In the pharmaceutical industry, ensuring the quality and safety of products at every stage is crucial for protecting human health. "Weighing rooms," where active pharmaceutical ingredients (APIs) and excipients are measured in correct proportions, play a key role in ensuring the efficacy, safety, and quality of medications. Maintaining proper humidity control in weighing rooms is essential, as the amount of moisture in the air can affect the weight of the products being measured. In humid air, products can absorb moisture, increasing their weight and leading to significant errors, especially in small doses like milligrams and micrograms.
Some pharmaceuticals and active ingredients are sensitive to humidity and can deteriorate or lose their properties in humid environments. For instance, certain powdered drugs can harden or clump in humid conditions, resulting in unwanted chemical reactions and transformations. Weighing rooms are designed to prevent cross-contamination, with climate control systems ensuring that temperature and humidity levels are continuously monitored and maintained within set limits.
In weighing rooms where sensitive weighing stations are located, uncontrolled humidity can lead to microbial growth and contamination of drugs. High relative humidity can increase electrostatic charges, causing powdered materials to stick together and produce inaccurate weighing results. Desiccant-type industrial rotary dehumidifiers reduce the humidity in the air, ensuring weighing accuracy and product stability, reducing microbial growth risk, preventing electrostatic charges, and improving working conditions.
As NKT – Humidity Control Technologies, we represent the Italian company TFT, which has developed silica gel rotary dehumidifiers specifically for weighing rooms. Integrating these dehumidifiers into ventilation lines leading to weighing rooms offers an optimal design, especially for retrofitting existing systems.
When selecting a dehumidifier for weighing rooms, consider the following:
- Room Size: The capacity of the dehumidifier should be suitable for the room size.
- Airflow to the Room: The dehumidifier should match the airflow to the room.
- Desired Humidity Level: The dehumidifier must maintain the desired humidity level in sync with the airflow.
- Noise Level: Since the dehumidifier will be located near the room, it should not create noise disturbances.
- Energy Consumption: The dehumidifier should be energy-efficient.
- Dimensions: The dehumidifier should fit within the space, often being installed on the air duct leading to the weighing room. It should have low height and a vertical rotor configuration.
Dehumidifiers are an essential part of climate control in weighing rooms in the pharmaceutical industry. Properly selected and integrated dehumidifiers help maintain weighing accuracy and product stability, preserving the quality and safety of pharmaceuticals.
