The sun ventilates fully automatically and with an energy gain

Put an end to dampness and mould


SolarLueften KaeseglockeNot used in winter

Many holiday and weekend homes, club houses as well as studies and guest rooms are not constantly used in the winter and are therefore not regularly heated and ventilated. The rooms and the stock become damp, moist and mouldy. With a solar caretaker from Grammer Solar such problems become a thing of the past.

Dampness and mould

A musty smell is not only unpleasant but also extremely unhealthy if mould spores wreck havoc. Furthermore, the dampness results in expensive damage to textiles, furniture and also the structure of the building. Only adequate heating and ventilation - with SolarAir for example, can provide a permanent remedy for this.

Fresh air for healthy living: Ventilation is not a luxury

SolarLueften GeldPoor air is unpleasant and unhealthy. If there is insufficient ventilation, the air does not contain enough oxygen; unhealthy outgases accumulate from furniture and textiles. Problems with dampness and mould develop.

Energy saving and quality of living

In general, not only the consumed air  escapes from the building but also valuable heat. Therefore, energy-saving buildings have to be build as insulated as possible. Nowadays, windows in new buildings are very good insulated so that no air can escape from indoors. This can cause dampness and mould inside the room if the windows aren‘t constantly opend for ventilation. Alternatively, a ventilation system can be installed - a solar energy integrated ventilation system would be ideal.

Legal provision

In most of the European countries a minimum exchange of air in new buildings and during renovation projects must be guaranteed. 

SolarVentilation: simple...and efficient


As soon as sufficient sunlight falls on the collector, a ventilator starts. Fresh outside air is filtered and drawn in through the heat -insulated air collector. In doing so, the air heats to up to 40°C. (Air heating average in the winter ~17°, during the changing of seasons ~30°). The warm air now enters the house via an insulated pipe. With only 1m² of collector surface area, 15m² of living space can be well ventilated and kept dry in Germany (in the south up to 30m²). Mould and damage caused by dampness are a thing of the past. In exchange for this, the interior air is completely exchanged on average 1-2 times on winter days or 4-10 times in spring and fall.

Even when there's no-one at home

A SolarAir installation by Grammer Solar is fully-automatic and reliable in operation. Freezing, leaking and evaporating are completely impossible with air collectors. If no heat is required on sunny days, the installation automatically switches off. Change the filter once a year - apart from this there are no other operating or maintenance costs.

heat simply and cost-effectively

A simple way to heat and ventilate with the power of the sun:


betriebsfertig

Heating and ventilation made easy with solar energy: fresh outside air is filtered and drawn in through the heat insulated air collector made from aluminium. In doing so, the fresh air is heated and channelled into the house via an insulated pipe. When the desired room temperature is reached, the system automatically switches off with the help of a thermostat. Even when there's no-one at home, the indoor climate is dry and healthy. Twinsolar compact is a self-sufficient system and doesn't need to be connected to the electrical grid.

Always on the sunny side

The solar collectors can be mounted vertically or horizontally, facing the south, south-east or south-west. They are fixed to the roof, to the facade or even to a balustrade - wherever the sun reaches the building most effectively. When selecting the mounting site please note that the shadow projection in the winter is greater than in the summer due to the more inclined angle of the sun. An angle of at least 45° (or even better 60°) or facade mounting is required to allow the snow to slide off the collector in winter.

Tailored assembly packages provide for a flexible and simple installation of the systems. The heated fresh air then reaches the interior of the house through an easy to lay pipe.
