High-pressure resistant solar collectors. Vacuum tube solar collectors are determined by the amount of sunlight, making them ideal for cold regions.
Heat pipe solar collectors do not circulate water inside the vacuum tubes, eliminating the worry of freezing and allowing for efficient heat collection even with low sunlight. In the unlikely event that a vacuum tube needs to be replaced, it can be done without stopping the system. They offer high reliability and durability. 【Features】 ○ High efficiency ○ No worry of freezing ○ Small heat container for quick startup ○ Low heat loss ○ Long-term maintenance of vacuum level For more details, please contact us or download the catalog.
