The Vitosol 300-TM is currently the only collector on the market that can be installed horizontally (max. 3 degrees tube incline) and includes ThermProtect automatic temperature-dependent shutdown. It prevents overheating of the collectors when no heat is drawn off and there is a high level of insolation. The Vitosol 300-TM is therefore also suitable for buildings that are not in use all year round, such as residential buildings during holiday periods.
Vitosol 300-TM
Vacuum tube collector
High performance vacuum tube collector with ThermProtect
Heat pipe principle
Highly efficient vacuum tube collectors based on the heat pipe principle
Efficient heat transfer
Duotec double pipe heat exchangers made of copper completely encapsulate the condensers

Vitosol 300-TM vacuum tube collector
The Vitosol 300-TM high performance collector is one of the most efficient models on the market and is particularly recommended for use in restricted spaces. The absorber angle can be adjusted by +/- 25 degrees to deliver an exceptionally high yield, even when the sun is in less favourable positions.
The collector can be installed and used in any position and is designed for use on detached houses and apartment buildings. It features ThermProtect automatic temperature-dependent shutdown, which is activated if heat draw-off stagnates for a long period whilst there is a high level of insolation.
The collector works according to the heat pipe principle, where the heat transfer medium does not flow directly through the tubes. Instead, a process medium evaporates inside the heat pipe and transfers the absorbed heat through condensation to the heat transfer medium via the Duotec double pipe heat exchanger. This method guarantees optimum heat transfer.
The Vitosol 300-TM is designed for an exceptionally long service life. This is thanks to its high grade, corrosion-resistant materials, including glass, aluminium, copper and stainless steel. The absorber is an integral part of the vacuum tube. This protects it from weather influences and contamination, and ensures high energy yields for years to come.
The above roof installation system with rafter anchors simplifies the task of securing the collectors. The rafter hooks and flanges are designed to be fixed directly onto the rafters, enabling the collectors to be perfectly integrated into any kind of roof cover. The two mounting rails also save additional time during installation.
In systems with multiple collectors, dark blue cover panels create a seamless visual transition between the collector casing and absorber surfaces. Retaining caps in the base rail, in the same colour as the casing, prevent the tubes from slipping. Should a service be required, heat pipe tubes can be replaced quickly and easily without having to drain the system, due to their dry connection.
