Corona Features & Benefits

Absorber Plate

Utilizing a state-of-the-art ultrasound weld, copper fins and risers provide superior thermal connectivity between the fins and risers. Revolutionary coating is black chrome on nickel, producing a premium selective surface with maximum efficiency for solar energy use. Absorbability = 0.95

Tubing Grid

3/8" copper risers are brazed to 1" copper mainfolds for optimal flow distribution.

Piping Grid

Four 1 " Type M copper tubes.

Aluminum Foil

Attached to the insulation, acts as a barrier against out-gasing.

Solar Glass Glazing

A single pane of 1/8” thick solar glass is patterned to reduce reflection and tempered to maximize strength and durability. *Iron oxide content: 0.03%

Back Plate

Made of fiberglass for maximum benefit.

Insulation

1-3/16” polyurethane foam cast under and around the side of the absorber plate, retains the heat of the water in the collector. DFC-free P.U. meets U.S. and European standards.

Casing

All aluminum extrusion casings create a sleek framewall. Unique extruded profile allows easy anchoring to the roof (shingle, tile, tar) or collector stands.

Gaskets

All-around EPDM gasket. Highly resistant to temperature differences and UV radiation. Absorbs the differential expansion of frame and glazing.
