Benefits
Managing humidity to prevent evaporation has many benefits
Improved Yields
Products retain their mass providing greater sales value when sold by weight.
Enhanced Quality
Materials that retain their original moisture content maintain integrity and quality.
Improved Profits
Less waste, better quality and increased yield all result in more profits.
Using Humidity to Prevent Evaporative Losses
Understand the Problem
Condensation occurs when warm, humid air comes into contact with a cooler surface, causing the moisture in the air to condense into water. This accumulated moisture can encourage mould growth, corrosion, and the deterioration of stored materials.
The main factors to manage are relative humidity, temperature variation, and ventilation. Mold begins to grow rapidly when relative humidity rises above 60 per cent. Significant temperature differences can cause cold surfaces to attract condensation. Poor ventilation and limited air movement also create stagnant conditions that increase the likelihood of localized condensation.

Prevent Condensation and Mold
Preventing condensation and mold requires controlling moisture, temperature, and airflow. The strategies vary slightly depending on whether you are dealing with residential/archival spaces or industrial environments, but the principles are similar.
Example: To maintain a basement/cellar condensation and mold free, we use a Condair DA adsorption-dryer combined with an effective ventilation system.

General Strategies to Avoid Condensation and Mold - Control Humidity and Temperature
To control humidity, dehumidifiers are often the most effective solution. In basements or archival spaces, dehumidifiers can be used to keep relative humidity below 50 to 55 per cent. Larger environments may require large-scale desiccant or refrigeration-based dehumidification to maintain consistently low humidity levels. Moisture barriers also play an important role. Walls and floors can be sealed with vapor barriers such as polyethylene sheeting or epoxy coatings, while archival collections benefit from moisture-resistant storage materials including acid-free boxes and protective plastic enclosures. Managing moisture at its source is equally essential. Leaks in roofs, walls, or pipework should be repaired promptly, and buildings must have adequate drainage to prevent water accumulating around the structure.
Controlling temperature is another key measure. Insulating cold surfaces helps to prevent condensation from forming, which is particularly relevant for basement walls and floors or cold storage surfaces used in food processing facilities. Maintaining stable temperatures reduces the risk of rapid changes that encourage condensation. In archival environments, room temperatures should be kept slightly above the dew point of the air to minimize the potential for moisture to form on surfaces.

General Strategies to avoid condensation and mold - Airflow and Ventilation
To reduce the risk of condensation and mold, it is also important to maintain a good airflow and ventilation. Improving air circulation helps to eliminate stagnant pockets of air where moisture is more likely to accumulate. Fans can be used in basements and archival rooms to keep air moving, while industrial facilities should ensure that ventilation is directed towards areas where cold surfaces are present. It is also essential to remove humid air at its source. Kitchens, production lines, and storage areas should be equipped with suitable extraction systems to expel moisture-laden air before it has the chance to condense on nearby surfaces.
Preventing Evaporative Loss is Beneficial in Many Industries

Parmeshwari Tea, India
Humidity control specialist, Condair, and its Indian distributor, Regent Machine & Servicing, has supplied and installed a JetSpray humidification system at Parmeshwari Tea factory in Assam. The compressed air and water spray humidifier is maintaining the ideal humidity in the CTC and CFM areas to prevent moisture loss from the tea during processing and fermentation. This results in a consistently high-quality tea, which is blacker and with stronger liquor, no matter what the ambient weather conditions are like.
Biltong drying success with Condair & JTR
Specialist South African food supplier, The Savanna, is using Condair dehumidifiers to dry its award winning biltong at its production facility in London. Two Condair dehumidifiers were installed by John Todd Refrigeration (JTR) to help in the production of this traditional South African product.
Biltong is a dried and cured meat, with a rich and dense flavour, which is cut into strips and often eaten as a snack. The Savanna’s biltong is produced using grass-fed beef from the Scottish highlands and a traditional South African curing method. Silverside beef slabs are sliced into strips and then marinated before being mounted on hooks for air drying, which is where Condair’s dehumidifiers assist in the process.
