The Limits of "Dry Cabinets" & The Comprehensive Cleanroom Humidity Control Solution for R&D

When the "Glass Cabinet" Becomes Too Small for R&D Ambitions

In the initial startup phase, laboratories often equip themselves with small Dry Cabinets to preserve specimens. However, as research scales up into sensitive fields such as Pharmaceuticals, Lithium Batteries, Semiconductors, or Biotechnology, dry cabinets reveal serious technical limitations that directly threaten the accuracy of research results.

Instead of confining space within a cabinet, the advanced solution today is "Room-Scale Humidity Control" - Transforming the entire laboratory into an internationally standard clean and dry space.

1. Why Dry Cabinets Fail GMP/ISO Standards?

Many R&D Directors mistakenly believe that simply buying more cabinets is enough. However, international studies and standards have pointed out major risks when using localized cabinets:

A. Failure to Meet JEDEC J-STD-033 (Electronics)

According to the IPC/JEDEC J-STD-033 standard for handling Moisture Sensitive Devices (MSD), frequent opening of the dry cabinet door causes a "Recovery Time" issue. It can take 30-60 minutes for the cabinet to return to < 10% humidity after each opening, leaving components exposed to moisture for long periods, leading to microchip defects.

B. Violation of ISO 14644 & GMP Cleanroom Principles

Standard dry cabinets do not have HEPA dust filtration systems and do not create positive pressure. Fine dust and microorganisms still exist inside the cabinet, violating ISO 14644-1 principles (Air Cleanliness Classification) and WHO GMP guidelines for the Pharmaceutical industry.

2. DeAir Solution: Turning Labs into Standard "Dry Rooms"

DeAir provides an ecosystem of equipment to build standardized laboratories where humans can work directly inside without affecting specimens.

Level 1: Humidity Control 35% - 60% (Medical & Chemical)

Using DeAir.RE Heat-Pump Dehumidifier (Stainless Steel 304 version).

• Advantage: Stainless Steel 304 resists chemical corrosion, is easy to clean, and meets microbiological standards.
• Heat-Pump Technology: Saves 40-60% energy compared to resistive dryers.
• Application: Chemical labs, Vaccine storage, Microbiological culture rooms.

Level 2: Deep Drying < 10% - 30% (Pharma & Lithium Batteries)

For ultra-low humidity requirements, the use of Dezenno Rotor Dehumidifier is mandatory.

• Principle: Uses a Silica Gel Desiccant Wheel to absorb moisture.
• Performance: Achieves a Dew Point down to -60°C, which conventional compressor dehumidifiers cannot reach.
• Application: EV Battery production, Effervescent Pharmaceuticals, Semiconductors.

Level 3: Comprehensive Control (Cleanroom AHU)

Using DeAir AHU (Air Handling Unit) integrating 4 functions: Temperature Control, Humidity Control, Fine Dust Filtration (HEPA), and Fresh Air Supply.
