The large-area high-performance collector WGK AR with single or double glazing - ideally suited for solar process heat and local as well as district heating support.
- Straightforward connectivity
95 - 120 m² of total collector surface can be directly coupled as a continuous row. No additional piping required, low pressure loss. Both diagonal and single-sided connection are possible. - Highest efficiency
A self-emptying serpentine absorber with excellent stagnation characteristics ensures trouble-free operation.
- Perfect for high temperature operation
Single or double glazing with double-sided anti-reflective glass coating ensures superior performance with medium and high temperature applications. Combinations are also possible. - Time- and cost-saving assembly
Collectors prepared for rational crane assembly. Significantly reduced installation times in combination with the sophisticated installation systems for free-standing installation and on-roof installation.
Up to 10% more solar yield!
