Solar heat exchangers

– PVT pannels
– Absorbers for flat plate solar collectors
– Thermodinamic pannels

Thermal Energy Harvesting

Roll-bond heat exchangers are applied in solar thermal collectors and hybrid PVT modules, where large surface coverage and uniform heat extraction are critical. The flat aluminium design enables compact integration and supports scalable collector concepts for industrial and district heating applications.

PVT pannels

Hybrid photovoltaic-thermal (PVT) panels can be produced according to project-specific requirements, including customized geometry, hydraulic interfaces, and thermal performance targets. This enables tailored integration into various PVT module concepts.
