💡 Executive Summary

Context: A handicraft enterprise in Hanoi uses the DeAir.RE-600H dryer to ensure the quality of rattan and bamboo products prior to export.
The Challenge: Continuous machine operation requires periodic care to prevent production disruptions and declining drying quality.
The Solution: DeAir provides an official 24-month warranty package and professional preventive maintenance services post-warranty.
The Result: The dryer consistently operates at peak efficiency, equipment lifespan is extended, and the enterprise can focus entirely on production with peace of mind.

1. The Importance of Dryer Maintenance in the Handicraft Industry

1.1. The Sensitivity of Rattan and Bamboo Products

Handicraft products such as rattan, bamboo, lacquerware, and fine wood are highly sensitive to fluctuations in temperature and humidity. An unstable dryer can cause cracking, warping, or mold growth, ruining high-value batches and directly impacting export reputation.

Customer's rattan and bamboo warehouse in Hanoi — Rattan and bamboo warehouses require strict humidity control to maintain export quality.

1.2. Hanoi's Climate and Hidden Costs

Hanoi's climate, characterized by prolonged humid springs and hot summers, forces dryers to operate under high loads. Without periodic maintenance, accumulated dust reduces airflow and accelerates component wear. The hidden cost of waiting for a sudden breakdown (breakdown maintenance) is often exponentially higher than the cost of preventive maintenance.

2. The Golden Commitment from DeAir: 2-Year Warranty & Lifetime Support

At DeAir, we don't just sell machines; we sell peace of mind. Our after-sales policy is clearly divided into two phases:

🛡️ PHASE 1: 24-MONTH OFFICIAL WARRANTY

100% free labor and replacement parts for any manufacturer defects.
Commitment to rapid response and on-site troubleshooting in the shortest possible time.
Leveraging our strategic Branch & Warranty Center in Nhu Quynh, Hung Yen to provide ultra-fast support for Hanoi and neighboring provinces.

🔧 PHASE 2: POST-WARRANTY MAINTENANCE SERVICES

DeAir never abandons its customers. We offer periodic maintenance packages (bi-annually or annually).

Priority access to genuine replacement parts at the best possible rates for existing customers.

3. DeAir's 5-Step Professional Maintenance Process

To ensure the DeAir.RE-600H dryer always operates at peak performance, our technical team strictly follows an ISO 9001:2015 standardized process:

Step 1: Scheduling & Quick Survey

We schedule appointments that align with the enterprise's production calendar to ensure the maintenance process causes zero disruption to workshop operations.

Step 2: Visual & Operational Check

Technicians inspect the evaporator, condenser, and centrifugal fans, while measuring voltage, current, and refrigerant pressure to assess the overall health of the machine.

Step 3: Deep Cleaning & Maintenance

This is the most critical step for restoring performance. Technicians carefully disassemble components for thorough cleaning.

Removing the fan and cleaning the condenser and evaporator coils — Technicians remove the fan and perform deep cleaning on the condenser and evaporator coils to eliminate accumulated dust.

Cleaning the dryer's air filter — Cleaning the air filter ensures optimal airflow and protects the heat exchange coils.

Additionally, we inspect and clear the condensate drainage system, and tighten all electrical connections to ensure absolute safety for the control cabinet.

Step 4: Reassembly & Test Run

After cleaning, all components are precisely reassembled to their original positions.

Reinstalling the fan to its original position — The centrifugal fan is carefully reinstalled to its original position with precise balancing.

The dryer after cleaning, running a test — The fully cleaned dryer undergoes a test run to verify restored performance.

Technicians will recalibrate the temperature and humidity sensors, followed by a test run to ensure the machine achieves its designed capacity of 600 kg/day.

Step 5: Reporting & Consultation

We provide a detailed inspection report outlining the condition of each component. Furthermore, we advise the enterprise owner on operational best practices to save energy and extend the machine's lifespan.

4. Achieved Results
