CHROMAGEN has fine-tuned the design and manufacture of solar collectors to an art.
Collectors are assembled using quality materials and advanced techniques, which result in highly efficient, durable products you can depend on for years to come. The products are environmentally friendly, remarkably versatile and offer high performance even in extreme environments.
The wide range of solar collectors enables CHROMAGEN to provide cost-effective solutions which comply with a variety of international standards
1. Absorber Plate Consists of copper fins ultrasonically welded to copper risers, to provide excellent heat transfer between the fins and risers, ensuring high efficiency.
Inexpensive yet durable aluminum absorber plate is available.
2. Absorber Plate Coating
Coated either with a sputtering coating, or with black chrome on nickel, or with highly distinctive black solar paint. All allow excellent energy absorption even in cooler climates.
3. Insulation
The absorber plate is encased in 25 mm rigid polyurethane foam, with an option to additional layer of glass wool , retaining the collector's heat.
4. Solar Glass Glazing
The single pane 3.2 mm solar glass is patterned to reduce reflection and tempered to maximize strength and durability. The 0.03% low iron oxide content enables a high solar transmittance of 91%.
5. Casings
A. Aluminum
All anodized aluminum extrusion casings are made of solid construction available in a natural or black, or red color.
B. Galvanized Steel
Galvanized steel casings are available in black, grey or white polyester finishing.
finishes.
6. Tubing Grid
5/8’’ or 8 mm copper risers brazed to 1 1/8” or 7/8’’ copper manifolds with optimal flow
distribution.
7. Piping Connection
Four 3/4" BSP female brass adaptors , flare for quick fittings or clear cut edge for connector brazing.
8. Back Plate
The back plate is made of black polypropylene sheet.
9. Aluminum Foil
The aluminum foil acts as a barrier against out-gassing, integrated to the insulation.
