Evacuated Tube Collector is made of Three layer borosilicate glass tubes evacuated for providing insulation. The outer wall of the inner tube is coated with selective absorbing material. This helps absorption of solar radiation and transfers the heat to the water which flows through the inner tube.

  • Suitable for domestic(Home)applications available in different capacities.
  • Both Sided Welded Galvanized/Stainless Steel inner Tank with enamel Coating.
  • Superior Quality PUF Insulation.
  • Pure Polyester Powder Coated Galvanized Outer Cladding.
  • MNRE Approved Collector Design.
  • Three Target Selectively Coated Borosilicate.
  • Pure Polyester Powder Coated Stands & Support with White, Orange & Green Combination.
  • Indirect heating- Heat Exchanger type and Pressurized application systems are also available.
