All-Copper Solar Collectors

COPPER FINS ULTRASONICALLY WELDED TO COPPER RISERS

CHROMAGEN has fine-tuned the design and manufacture of solar collectors to an art. 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.

Our products are environmentally friendly, remarkably versatile and offer high performance even in extreme environments. CHROMAGEN panels are suitable for all kinds of hot water systems and provide consistent results under any weather conditions.

Selective coated collector combining all known effective features:

• Best selectivity - high absorption and low emissivity
• No galvanic corrosion
• Ultrasonic welding of copper strips to risers - high fin efficiency
• Aluminum case - rigid and aesthetic with roof integration slots

• 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.
  



• 2. Absorber Plate Coating

  Coated either with a sputtering coating, or with black chrome on nickel, or with highly distinctive black solar paint. All enable excellent energy absorption even in cooler climates.
  

• 3. Insulation

  The absorber plate is encased in rigid Polyurethane foam, with an optional layer of glass wool to provide high thermal resistance.



• 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 low iron oxide content of 0.03% 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 color.
  
  B. Galvanized Steel - inexpensive yet durable, galvanized steel casings are available in black, gray or white polyester finish.

• 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 BSP female brass connections.



• 8. Back Plate

  The back plate is made of a black polypropylene sheet.
  



• 9. Aluminum Foil

  The aluminum foil is attached to the polyurethane foam and acts as a barrier during the polyurethane polymerization.
