Benefits
Humidity control in the pharmaceutical industry is essential in many production and testing processes to maintain quality and reduce waste.
Product stability
Humidity control helps during storage time, ensures drug quality and safety.
Precise manufacturing
Optimal humidity protects the hygroscopic materials and supports the processes.
Prevents contamination
Humidity control prevents degradation and microbial growth.
Humidity control in the pharmaceutical industry
Prevention of static electricity
Levels of humidity below 40% RH can lead to static build-up. The results of this include materials adhering to each other on the production line and not locating correctly inside of packaging. A humidity level of between 55 - 65% RH will significantly reduce the probability of electro static discharge, which is vital for sensitive electronic equipment or where flammable gases or substances are being used.
Stability testing
Regulations on accelerated or longterm stability testing mostly require humidity to be controlled within a tolerance of ±5% RH. If the condition of the atmosphere falls outside this window, it can result in a test having to be restarted. This is expensive and can even delay the launch of a new product.
Humidification and dehumidification in tablet coating
Successful coating of a tablet largely depends on the composition of the tablet at the time of exposure to its coating. If the tablet’s surface is too dry, due to incorrect humidity levels, the coating will not adhere correctly. Likewise if the humidity post coating is not optimal, the coating may dry too rapidly, detrimentally affecting its properties.
Humidity control in fluid bed drying
Consistent and responsive humidity control in Fluid Bed Drying processes results in the product’s moisture content reaching the target level more rapidly and with less wastage through over or under drying. Close control resistive steam humidifiers running on pure RO water can provide a precision of ±2% RH.
Dehumidification in tablet pressing processes
Production and processing procedures in the pharmaceutical industry have always been associated with special requirements: this also applies to the manufacture of tablets. Even the raw materials require constant environmental parameters in order to maintain their effectiveness. To avoid the risk of the tablets being contaminated by dirt particles, germs, or spores in the air during the manufacturing process, a relative humidity of 35–50 percent at air temperatures of 21–27 degrees Celsius is optimal.
Use cases
Anti-static and ESD prevention
Low humidity increases static build-up because dry air is an insulator, making electrostatic discharge (ESD) more likely. Maintaining 40–60% relative humidity helps dissipate charges and significantly reduces ESD risk.
Reliable operations start with a controlled environment
Humidity fluctuations can cause static discharge, material distortion, and premature wear on sensitive equipment—all leading to costly downtime. By maintaining consistent humidity, it protects both the machinery and the materials they process, ensuring smoother production, fewer interruptions, and maximum operational uptime.
Prevent evaporative losses
Organic materials have an internal moisture content and will lose moisture to the atmosphere when exposed to air with a low humidity. Humidifiers are used to create an environment with perfect balance between the material’s internal moisture content and the air’s relative humidity.

Evik Diagnostics, Ottawa
Evik¯Diagnostics Innovations, a biotechnology leader in Ottawa, faced stringent challenges: producing lyophilized assay reagents (DxSpheres) requires dryroom conditions with relative humidity below¯10%. Their prior dehumidification systems failed to deliver consistent reliability across their 2,600¯sq¯ft of production and research space. Condair stepped in with its DA¯dehumidifiers (400/208 units) and local support to deliver the ultra‘low RH stability required. The installation, carried out by Longhill¯Energy and Atwood‘Gravel, integrated seamlessly with ongoing operations. With Condair in place, Evik achieved maintenance‘light operation delivering stable sub‘10% RH, enhancing product strength and consistency while reducing environmental fluctuations. The solution not only solved immediate moisture control issues but also provided a platform for growth with dependable humidity performance for the most exacting manufacturing environment.
