PET Sterile Cold Storage Clean Room Construction Standards

When producing products with extremely high environmental requirements, the PET sterile cold storage clean room plays a crucial role. For Guangzhou Cleanroom Construction Co., Ltd., a manufacturer specializing in purification equipment, it is of great significance to deeply understand its construction standards. Today, let's step into the world of PET sterile cold storage clean room construction.

The cleanliness of the PET sterile cold storage clean room is related to product quality. It is usually classified according to the international standard ISO 14644. Common levels include ISO Class 5 (equivalent to Class 100) and ISO Class 7 (equivalent to Class 10,000). In such a workshop, there are strict restrictions on the number of dust particles in the air. For example, ISO Class 5 requires that the number of particles with a size of 0.5μm or more per cubic meter does not exceed 3,520. This is a basic condition to ensure that the products are sterile and free from contamination.

The temperature of the cold storage workshop is generally controlled between 2 - 8°C to meet the storage needs of some temperature - sensitive products, such as pharmaceuticals and food. Precise temperature control depends on an efficient refrigeration system and accurate temperature monitoring equipment to ensure that the temperature fluctuation in the workshop is within a minimal range.

The relative humidity is usually maintained at 45% - 65%. Appropriate humidity can prevent products from getting damp and deteriorating, and at the same time avoid the generation of static electricity due to low humidity, which affects production safety and product quality. Advanced humidification and dehumidification equipment are used to achieve precise humidity control.

In key production areas, the unidirectional flow air - flow organization form is often adopted. Air is sent out from high - efficiency filters and flows at a uniform speed and direction, quickly discharging dust particles and other pollutants from the workshop and effectively reducing the accumulation of pollution.

In some auxiliary areas, the turbulent flow form can be adopted. Although the purification effect of turbulent flow is slightly inferior to that of unidirectional flow, it can meet certain cleanliness requirements and the cost is relatively low. By reasonably arranging air supply outlets and air return outlets, the air - flow distribution in the workshop is ensured to be uniform.

Materials that are non - slip, corrosion - resistant, and easy to clean, such as epoxy self - leveling floors, should be used. Its seamless feature can effectively prevent the growth of dust and bacteria and has good wear resistance and chemical corrosion resistance.

Color steel plates are generally selected. The surface is smooth and easy to clean and disinfect. At the same time, it has good thermal insulation performance and can maintain the temperature stability in the workshop.

The ceiling also adopts color steel plates, which are closely connected to the walls to ensure the airtightness of the entire workshop and prevent external pollutants from entering.

Constructing a PET sterile cold storage clean room is a complex and rigorous process. Each standard is related to production safety and product quality. Guangzhou Cleanroom Construction Co., Ltd., with professional technology and rich experience, is committed to creating clean rooms that meet high standards for customers and helping enterprises produce higher - quality products.
