[Case Study] DeAir Hands Over Daxwell Drying Room for Paper Rolls in Quang Ngai

Context: The Challenge of Drying Paper Rolls in a Coastal Climate

The paper manufacturing industry in Vietnam, especially in coastal regions like Quang Ngai, constantly faces a major challenge from the climate. With hot, oppressive weather and significant rainfall throughout the year, the air's humidity is consistently high, directly impacting the production process. Drying industrial paper rolls requires a solution that is not only fast and uniform but also ensures the paper quality is not compromised by warping, wrinkling, or moisture reabsorption.

Confronted with this problem, on October 15, 2025, DeAir successfully completed the installation, handover, and commissioning of a modern Daxwell drying room system for a key partner in Quang Ngai, providing a breakthrough solution to overcome the difficulties of traditional drying methods.

1. The Customer's Challenge: Overcoming the Limitations of Traditional Drying

Previously, the business faced numerous difficulties with conventional drying methods:

• Natural Sun Drying: Completely dependent on the weather, requires large spaces, takes many days, and is unhygienic, easily allowing dust to settle on the paper.
• Electric Resistance Ovens: Consumes an enormous amount of electricity, making operating costs very high, and it is difficult to control the temperature precisely, leading to the risk of over-drying and making the paper brittle.

The requirement was for a proactive, effective drying solution that could significantly shorten the drying time while ensuring uniform paper quality from the core to the outer layers, all with reasonable operating costs.

2. The Comprehensive Solution from DeAir: The Daxwell Heat-Pump Drying Room

DeAir provided a total solution, not just a dryer, but a complete drying room system "tailor-made" to the customer's needs, including:

• The Daxwell Heat-Pump Dryer: The "heart" of the system, providing a recirculating flow of dry, hot air at a low energy cost, with operating expenses being only half that of resistance heating solutions.
• Panel Drying Room: Constructed from high-quality PU insulated panels to ensure excellent heat retention and prevent moisture infiltration from the outside, maximizing drying efficiency.
• Smart PLC & HMI Control System: Allows the client to easily set and customize drying cycles (temperature, humidity, time) with precision via a touchscreen, ensuring consistent quality for every batch.
