58 1800mm Solar Silver Titanium Collector Tube

INTRODUCTIONS

1. The inner tube of this kind of solar vacuum tube use offset technology. The outer tube is with siver and titanium element. With these 2 technologies, all the sunlight can heat the cold water in the inner tube. No heat will be wasted. This kind of solar vacuum tube has 50% efficiency more than normal three layer coating vacuum tube.

2. The outer tube with siver and titanium element can reduce heat loss by radiation at night, so this kind vacuum tube lose less heat at night.

PRODUCT FEATURE

1. Temperature preservation is equipped with standard electric water heater

2. Scientifically designed bracket can hold the tank firmly

3. High quality vavuum tubes

4. Simple structure, easy plug-in installation. Cheap and efficient

5. Guaranty: 8 years

6. Colors according to customers’ needs
