Humidity and Ice Control for Cold Stores and Freezers

Find your Condair Expert

Benefits

Condair humidifiers and dehumidifiers keep humidity in cold stores and freezers under control. They prevent ice, mist and product drying, improving food quality, safety and energy efficiency.

Prevent ice formation

Dehumidifiers stop ice build-up on floors and doors, improving safety and reducing defrost cycles.

Protect product quality

Stable humidity prevents drying and frost damage, keeping food fresh and within weight specs.

Save energy costs

Less ice means fewer defrost cycles and lower cooling loads, cutting energy use and downtime.

Prevent ice build-up and safety risks

In cold stores and freezers, moisture from open doors, cleaning, and produce quickly condenses and freezes on floors, doors, and sensors. This leads to dangerous icy surfaces, blocked doors, equipment damage, and costly downtime. Condair dehumidifiers remove this excess moisture before it can freeze, keeping storage areas dry, safe, and efficient. With consistent humidity control, ice no longer accumulates on floors or evaporators, meaning fewer defrost cycles, less manual cleaning, and better operational safety. The result is a stable environment that protects both products and personnel, significantly reducing risks and maintenance costs.

Maintain product weight and quality

Cold, dry air extracts moisture from stored goods, causing shrinkage, texture changes and product weight loss. This not only reduces saleable yield but can also compromise the quality and appearance of packaged foods. Condair humidifiers maintain an ideal relative humidity between 60–95% RH, preventing dehydration and preserving the natural weight and structure of food products. By controlling humidity precisely, storage operators can guarantee consistent product quality throughout storage and distribution. This leads to higher customer satisfaction, fewer rejected goods and a clear improvement in profitability and sustainability.

Reduce energy use and defrost cycles

Frost and ice accumulation force refrigeration systems to work harder, consuming more energy and requiring frequent defrosting. Condair dehumidifiers maintain a balanced atmosphere that minimizes frost build-up on cooling coils, floors and walls. This not only reduces defrost frequency but also keeps heat exchangers operating at maximum efficiency. With less ice to remove, cooling systems run more smoothly and require less energy to maintain target temperatures. The result is a measurable reduction in electricity costs, extended equipment lifespan and improved overall energy efficiency — a key factor in sustainable cold-chain management.

Improve visibility and working conditions

Excess humidity inside cold storage rooms causes misting, fog and slippery surfaces that compromise visibility and safety. These conditions slow down workflows, increase accident risks and reduce efficiency. Condair dehumidification systems ensure a clear, dry environment by keeping humidity levels below the condensation threshold. The result is excellent visibility, reduced cleaning needs and improved safety for personnel and machinery. Better visibility also means quicker operations and safer handling of goods - key for maintaining productivity in fast-paced logistics and food processing environments.

Hygienic climate for food-safe storage

High humidity and condensation in cold storage create ideal conditions for bacteria, mould and hygiene problems. Condair systems maintain a constant, optimal humidity that prevents water droplets from forming on ceilings, packaging or surfaces. This eliminates contamination risks and helps facilities comply with food safety regulations such as HACCP. A dry and clean environment ensures that stored goods remain safe, visually appealing and ready for distribution. By combining hygienic operation with energy efficiency, Condair offers the perfect balance between food safety, quality preservation and environmental responsibility.

ICS Cool Energy for a Fish Factory

Condair™s JetSpray humidifier is helping refrigeration equipment specialists ICS Cool Energy increase profits at a leading worldwide brand of canned fish by $1 million per year. By maintaining a high humidity around the fish after steaming, evaporative weight loss from the cooked fish has been reduced from approximately 5% to 0.67%. The humidification system is preventing up to 8.5 tonnes of product from simply evaporating each day between cooking and canning.
