The SCF-20/4B A is a high-performance sealed solar collector designed for thermal solar systems. It features a pre-painted galvanized steel profile, ensuring durability and resistance to environmental factors. The collector boasts a 2 square meter absorber surface with a highly selective TiNOx treatment, which allows for an impressive 95% absorption rate of solar radiation. This advanced treatment minimizes heat loss and maximizes energy capture. The insulation is provided by 30 mm of glass wool, further enhancing thermal efficiency and reducing heat dissipation. With a stagnation temperature of 180 °C, the collector is built to withstand high temperatures without degradation. It offers flexible installation options, allowing up to 10 collectors to be connected in series vertically. The SCF-20/4B A is backed by a 5-year warranty, ensuring long-term reliability and peace of mind. It is also Solar Keymark certified, guaranteeing its compliance with European quality and performance standards for solar thermal products. This collector is an ideal solution for sustainable heating and cooling applications, contributing to energy efficiency and environmental protection.
