Flat collector ES1V/2,65

Flat collector about the area 2.65 m 2 for the vertical assembly. The structure of the collector is leaning against the double harp absorber.

Collector of series E S 1 V/ 2,65 are offered in two colour versions:

ES1V/2,65S – colour of natural aluminium
ES1V/2,65B – collector anodized in dark- brown colour

Advantages of using the double harp absorber:

• the intake of the factor and the take-off are on one level. Such a solution is reducing the number connector pipe additive only to two what the quantity of connecting elements is making smaller as well as he is shortening the time of the assembly..
• linking Ensol collector in the battery doesn’t require balance beam plumbing because collector are being linked in series and because of that the flow in each of them is identical.
• in the case if some of collectors in the battery was disabled (e.g. obstructed) it would be while starting the installation it at once visible through the lack of the flow of the factor in the entire installation (series connection)..
• the flow in the collective pipeline is equal of the nominal flow for one connector what is important solar installations because is reducing capital costs (smaller diameters of pipelines, smaller circulation pumps, and consequently also less of solar liquid)..
