Main Specification

Stainless steel and color steel are commonly used materials for vacuum tube non-pressure systems. These materials offer durability and resistance to corrosion. The vacuum tubes are designed to withstand high temperatures and maintain efficient energy transfer. By rearranging the given content, we can emphasize the importance of stainless steel and color steel in creating reliable vacuum tube non-pressure systems.
The tank's inner layer is made of high-quality SUS304 2B food grade stainless steel, with a thickness ranging from 0.31mm to 0.45mm. This ensures that the tank is durable, safe, and suitable for storing any type of material. The stainless steel construction is also easy to clean and maintain, making it an ideal choice for various industries. Whether you're in the food and beverage sector or the manufacturing industry, this tank's inner layer will provide the perfect storage solution for your products.
The material used for the outer tank is either 0.4mm food grade stainless steel, specifically SUS304 with a 2B or BA finish, or 0.5mm galvanized steel. Both options provide a durable and sturdy foundation for the tank, ensuring long-lasting performance and reliability. Whether you choose stainless steel or galvanized steel, you can be confident in the quality of the outer tank and its ability to protect the inner components of the tank.
To address corrosion issues in coastal areas, we have the option of using a frame made of either anodized aluminum, 1.2mm stainless steel, or 1.5mm galvanized steel.
AL-N-AL-CU-SS Three target coating is applied to a high birosiligate glass tube for enhanced features. Another option is to have AL-N-AL coating on the tube.

Technical Specification

- The inner tank of the product is made of food-grade stainless steel, precisely measuring 0.41mm. The primary material used is SUS304-2B, and an alternative option is available with SUS316L.

The outer tank of this vessel is made from high-quality food-grade stainless steel (SUS304-2B), specifically 0.41mm thick to ensure durability and longevity. This material is perfect for protecting the internal components and ensuring they remain free from contamination or corrosion. The SUS304-2B steel is a great choice for applications where hygiene is of utmost importance, as it is non-reactive, non-toxic, and easy to clean. Overall, this tank is designed to provide reliable, long-lasting performance for a wide range of applications.

The bracket is made of galvanized steel that has a thickness of 1.5mm. Its angle can be adjusted to 20°, 30°, or 45° depending on the need.

4. Insulation: 55mm polyurethane layer.

The vacuum tube is made of borosilicate glass 3.3, while the absorb coating is crafted from a combination of aluminium, stainless steel, and copper. This configuration allows for optimal absorption of solar energy and efficient thermal transfer.

The material used for the seal is Stabilized High Temperature Silicon. It is a high-quality silicone that is specifically designed to withstand high temperatures. This silicone material is specially formulated to provide excellent stability and durability, making it ideal for sealing applications in environments with extreme heat conditions. With its superior heat resistance properties, the Stabilized High Temperature Silicon ensures that the seal remains intact and reliable even under extreme temperature variations. Whether it is for industrial or automotive applications, this reliable seal material guarantees optimum performance and longevity in high-temperature environments.

7. It resists 25mm hail.

8. Heat preservation: 72 hours

Packing Details

We have a complete solar hot water system that comes in 2 cartons - one carton for the tank and another carton for the stand frame. Additionally, we have the solar vacuum tubes available in cartons of 10 pieces.
We offer a sample order with a minimum order quantity of less than 2pcs. The products will be carefully packed in a sturdy wooden box.

Working principle of solar water heater

The solar water heater known as a thermosyphon low-pressure solar geyser functions through a straightforward thermal circulation process. It operates by utilizing solar vacuum tubes to heat cold water. As the water is heated, it rises and enters the storage tank. Simultaneously, the cold water in the tank flows back into the solar vacuum tubes, creating a natural circulation known as thermosyphon. Through this continuous flow, the entire volume of water in the tank gradually becomes hot.
