compact unpressured solar water heater

الوصف

1. The tube with special effect has the patent of interferential film technology, thus increasing the heat collection performance by *2% compared to normal pipes and bearing more stable performance. 2. The supporter is designed with an overall industrial model, which is simple,direct and stable. 3. The equipment has polyure thane heat insulating layer and the fully automatic constant-temperature and high-pressure quantitative foam. The heat insulating performance is endurable and steady. 4. The heat collecting efficiency is good, so the water temperature rises quickly.
