Product Details

The GK 3000 large scale collectors are manufactured in standard sizes of 5M² & 10M² and are available for installation schemes with a surface area above 80M². The special design of the absorber and the attractive performance data make these collectors ideal for large solar thermal systems. The optimized mounting system, which permits time-saving installation by crane, and simple connection considerably reduce the overall time and effort required.

Features & Benefits

Features of GK Series Collectors

  • Up to 10 collectors - can be connected in parallel or in series with each other with minimum pressure loss (Low Flow / Tichelmann)

  • Optimal stagnation and draining behaviour thanks to the serpentine absorber designed for large systems

  • Aluminium frame collector with a high degree of long-term stability satisfies all static requirements as per DIN 1055

  • Time-saving collector installation thanks to optimized support triangles with support rails as well as simple collector connections

  • Excellent value for money thanks to aluminium absorber with highly selective coating as well as minimum crane use and installation time to set up the system

  • Easy to service since glass covers and modules can be individually replaced
