58*1800mm Tri-target vacuum tube for solar water heater solar collector tube
Advantage:
1>5 years warranty, long life span
2>Most competitive price and high quality
3>Quality assurance comply with ISO 9001-2008
4>Product quality in compliancee with CE
5>Fast delivery and rich export experience
6>OEM and ODM service
Technical Parameters:
Feature:
Tri-element tubes consist of two glass tubes which are fused together at one end. The inner tube is coated with a selective coating with 12 layers of spattering deposition technology that absorbs solar energy well. The coating is ALN/AIN-SS/CU by gradual change techniques, which has better heating efficiency.
The air is withdrawn ("evacuated") from the space between the two glass tubes to form a vacuum, which eliminates conductive and convective heat loss. Therefore, evacuated tubes could achieve up to 380 degree from theoretical condition, and act as the key component of solar water heater
Packaging:standard export cartons
Shipping:
1. Loading port:Shanghai, Ningbo
2. Sea transport for bulk order, Air transport and Courier Service for sample order
3. EXW,FOB,CIF all accepted
