is used to maximize heat retention. Sides and ends of the unit have 1.5" board, R-value 10; bottom has 2" board, R-value 14;between tank tubes has 1.5" board, R-value 10.


	SPECIFICATIONS


	ABSORBER / STORAGE TANK: Constructed entirely of copper, the 4" diameter tubes are welded to the interconnecting pipes to form a series flow pattern. The tank is pressure rated to 300 psi and is coated with a high-temperature ``selective" solar radiation absorption surface that maximizes heat gain and reduces heat loss.
