Complete humidity balance for every crop

Healthy plant growth depends on humidity that is neither too high nor too low. Condair systems automatically balance both — adding moisture when air is dry and removing it when condensation risks appear. This equilibrium supports photosynthesis, nutrient uptake, and transpiration. Whether growing flowers, vegetables or ornamentals, a stable humidity ensures faster rooting, uniform growth, and stronger plants with fewer losses. The result is a predictable, high-quality harvest throughout all seasons.

Create uniform growing conditions

Humidity differences between greenhouse zones often cause uneven plant development. Condair systems distribute humidity evenly through precise sensors and airflow management. The result: identical growth rates, consistent flowering, and even coloration across the entire crop area. Balanced air moisture also stabilizes temperature, improving efficiency for heating and cooling systems. Growers benefit from reliable yield forecasting and reduced crop losses — ideal for both small horticultural setups and large-scale operations.

Improve crop yield and quality

Too much humidity leads to condensation, creating the perfect environment for fungal diseases such as Botrytis, rust and powdery mildew. Condair dehumidifiers maintain humidity below the dew point, keeping leaves dry and surfaces clean. By combining gentle air circulation with energy-efficient moisture removal, Condair prevents mould and leaf damage while reducing pesticide use. A stable, dry climate means healthier crops, longer shelf life, and improved profitability

Protect plants from drying and stress

When greenhouse air becomes too dry, plants lose moisture rapidly through transpiration. This causes wilting, leaf burn and slower growth. Condair humidity control restores the right level of air moisture, ensuring plants remain hydrated and photosynthesis stays efficient. Balanced humidity keeps stomata open for CO₂ intake, improves nutrient absorption and enhances overall vitality. As a result, crops grow faster, recover better after pruning, and achieve higher yield quality with less energy and water loss.

Save energy with intelligent climate control

Traditional methods such as window ventilation or dry heating waste large amounts of energy. Condair systems maintain ideal humidity without excessive heating or cooling, saving up to 55% in energy use. Advanced control technology ensures dehumidifiers and humidifiers work together efficiently — adding or removing moisture only when necessary. Integrated heat recovery and low-maintenance design make Condair the most sustainable solution for modern greenhouse climate control

Sustainable and water-efficient technology

Condair systems not only optimise humidity — they also promote resource efficiency. By minimising the need for heating, dehumidification lowers greenhouse gas emissions and operational costs. Meanwhile, adiabatic humidifiers provide natural evaporative cooling, lowering ambient temperatures and energy costs. This closed-loop approach supports eco-friendly horticulture — combining crop productivity with resource efficiency. With robust design and minimal maintenance needs, Condair systems deliver long-term performance for a greener future in controlled environment agriculture.

Use cases

Condair humidity control in greenhouses prevent mould, save energy, ensure uniform growth and protect horticulture crops from diseases.

Prevent evaporative losses

Organic materials have an internal moisture content and will lose moisture to the atmosphere when exposed to air with a low humidity. Humidifiers are used to create an environment with perfect balance between the material’s internal moisture content and the air’s relative humidity.
