SUGGESTED SPECIFICATION
The solar thermal collectors shall be model number _____________________ as manufactured by Chromagen™ Solar Water Solutions. The solar thermal
collectors shall be glazed, flat plate type, parallel tube design. The collectors shall be tested by the Solar Rating and Certification Corporation (SRCC)
and be SRCC certified OG-100. The collectors shall be tested in accordance with SRCC Standard 100 and their thermal performance rated according
to SRCC Document RM1.
The dimensions of the collector shall be ________ inches in length, ________ inches in width and 3.77 inches (95.8mm) in depth. The collector casing
shall be an anodized aluminum extrusion (alloy 6063 T5), minimum thickness of 0.05 inches (1.2mm). The collector casing shall be of an interlocking
construction design. There shall be no screws or fasteners penetrating the collector casing used to join casing sections together. The collector casings
shall have integral mounting channels along the entire length of all four sides that accept mounting clips with the same channeling configuration
for ease of installation and removal without penetration of the collector casing. Two solid and two vented plugs shall be installed in the sides of the
collector casing that can be easily moved from one opening to another to facilitate portrait or landscape installation while preventing moisture
infiltration and allowing moisture exfiltration in either orientation. The collector casing shall be fitted with four protective nylon moldings, one on
each corner, to prevent damage to the collectors or adjacent property during transport and installation.
The collector glazing shall be low-iron patterned and tempered glass with a minimum thickness of 1/8 inch (3.2mm) and a minimum solar
transmittance of 91%. The glazing shall be thermally isolated from the casing by a continuous EPDM gasket with MS polymer sealant applied to
minimize moisture infiltration. There shall be no screws or fasteners penetrating the collector casing used to hold the glazing in place.
The collector insulation shall consist of one layer of injected rigid polyurethane foam with a minimum thickness of 0.9 inches (23mm). There shall be
a second layer of glass wool insulation with a minimum thickness of 0.8 inch (20mm). There shall be an integrated aluminum foil barrier between
the glass wool and foam insulation layers to retain heat and prevent out-gassing. The collector backsheet shall be black Polypropylene material. The
cumulative total thermal resistance of the collector insulation shall be a minimum of R-8.
The absorber plate shall be 1050 aluminum sheet with a minimum thickness of 0.016 inches (0.4mm). The absorber plate shall be coated with a
spectrally selective black coating that achieves a minimum solar absorption of 90% and a maximum IR emission of 40%. The risers shall be a minimum
of 5/8 inch (15.9mm) O.D. Type M copper. The manifolds shall be a minimum of 1-1/8 inch (28.6mm) O.D. Type M copper. The risers shall be brazed
to the manifolds using a copper phosphorus braze alloy conforming to American Welding Society (AWS) classification L-CuP6. The internal riser and
manifold tube construction shall be designed to withstand a maximum working pressure of 145 psig. The risers shall be laser welded to the absorber
plate to maximize heat transfer and permanence of the bond. EPDM grommets shall isolate the manifold tubes from the collector’s aluminum casing.
