Cold Room Humidity Control
Reduce shrinkage. Extend shelf life. Protect your profits.
High-Pressure Humidification for Cold Storage
Maintaining the correct humidity inside cold rooms is crucial for preserving product quality and preventing unnecessary weight loss. Refrigeration systems naturally strip moisture from the air, causing produce, meat, and perishable goods to dehydrate at a rapid rate. Misting SA's high-pressure humidification systems stabilise relative humidity, protect your inventory, and ensure the cold chain operates at maximum efficiency.
Why humidity matters in cold rooms
Low humidity leads directly to product dehydration. Even a small drop in natural moisture results in measurable financial loss. Maintaining stable humidity reduces dehydration and protects the texture, weight, and freshness of stored goods.
Problems caused by low humidity
- Weight loss of up to 20% depending on product type
- Loss of firmness, crispness, and colour
- Shortened shelf life
- Increased product waste
- Higher rejection rates from retailers
- Packaging materials becoming brittle and splitting
- Reduced visual appeal and market value
Benefits of high-pressure humidification
Reduce weight loss (shrinkage)
Stabilised humidity prevents rapid moisture loss, protecting saleable mass.
Extend shelf life
Ideal humidity slows respiration and cellular breakdown of fresh produce.
Maintain freshness
Fruits, vegetables, meat, and flowers retain their natural colour, structure, and moisture.
Improve profitability
Reduced shrinkage = higher sellable weight and lower waste.
Protect packaging & textures
Proper humidity prevents boxes, trays, and films from drying and cracking.
How the system works
Our system uses ultra-fine high-pressure fog (5–10 micron droplets) that evaporates instantly inside the cold environment without wetting products or surfaces.
- High-pressure pump atomises water into ultra-fine droplets
- Fog evaporates into the cold air, increasing RH instantly
- No condensation forms — ideal for food safety
- Sensors monitor RH and temperature continuously
- Automated controls maintain stable humidity 24/7
Ideal applications
- Fruit cold stores (apples, pears, citrus, berries, grapes)
- Vegetable storage rooms
- Meat & carcass coolers
- Fish & seafood cold rooms
- Floriculture storage
- Cheese maturation rooms
- Supermarket back-rooms
- Distribution centres
Automation & monitoring
Automatic start / stop
Triggered when humidity drops below setpoint, when door openings cause rapid air exchange, or when temperature fluctuations influence RH.
Multi-zone control
Each cold room or chamber can be controlled independently.
Compatible with
- Most commercial cold-store controllers
- PLC-based systems
- Standalone RH/Temperature controllers
