Laboratory glass: Solar collector module - German/German

The solar collector module made of vacuum all-glass tubes is a development of the Wertheim-based company Lenz Laborglas, which donated it to the Glass Museum in 2007. The state-of-the-art module effectively contributes to reducing the daily energy demand.

A solar tube that dates back to the early days of solar technology is also in the possession of the glass museum. This was donated by the Wertheim company Ludwig Schneider in 1978. At that time, Schneider was commissioned by the company Luz Industries Israel to develop a machine with which the vacuum density of the glass-metal connection could be controlled.

The collector-tube module from Lenz Laborglas uses solar energy to heat water for the bathroom and heating. The sun heats the collector, which transfers the heat to a liquid in the tube system. There, the liquid, which has a temperature of up to 90 degrees Celsius, circulates between the collector and the storage tank. New - in contrast to the conventional metal-glass connections - is the glass-glass connection between the cladding and absorber pipes patented by the Lenz company.

A few years ago, the question arose as to how the function and significance of this high-tech product, which points the way forward for energy research, could be communicated in a clear and understandable way, especially to children and young people. Together with the Wertheim/Lindelbach secondary school and the Ochsenfurt playground, this resulted in the "mobile energy trail" with 28 interactive stations. The "mobile energy trail" can be borrowed. If you are interested, please contact the museum ticket office.

 

Laboratory Glass: Solar-Collector Module - English

The Wertheim company Lenz Laboratory Glass developed the solar collector module made of vacuum all-glass cylinders and donated it to the Glass Museum in 2007. This ultra-modern module is an effective tool for reducing daily energy requirements.

The museum also has a solar tube that dates back to the early years of solar technology that was donated in 1978 by the Ludwig Schneider Company in Wertheim. Schneider had been contracted at the time by Luz Industries Israel to develop a machine that could measure the strength of the vacuum seal that joined glass and metal.

The Lenz laboratory glass company collector cylinder module uses solar energy to heat water for the bathroom and central heating system. The sun warms the collector, this transfers the warmth to a liquid in the cylinder system and this fluid that can reach temperatures of up to 90°C circulates between the collector and the storage tank. New - in contrast to the conventional metal/glass joints the Lenz company patented a glass-glass joint between the jacket cylinder and the absorber cylinder.

A few years ago the question was posed as to how the significance and function of this precedent-setting high-tech product in energy research could be mediated - to above all, children and teenagers. This developed into a project with the Wertheim/Lindelbach secondary school and the Ochsenfurt Play Construction Area that produced the "Energy mobile course" with 28 interactive stations. The "Energy mobile course" is available for loan and you can find out about it at the museum desk.
