Flat collector ES2V/2,65
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 ES1V/2,65 are offered in two colour versions.
ES2V/2,65S – colour of natural aluminium ES2V/2,65B – collector anodized in the dark-brown colour
Advantages of using the meander absorber:
- Increased ability to adopt the warmth.
- ability to self-venting
- meander collectors can be joined into large batteries to 10 collectors preserving the safety of even flows through single manifolds and in the process guaranteeing the full receipt from the entire battery
- For the battery of 5 collectors is a possibility of connection one side what is reducing solar installation costs and is also reducing losses of the warmth of the installation thanks to short segments of wires
- 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 10 collectors in the battery
- Mark is holding the solar key mark
