Main Specification

Vacuum tubes can be made from stainless steel or color steel, and they operate under non-pressure conditions.
The food grade stainless steel used for the inner tank is SUS304 2B, with a thickness ranging from 0.31mm to 0.45mm.
The material used for the outer tank is either 0.4mm thick food-grade SUS304 2B or BA stainless steel, or 0.5mm thick galvanized steel. This ensures the tank is durable and resistant to corrosion, making it perfect for use in various industries. The stainless steel material is particularly suitable for industries that require strict hygiene standards, such as the food and beverage industry. The galvanized steel variant, on the other hand, offers good mechanical strength and excellent corrosion resistance, making it suitable for use in more rugged environments. Overall, the choice of material for the outer tank depends on the specific needs and requirements of the industry or application in question.
When it comes to choosing the material for the frame of your product, you have several options to consider. One option is to use 1.2mm stainless steel. Alternatively, you may choose to use 1.5mm galvanized steel. If you are located in an area with a corrosion problem, you may want to consider using anodized aluminum instead. Regardless of which material you choose, you can rest assured that your product will be built to last.
Tube: A high-quality glass tube is used, which is coated with AL-N-AL or AL-N-AL-CU-SS three target coating. Let's discuss a different approach to generating content based on the original text.

Safety and long life

By switching to a compact non-pressure solar water heater, you can conserve up to 360 KW of energy annually when compared to an electrical water heater. The added benefit is that solar water heaters have a long lifespan. In fact, you can expect yours to last for 15 years before it needs replacing. So not only will you be doing your bit for the environment, but you will also be saving money in the long run by investing in a solar water heater.

By incorporating side exhaust into the design, the water tank's service life is significantly improved. This feature helps to increase the durability and longevity of the tank, ensuring that it operates efficiently over a long period of time. Side exhaust technology helps to remove excess heat and reduce pressure in the tank, which helps to prevent damage. With this innovative design feature, the water tank can provide reliable and consistent performance for many years to come.

Packing Details

We have one carton containing a solar water tank and another carton holding a stand frame. Additionally, there are ten solar vacuum tubes included per carton.
We accept sample orders with a minimum order quantity of less than 2 pieces. These samples will be carefully packed in wooden boxes for protection during transport.

Working principle of solar water heater

The Thermosyphon low pressure solar geyser is an efficient solar water heater that employs a straightforward thermal circulation process. This system operates through the heating of cold water carried by solar vacuum tubes, which then causes the hot water to rise to the tank. In turn, the cold water in the tank flows back into the solar vacuum tubes, creating a natural thermosyphon circulation process. As a result, the water in the tank gradually becomes hot, providing an ample supply of hot water. This process is simple and highly effective, allowing you to save on energy costs while enjoying the benefits of hot water production.
