Preventing Caking & Preserving Fertilizer Quality: DeAir's Solutions for Manufacturers and Distributors

"Capital" Turning to Stone: The Silent Worry of Vietnam's Fertilizer Industry
Fertilizer is the working 'capital' for businesses and the 'capital' for farmers' crops. But in Vietnam's humid climate, that 'capital' can literally turn to stone. Most inorganic fertilizers are hygroscopic, meaning they absorb water vapor from the air. When humidity exceeds a critical threshold, the surface of the fertilizer granules dissolves and fuses together upon drying, forming hard lumps and causing a series of serious damages.
The Harms of Humidity on Fertilizer
🪨
Caking
Makes it difficult to use and bag the product, reducing its commercial value.
📉
Quality Degradation
Moisture causes loss of nutritional content (N, P, K) and product deterioration.
📦
Packaging Damage
Paper or PP bags become damp, weak, and tear easily during transport and storage.
💸
Economic Loss
Direct losses from damaged goods, increased labor costs for handling, and damage to brand reputation.
The "Golden" Humidity Standard for Fertilizer Warehouses
Based on research and practical experience, maintaining the warehouse air humidity below the 40% RH threshold is a critical factor in completely preventing caking. More specifically, the bagging area requires an even stricter level of 35% RH to ensure dry air is sealed into the packaging. Humidity control not only protects the product but is also a key part of maintaining Good Storage Practices (GSP) and complying with state regulations such as Vietnam's Decree 84/2019/NĐ-CP on fertilizer management.
DeAir's Comprehensive "Tailor-Made" Solutions as a Direct Manufacturer
As a direct manufacturer in Vietnam, DeAir has a distinct advantage in providing "tailor-made" solutions for its customers. We can fully customize machine components such as shell materials, fan capacity, and compressor types to meet the specific requirements of each project. For the fertilizer industry, DeAir proposes the following tiers of solutions:
1. The Durable & Corrosion-Resistant Solution (Top Priority)
Due to the highly corrosive nature of chemical vapors from fertilizers, the top-priority solution is to use dehumidifier models with an optional INOX 304 stainless steel shell. This shell offers far superior resistance to oxidation and chemical corrosion, ensuring long-term durability and stability. This stainless steel option is available for both floor-standing models like the DeAir.RE-H and the DeAir.RE-CL ceiling-mounted dehumidifier, providing maximum flexibility for warehouse design.
The DeAir.RE-H with a stainless steel shell is designed to withstand corrosive environments.
2. The High-Performance & Precision Solution
For warehouses in colder regions (e.g., Northern Vietnam in winter) or for special fertilizers requiring ultra-low humidity (below 40% RH), the Dezenno rotor dehumidifier is the mandatory solution. Rotor technology is unaffected by temperature, operates extremely efficiently at low humidity, and is inherently corrosion-resistant from the inside, as the rotor wheel is made of chemically inert silica gel material.

Which Solutions Do Leading Fertilizer Companies in Vietnam Choose?
Vietnam's fertilizer market is vibrant, with many large enterprises of varying scales and production technologies. Investing in a professional preservation system is one of the key factors that create a competitive edge.
State-Owned and Equitized Corporations: Giants like Vinachem (with members such as Lam Thao Fertilizers and Chemicals, Ha Bac Nitrogenous Fertilizer) and companies under PetroVietnam (such as Phu My Fertilizer, Ca Mau Fertilizer) often possess massive warehouse systems that require high-capacity, durable industrial dehumidifiers with the ability to integrate into central management systems.
Private and Joint-Venture Enterprises: Companies like Binh Dien Fertilizer, Southern Fertilizer, and Vinafer... place a strong emphasis on product quality and stability. They often seek "tailor-made" solutions, which could be dehumidifiers with stainless steel shells for storing special products or rotor dehumidifiers for high-grade NPK production lines.
Choosing the right humidity control solution helps these businesses not only protect their goods but also affirm their position and brand quality in the market.
