Sustainable and efficient solutions, that is the strength of our expertise.

Sustainable sources of electricity generation are increasingly becoming the norm, just think of the many solar panels or windmills that are already shaping the landscape today. However, producing sustainable heat is not yet self-evident, even though our heat consumption is just responsible for two-thirds of total CO2 emissions.

Azteq's solar thermal installations offer a solution for this by using the power of parabolic reflectors. These make it possible to generate heat of up to 400 °C in a sustainable and financially feasible manner.

All the elements for an efficient system

The parabolic mirror

Azteq solar mirrors capture and concentrate the sunbeams because of their geometry to the same point.

The collector tube

The collector tube is located in the focal point of the mirror and absorbs the heat by means of oil.

The heat exchanger

The heat exchanger transfers the heat from the oil to the medium that is applicable in the production process.

The buffertank

If you do not use the captured head immediately, it can be stored in a buffer tank for later use.

The alternative source

In addition to solar mirrors, the heat system consists of another alternative source to capture sunless days.
Mirror technology

Our solar mirrors reflect seventy percent of the sunbeams collected to the same point. This high degree of reflection is made possible by a special coating that reflects the rays as much as possible and absorbs as little as possible. In addition, our mirrors move with the sun so that they make maximum use of the sunlight at any time of the day. To limit the impact on the environment as much as possible, the mirrors rotate towards the ground when it rains so that no water is collected.

Collector technology

The collector tube captures the heat and makes it mobile. For this purpose, the tube consists of three parts: a glass outer tube, a metal inner tube through which oil flows and a vacuum between the two parts. The inner tube uses an energy-absorbing coating in order to lose as little heat as possible. The oil in it has a high thermal conductivity to absorb the heat as efficiently as possible. Because of the vacuum and the glass outer tube, the whole remains cold to the touch, and therefore animal friendly.

Heat exchanger

This is where the magic happens. The heat exchanger ensures that the captured heat can actually be used. The heat exchanger transfers the heat generated by hot oil from the heat collector to the medium used in the customer’s production process. This can again be thermal oil, but also heat in the form of steam.

Buffervat

The heat itself lends very well to storage for delayed use, up to five times more than efficient than electricity. Azteq makes use of this property by installing buffer vessels that serve as a kind of battery. This allows you to use heat 24/7, even when the sun is not shining. This system is most efficient when you install a set of mirrors for storage.

Alternative Heat Source
Alternative heat source

Despite having an average of 1300 hours of sunshine per year in Europe, there are of course days on which the sun mirrors cannot capture direct sunlight. As a result, they will not be able to generate the necessary heat. Azteq solar mirrors will therefore be installed in combination with an alternative heat source each time. This can be done with your current gas installation, but also with sustainable alternatives such as biogas. The heat exchanger will then be shared by both systems.

The advantages of our technology

Higher temperatures than other sustainable options

Until now, it has often been impossible for industrial applications to switch entirely to sustainable heat. Technologies such as geothermal or solar boilers with a capacity of less than 400 °C are unable to provide the necessary heat for a large part of the production processes. By optimizing the technique in which sunlight is concentrated, Azteq’s installations are able to produce heat of up to 400 °C. This is sufficient to support most of the production processes while not compromising on sustainability.

Truly CO2-neutral from installation onwards

Azteq’s solar mirrors are the only sustainable source of high-quality heat that is completely CO2-neutral from installation onwards. Other alternatives to the ecological production of heat are also responsible for CO2 after the development and installation of the system due to combustion reactions. With Azteq solar mirrors, this is not the case and CO2 emissions are limited to the production and transport of the systems.

Minimal impact on the environment

The impact of Azteq solar mirrors on the environment is almost non-existent. Thanks to vacuum technology, the collector tube remains cold enough to touch, the installations are completely odorless and noiseless, and the mirrors can be directed towards the ground in rainy weather, so that all the water reaches the ground.
