- Sustainable and environmentally friendly – No harmful refrigerants required.
- Energy efficient – Minimal electricity costs compared to air conditioning.
- Cost-effective – Lower investment and maintenance costs.
- Effective for large spaces – Ideal for industrial halls, warehouses and production facilities.
- Fresh and healthy air – Continuous supply of purified, cool air.
With adiabatic cooling, you benefit from an efficient and future-proof cooling solution that not only improves the indoor climate, but also reduces your energy costs. Request a quote for a customized proposal.
What is adiabatic cooling?
Thousands of years ago, the Egyptians discovered the power of evaporative cooling. By evaporating water in porous clay pots, they effectively cooled indoor spaces. This age-old principle forms the basis of adiabatic cooling, a technique that has been increasingly used in recent decades as a sustainable alternative to traditional air conditioning. Adiabatic cooling, also known as evaporative cooling, reduces the air temperature through water evaporation. The energy required to evaporate water is extracted from the air, causing it to noticeably cool.
Two forms of adiabatic cooling:
- Direct evaporative cooling – Water is atomized directly into the air, cooling it immediately.
- Indirect adiabatic cooling – Air is cooled via a heat exchanger, without moisture entering the air flow directly.
You can read more about the two forms below.
Direct adiabatic cooling: efficient and energy-saving cooling
Direct adiabatic cooling involves spraying water directly into the room using nozzles. The evaporation causes the air to absorb moisture and lower the temperature, without requiring much energy. For example, a 10,000 m³ hall requires only 1 kW of energy per hour – a fraction of the consumption of traditional air conditioning. Two methods for direct adiabatic cooling:
1. Misting with nozzles
Water is atomized into the air via high-pressure nozzles and fans.
This evaporates immediately and lowers the temperature without additional air resistance.
2. Cooling via saturated material
Air is drawn in through a water-saturated material that can absorb and release a lot of moisture.
A pump and pipe system keep the material wet.
Water evaporates in the air flow, which cools it without additional energy consumption.
- Extremely energy efficient – Cools large halls with minimal power consumption.
- Natural cooling – No refrigerants, environmentally friendly and sustainable.
- Healthier indoor climate – Adds moisture to dry air and reduces dust formation.
Indirect adiabatic cooling: cooling without additional humidity
In indirect adiabatic cooling, the cooled air is not introduced directly into the room, but is transferred to a separate air stream via a heat exchanger. This makes it possible to cool rooms without increasing the relative humidity, which is essential in environments with specific climatic requirements.
How does indirect adiabatic cooling work?
- An air flow is humidified and thus cooled.
- This cold air flow is passed through a heat exchanger.
- The supply air takes over the cold without absorbing any moisture itself.
- The result: effective cooling without additional humidity in the room.
Advantages of indirect adiabatic cooling
- Suitable for moisture-sensitive areas – Ideal for data centers, laboratories and production areas.
- Energy efficient – Cools without refrigerants or high electricity costs.
- Environmentally friendly – Sustainable alternative to traditional air conditioning.
- Comfortable indoor climate – Cool, dry air without condensation problems.
