ETC Manifold Collector

ETC tubes are made of two concentric glass tubes fused at the bottom end with vacuum in between. The outer surface of inner tube is coated with selective three target coating with CU-SS-Aln for higher absorption of heat.  Each tube has a surface area of absorption of 0.1M2.  Manifold collectors consist of multiple ETC tubes ranging from 10 to 60 depending on te design requirement. The ETC tubes could be on either side of manifold tank or on single side of manifold tank. The water circulation from manifold tank and tube occurs on principal of ‘Thermosyphon’.
