Working Principle
Water flows through the vacuum tubes, where it is heated directly by collected solar energy. This heated water continuously circulates through the storage tank using the thermosyphon principle, efficiently heating the tank contents. The Suntech direct solar heaters are suitable for lightly pressurized systems and can effectively handle mineralized water inputs.
Operating Conditions
- Water Quality: Ensure clarity and pre-treat water with TDS > 600 mg/l and hardness > 200 mg/l CaCO3 for optimal performance.
- Maximum Operating Temperature: 300°C
- Maximum Operating Pressure: 6 bar
