VACUUM TUBE COLLECTORS

Calpak Vacuum VTN Series

VTN Series Vacuum Tube CollectorThe ideal solution when real efficiency is what matters. The parabolic reflector maximizes absorption of direct and diffused solar radiation. Moreover, thermal losses are minimized due to the vacuum in the selective tubes and the strong header insulation.

  • Highly efficient evacuated tube collector using U-shaped copper tube with inner aluminum fins
  • Highly selective coatings on glass tubes maximizes absorption while minimizing radiant heat loss
  • CPC reflector for optimal performance even on partly cloudy days
  • Black header made of anodized aluminum with expanded polyurethane and fiberglass for strong insulation
  • Easy to replace vacuum tubes
  • Light weight for easy handling during installation
