The collector collects sunlight in front of the façade and protects the adjoining rooms from direct solar radiation. Due to the low thermal losses, solar heat with high temperatures (60-90°C) can be produced, which is then supplied to the building through the pipe system integrated into the façade profiles, to heat drinking water and produce heat or provide solar cooling.
A slight proportion of the sunlight penetrates the perforations of the reflector into the building, providing even and low-glare lighting of the room and visual transparency for the office users.
By making the right choice for the perforations of the reflector, both the solar protection which is important for the office building and the high level of collector efficiency are ensured. The high level of thermal insulation on the glass façade ensures a small level of energy consumption during the heating period. The opening window sashes on the façade make it possible to easily clean the glass surfaces.
Heat exchanger for shower cabins
Main innovation is the use of an aluminium tube in direct contact with the drinking water. The specially developed coating prevents any migration of aluminium into the drinking water.
Douche-WTW is a simple tube which can be installed in the wall below the shower cabin. The excellent thermo conductivity of aluminium recovers the heat of the wastewater which is re-used. This will save you 50% of energy each time you shower.
