Dehumidifiers for Manufacturing Plants | Optimal Humidity Control Solutions from DeAir

Dehumidifiers for Manufacturing Plants - DeAir Analyzes the Most Suitable Choice

High humidity is a significant challenge in the industrial environment in Vietnam, especially in hot and humid climates such as the South or during long periods of damp weather in the North. Ineffectively controlled humidity can become a "silent enemy," causing serious consequences that affect product quality, production efficiency, equipment durability, and even worker health. Finding a reliable and suitable humidity control solution is extremely necessary for businesses.

In this context, industrial dehumidifiers become indispensable equipment for maintaining an ideal working environment and preserving goods in manufacturing factories and warehouses.

Why is humidity control important for manufacturing plants?

Humidity exceeding the allowable threshold causes many negative effects:

• Affects product quality: Goods such as paper, fabric, dry food, pharmaceuticals, and electronic components are susceptible to mold, deterioration, or oxidation when humidity is high. Fertilizers can clump. Fabrics and fibers can become moldy, affecting color fastness.
• Reduces lifespan and causes damage to machinery and equipment: Machinery left in a humid environment for a long time is susceptible to corrosion and rust, especially metal parts or electronic microcircuits. High humidity can cause electrical short circuits, reducing processing accuracy.
• Disrupts the production process: Damaged goods or machinery stopped working due to humidity can interrupt the entire production line.
• Impacts workers' health: Humid environments create conditions for bacteria and mold to grow, affecting the respiratory system and general health.

Popular types of industrial dehumidifiers

Currently on the market, there are two main technologies for industrial dehumidifiers:

1. Refrigerant Dehumidifier: Works based on the principle of refrigeration to condense water vapor in the air.
   • Advantages: Popular, initial investment costs are often lower. Works effectively at normal room temperature and high relative humidity.
   • Disadvantages: Performance drops significantly when temperature or humidity drops; may need to stop for defrosting when operating at low temperatures.
2. Rotor Dehumidifier: Uses desiccant material (such as silica gel, zeolite) on the rotor to adsorb water vapor from the air. This material is then regenerated by hot air flow to remove moisture.
   • Advantages: Excellent efficiency at low temperatures and ability to achieve very low humidity (down to 10% RH). Continuous operation without interruption. More durable in harsh environments.
   • Disadvantages: Initial investment costs and operating costs (especially heating energy for the regeneration process) are often higher.

In addition, the AHU (Air Handling Unit) Air Handling System is also a comprehensive solution, integrating many functions such as air filtration, temperature control, and dehumidification or humidification, suitable for large spaces that require tight environmental control.

Humidity control solutions for manufacturing plants from DeAir

DeAir Joint Stock Company is a reputable unit in Vietnam specializing in manufacturing and supplying HVAC equipment, including industrial dehumidifiers and AHU air handling systems. With experience and production capacity in Vietnam, DeAir provides solutions suitable for climate conditions and specific needs of the domestic market.

Here is how to apply the DeAir dehumidifiers to each type of popular production workshop:

1. Mechanical Manufacturing Workshop (Processing, assembling)

• Challenges: Machinery and metal products are susceptible to rust and corrosion due to high humidity, affecting processing accuracy.
• Humidity requirements: Usually maintained below 60-65% RH to prevent rust.
• DeAir solution:
  • DeAir RE series dehumidifiers (condensing type): Models such as RE-60, RE-150, RE-300, RE-600, RE-1200 are economical and effective choices for maintaining this target humidity, especially with Heat-Pump energy-saving technology. The machine capacity is selected based on the area and actual humidity load of each workshop.
  • DeAir RE-H series dehumidifiers: If the workshop has a slightly low temperature or needs light drying support after cleaning, models with an additional output heater can be useful.

2. Food and Confectionery Manufacturing and Packaging Plant

• Challenges: Raw materials and products are susceptible to mold and deterioration. The packaging process requires a dry product surface for effective labeling. Hygiene requirements are very high.
• Humidity requirements: Maintain below 50-60% RH at many stages. The packaging area may require lower humidity to ensure good labeling and prevent moisture infiltration.
• DeAir solution:
  • DeAir RE series dehumidifiers (condensing type): Suitable for general production and storage areas, with energy saving capabilities thanks to Heat-Pump technology.
  • DeAir RE-H series dehumidifiers: For packaging areas that require a quick drying surface, the RE-H models feature a heating function that supports this gentle drying process.
  • DeAir Dehumidifier model Stainless Steel Shell: This is the ideal solution for food factory environments due to hygiene requirements and corrosion resistance. According to the actual requirements of specific industries, these Stainless Steel Shell models have the same dehumidification capacity as the DeAir RE-H series models, but are made of durable, easier-to-clean stainless steel, suitable for environments that are likely to generate moisture or mild cleaning chemicals.
  • Dezenno.MAX AHU System: For large factories that require comprehensive environmental control of temperature, humidity, and cleanliness (can integrate HEPA filters).

3. Textile and Garment Factory (Fiber Warehouse, Finished Fabric Warehouse)

• Challenges: Fibers and fabrics easily absorb moisture, causing mold, affecting quality and color fastness. Unstable humidity affects the spinning and weaving process.
• Humidity requirements: Maintain relatively stable humidity, usually between 55-70% RH depending on the type of material and process. Finished goods warehouses need lower humidity to prevent mold.
• DeAir solution:
  • DeAir RE series dehumidifiers (condensing type): Suitable capacity models (RE-300, RE-600, RE-1200) are an effective solution to control humidity in this range for both production and storage areas, while saving energy with Heat-Pump technology.
