What is VentilAQUA Red

Efficient renewable energy solutions!

Renewable Energy Solutions

We have witnessed a continuous growth in energy consumption over the years caused by the increase in world population and by the economic and industrial development. This demand for more energy puts great pressure on energy resources from fossil fuels, which we all know are limited and will become increasingly scarce. On the other hand, rises the concern about our environment and climate changes leading to a demand for sustainable energy solutions. Aware for the need of changes, VentilAQUA created sustainable energy solutions, from renewable sources, contributing for a sustainable world.

Non-polluting sustainable and reliable solutions

The transition to a sustainable energy model, that respects our environment, is only possible with a clear commitment to renewable energies. This paradigm shift will enable a transition to a competitive low carbon economy. In VentilAQUA we believe this is the way to go. That is why we have created Red.

Easy to use and low-cost solutions

VentilAQUA Red is responsible for creating and delivering renewable systems adjustable to your needs. Yet, what all Red technologies have in common, is that since they are fueled by renewable sources, they allow for the generation of low-cost energy. Also, all VentilAQUA Red solutions come with both a reliability stamp and with the assurance to operate smoothly.

How we do it

Our technologies include photovoltaic and biomass systems, depending on your business surroundings, characteristics, needs, and wants.


Our top and breakthrough technologies at a glance

Photovoltaic Systems

Photovoltaic systems convert directly the solar energy into electric energy. Their use is unlimited and available to anyone, anywhere. Moreover, these solutions are rather long-lasting, presenting a useful life of over 25 years. Modular systems go from mW when considering consumer products, to highly powerful photovoltaic systems with Mw. If you make the best use of this technology, you will become the less and less dependent on fossil energy and will witness dramatic reductions in your electricity bill.


The self-consumption of photovoltaic energy is nothing more than the renewable system which privileges the consumption in the place where the electric energy is produced. With this solution it is possible to partially reduce or even eliminate the electricity acquired from the power grid. The facility remains connected to the public power grid ensuring the permanent availability of energy.
The self-consumption allows direct savings in the energy costs, through the instantaneous consumption of energy produced by the system. The technology increases the degree of self-consumption through the active control of loads. The storage also allows the increase of the degree of self-consumption, providing during the night the energy that has been generated in excess by the photovoltaic system during the day.

Off-grid Systems

In places where there is no electricity available, photovoltaic systems ensure fully energy supply. The systems are composed by the photovoltaic generator, charge controllers that ensure the correct power supply to the storage system, respective battery bank, and inverters, that in addition ensure the conversion DC to AC, allow the supply of any type of load, and manage the entire system, working as a network management centre. Typically, off-grid systems are used to bring power to remote areas, working with a basic system to meet the needs of an isolated house, up to larger systems that work as mini power distribution networks with enough power to feed entire villages.

Hybrid Systems

The hybrid system combines photovoltaic energy and electrical energy generated by another source like a diesel generator, wind turbine, or biomass generator. These systems assure a consistent supply without failures, mainly in places where climatic conditions do not allow the full operation of the photovoltaic systems. Hybrid systems are designed to make the most of the solar energy source. The high capacity storage battery answers to most of the energy needs, with a minimum use of the backup system.

Solar Water Pumping

Water is essential to all forms of life. In many remote locations, the traditional sources of energy are not available, or are unreliable, or even just too expensive to power a submersible or a surface water pump.
From the irrigation of fields, to the supply of remote houses or entire villages, solar water pumps are well suited and proven to meet water pumping needs, using solar energy. In fact, solar pumping systems are stand-alone systems operating with solar generators which may or may not use energy storage. They are the ideal solution where water is required when the sun is shining, or where it can be stored in a high location (eg in a tank), for further use.

Photovoltaic Systems for Water Treatment

Photovoltaic systems complement VentilAQUA BLUE solutions in the environmental sector, enabling the development of wastewater treatments that are energy autonomous and sustainable. The integration of photovoltaic technologies in our wastewater treatment plants allow us to offer environmental treatment solutions that work in places of difficult access or unavailable access to the power grid, or for installations supplied by the power grid, running at zero energy costs.
This way, we contribute to the preservation of the environment in a sustainable way.

Biomass Systems

The costs of producing thermal energy carry a significant weight in all sectors: industrial, services, and housing. Adding to that, the use of fossil fuels represents even higher costs and is a rather negative option from an environmental point of view. Thus, VentilAQUA red boilers are a good alternative for the traditional sources of energy, allowing the generation of heat in the form of hot water, at much lower costs, using biomass in its many forms.

What is biomass and in what forms does it present itself?

Biomass is the organic material coming from vegetables or animals, including organic residues. Among the major solid biofuels, we can highlight the olive pits, nut shells (almond, pine nuts), and of course, forest residues and residues from wood industry. Depending on the origin and the final conversion system, solid biomass can present itself in the market on various forms, being more common in the form of pellets, wood chips, sawdust and forest biomass.

VentilAQUA Red Boilers

VentilAQUA Red Boilers consist of pyro tubular heat exchangers with three gas passages. They present great combustion and conversion efficiency. Also, Red Boilers are solutions of simple maintenance, low investment costs, and extreme reliabililty. In fact, they run quite smoothly thanks to their very autonomous operation. Given their high potency, VentilAQUA Red Boilers become a particularly pleasing technology at District Heating and industrial systems.

Benefits of VentilAQUA Red Boilers systems

The boilers that currently use fossil fuels can be replaced by boilers VentilAQUA RED. This replacement allows significant reductions in the energy costs, with short payback periods. In fact, fuels derived from biomass allow savings up to 70%. Therefore, production activities with intensive energy consumption can largely improve their profitability with the conversion to VentilAQUA RED boilers.
There are already more than 700 units in operation, representing an installed capacity exceeding 700 MWth, which results in significant reductions of emissions of greenhouse gases and fuel costs.

We are committed to actively fight for climate protection and for the growth of renewable energy sources.
