Thermal Solar Collectors
Klymaa’s high-performance thermal collectors relay on the combination of black thermal absorbers and revolutionary nanocomposite multilayer films of metal oxides on extra-white solar glass. This nanocomposite films are deposited by magnetron sputtering in a high-vacuum chamber. To harvest the energy of the sun, Klymaa’s thermal collectors surround the building’s exterior envelope (roof and façades).

Coloured Glass Cladding
With their coloured finish Klymaa’s thermal collectors can replace conventional glass claddings, providing architects and engineers with new sustainable design options for the façades of buildings. Thanks to the high-tech nano-coating of Klymaa’s collectors the solar radiation can pass through the glass and can be absorbed by the thermal collector, while it is opaque to the human eye.

Selective Filter
The nanocomposite multilayer films of Klymaa are selective filters for solar radiation. They transmit all the incoming solar radiation and at the same time reflect a very small band in the visible range of the solar radiation, to provide the colour impression for the cladding.

Water Circulation
The hot water generated in the thermal collectors by absorbing the solar radiation can be used as domestic hot water, for heating of the building or it can be transferred into cold air for cooling.

Sorption Chiller
Sorption chillers use the physical or chemical process of adsorption or absorption to convert heat into useful cold. They are based on a thermal cycle process that requires a heat source (hot water from collectors) to provide the necessary energy to drive the chilling process. In the chilling process heat / energy is withdrawn from a cold liquid by which it cools down further. This cold liquid can then be used to cool down air or directly in radiation ceilings for the cooling of the building. Further, extra heat at medium temperature has to be removed from the system to complete the thermal cycle.
