Flat collector with the allocation for the horizontal assembly

Collectors type  ES2H/2,65S; ES2H/2,65B  are proposed in two colour versions:

- ES2H/2,65S – in natural aluminium colour
- ES2H/2,65B – anodized in dark-brown colour

Advantages of using collector with meander absorber:

• 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 Keymark
