Engineering-Grade Solar Hot Water System – Flat Plate Pressurized Model

Designed for performance-critical environments, this flat plate solar water heating solution combines efficiency, safety, and adaptability for large or small scale hot water needs.

System Specifications

Utilizes D-DOS high-absorption thermal coating (93% absorption ratio).

Modular unit composition enables efficient transport and phased installation.

Fully customizable tank capacity (150L–300L), material (enameled or SUS304 stainless steel), and installation brackets (0°, 25°, 45°).

Engineered with pressurized storage tanks to support booster pumps or direct municipal supply.

Long operational lifespan with negligible thermal degradation.

Gravity or pump-based circulation; no need for complex control systems.

Ideal Applications

Commercial buildings, construction sites, multi-family dwellings.

Excellent performance in extreme climates; suitable for winterized use.

Key Engineering Benefits

Pressure-bearing core supports multi-point simultaneous water usage.

Eliminates risk associated with vacuum tube explosion and hail damage.

Compact rectangular structure allows integration into facades or rooftops.

Technical Process
Solar radiation heats a fluid within the absorber core. The heated medium circulates through the closed loop to deliver thermal energy into a pressurized tank, offering high-temperature, consistent-pressure hot water delivery.
