Specifications for “AVIN” SOLAR FLAT PLATE COLLECTOR:
A. COLLECTOR BOX – FRP (Fiber Glass Reinforced Body).

Details of Material Thickness and specifications: The housing is a single piece jointless unit moulded  from FRP having 2-3mm thickness.   FRP body collector housing is all weatherproof, light weight, very strong, extremely durable, self insulating, bad conductor of heat and so increases the efficiency of collector up to 20% by not allowing the energy gained to escape out. It is colorful, streamlined and elegant in appearance and it does not require periodic painting or maintenance.

Tested by CIPET(Central Institute of Plastics Engineering & Technology), FRP body of our collector shows a  tensile strength  in excess of 800,  plus extremely good resistance to acids and alkalies, making it the ideal “body”.  For good measure we also had a ten year old FRP body of our collector tested  at CIPETand  the tests showed no deterioration in its physical properties proving beyond any doubt that FRP(fibre reinforced plastic) is yet the best material for the outer shell of the collector.
