In case of large commercial & industrial projects, where hot water requirement is in substantial quantity, Evacuated Tube Manifolds are used. Set Of 50 Tubes (25 on each side) are connected with a common header manifold in the centre. Cold water enters the manifold & tubes from bottom, gains heat energy from the Sun & flows upward.
Based on the system design, numbers of manifold collectors are connected in a combination of series & parallel connection. Flow & circulation of water is regulated through suitably designed pumping system as per the process requirement.
It is a Solar Collector where Copper Fins are connected with Riser Tube (Copper) by ultrasonic welding. Tube & fins are coated with special Solar Selective Coating to increase the heat absorption from solar energy. Series of riser tubes are connected with bottom cold water header & top hot water header. Water gains heat from solar energy & flows upwards.
