How To Keep Cleanrooms Dry and Free from Contaminants?

For cleanrooms, silica gel desiccants are one of the important elements that help in controlling humidity levels. Humidity refers to the amount of moisture present in the air. High humidity levels can increase the contamination rate and negatively impact the quality of products and materials manufactured in a cleanroom. 

To address this, cleanrooms use dehumidifiers to maintain an optimal humidity level. The use of silica gel as a dehumidifying agent is a popular method of controlling humidity in cleanrooms.

Why do we need silica gel for cleanrooms?

Desiccant Silica gel for cleanroom absorbs moisture and helps to reduce the risk of particles and microbes in the air, which can contaminate products or equipment. The moisture-absorbing beads also help to maintain a consistent temperature and humidity level in the cleanroom environment, which is vital for the safety of the products or equipment used in the cleanroom.

The most preferred desiccant for cleanrooms is orange silica gel beads. Orange silica gel beads can be used in various silica gel for cleanroom dehumidifiers, including desiccant and refrigerant dehumidifiers

Desiccant dehumidifiers use a rotating wheel coated with silica gel to remove moisture from the air. This dehumidifier is especially effective in low-humid environments, making it an ideal choice for cleanrooms.

Refrigerant dehumidifiers, on the other hand, use a refrigeration system to condense moisture from the air. Silica gel can be used in conjunction with the refrigeration system to enhance the dehumidifying capabilities of the device. This type of dehumidifier is best suited for use in environments with higher humidity levels.

An important consideration when using silica gel for cleanroom dehumidification is its environmental impact. Silica gel is not a renewable resource, and it is important to dispose of it properly to minimize its environmental impact. Some companies offer recyclable silica gel options that can be regenerated and reused, reducing the waste generated from its use.

Another advantage of silica gel for cleanroom dehumidification is its ability to absorb odours. This makes it a valuable tool for controlling the levels of pollutants and odours in the cleanroom, which can negatively impact the quality of products and materials manufactured in the environment.

Therefore, orange silica gel beads are used where products need protection from moisture and humidity. For example, they are widely used in the breather transformer, leather, electronics, and pharmaceutical packaging industries. However, the orange silica gel bead's moisture absorption capability is 40% of its weight and is available in 2-5mm, 3-5mm, and 4-8mm sizes.

Benefits of silica gel for cleanroom

  1. Enhanced product quality: Silica gel can absorb moisture from the air and prevent it from settling on products, which can damage them. Reducing the amount of moisture in the air reduces the risk of contamination and product degradation.
  2. Improved air quality: Silica gel can help keep the air in a clean room free of dust, dirt, and other contaminants. This helps to maintain high levels of cleanliness and sterility in the environment.
  3. Reduced maintenance: Silica gel can reduce the dusting and cleaning needed to keep the cleanroom in working order. 
  4. Cost savings: Silica gel is inexpensive and can be reused frequently, making it a cost-effective way to keep a cleanroom free of contaminants.
