Specification

The material used for the outer manifold is either 0.4mm Color steel or SUS304-2B stainless steel. A similar sentence can be generated by stating that the outer manifold can either be made of 0.4mm Color steel or SUS304-2B stainless steel.
2. Insulation material: PU
3. Inner tank material: 0.5mm Stainless steel
4. When it comes to the frame material for our product, we offer two options: galvanized steel and SUS304-2B stainless steel. Both materials are highly durable and provide excellent protection for the product's structure. Galvanized steel is known for its corrosion resistance and affordability, making it a popular choice for many customers. On the other hand, SUS304-2B stainless steel is a premium option that offers superior strength and a sleek, polished appearance. Whether you prefer the cost-effectiveness of galvanized steel or the high-end appeal of stainless steel, we have the right frame material to meet your needs.
The vacuum tube material used in this context is borosilicate glass 3.3, which ensures durability and reliability. Additionally, the vacuum tube is enhanced with an AL-SS-CU absorb coating, which further enhances its performance and efficiency.
6. Collector mounting: flat roof or inclined roof

Working Principle

The vacuum tubes used in solar heating are directly connected to a manifold tank. The evacuated tubes are designed to heat cold water using solar radiation. As the hot water has a lower specific gravity than cold water, it rises up to the manifold tank while cold water sinks down to the vacuum tubes. This constant flow enables the cold water in the tank to gradually heat up. In an active open-loop solar system, the hot water from the manifold tank is pumped into a separate storage tank, while the colder water is recirculated back to the manifold for further solar heating.
