ACSZeroMO system was originally designed with a military purpose. Therefore, it had to comply with an endless list of requirements based on:

  • Reliability
  • High efficiency
  • Robustness and high quality of components
  • Resistance to vibrations, shock, water, dust and extreme weather conditions
  • Low or no maintenance
  • Scalable
  • Long useful life
  • Operation in extreme conditions
  • Simple use
  • Speed in commissioning and decommissioning
  • Easy to transport in different media
  • Moderate price

This long list of requirements is what we later transfer to the equipment for civilian use, obviously it is not necessary to apply military grade protections, which lowers the cost.

Adaptations have even been made to improve the production capacity of the system, since in civil environments the security requirements are reduced in favor of the productivity of the system.


How does it work?

Although the basic technology is explained HERE, the container version has some special features that give it certain aspects that are somewhat different.

The main energy generation system is state-of-the-art photovoltaic panels. Which are deployed from the container itself, or from an accessory container.

We offer various deployment options to suit your needs. Once the unit is unloaded, the panels can be deployed either independently or as units that are folded on top of the container itself (in this configuration, it is the High container type, either 20 or 40 feet) or an additional container.

Of course, there are other options, such as solar thermal collector system units that use parabolic collector systems, or different photovoltaic panel mounting systems. Even if the client already has photovoltaic installations, it is as simple as connecting the system to the power supply of the PV panels.

We also offer underground storage systems, which are quite useful for fixed installations. This significantly increases the thermal storage capacity of the system and the time it can operate WITHOUT solar radiation. Very useful in areas with winters with little solar footprint.

The photovoltaic panel deployment system can offer various options depending on the client’s needs, available space, or even if the unit will be in a covered area and the photovoltaic panels must be in another area.

In the absence of solar radiation, the system utilizes stored heat to maintain a continuous flow of hot water. It’s analogous to having a battery that stores energy, but instead of electrical energy as in a regular battery, we store thermal energy.

This energy is used on demand. We essentially store solar energy without the need for expensive or complex systems like those used in large-scale solar thermal plants, which liquefy sodium to use it outside of sunlight hours. ACSZero technology is what has allowed us to make a first-class technological leap, enabling the generation of high-efficiency thermal storage cells.



The ACSZeroMOD system can operate completely off the grid, meaning without any connection to external energy sources. Depending on the geographical location, we can increase or decrease the number of photovoltaic panels to ensure 100% delivery 24/7.

The system is designed to work with freshwater. If you wish to use brackish or saltwater, please contact our engineering department to make the necessary modifications to the system.

In highly challenging environments with low sunlight (near polar regions), additional storage tanks, such as underground tanks, or specific storage containers through our e-depot system, may be required. We can also utilize other heat sources, such as diesel or gas generators, to capture and store thermal energy that would otherwise be lost to the atmosphere. In extreme cases, please consult with our engineers to design the most suitable system for optimal operation under extreme conditions.

If the system is also going to be used for heating, it is important to adjust the water flow rates per hour to ensure there are no temperature drops at any time.

Solar concentrators and other technologies

ACSZeroMO can also operate in conjunction with solar concentrators. If you have an existing installation of this type or if the system will be used in a fixed location, we can also work with this type of direct thermal energy.

In cases where you have power plants that run on fossil fuels or biomass, we can also recover the heat released into the atmosphere to store it and use it in the hot water generation process.

Similarly, we can also operate the system in a hybrid manner, utilizing a combination of different energy sources to create a scalable thermal storage system. This system is also suitable for maritime applications and for centers located in extreme environments, such as high-altitude regions or polar bases.

If you have existing underground storage facilities, we can also inject thermal energy and use them as secondary storage in case of demand peaks that could exceed the system’s design capacity.

In this way, we can utilize facilities of this type, whether existing or new.

In essence, we can interact with various generation and storage systems to function as a logical thermal distribution, generation, and storage node.

Furthermore, it can also interact with traditional systems, resulting in a system that is operable in all types of environments, connected to various systems individually or simultaneously. It’s like a Swiss Army knife for hot water production.

Remote control and management

In addition, we can access all system information remotely, enabling us to make fine-tuned adjustments even from a distance.

Through the management system, we can remotely receive information from all ACSZeroMO measurement systems and sensors, activate and deactivate, modify values, and in essence, have absolute control over the management of our system.

Return of investment

Returns on investment in domestic hot water equipment can vary greatly depending on multiple factors. The type of installation, the type of fuel, the age, the maintenance costs, subsidies or grants, and so on.

Overall, modern equipment with high-efficiency combined systems begin to pay for themselves in the most advanced systems in about 4 years (not counting subsidies). A gas boiler system pays for itself, given its costs, but the return on investment is difficult to calculate, as it must be considered in conjunction with the rest of the investment. Traditional equipment has become a necessary expense but with a difficult return.

ACSZero technology-based systems have a shorter ROI period, but the time can vary between 6 and 18 months depending on the type of installation and its characteristics (not counting subsidies).

For ACSZeroMO systems, the ROI time can also vary depending on usage. For installations with continuous use, the ROI times will be identical to the standard ACSZero system, that is, from 6 to 18 months. If the installation does not have continuous use, the payback time will obviously vary depending on the time of use, in which case we will calculate the ROI time based on the time of use and the unit’s displacement costs.

One of the advantages of this system is that it can be in one place for 4 months, then moved to another, and then to another. So its profitability can also be different. If it is necessary to take this system to a disaster or remote area, where energy costs can skyrocket, its ROI will be considerably shortened.

To better understand this situation, let’s consider an example from the military sector, the origin of this technology. Imagine you have a base in Afghanistan and use diesel generators. This means you need logistics to transport the diesel to your base, which involves very high logistical costs.

If you add the cost of fuel storage facilities and associated security costs to the logistical cost, the price of that fuel will multiply exponentially.


Let’s visualize the situation. Military bases in Afghanistan received their fuel from Pakistan. The fuel was unloaded at a port in Pakistan, loaded onto trucks, and transported across the country. Upon reaching Afghanistan, the trucks had to form a protected convoy to ensure safe delivery to their destination.

Can you imagine the final price per liter of fuel? It was absolute madness. This aspect makes the ROI of our system extremely short, as we are dealing with an exceptional situation.

Here we can see real images of the logistics of transporting fuel to the bases in Afghanistan. To prevent the situations that you can see in the images from happening, the convoys had to be escorted, in small groups, and with air support, usually helicopters. Can you imagine how much a liter of diesel cost at the Spanish base in Herat? Absolutely exorbitant.

In other words, in special situations, the ROI of the ACSZeroMO system can be incredibly short. Or in humanitarian action situations, it can simply be a tool that saves lives, and in those cases, as you know, price doesn’t matter.

Remember that you can use hot water for heating, laundry, cleaning and disinfection, personal hygiene, or even industrial processes.


The system’s scalability is as simple as adding units. In other words, if one unit produces 50,000 liters of hot water per day, then two units will generate 100,000 liters.

In special installations, customized systems can be created to increase thermal storage capacity, simplifying the installation process.

Due to the system’s versatility and flexibility, it can be adapted to practically any need. Even in environments with variable flows, meaning if there’s a need to increase production at a certain time of the year, you can simply add units temporarily.

This can be very useful in industrial systems with non-linear demand. If, during a certain season, you require double the flow rate, you can temporarily add an extra unit for a few months.

The ability to move units provides tremendous logistical power. It’s like having a truck loaded with energy that recharges itself automatically.

This mobility, coupled with scalability, gives the system unique capabilities that allow it to operate autonomously. Whether for mobile installations, increasing capacity during production peaks, or simply installing a system that requires minimal installation, is operational quickly, and has no impact on your existing facilities.

Imagine you have a rented warehouse. When you move to a new facility due to your company’s growth, you can quickly dismantle and reassemble your hot water system, making the process fast, affordable, and efficient.

In summary, a system that can meet your hot water needs, whether they are permanent, temporary, mobile, or multiple and variable.
