Cooling & Humidification

Adiabatic cooling systems generate up to 95% of their cooling performance through the evaporation of water. This allows for a significant reduction in temperature with relatively low water consumption. By evaporating just 1 m³ of water, these systems can produce up to 695 kW of cooling power.

Water as a refrigerant

Water, the fundamental medium behind adiabatic cooling systems, is one of the planet's most powerful and commonly used coolants, owing to its exceptionally high latent heat of vaporization. The higher the latent heat of a substance, the more heat it can absorb from the air during the evaporation process.

In addition, water possesses other valuable properties that make it an invaluable resource.
No ozone depletion potential
Zero CO2 equivalent
Not poisonous
Non-explosive & non-flammable
No contribution to global warming or greenhouse effect
Re-enters the natural cycle through evaporation

How does adiabatic cooling work?

Our PreCooll adiabatic pre-cooling system utilizes direct adiabatic cooling technology, designed to be easily installed on any type of air-cooled condenser. It provides a sustainable and highly efficient solution for addressing your cooling requirements.
Free cooling
Even in transitional seasons, cooling may be necessary. Despite cooler outdoor temperatures, indoor conditions can become uncomfortable due to sunlight streaming through windows and the heat generated by machinery. Unlike traditional air conditioning systems, Oxyma’s innovative technologies leverage outdoor temperatures for natural free cooling, using only fan operation to cool the space with minimal energy consumption.

Direct Adiabatic Cooling

15-40%
Energy savings
In a direct adiabatic cooling system, hot outdoor air is forced through a wet evaporative cooling media using an electric fan. A circulation pump continuously moistens the media by supplying water at the top. The cooled air is then directed into the building.
The cool air output can be reduced to 70-90% of the wet-bulb temperature, depending on the efficiency of the evaporative media (i.e., evaporation efficiency). The air temperature can be 10-14°C lower than the ambient temperature (e.g., 22.4°C at an outside temperature of 36°C), but the relative humidity remains high (up to 90% RH). Therefore, direct adiabatic cooling is not recommended for cooling workplace or residential environments.

Two-Stage Adiabatic Cooling

80-85%
Energy savings
The two-stage adiabatic cooling combines both indirect evaporative cooling and direct adiabatic cooling within a single unit. In the first stage, cold circulating water is produced through evaporation and used to pre-cool the air in an air-water heat exchanger. In the second stage, the air is then further cooled using wet evaporative media.
As no moisture is added to the system in the first stage, the result is significantly cooler and drier air. Therefore, with two-stage adiabatic cooling, even higher efficiency, more optimal hall climate conditions, and reduced water consumption are achieved.

With the two-stage cooling process, the supplied air temperature reaches 19°C under conditions of 35°C and 30% RH (EuroVent), while under warmer, drier conditions (38°C, 20% RH), it can even drop to as low as 17°C.

Why choose adiabatic cooling?

Adiabatic cooling harnesses the power of nature to cool a building, yet it is far more energy-efficient than traditional air conditioners. The two-stage adiabatic IntrCooll for example can achieve an EER value of up to 30-40, which is 10 times higher than that of conventional air conditioners. Furthermore, the performance of traditional systems dramatically declines above 25°C when combined with ventilation, whereas adiabatic cooling continues to improve its performance as temperatures rise, all without increasing energy consumption.

Key advantages of adiabatic cooling

Pristine indoor air quality
Adiabatic cooling utilizes 100% fresh, filtered outdoor air to cool buildings or indoor spaces. With an air exchange rate of up to 6-8 times per hour, the continuous supply of fresh air creates a powerful air-purifying effect, reducing dust, pollutants, carbon dioxide, and carbon monoxide levels while increasing oxygen concentration. This significantly enhances indoor air quality, especially compared to liquid-cooled air handling systems, which often recirculate contaminated indoor air.
Optimal, comfortable temperature
Maintaining a stable temperature is essential for employee comfort, health, and the safe, efficient operation of most manufacturing processes. Two-stage adiabatic cooling ensures a consistent indoor climate, keeping the supply air below 19°C year-round and maintaining indoor temperatures between 25-26°C.
Ideal humidity
Adiabatic cooling technology can achieve up to 60% lower absolute humidity in the supply air, keeping relative humidity within an optimal RH 50-60% range. This helps protect against viruses while ensuring comfort for the throat, nose, eyes, and mucous membranes. Proper humidity control also reduces the risk of material deformation, static buildup, and high dust levels, creating safer conditions for sensitive manufacturing processes.
Carbon-neutral, sustainable operation
The two-stage adiabatic technology is the most environmentally friendly cooling solution on the planet, as it uses water as a refrigerant instead of harmful substances that negatively impact the ozone layer and increase atmospheric CO₂ levels.

Since two-stage evaporative cooling requires minimal power, its carbon emissions are remarkably low. This technology not only meets but exceeds the 2050 targets set by the Paris Agreement, providing an effective solution for companies transitioning to sustainable operations.
Energy efficiency
Two-stage adiabatic cooling utilizes the planet’s most abundant and powerful natural refrigerant, water, to cool the air. The system’s cooling capacity is driven by the natural evaporation process of water, which accounts for 95% of the cooling capacity.

The fan that regulates the process requires only 1 kWh of electrical power to provide 30-40 kWh of cooling capacity and continuous free ventilation.
Cost-effectiveness
The technology enables up to 85% energy savings, minimal water consumption, and low maintenance requirements, all contributing to cost-effective operation, regardless of the configuration in which our solutions are installed.

It is also important to note that by creating a comfortable working environment, employee health and performance are demonstrably improved, leading to reduced costs associated with sick leave and increased productivity.

The efficiency of adiabatic cooling across different climates

Since adiabatic cooling is based on the physical process of water evaporation, different climatic conditions affect the cooling efficiency in varying ways. The hotter and drier the climate, the better the performance of the evaporative cooling system.

Are there any disadvantages to adiabatic cooling?

Does adiabatic cooling increase humidity?
Two-stage (indirect/direct) and direct adiabatic cooling systems affect indoor humidity levels differently, a factor to consider before investment. While direct adiabatic cooling can result in humidity levels as high as 90% RH, our innovative Oxycom-patented two-stage systems reduce absolute moisture content by up to 60%, achieving 10-20% lower relative humidity at the same indoor temperature. In practice, this means that at 27°C, the indoor relative humidity is maximized between 50-60% RH.
Benefits of 40-60% humidity
  • Eliminates the stuffy, tropical feel of air
  • Improves effective (sensibile) temperature, enhancing comfort
  • Reduces airborne dust concentration
  • Reduces the spread of viruses

Heating & Heat Recovery

Our system solutions ensure optimal climate control for your facility throughout all four seasons. Accordingly, during the winter months, they can also be used for heating, utilizing recycled or waste heat as well.

Our solutions offer multilayer customization and integration options, focusing on reducing energy consumption while leveraging renewable or waste energy sources.

Heat Reclaim

The heat generated by equipment, lighting, and personnel naturally rises through convection to the ceiling. With our heat reclaim module, this accumulated warm air is efficiently recirculated into the lower levels of the hall. This ensures a consistent temperature, preheated ventilation air, and a draft-free airflow, optimizing energy use and maintaining comfort.

The modules are available in two configurations: with a hot water heat exchanger or in a direct expansion (DX) refrigerant circulation version.
In specific applications, our proprietary modules enable energy recovery from exhaust air for heating, reducing the load on the heating system and enhancing overall efficiency.

Heat Recovery

If necessary, our two-stage adiabatic systems can be enhanced with heat recovery modules, leveraging recovered energy from exhaust air to preheat incoming cold air.

These solutions are available in multiple configurations, including rotary, cross-flow, or indirect heat exchange modules.

Heat Source

The heaters can be connected to any existing heat source, making them compatible with central boilers, electric, or gas boilers. Additionally, they can be equipped with monoblock heat pumps, capable of fully servicing the system. This flexibility offers high customization in design and installation.

Waste Heat Recycling

In addition to the above, our technologies are also capable of utilizing waste heat. These systems are custom-built and custom-designed, as the available options vary from one facility to another.

Upon request, we identify available waste heat sources within the facility and, using the appropriate technologies and equipment, capture and recycle this energy for heating purposes.

These custom solutions can be combined with our heat reclaim and heat recovery modules, as well as our heat pumps.

Use case for utilizing waste heat

Waste heat source
During operation, the oil inside the air compressor cylinder heads can reach extremely high temperatures, often up to 75°C. This negatively impacts compressor performance and results in a significant amount of wasted thermal energy.
Method of utilization
By utilizing an oil-water heat exchanger and approximately 40°C inlet water, we can cool the oil to 50°C. Concurrently, the inlet water is heated to 70°C, and the released thermal energy is harnessed for heating the facility.

What benefits does it offer?

Energy efficiency
Heat recovery allows for significant energy savings, as it drastically reduces the need for external heating energy. Over time, this results in lower operating costs and a smaller environmental impact.
Flexible plug-and-play design
The heat recovery module can be connected to any heat source (central boiler, electric boiler, gas boiler, etc.), and when integrated with our heat pumps, it provides a fully plug-and-play solution.
Heat-free air exchange
The technology allows for efficient ventilation even during colder periods. By utilizing recovered heat, the reintroduced air can be preheated, minimizing the heating energy demand of the facility. The draft-free airflow also enhances comfort and productivity for employees.
Overheat protection
The automatic control prevents overheating by ensuring that the system only uses the amount of energy required to maintain the optimal temperature in the space.
AI-based control system
Our advanced AI-based control system monitors weather conditions in real time, enabling it to predict energy needs accordingly. For instance, it can store heat generated from solar energy for later use during the winter months.

Ventilation

Optimal air quality and temperature directly impact employee health, the safe operation of manufacturing processes, and ultimately, productivity. Effective ventilation is therefore an essential component of a facility's mechanical systems. Our technologically advanced, sustainable solutions support the creation of comfortable, energy-efficient, and cost-effective working environments.

How is proper ventilation achieved?

Through natural means

Two-stage adiabatic cooling operates on the principle of air displacement cooling. It continuously introduces fresh, cool air into the facility, circulating it throughout the interior, effectively displacing the warm, polluted air that has accumulated inside.
