Schüco Slim V Plus
Flat Plate Solar Collector
The Schüco Slim V Plus is a highly efficient solar collector for thermal hot-water systems. The highly selective absorbent coating provides maximum energy gain, and optimal thermal insulation minimizes losses. The serpentine copper piping is designed to work with Schüco closed-loop, pressurized, no-bleed systems using non-toxic, freezeproof propylene glycol as a heat transfer medium. These collectors give the clean, attractive appearance of a high-tech skylight while the dark anodized aluminum frame blends beautifully with the home’s exterior.
Features
- Outstanding efficiency achieved with high selective absorber coating
- Low energy loss due to excellent thermal insulation
- Durable elegant dark anodized aluminum frame
- Low risk of leaking and superior flow control over conventional header/riser designs
- High degree of light transmission through low-iron glass
- Transportation to roof made easy due to lightweight design
- Sensor wells located on both sides of collector ensure precise resistance measurements
- Suitable for sloped or flat roof installation
- Serpentine piping, 1 connection on each long side for portrait orientation of collector
- Certifications: SRCC OG-100, CE, DIN EN 12975-2, DIN CERTCO, EC Guideline 97/23/EC
- 10-year performance warranty
