Dehumidifier for Paper Production: A Comprehensive Solution from DeAir

Humidity – The Silent Enemy of the Paper Industry & International Standards

Vietnam's paper industry is on a strong growth trajectory, accompanied by increasingly stringent demands for product quality. However, there is a "silent enemy" that can ruin an entire batch in a short time: Air humidity.

A Real-World Example of Humidity's Impact

In countries with tropical humid climates, many cardboard packaging manufacturers have recorded product defect and warping rates of up to 15-20% during the rainy season. The main cause is identified as the paper sheets (raw material) absorbing moisture from the environment, which reduces stiffness and causes deformation during the stamping process. This situation not only causes direct financial losses but also affects delivery schedules and the company's reputation. (Source: TAPPI Technical Journal)

What Do Industry Standards Say?

To ensure consistency and product quality, international organizations have established very clear standards. According to the Technical Association of the Pulp and Paper Industry (TAPPI), the international standard for testing and storing paper (TAPPI T402) requires the environment to be maintained at a relative humidity (RH) of 50% ± 2% and a temperature of 23°C ± 1°C. Maintaining stable humidity within this range ensures that the mechanical properties of paper, such as tensile strength, tear resistance, and stiffness, are guaranteed.

Any deviation can lead to serious problems at every stage:

• Raw Material Storage: Pulp and waste paper become lumpy, moldy, and the fiber quality degrades.
• During Production: Paper becomes soft, prone to tearing during sheeting, changes dimensions, warps upon cooling, and causes ink bleeding during printing.
• Finished Product Storage: Paper easily absorbs moisture, causing sheets to stick together, deform, turn yellow, and creating conditions for mold growth, leading to significant economic losses.

Why is DeAir the Top Choice for Achieving Humidity Standards in the Paper Industry?

To thoroughly address the above issues and help factories in Vietnam meet international standards, DeAir offers specialized and comprehensive humidity control solutions.

• Deep Technical Expertise: The DeAir engineering team has extensive experience working with leading brands like Bry-Air and Munters, possessing a deep understanding of the technical requirements for various types of paper.
• Energy-Saving Heat Pump Technology: DeAir dehumidifiers use heat pump technology to reuse heat energy to warm the air after moisture removal, significantly saving operational costs – a critical factor for factories operating 24/7.
• Advanced Dehumidification Solutions: DeAir also provides rotor dehumidifiers (Dezenno), capable of controlling humidity to very low and precise levels (below 40% RH), suitable for specialty papers or storage facilities with strict requirements.
• ISO 9001:2015 Certified After-Sales Service: DeAir is committed to partnering with customers from installation and operation to regular maintenance, ensuring the system operates stably and efficiently.

Specialized DeAir Dehumidifier Models for Paper Mills

Based on the specific needs of each area, DeAir proposes the following optimal solutions:

1. Production and Drying Areas (High Temperature): Heat-Pump Dryer DeAir.RE-H

This series is designed to operate efficiently in high-temperature environments (up to 60°C), suitable for the paper drying stage or areas near heat-emitting machinery.

Recommended Models: DeAir.RE-600H, DeAir.RE-900H, DeAir.RE-1200H

2. Finished Product Storage (Very Low & Precise Humidity): Rotor Dehumidifier Dezenno

Adsorption rotor technology helps control humidity at very low and precise levels, completely preventing the paper from re-absorbing moisture and preserving its original quality and shape.

Recommended Models: The Dezenno 320-1200 CMH series and the Dezenno 1500-18000 CMH series, depending on the warehouse volume.

3. Large Workshops, Finishing Areas: Large Capacity Dehumidifier DeAir.RE (3-phase)

This is a cost-effective solution for controlling humidity over large areas, using energy-saving heat-pump technology to ensure a consistently dry and stable working environment.

Recommended Models: DeAir.RE-900, DeAir.RE-1200

4. Space-Saving Ceiling Solution: Ceiling Mounted Dehumidifier DeAir.RE-CL

Specially designed for fixed ceiling installation, freeing up valuable floor space, making it ideal for factories that need to optimize their layout.

Recommended Models: DeAir.RE-300CL, DeAir.RE-600CL
