Humidity Control in Refrigerating Chambers and Cold Storage Warehouses
Managing humidity in refrigerating chambers and cold storage warehouses is critical to preserving product quality and reducing energy costs. Uncontrolled humidity can cause condensation, corrosion, mold, and rapid deterioration of goods and building infrastructure.
- How can you prevent product spoilage and surface mold?
- What steps will minimize energy consumption during storage?
- How can you protect packaging, electronic systems, and facility structures?
- What is the ideal storage humidity for different products?
The solution is maintaining optimum humidity using advanced desiccant dehumidifiers. These systems efficiently remove moisture from the air even at low temperatures protecting your assets, equipment, and stored goods.
Problems Caused by Uncontrolled Humidity
- Condensation on walls, ceilings, and cooling coils
- Mildew and bacteria growth on products and surfaces
- Corrosion of metal structures and equipment
- Clumping and sticking of hygroscopic products and packaging
- Failure of electronics and control systems
- Faster deterioration of building infrastructure
- Risk of explosive mixtures (e.g., nitrate-based fertilizer storage)
- Loss of product quality and shelf-life
Vision Air Conditioning’s desiccant dehumidifiers are trusted in the food, chemical, pharmaceutical, agricultural, and consumer goods industries across Canada and the USA.
Benefits of Desiccant Dehumidification in Cold Storage
- High drying efficiency with low energy consumption
- Reliable operation even at subzero temperatures
- Simple installation and compact design
- Fully automated humidity control
- Corrosion-resistant (stainless steel or aluminum-zinc construction)
- Meets strict EU and North American safety standards
Key Storage Humidity Levels
- Meat, chilled meat, by-products: 75–90% RH
- Cheese (long storage): 75–80% RH
- Butter, cottage cheese: 60–80% RH
- Milk, condensed milk: 70–80% RH
- Dry milk products: up to 75% RH
- Natural herbs, spices: 70–75% RH
- Medicines (capsules, syrups): 30–45% RH
- Auxiliary packaging, string: 14–70% RH
- Prevents mold and mildew growth
- Protects against condensation and corrosion
- Maintains packaging quality and integrity
- Extends shelf life for food, pharma, and consumer goods
- Ideal for food industry and pharma cold rooms
How Desiccant Dehumidifiers Work
Process air is passed through a silica gel rotor, which adsorbs water molecules from the air. A separate preheated air stream (90–140°C) regenerates the rotor, removing moisture as warm, humid exhaust keeping storage spaces dry and safe in all seasons.
