Dew point of compressed air in pharmaceutical industry

Note on the dew point of compressed air in the pharmaceutical industry

the dew point is a key indicator of the moisture content in compressed air, which refers to the temperature at which the gas cools to the point at which water vapor begins to condense into liquid water. The lower the dew point, the lower the moisture content in the compressed air.

Requirements for compressed air dew point in pharmaceutical industry
the pharmaceutical industry has strict standards for the cleanliness of the production environment. As a key auxiliary medium, the dew point control of compressed air is particularly important:

• if the water content of the compressed air is too high, it may cause the medicine to be damp, the packaging material to deform, or provide conditions for the breeding of microorganisms, affecting the quality of the medicine;
• in the aseptic production, drug filling and other direct contact with drugs, low dew point compressed air can avoid moisture condensation pollution products;
• if the compressed air pipeline is rusted due to moisture condensation, particulate matter may fall off and pollute the production environment.

Grantkering air compressor and dew point control
granklin water lubricated single screw air compressor adopts oil-free design, no lubricating oil is involved in the compression process, and the water content of the output compressed air itself is controllable and stable. The matching structure of the single screw and the star wheel can reduce the temperature fluctuation of the gas during the compression process and provide a more stable foundation for the subsequent drying treatment.

Key measures to achieve low dew point
if you need to meet the more stringent dew point requirements of the pharmaceutical industry (e. g. -40°C or lower), it is usually necessary to combine subsequent drying equipment:

• freeze dryer: The water vapor in the compressed air is condensed and discharged by cooling, which is suitable for scenes with low dew point requirements;
• adsorption dryer: The use of adsorbents (such as activated alumina, molecular sieves) to remove moisture in depth can achieve a lower dew point (such as below -60 ℃) to meet high standards such as aseptic production.

Advice and support
pharmaceutical companies can choose matching drying equipment according to specific production links (such as direct contact with drugs and non-direct contact), and regularly detect the dew point of compressed air to ensure compliance with the "Good Manufacturing Practice" (GMP) or ISO 8573 standards.

Granklin air compressor is committed to providing users with clean and stable compressed air solutions. It can provide full technical support from equipment selection to drying treatment in combination with the needs of the pharmaceutical industry, helping enterprises to achieve compliance production and quality control objectives.
