Solar Heat Collector
1. The high quality and intelligent product design ensures unbeatable value for money.
2. The robot-controlled production line ensures the highest levels of precision during the production process.
3. Automatic production data acquisition and thereby traceability of each products’ raw material, producing date, producing worker, and delivery time easily and quickly.
4. Three times quality check by 100% full-automatic pressure test in a closed cabin.
5. The resistance and longevity of the welding seam with around 10048 welding spots per absorber is proven through accelerated ageing tests.
Product Introduction:
Solar heat collectors are high-efficiency, eco-friendly devices that convert solar radiation into thermal energy. Widely used for domestic hot water, heating, and industrial preheating, these collectors feature a compact design, flexible installation, and long service life, making them a core component of modern solar thermal systems.

Note : ① Rated efficiency: The total irradiance on the daylighting surface of the collector is 1000W/㎡, and the temperature difference between
the average temperature of the collector and the ambient air temperature is 50°C. Calculate the efficiency value of the solar collector according to
the instantaneous efficiency equation of the collector's daylighting area.
② Rated power: The total irradiance of the collector lighting plane is 1000w/㎡, and the collector power when the temperature difference between
the average collector temperature and the ambient air temperature is 50 ° C is equal to the product of the rated efficiency and the day lighting area and 1000W/㎡.
