Description:
The Vitosol 300-TM Typ SP3C is a high‑efficiency vacuum tube collector operating on the heat pipe principle with automatic temperature shutdown (ThermProtect) for high operational reliability. The collector is designed for heating drinking water, heating water, and swimming pool water via heat exchangers, as well as for process heat generation. Each vacuum tube contains a highly selective coated absorber that ensures high solar absorption and low thermal emission. The collector is available in three sizes: 1.26 m² (10 tubes), 1.51 m² (12 tubes), and 3.03 m² (24 tubes). The vacuum tubes can be rotated by 25° for optimal solar orientation without shading. The collectors can be mounted on pitched and flat roofs, façades, or free‑standing.
