Flat collector ES1V/2,0
ES1V/2,0 – Flat collector about the area 2.0 m 2 for the vertical assembly. The structure of the collector is leaning against the double harp absorber.
Collector of series ES 1 V/ 2.0 are offered in two colour versions:
- ES1V/2,0S – colour of natural aluminium
- ES1V/2,0B – collector anodized in dark- braun 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 collectors 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 collector what is important solar installations because is reducing capital costs (smaller diameters of pipelines, smaller circulation pumps, and consequently also less of solar liquid)
- The high permanence and the airtightness of the casing resulting from applying the technology of the bent profile
- The high safety of the exploitation and the great permanence thanks to high quality, corrosion-proof materials.
- High efficiency thanks to covering the high selective absorber
- Sealing panes immune to atmospheric influences and the ultraviolet
- Bottom wall made of the metal sheet aluminium, immune to the puncture
- Available in attractively-priced solar packages from 2-coils with heaters of warm functional water
- Possibility of applying to 5 collectors in the battery
- Mark is holding the solar key mark
