Dehumidification for Cold Storage

Cooling goods for low-temperature storage can often lead to big problems with unwanted ice, condensation, and in some cases mold – all caused by too much humidity. Humidity is an invisible parameter that can increase operating costs and diminish product quality resulting in poor customer satisfaction.

The control of moisture in freezers and cold storage areas is an operation and safety concern for many businesses.  Spaces like warehouses, refrigerator or freezers that are required to keep the contents of that area extremely cold or frozen have refrigeration systems to control the spaces at their ideal temperature.  When temperatures in these spaces dip below 50°F (10°C) controlling moisture and condensation can be a concern. If not dealt with it can lead to wet and icy spaces, and product that develops frost on it which comprises its quality.  Buildup of frost and ice can also comprise components that are critical for operation of these spaces like the intake to the evaporator coils.

In cold spaces where doors are opening and closing on a regular basis such as cold docks and freezers, the outside air which is let in, is generally warmer.  This warmer air infiltrates into the cold space.  The moisture contained in the warmer air condenses in the form of water or ice in these colder rooms. 

When ice forms it not only builds up on your product/packaging but can built up on components within a freezer from coils and lighting to shelves and pallets. This not only compromises the product but also the facility and could cause equipment to break down or could cause hazardous working conditions for employees.
