Benefits

The use of evaporative cooling with adiabatic air humidification improves the indoor climate and productivity.

Higher productivity

Reduced heat loads with adiabatic cooling ensure optimal process parameters.

Healthier indoor climate

Adiabatic cooling protects health and reduces employee complaints.

Lower energy costs

Reduced costs for air conditioning and low energy consumption.

Increased productivity through evaporative cooling

A controlled indoor climate is a decisive factor for productivity and quality in industrial manufacturing processes, in offices and even in data centres. Excessively high temperatures and low humidity have been shown to reduce work performance and increase the likelihood of errors and accidents. Studies show that productivity can drop by 3 to 12% in conditions of high heat stress. In addition to employee performance, the indoor climate also influences the quality of the end products, as many materials and manufacturing steps are sensitive to temperature fluctuations. Adiabatic evaporative cooling offers an efficient solution for lowering room temperature and stabilising humidity. This standardises production processes, ensures quality and sustainably increases productivity.

Evaporative cooling for healthy indoor climate

The health and safety of employees is a key concern for modern industrial companies. Excessively high temperatures in the workplace can lead to health problems such as headaches, exhaustion, dehydration and, in extreme cases, heat stroke. At the same time, excessively low humidity promotes respiratory infections, mucous membrane irritation and increased virus transmission. Adiabatic evaporative cooling with additional air humidification ensures a pleasant and healthy indoor climate. Optimal humidity protects the respiratory tract, reduces dust and minimises electrostatic charges. Companies benefit from fewer absences due to illness and higher employee satisfaction. This technology effectively supports compliance with legal requirements for occupational safety.

Cut energy costs with evaporative cooling

Adiabatic evaporative cooling is one of the most energy-efficient methods for cooling production and work spaces or even data centres. Compared to conventional air conditioning units, it can reduce cooling energy costs significantly. The principle uses the evaporation of water to extract heat from the ambient air, which can lower the temperature by an average of 2 to 5 °C – with minimal energy consumption. High-pressure nozzle humidifiers installed directly in the room, for example, require only 0.6 kW of energy to evaporate 100 litres of water and absorb around 70 kW of heat. This technology enables a sustainable reduction in energy consumption and contributes significantly to lowering operating costs.

Start of air humidification

The direct room humidifier is installed on the hall ceiling.

Start of adiabatic cooling

Complete absorption of the sprayed water droplets begins.

Result of cooling

Reduction in room temperature by 4 °C.

Argelith Bodenkeramik H. Bitter GmbH, Bad Essen (Germany)

Argelith Bodenkeramik H. Bitter GmbH (Bad Essen) is one of the world's leading companies as a manufacturer of high-quality industrial tiles. In order to reduce the high heat loads caused by the thermal processes of production, the company uses direct room air humidification.

V-ZUG, Switzerland

As a manufacturing company for household appliances for kitchens and laundry rooms, V-ZUG has a dual impact on the environment: they design appliances to be as efficient in use as possible, and they produce these appliances with maximum resource efficiency and minimal emissions.

The new Zephyr Hangarœ building at the Zug site houses a new sawtooth-roof structure that includes the pressing facility, where manufactured parts are also enameled. These production processes generate large amounts of waste heat, resulting in extremely dry indoor air, which in winter can drop to just 10 percent relative humidity. This presents a major challenge for the comfort of employees and the wood-intensive building, as the wooden structure requires a minimum humidity level of 30 percent relative humidity. Additionally, this situation poses a significant challenge for sustainable cooling.

This is where Condair comes into play! The solution involves Condair˜s high-pressure nozzle system,
ML-FLEX, with 152 nozzles providing a nethumidification capacity of approximately 280 liters per hour and a simultaneous, calculated evaporative cooling effect of 16 Kelvin, meaning the room air is sustainably cooled from around 38 degree centigrade to approximately 22 degree centigrade during the humidification process.

Facebook / Meta, Sweden

This data centre in Lulea Sweden is one of the world™s most efficient and sustainable data centres. It is powered with locally generated hydro-electric energy and uses the cold Nordic air to cool the servers that store Facebook users˜ photos, videos, comments and likes.

Condair evaporative humidifiers add up to 22,800 litres per hour to the air in the penthouse ventilation systems to maintain the humidity to ASHRAE standards across the data halls.
