Product Detail
Solar Keymar Heat Pipe Solar Collectors 1. EN12975 2. Solar Keymark 3. Efficiency: 74.4% 4. Warranty: 5year

Model: JHC-5818-24-E

The Jinyi Pitched Roof Heat Pipe Solar Collectors composed of a series of borosilicate glass pipes with double air gap, welded at the end, inside which a vacuum is caused. The internal air gap is made selective due to the absorption of solar electromagnetic radiation through a multi-layer metalisation called “CERMET”, created using completely recyclable products.

The absorption unit is made up of a copper pipe (called heat pipe, inside with liquid for heat exchanging), positioned in contact with specific aluminum heat absorbers, which increases the heat exchange surface.

Each unit is contained in a glass pipe, and is then connected in parallel to a collector situated on the head of the panel, which collects the carrier fluid which flows through every circuit.

A metal frame with electro-coloured aluminium edging of a suitable thickness, as envisaged by regulations for saline mist corrosion resistance.

The assembly of the individual components which make up the structure takes place using special brackets for simplified interlocking assembly.

The protective structure (manifold) of the copper distribution collector is made of electro-coloured aluminium, fully insulated with special rock wool insulation.

ADVANTAGES

Great performance in minimal spaceSolution can be adapted to any type of roofSimplified pipe removal thanks to the new EASY CHANGE systemReduced heat losses thanks to the vacuum technology
