Sustainable

Local waste heat recovery and renewable heat based cooling technology

ADSORPTION CHILLER

Effective cooling from waste heat

We add local value to heat coming from the sun, geothermal or from industrial processes, because with our machinery solution it is used for cooling purposes at low running costs.

Advantages

The future machine technology for cooling systems

The fight against global warming can’t be fought with traditional climatisation technologies, so we need a green, sustainable, adsorption technology based cooling technology, that:

Doesn’t contain hazardous materials

Is easy and safe to operate

Has a very low primary energy need (electricity)

Low maintenance, decades-long lifespan

ESG-friendly, competitive, and profitable investment

Pays off better than other widespread technologies in 5-7 years.

Actions

What we do

We offer innovative solutions for waste heat utilization in manufacturing, energy, and building operations. With customized mechanical and payback plans, along with our proprietary adsorption chillers, we help our partners create sustainable and cost-effective cooling systems.

Partner acquisition

We are looking for locations and partners in manufacturing industries, the energy sector, building facility and urban management, where waste heat is available even from renewable resources like geothermal or solar heat.

Manufacturing

Based on client orders we plan to ship globally the ADChiller adsorption chiller machines in different sizes, designed by us with proprietary know-how but also based on licensed japanese-american technology. Our first series machines will be manufactured and assembled in Hungary within the EU starting from 2025.

Plan development

Based on future client needs, in cooperation with our global and local technology partners, we make site specific machinery investment and operation planning, including lifetime cost and return calculations (TCO), including any additional technology needs.

Remote monitoring

After deploying the ADChiller machines at our client site we continuously monitor it’s operation via IoT data connection to our secure servers. This way we keep the controller software up to date, and with our service partners we provide the necessary cost-effective maintenance, so that the planned, multi decade expected operational lifespan of ADChiller machines is truly met.

UN Sustainable Development Goals

Wide-ranging impacts

The growing cooling demands and energy prices may lead to energy poverty, which is why our goal is to reduce the energy consumption for industrial, public, and later residential cooling by up to 70-80%. In the IT sector (AI, HPC), traditional air cooling accounts for nearly 30% of the energy consumption of computers, which can be replaced with adsorption cooling, resulting in significant savings.

To reduce hunger, we would develop a cost-effective grain drying solution, alongside a research and development focus on clean drinking water production. Compared to current natural gas-based heated solutions, cooled drying could globally reduce the total cost of grain. As a result, the cost of animal products could also decrease, as heat-based drying currently accounts for 5-25% of the grain's moisture content, depending on the level of moisture.

We contribute to health and well-being by making cooling/air conditioning affordable, reducing the number of deaths during heatwaves. Additionally, our machines do not contain hazardous materials, preventing harmful substances from being released into the environment, unlike the gases used in traditional air conditioners (such as ammonia, CO2, etc.).

Our technology can also contribute to the production of clean drinking water, as one of our future research and development directions involves a pilot and test unit designed for the energy-efficient extraction of atmospheric moisture (especially in coastal areas).

We contribute to affordable and clean energy by utilizing waste heat for cooling purposes, thus reducing the cooling electricity demand by 70-80%. With our adsorption chiller, we can significantly increase the efficiency of gas turbines (by 8-10%) through pre-cooling of the combustion air (achieving a higher oxygen content and density), which will not only lower the operational costs but also reduce the carbon footprint on the energy production side.

During the development of our cooling technology, we are organizing an ethical supply chain, which will enable the creation of sustainable and higher-value-added jobs at our partners' facilities, starting in the EU and later expanding globally.

In terms of industrial innovation and infrastructure, our technology alone brings the development of a supply chain, and in addition, it makes many manufacturing industries more competitive through cost-effective and sustainable cooling solutions. With our technology, more industrial production can remain cleaner and more sustainable within the EU, enabling it to compete globally (such as in the pharmaceutical, chemical, food, energy, and even automotive industries).

We can contribute to sustainable cities and communities by combining adsorption cooling at the building block scale with district heating. We also reduce the number of urban heat islands by replacing the outdoor units of traditional compressor-based air conditioners with a cooling tower located elsewhere, which efficiently performs the heat rejection function linked to adsorption cooling.

We contribute to responsible consumption in terms of cooling demands by utilizing locally available waste heat, which, in many cases, is still not addressed by other technologies. This approach not only reduces energy consumption but also promotes the efficient use of resources, further enhancing sustainability.

Our goal is to reduce the carbon footprint of electricity consumption for cooling needs. With ADChiller chillers, we can also lower the carbon footprint on the energy production side, such as by cooling gas turbines and nuclear power plants. For residential use, we aim to develop solar collector-based adsorption chillers, with the costs covered through the sales of our industrial machines and capital investment, thereby reducing the carbon footprint of households.

To protect the oceans and seas, we plan to use our adsorption chillers in maritime applications, which presents a significant global market opportunity due to the industrial scale and heat emissions of ship engines. By addressing the cooling energy needs of ships (such as cargo cooling, etc.), the use of adsorption cooling will reduce the harmful emissions from maritime shipping.

The protection of terrestrial ecosystems is supported by our advanced adsorption chillers, which do not contain environmentally hazardous materials. The complete recyclability of the machines is also ensured, whether through refurbishment or raw material-level recycling.
