- Aluminum foil- 100 microns Aluminum foil to protect polyurethane casting.
- Insulation - CFC Halogen free polyurethane or high density rock wool boards.
- EL-AT series: unique mixture of glass wool insulation bonded together with CFC Free high density polyhorytane casting
- Back plate - P.V.C /Polypropylene or Aluminum sheet.
All collectors undergo test pressure of 12 bars whereas permitted working pressure is 8 bars
Our flat plate collector`s copper piping is welded using laser technic. to an Aluminum absorber coated with Titanium Oxide coating with solar absorptance of 95%-97% and emittance of 5% - 7% which ensures high efficiency of the solar collector and effective heat conductivity.
The collector`s case is made of extruded aluminum coated in powder paint or anodized .the frame has a very easy and safe fixing fixture using nuts of M8 rivets.
Our unique insulation consist of a mixture of an high density CFC Polyhorytane casting together with glass wool, this insulation ensures the low thermal losses of the collector. The insulation is protected by a 100 microns aluminum foil.
Collector`s casing back plate is made of aluminum or PVC
The collector`s glass is a solar low iron tempered glass with solar transmittance or more than 91% .
Our collectors were tested and approved by certified laboratories such as CENER and ITW in Europe which have tested the collectors according to the EN 12975 part 1+2 standards and by the SABS laboratory in South Africa according to the South African standards ,
Our collectors are certified in Europe by Cener and ITW and by ESKOM in South Africa for the rebate program.
