ETC Model
Evacuated Tube Collectors(ETC) Solar Water Heating system is made of 3 layered Borosilicate tubes which heats water efficiently even in low temparature. The Outer wall of inner tube is coated with selective absorbing material(CU, AL, SS wafers). This helps to increase absorption of solar radiation and transfers the heat into water which flows through the inner tube. It is new technology very cost effective and fast heating.
