What Is a Dry Room Controlled Environment?

What Is a Dry Room Controlled Environment?

Controlled environments are critical to the success and reliability of various high-stakes manufacturing processes. Dry rooms have stringent control of humidity levels, making them essential in many modern production and research fields.

But why exactly are dry rooms so important, and why is their demand growing across industries? The answer lies in the sensitive nature of the products and processes that require such meticulous environmental control—where even a slight deviation in humidity can lead to costly defects or failures.

If you’re looking to deepen your understanding of dry rooms, their features, and their applications, you’re in the right place. 

What Is a Dry Room?

A dry room is defined by its ability to control and reduce atmospheric moisture to levels that far exceed the capabilities of standard environmental control systems. This is achieved through the use of advanced dehumidification technologies that ensure the air remains dry and stable. Typically, a dry room maintains humidity levels below 1% Relative Humidity (RH), though this can vary based on specific industry requirements.

Moisture can lead to oxidation, contamination, and other forms of degradation in environments where electronic components or other critical items are manufactured. For instance, in the production of lithium-ion batteries, excess moisture can cause unwanted chemical reactions that compromise the batteries’ integrity and safety. 

5 Key Features of Dry Rooms

Dry rooms are equipped with a range of structural and technological features to ensure that the room meets the stringent requirements necessary for controlling humidity at very low levels. Here’s a closer look at some of these key features:

1. Dehumidifiers:

The most critical component of a dry room is the dehumidification system. These systems are highly specialized and capable of reducing and maintaining humidity to levels as low as 1% RH or even lower. Industrial-grade dehumidifiers used in dry rooms operate on the principle of adsorption or refrigeration and are often customized based on specific needs.

2. Airlocks:

Most dry rooms are fitted with airlocks. These airlocks act as buffer zones between the dry room and other parts of the facility. Personnel and materials must pass through these airlocks, where air is carefully controlled to minimize humidity entering the controlled environment.

3. Specialized HVAC Systems:

Apart from standard heating, ventilation, and air conditioning functions, HVAC systems in dry rooms are equipped with additional features to handle extreme dehumidification. These include enhanced filtration systems to remove particulates and contaminants and precision control mechanisms to maintain consistent temperature and humidity levels.

4. Sealed Environment:

Dry rooms are constructed to be as airtight as possible to prevent external air from compromising the controlled environment. This includes the use of vapor barriers and specialized sealants around doors, windows, and other potential air ingress points.

5. Monitoring and Control Systems:

Sensors are strategically placed throughout the room to monitor real-time conditions like temperature and humidity. These sensors are linked to a central control system that automatically adjusts the room’s environment based on predefined parameters, ensuring constant conditions are maintained.

Essential Dry Room Requirements

For a dry room to function effectively, it must meet specific construction and operational requirements. Here are some examples of dry room requirements: 

  • Materials: The construction materials for walls, floors, and ceilings must be selected for their low moisture permeability and resistance to environmental conditions.
  • Maintenance: Regular maintenance of dehumidifiers, HVAC systems, and other critical components is essential to prevent failures that could introduce moisture into the room.
  • Personnel Protocols: Workers entering a dry room need to undergo specific procedures, such as wearing moisture-absorbing garments and passing through air showers, to minimize the amount of humidity they carry into the environment.

Industries and Applications of Dry Rooms

Dry rooms are pivotal in industries where even minor humidity can compromise product quality, safety, or efficacy. Here’s how they are utilized in various sectors:

Electronics Manufacturing:

  • Semiconductor Fabrication: Semiconductors are extremely sensitive to moisture because even trace amounts can lead to oxidation of the silicon wafers. Dry rooms ensure these components are manufactured and assembled in a moisture-free environment.
  • Assembly of Sensitive Electronics: Components such as OLED panels and precision sensors require assembly in dry rooms to prevent malfunction or degradation caused by moisture.

Battery Production:

  • Lithium-Ion Batteries: The production of lithium-ion batteries is one of the most critical applications for dry rooms. Exposure to humidity during manufacturing can cause unwanted chemical reactions, leading to reduced battery efficiency and potential safety issues. 
  • Battery Testing and Packaging: Batteries must be tested and packaged in low-humidity environments to ensure they meet safety and performance standards without degradation.

  • Material Storage and Handling: Aerospace components often include materials that are highly sensitive to moisture, such as composite materials and adhesives. Dry rooms are used to store and handle these materials to prevent moisture absorption that can compromise structural integrity.
  • Equipment Manufacturing: Many aerospace devices, including satellites and sensors, must be assembled in ultra-low humidity environments to ensure they function reliably in the harsh conditions of space.

Food and Beverage:

  • Powdered Products: Foods sold in powdered form, like milk powder and coffee, often require dry rooms during the packaging process to prevent clumping and microbial growth induced by moisture.

Dry Rooms vs. Cleanrooms: What’s the Difference? 

Both dry rooms and cleanrooms are controlled environments designed to minimize specific environmental variables that otherwise compromise the quality or functionality of sensitive products. 

Despite their similar purpose, they serve distinctly different functions and are designed with varying priorities in mind:

  • Humidity vs. Particulate Control | The primary focus of a dry room is to control humidity levels. Cleanrooms primarily focus on minimizing particulate contamination in the environment. They are classified based on the number and size of particles permitted per volume of air.
  • Implications for Design | The design of a dry room involves selecting materials and constructing barriers that prevent any form of moisture ingress, including specialized dehumidification systems and sealed constructions. In cleanrooms, the design focuses on smooth, cleanable surfaces, laminar air flow, and sophisticated air filtration systems that remove contaminants from the air. 
  • Use and Applications | Dry rooms are essential in industries where even minimal moisture can cause significant product degradation, such as in lithium-ion battery manufacturing. Cleanrooms are indispensable in the production of semiconductors and any other environment where the presence of microscopic particles can result in defective products.

Your required cleanroom classifications and standards will depend on your industry. The requirements will vary depending on what size particles need to be filtered, the sources of contamination present, and the recommended air change rate. 

If your industry is government-regulated, you can check applicable regulations for the required classification. If there is no government-mandated or industry default classification, you’ll need to determine the appropriate classification based on your application, and we can help with that.

2. How are cleanrooms classified?

Two different classification scales are generally used for cleanrooms: the U.S. General Service Administration standards (FS209E) and the International Standards Organization (ISO) classifications. The classes are determined by the maximum acceptable numbers of particles (by size) in the air per cubic meter. 

3. What are the ISO classes?​

The ISO classification system has eight classes and defines the level of cleanliness based on the concentration of airborne particles. Here’s a breakdown of the eight ISO classes from least controlled (ISO Class 8) to most controlled (ISO Class 1):

  • ISO Class 8: This class allows the highest concentration of airborne particles. The maximum allowable particle count is 3,520,000 particles per cubic meter of air (0.5 micrometers and larger in size).
  • ISO Class 7: The maximum allowable particle count is 352,000 particles per cubic meter of air (0.5 micrometers and larger). 
  • ISO Class 6: The maximum allowable particle count is 35,200 particles per cubic meter of air (0.5 micrometers and larger).
  • ISO Class 5: The maximum allowable particle count is 3,520 particles per cubic meter of air (0.5 micrometers and larger).
  • ISO Class 4: The maximum allowable particle count is 352 particles per cubic meter of air (0.5 micrometers and larger). 
  • ISO Class 3: The maximum allowable particle count is 35 particles per cubic meter of air (0.5 micrometers and larger).
  • ISO Class 2: The maximum allowable particle count is 7 particles per cubic meter of air (0.5 micrometers and larger). 
  • ISO Class 1: The most stringent of all, ISO Class 1 cleanrooms allow only one particle per cubic meter of air (0.5 micrometers and larger).

4. How often do I need to test my cleanroom to see if it’s meeting classification requirements?

ISO classifications require that air pressure difference and flow be tested every 12 months. Particle count tests must be performed every 12 months for ISO Class 6 and above and every six months for ISO Class 5 and below. 

There are also tests recommended for all classes every 24 months: installed filter leakage, containment filter leakage, recovery, and airflow visualization. These tests are regulated by ISO document 14644-2 Cleanroom Testing and Compliance.

5. How often do I need to have my cleanroom inspected?

How often you need your cleanroom inspected depends on your classification. The more stringent classifications will require inspection more often. Inspection may coincide with compliance testing, which may occur every six or 12 months, depending upon the cleanroom classification.

6. How does cleanroom classification affect my budget?

The more stringent the classification, the greater the cost of the cleanroom. Strict classifications require more air, energy, advanced technology, and equipment. For a more detailed breakdown of the costs, see How Does Cleanroom Classification Affect Your Cleanroom Budget?

7. Can I redesign my cleanroom if my required classifications change?

Yes, of course! Every company is bound to evolve, and our cleanrooms can change right along with them. All Angstrom cleanrooms are modular, meaning they can be expanded or decreased in size, components can be added or removed, and any other design changes can be made.
