Import Closed Loop Flat Plate Split Solar Water System — Buy in wholesale FOB from Supplier in China

The Millionsun Group closed loop flat plate split solar water system integrates flat plate collectors, insulated water tanks and an automated control unit into a forced circulation heating setup. Designed for both residential and large-scale applications such as hospitals, hotels and schools, the system operates with automatic temperature control for safe and convenient hot water delivery. The flat plate collectors are engineered for efficient heat absorption, while the split design allows flexible installation of tanks and collectors at optimal positions for sunlight exposure.

Flat plate collectors in this system are typically constructed from copper or aluminium absorbers with selective coatings to maximise thermal efficiency, paired with tempered glass covers for durability. Standard industry configurations often include a 20-year lifespan for collectors and 10 years for tanks, with typical operating temperatures ranging from -10°C to 90°C. The system’s closed loop circulation prevents freezing in colder climates, and the control unit maintains water temperature within a set range to avoid overheating or scaling.

This setup is used by commercial facilities and households in regions with moderate to high solar irradiance, where reliable hot water supply is critical. Buyers typically confirm the collector area to match demand, with common sizes spanning 2 m² to 10 m² per module. Trade terms often include FOB or CIF from Chinese ports like Shenzhen or Guangzhou, with packaging tailored for sea freight to protect the collectors and tanks during transit.

Millionsun Group is based in Dongguan City, Guangdong Province, China, operating from a 50,000 m² facility that houses production lines for solar flat collectors, water tanks and brackets, alongside an R&D and test centre. The company was established in 2006 and employs approximately 1,600 workers, with a focus on OEM and ODM partnerships for solar water heating systems. Its manufacturing processes are ISO9001 certified, and its products carry multiple international certifications, including CE and SOLAR KEYMARK.

The supplier’s profile indicates a strong emphasis on brand development, with many clients signing agency agreements to distribute Millionsun-branded products in local markets. While the response rate and average response hours are currently listed as zero, the company’s long-standing presence in the industry and its comprehensive production capabilities suggest a well-established operation. Buyers are advised to confirm current response times and verification status directly with the supplier.
