A-Z Guide to Seafood Cold Storage Design: Optimizing Temperature & Humidity with DeAir

Why is Proper Seafood Cold Storage Design a Matter of Survival?

For Vietnam's seafood industry, conquering demanding export markets like the EU, Japan, and the United States depends not only on the quality of the source but also heavily on the post-harvest preservation process. A properly designed cold storage system is a critical survival factor, determining whether the product retains its freshness, nutritional value, and meets international food safety standards.

Phase 1: Foundational Elements of Cold Storage Design

Before diving into advanced solutions, building a solid foundation for the cold storage is a prerequisite.

1. Determining the Ideal Storage Temperature

Temperature is the first factor to consider. Each type of seafood and preservation state has its own optimal temperature range:

2. Selecting Construction & Insulation Materials

The walls, ceiling, and floor must be constructed with high-density insulated panels (usually PU/PIR) to prevent heat ingress. The floor, in particular, requires thorough waterproofing and insulation to avoid ground frost heave, which can damage the structure.

3. The Cooling System

The cooling system, including the compressor and evaporator coils, must be accurately sized based on the storage volume, product load, and ambient temperature to ensure rapid cooling and stable temperature maintenance.

Phase 2: The "Heart" of Cold Storage - Humidity & Air Quality Control with DeAir

Temperature is only half the story. In a low-temperature environment, air humidity is the root cause of the most serious problems. This is where DeAir's specialized solutions play an irreplaceable role. High humidity not only causes frost but is also the main reason for condensation in cold storage, leading to numerous complications.

The Ultimate Frost Prevention Solution: Dezenno Rotor Dehumidifier

When humid air enters the cold storage and comes into contact with the evaporator coils, the water vapor instantly freezes, forming a thick layer of frost that impedes heat exchange. The optimal solution for this problem is to use a Dezenno Rotor Dehumidifier to treat the air before it enters the storage area.

The Comprehensive Air Quality Solution: AHU Dezenno.MAX

For factories with processing and packaging areas connected to the cold storage, comprehensive air quality control is mandatory to ensure food safety. The AHU Dezenno.MAX system is the all-in-one solution:

• Synchronized Control: Precisely manages both temperature and humidity.
• Air Purification: Integrates G4, F8, and HEPA filters to remove dust and microorganisms, ensuring hygiene.
• Positive Pressurization: Prevents contaminated air and insects from entering from outside.
• Ventilation & Fresh Air Supply: Ensures a clean and safe working environment for employees.

The combination of a rotor dehumidifier and an AHU is the foundation for a comprehensive HVAC solution for seafood factories.
