Desiccant dehumidifiers conserve energy, improve safety, and contribute to a cleaner atmosphere. Moisture control in freezers and loading docks is a major operational challenge in a large number of institutions. Cold storage warehouses, product coolers, and cold docks are often equipped with massive central refrigeration systems that keep the freezers and docks operating at the proper temperature. At temperatures below 50 degrees Fahrenheit, a refrigeration system alone is impractical for moisture and condensation control. As a result, damp or ice floors, frosted evaporator coils, fog, and frosted product may result.
The primary source of moisture in active/dynamic freezers and docks is door openings caused by products being moved into and out of the freezers, coolers, and docks. This activity allows for the infiltration of outside ambient air, which is often significantly more wet, into the docks and freezers. In rooms above freezing, the moisture in the air condenses as liquid, while in subfreezing environments, it condenses as ice.
Condensation develops on all surfaces, posing a hazard to pedestrians due to slick floors and ice buildup on racks, coils, and lighting fixtures. When frozen products are transported through areas with greater relative humidity, frost can form on the outside of the pallets, obscuring bar codes and interfering with automated handling equipment.
Automatic doors, door seals, and strip curtains all help to decrease but not eliminate this invasion. The number of doors and the volume of traffic are crucial variables in calculating the moisture load accurately.
A desiccant dehumidification system is a successful long-term solution for removing moisture from infiltration, reducing or eliminating frost on evaporator coils, and preventing wet floors and ice formation on walls, floors, refrigeration components, and conveying systems.
Cardboard containers' moisture absorption is likewise regulated, ensuring their strength and stability.
This increases the overall safety of the operation and results in a more energy-efficient system.
Preventing condensation and ice and frost build-up on walls, floors, coils, and ceilings requires removing moisture from ambient air before it enters the freezer/dock. A desiccant dehumidification system supplies cool, dry air and enables the freezer/dock to function under positive air pressure, preventing moisture from entering the compartment. The dehumidifier is sized according to the size and structure of the freezer and docks, the number and kind of dock and freezer doors, and the anticipated traffic through the freezer and dock.
