Collector JuraSol is a modern construction based upon copper absorber covered with high selective layer TINOX. Applied layer helps to utilize solar energy reaching the collector surface in very effective manner.
Main advantages of JuraSol collector are: 
- large collector surface – 2,85 m2 enables high energy gains, causing reduction of domestic hot water preparation costs,
- absorber – made in technology of ultrasonic welding of absorber pipes with absorption metal sheet. This method guarantees best connection of metal sheet with pipe on entire length. Additional advantage of ultrasonic welding is the fact that the connector – soft solder – is not present in such type of connection. Taking into account the fact that thermal conductivity of copper, of which the harp and plate is made, is 401 W/m2K, and thermal conductivity of solder is only 60 W /m2K, this is a considerable advantage in heat transfer,
- frame – made in modern aluminum bending technology from one profile section, without unnecessary welds in corners. A frame without welds is much more tight, looks better and there is no risk of unsealing after several years of operation,
- powder coating – collector main frame is painted in powder coating technology,
- insulation made of mineral wool – insulation of collective set with thickness of 40 mm and the side insulation with thickness of 20 mm,
- lack of edge on lower collector housing, enabling free snow slippage,
- hardened, hail-resistant solar glass, thickness - 4 mm.
Assembly:
• special desiged assembly sets enabling quick and safe collector assembly on each roof type and as free-standing structure on the ground
• fixing systems made of stainless steel and aluminum.
