Split Pressurized Solar  Evacuated Tubes Water Heaters

Descriptions:

 Split pressurized solar water heaters consist of many solar Evacuated tubes collectors with high efficiency. And the solar collectors are easy installed and strenthen resistance of frost cracking and hailstone. The solar collector is consisted of super conducting vacuum heat collecting tube and header, so it's of great efficiency of heat collecting. The absorbing percentage of the glass vacuum collector is more than 96%. In the sunny days of spring or autumn, each collecting tube could make the water up to 90 degrees centigradeonly in 2.5 hours. The water tank uses enamel as internal bladder and polyurethane integral foaming as heat preservation material to improve the heat preservation ability. And it makes the system be used as usual under minus 50 degrees centigrade. The high corrosion-resistant and good heat preservation PPR pipe is used as the system's pipe, so it adds the good efficiency and long service of the system.

Working principles:

The water tank is separated from collector. Split pressurized vacuum tube solar water heater is convenient to install and use. It works with pressure up to 0.6 MPa and can normally work in all climates. The absorptive coating of vacuum tube is ALN/ALN-SS/CU. This coating has high absorbing ratio (0.94) and low emission ratio (0.6). The heat efficiency is 0.64. The life span of vacuum tube is 15 years. The vacuum tube is made of borosilicate 3.3. No water in the vacuum tube. Even if some vacuum tubes are broken, the split pressurized vacuum tube solar water heater can normally work.
