AST-SOLAR-ABSORBER
SOLAR POWER
The entire solar radiation reaching the earth’s surface is approximately
ten thousand times larger than the actual energy needed by all of mankind.
We make a part of that energy available to you!
SOLAR-ABSORBER-Units – simply ingenious!

regulated correspondingly to the sun’s radiation intensity.
One square meter of installed absorber mats corresponds to an effective solar radiation absorption area of
1.523 square meters. The thermal performance capability is therefore enormous. 87% of the absorbed solar
energy is transferred to the water flowing through the absorber. Thus it is possible to heat large amounts of water
in the shortest amount of time using solar energy.
AST units are optimized for heating water up to a temperature of 40°C. Installing an AST-Solar-Absorber unit

costs tremendously. With the programmable AST-SolarController, that automatically operates the AST-SolarAbsorber to adapt to any change in energy input and output there, your energy gain can be further optimised and

SWIMMING POOL UNITS
SOLAR-ABSORBER-UNITS for Outdoor Swimming Pools
In central Europe the sun shines with the intensity of
about 800 to 1000 W/m2. This sun energy can easily be
utilised for the uncomplicated warm water heating of
your swimming pool with AST-Solar-Absorbers. One
square meter of absorber area delivers 250 to 350 kWh
of heat energy in the swimming season.

Especially for hotel pools and spa´s, an AST-Solar-Absorber-Unit offers enormous savings potential, since the
popular wellness facilities require a huge amount of warm
water. By using the optimized geometry of the AST
120-10 Solar-Absorber-Mats, the unit offers a large flow
