Flat solar collectors for forced circulation system, available with gross area of 2 m2 (CSP21) and 2.5 m2 (CSP25) of gross floor area.
In the collectors CSP21 and CSP25 the copper absorber (thickness 0.2 mm) is not simply painted but made with a selective layer TINOX that provides a high degree of absorption combined with a very low emissivity of thermal radiation.
The heat generated in the absorber, is then transferred to a carrier liquid that flows in special copper tubes ultrasonically welded on the copper foil.
Advantages:
Quality: high yields and choice of appropriate materials
Functionality: weighted size, structure and special engineered
Reliability: choice of construction, assembly and erection optimized
Low pressure drops
Rear insulating mineral wool
Absorber with selective treatment
High efficiency.
