auroTHERM plus VFK 145

 

The auroTHERM plus VFK 155 flat plate collectors have a toughened glass for improved durability, and special anti-reflex coating for excellent solar transmission. The collector consists of a laser welded copper/aluminium grid with a high selective absorber coating and improved rear insulation.

The whole assembly is encased in a black anodised aluminium frame for a neater appearance. The collectors are available in two models that can be connected in series in horizontal or vertical orientation to suit the available roof space.
