Schüco Performance Series
Flat Plate Solar Collector CTE 220 CH 2
Performance for Large Systems
The Schüco Performance Collector Series was specifically developed for large solar thermal installations. A unique proprietary thermal conduction technology improves the heat transfer between the absorber and the serpentine pipe work, resulting in higher output. The Schüco Performance Series collector is constructed using a serpentine-manifold hydraulic configuration which allows up to 16 collectors to be connected in series with minimal pressure losses. The Schüco performance collector design reduces overall system pipe size and pumping station requirements, as compared to conventional header-riser designs. The benefits are reduced installation cost and time.
Key Features
- Integrated sensor wells provide precise temperature measurements
- Unique 360° bonding technology provides high efficiency thermal transfer
- Serpentine design allows the collector to manage all climatic conditions resulting in high system reliability
- Hail resistant clear glass with exceptional light transmission for high solar outputs
- Long life span and durability due to temperature and corrosion resistant materials
- Up to 16 collectors can be interconnected in a row
- Optimized stagnation behavior due to reliable collector evacuation
- Quick and easy installation
