Dry Room: The Complete Guide

The most important consideration for dry room design is humidity. Humidity could be from the employees, fresh air supply, airlock opening, and moisture from the wall. Zonsteel takes into consideration such measurements to maintain a low humidity cleanroom environment.

To make cleanroom a hermetically sealed system, Zonsteel wall system is airtight sealed. The insulation is rock wool, which is a grade A fire-retardant material, and with good thermal performance. The metal facing on both sides prevents moisture migration. After the two panels are joined, extra sealant will be fixed to reinforce the airtightness.

The air supply and return air duct are tightly sealed and insulated to improve the dry room operations. Zonsteel air duct panel available as 20mm to 100mm size options. The core material is PU or XPS with the faces being an aluminum foil or steel sheet of thickness 0.18mm to 0.6mm.

The fresh air getting into the cleanroom is filtered ensure cleanroom cleanliness is maintained as well as keeping the room at positive pressure.

Zonsteel advocates for setting up an airlock between two dry rooms. The airlock is for normal personnel and for equipment entry. Minimize the airlock opening time and ensure the airlock air is exhausted fully.

A Zonsteel dry room includes walls, ceilings, floor coatings, lighting, controls, and an external penetration process that increases your productivity.

Figure 1 A Completely Installed Dry Room

It is possible to get an idea of what the dry room is all about from the name. A dry room is a structure set up to keep the humidity in the room as low as possible. This is important, especially when your product is sensitive to moisture or easily absorbs moisture.

The dry room can also be an excellent choice for storing a product in a dry environment for a long time.

Other than keeping the moisture and humidity levels low, the dry room will also have particle filters essential for maintaining cleanliness in the room.

Which Industries and Applications Need a Dry Room?

Due to a dry room’s design specifications, you might be wondering where such a space would be used. Here is a list of the application examples where a dry room may be necessary.

– Lithium-ion cell manufacturing plants

– Humidity management for powder manufacturing

– Condensation and rust prevention in precision electronics storage

– Precision electronics parts manufacturing

– Pharmaceutical manufacturing

– Capacitor manufacturing

These are not the only applications for a dry room, as some clients might still have other applications in mind. If that is the case, talk to the team at Zonsteel for more information about customizing the standard dry room to suit your needs.

What is the Range of Humidity for a Dry Room?

The application where you want to use a dry room determines the humidity range. On average, the relative humidity range is 2% to 20% for a dry room.

Talk to technicians at Zonsteel to help you further understand which would be the best humidity range for your applications compared to other applications.

Still, the temperature will be maintained at around 21 degrees Celsius. This is crucial for ensuring that the room is neither too cold nor too hot. Maintaining a steady temperature will also help in keeping the relative humidity within the desired range always.

What are the Components of a Dry Room?

To fully understand how a dry room works, it is best to look at its various components to see how they work in harmony to ensure the dry room works great.

The major components include the following:

The panels

To set up the room, the manufacturer uses insulated sandwich panels for the walls. The use of insulated sandwich panels ensures the dry room can keep working correctly within the stated humidity and temperature range. The most common panel used is rockwool. This material is also a fire retardant in addition to being a good insulator.

Both sides of the panels are also covered with steel profile to prevent any cases of moisture migration. Once two panels are joined, the manufacturer applies more sealant to ensure there is better airtightness in the dry room.

The floor

A dry room needs an anti-static floor as part of making it suitable for various applications. The anti-static floor will absorb the static charges so that the employees or any equipment in the dry room is not harmed.

It should also be strong to support the room’s traffic daily without the need for replacing the floor anytime soon.


The doors will be made using the same materials as the wall panel. The idea is to maintain consistent performance inside the dry room.

It is advisable to have a standard entrance and an emergency door to be used when necessary.

The doors need to have an airlock or a vestibule important for preventing infiltration of moisture into the dry room.

– Sensor

If you have to control the dew point or humidity levels in a dry room, then a sensor that can detect the dew point is necessary. The sensor also works in conjunction with a meter to measure the dew point and a controller to adjust the various parameters to deal with the humidity levels.

It is why you may have to take your time to understand which sensor and dew point is ideal for your operations.

– Conditioning system

The dry room also relies on the conditioning system to work effectively. The desiccant dehumidifier, condensing units, and fans make up the conditioning system.

A desiccant dehumidifier should be designed to have a pH neutral and chemical resistant rotor. The last thing you would want is for it to rust when using in an environment which chemicals such as lithium battery manufacturing.

The fans used in a dry room need a centrifugal airfoil design to make it work better in such an environment. It could also use vibration insulators to keep the vibrations and noise to a minimum.

The condensing unit should be water or air-cooled to work better in a dry room. These components will be designed to work harmoniously to ensure the dry room can maintain the desired humidity range.
