SOLAR THERMAL COLLECTORS
Collectors are assembled using the highest quality materials and advanced techniques, which
result in highly efficient, durable products you can depend on for years to come.
Optimal heat absorption and efficiency.
Riser tubes are laser welded to the absorber
plate which ensures optimum heat transfer
and permanent bond.
Three insulation layers provide a cumulative
thermal resistance value of R-8.

1. Low-iron patterned and tempered glazing
provides superior strength, anti-glare
surface and 91% solar transmittance.
2. Aluminum absorber plate with spectrally
selective black coating provides more
than 90% solar absorption and less than 40%
IR emission for high performance even in
cooler climates.
3. Rugged nylon glass fiber moldings on all four
corners protect collectors and adjacent
property from damage during transport and
installation.
4. 1-1/8 inch outside diameter (O.D.) copper
sweat inlet/outlet connections.
5. Glass wool insulation layer

6. Black anodized extruded aluminum casing -
interlocking construction assembly - requires no
fasteners that loosen over time and allow
moisture infiltration.
7. Integrated aluminum foil insulation barrier.
8. Injected rigid Polyurethane foam insulation layer.
9. Durable black Polypropylene backsheet - resists
punctures during transport and installation,
resists corrosion for the life of the collectors.
10. Type M copper risers 5/8" and manifolds 1-1/8" are
brazed together in a parallel tube configuration
ensuring optimal flow and a low pressure drop.
Collectors may be installed in portrait or
landscape orientation.
