Collectors shall be SunEarth Empire model ________, and shall be of the glazed liquid flat plate type. Collectors shall be tested in conformance with ASHRAE 93-2003 and Solar Rating and Cerification Corporation (SRCC)100-10, ISO 9806-1 & 9806-2 and have their thermal performance rated according to SRCC Document RM-1. The collec-tors shall be certified by SRCC and the Florida Solar Energy Center (FSEC), and list-ed by the International Association of Plumbing and Mechanical Officials (IAPMO).GENERALThe dimensions of the collector shall be _________ inches in length, _________ inches in width and 3.25 inches in depth. The collector casing shall be an anod-ized aluminum extrusion (alloy 6063 T6), minimum thickness 0.060 inch, with an architectural dark bronze finish. The casing shall have notched framewalls for ease of plate removal and reinstallation. Sheet metal screwed fasteners shall be stainless steel (18-8 #10). The backsheet shall be painted textured alu-minum not less than 0.014 inch thickness. A 1 inch vent plug shall be installed in each of the four corners of the backsheet to minimize condensation. An inte-gral mounting channel shall allow the solar collector to be mounted without penetration of the extruded aluminum casing.GLAZINGThe collector glazing shall be one sheet of low iron tempered glass, with a minimum of 0.125 inch thickness (0.15625 inch on EC/EP-40, EC/EP-40-0.75), and a minimum transmissivity of 91 percent (89 on EC/EP-40, EC/EP-40-0.75). The glazing shall be thermally isolated from the casing by a continuous EPDM gasket. There shall be a continuous secondary silicone seal between the glass and casing capstrip to minimize moisture from entering the casing.INSULATIONThe insulation shall be foil-faced polyisocyanurate foam sheathing board of a minimum 1 inch thickness, siliconed in place to the aluminum backsheet, cov-ered by low-binder fiberglass of a minimum 1 inch thickness, providing thermal isolation of the foam from the absorber plate. Total thermal resistance shall be a minimum of R-12. The sides and ends of the collector shall be insulated with a minimum of 1 inch foil-faced polyisocyanurate foam sheathing board.ABSORBER PLATE AND PIPINGThe absorber shall consist of a roll-formed copper plate of no less than 0.008 inch thickness. Risers shall be a minimum of 0.50 inch O.D. Type M copper tubing on no more than 4.56 inch centers continuously soldered to the plate utilizing a non-corrosive solder paste with a melting point of 460oF. The risers shall be brazed to 1.125” O. D. Type M copper manifolds (0.875” O.D. Type L on EC/EP-24-0.75, EC/EP-32-0.75 and EC/EP-40-0.75) utilizing a copper phospho-rous brazing alloy with no less than a minimum 5 percent silver content, and conforming to the American Welding Society’s BCuP-3 classification. EPDM grommets shall isolate the manifold from the aluminum casing. The absorber plate shall be designed for 160 psig maximum operating pressure.ABSORBER COATING AND PERFORMANCE CURVEA) Black Chrome (EC Series): The absorber coating shall be black chrome on nickel with a minimum absorptivity of 95 percent and a maximum emissivity of 12 per-cent. The instantaneous efficiency of the collector shall be a minimum Y-intercept of 0.735 and a slope of no less than -0.730 BTU/ft2.hr.oF.B) Moderately Selective Black Paint (EP Series): The absorber coating shall be a moderately-selective black paint with a minimum absorptivity of 94 percent and a maximum emissivity of 56 percent. The instantaneous efficiency of the collector shall have a minimum Y-intercept of 0.726 and a slope of no less than -0.910 BTU/ft2.hr.oF.Note Please refer to the SRCC website at www.solar-rating.org for the actual y-intercept and slope for each collector.Due to SunEarth’s policy of continuous product improvement, specifications are subject to change without notice.8425 Almeria Ave. • Fontana, CA 92335(909) 434-3100 • Fax (909) 434-3101MANUFACTURED BY: AVAILABLE FROM:ES 4/13MODEL EPTHERMAL PERFORMANCE RATINGS*MODEL ECA(-9oF)B(9oF)C(36 oF)D(90 oF)E(144 oF)1,2901,210 1,035 600 150 965 890 720 315 -645570410 70 -Category(Ti-Ta)A(-9oF)B(9oF)C(36 oF)D(90 oF)E(144 oF)1,3601,2501,070 700 3301020 910 745 400 95690580420120 -Ti = inlet ?uid temp; Ta = ambient air temp.
