• 7. Frequently Asked Questions (FAQ)

• Context: An electronic components factory in Binh Duong required a cleanroom for finished goods storage with a specific technical requirement: maintaining high temperature but ultra-low humidity.
• Challenge: Traditional condensation (heat-pump) dehumidifiers cannot achieve low dew points in high-temperature environments.
• Solution: Installation of a Dezenno rotor dehumidifier system (European standard), specifically designed for ultra-low humidity applications.
• Result: The system operates stably, passed rigorous testing by an independent 3rd-party verification agency, ensuring absolute safety for high-value electronic components.

⚠️ TECHNICAL LIMITATIONS

• Standard heat-pump dehumidifiers: Will experience evaporator coil freezing or lose efficiency entirely when attempting to lower humidity to extreme levels in high-temperature environments.
• Dew point constraints: Cannot achieve dew points < 10°C with traditional condensation technology.
• Performance drop: Ineffective operation when humidity requirements drop below 30% RH.

🔧 SUPERIOR ADVANTAGES

• Desiccant Technology: Utilizes a silica gel rotor wheel, capable of effective dehumidification even at very low dew points, regardless of ambient temperature.
• European Standards: Manufactured to European standards, researched and applied by DeAir for over 20 years in Vietnam.
• Ultra-low humidity: Capable of achieving < 10% RH or dew points < -40°C.
• Stable operation: Unaffected by the high temperatures of the cleanroom.

✅ VERIFICATION ITEMS

1. Temperature and humidity uniformity: Grid testing at multiple points in the room to ensure no localized "dead spots" of humidity.
2. Recovery time: The time required for the system to restore target humidity after the room door is opened.
3. Air cleanliness (Particle count): Ensuring the Dezenno system's filters do not generate particles, meeting the required cleanroom class.
4. Noise and vibration: Ensuring no interference with surrounding precision measurement equipment.

• Stable humidity: Maintained at < 20% RH at high temperatures (25-30°C).
• High precision: ±1-2% RH accuracy thanks to the PLC control system and VFD.
• Uniformity: No localized "dead spots" of humidity throughout the cleanroom.
• Recovery capability: Humidity recovery time after door opening is < 15 minutes.

📊 CLEANROOM STANDARDS FOR ELECTRONIC COMPONENTS STORAGE

Q1: Why does an electronic components storage cleanroom require both high temperature and low humidity simultaneously?

High temperature (25-30°C) helps prevent condensation when components are moved to ambient environments. Ultra-low humidity (< 20% RH) prevents lead oxidation and the "popcorn" effect (IC cracking due to absorbed moisture). This is a mandatory requirement under the IPC/JEDEC J-STD-033 standard for Moisture Sensitive Devices (MSD).

Q2: How does a Dezenno rotor dehumidifier differ from a standard heat-pump dehumidifier?

The Dezenno rotor dehumidifier uses desiccant technology with a silica gel wheel, capable of achieving ultra-low humidity (< 10% RH) and very low dew points (< -40°C) even at high temperatures. In contrast, heat-pump dehumidifiers are only effective at humidity levels > 30% RH and will lose efficiency or freeze at low temperatures/ultra-low humidity.

Q3: What benefits does 3rd-party verification bring to the investor?

Independent 3rd-party verification (e.g., Quatest, VILAS) provides: (1) Objectivity and transparency, (2) Assurance that the system meets IPC/JEDEC and Cleanroom standards, (3) A legal verification report proving compliance, (4) Absolute confidence in system quality before official operation.

Q4: Is the maintenance cost for the Dezenno rotor wheel high and complex?

The maintenance cost for a Dezenno rotor is very reasonable. The rotor wheel has a lifespan of 5-10 years depending on operating conditions. DeAir provides scheduled maintenance every 6 months, including filter cleaning, regeneration heater checks, and sensor calibration. With a nationwide technician network and readily available spare parts, DeAir ensures rapid and effective support.
