Large Scale Collector GK 3000USP‘s

• Advantages by using big solar thermal systems– Manifolds 28mm– Up to 11 modules (110m²) in parallel connection possible

based on minimal pressure losses• Easy installation reduces costs

– 3 triangles for 10m² reduces thepreparation time on the roof

– Pre-mounted fastening with lay-on profilesallows a minimal crane endurance

– Simple connection of collectors based onintegrated anti-twist protection

• Attractive System-Output– Low pressure losses– High efficiency

• Optimal shut-down behavior (Serpentine-Absorber)• Good price-/efficiency relation

– Output/m²-price– Integral costs of solar thermal system

• Excellent quality– Statics– Optical design

• Easy Service– Glass and module can be replaced separately
