2013 DIN EN12975 Solar Collectors Project with CE Certificate

EN12975 Solar Collectors Project with CE Certificate:

Sanneng Solar collector with SRCC & Solar Keymark Certificate

• The pipeline and heat exchange use TU1 copper. Thermal anti-freeze media is used in the inner tube to Vacuum Tube. No water flows into Vacuum Tubes. The manifold made of Aluminum Alloy to strength its structure. There is ventilation tunnel to maintain the system pressure level.
• The system can withstand the pressure as high as 0.6MPa at operation.
• The modular design of the system provides a flexible configuration to meet variety needs from customers.
