Import Blue Thermal Solar Flat Plate Collector — Buy in wholesale FOB from Supplier in China

The Blue Thermal Solar Flat Plate Collector from Millionsun Group is a direct-absorption solar thermal unit designed for residential and light commercial heating systems. It features a 1.2 mm thick aluminum frame with a black chrome selective coating on the absorber plate, a 4 mm low-iron tempered glass cover, and 50 mm polyurethane foam insulation. The collector has a net aperture area of 2.1 square meters and an optical efficiency of 71% at 30°C, as measured under standard test conditions per EN 12975-2.

The absorber coating is a blue-black selective surface, typical for high-performance flat plate collectors, offering low emittance and high solar absorbance. The internal flow channels are made of copper with a welded fin attachment, ensuring efficient heat transfer. The insulation density is 32 kg/m³, a standard value for solar thermal units in this class. The unit is rated for maximum operating pressure of 6 bar and can withstand freeze cycles down to -20°C without damage, consistent with European thermal collector norms.

This collector is commonly used in domestic hot water systems, swimming pool heating, and small-scale industrial pre-heating applications. Buyers include solar installers in Europe and the Middle East, property developers in warm-climate regions, and renewable energy contractors. The product is shipped in wooden crates with corner protectors, with a typical bulk packaging of 10 units per pallet. Trade terms are FOB Guangzhou, with lead time around 25 days after deposit confirmation. Minimum order quantity is not specified in the listing and should be confirmed directly with the supplier.
