Chemicals and Pharmaceuticals

The environment in which pharmaceutical products are manufactured plays an important role in determining the quality of products such as medicines, supplements and cosmetics.

The fact that all of these products are meant to keep use healthy or cure us from possible diseases gives us the measure of how important is that those products are of the highest quality. HVAC systems contribute to overall manufacturing process quality ensuring that temperature and humidity in the manufacturing facilities are constantly controlled, to avoid contamination during the manufacturing process.

So, perfect temperature and humidity control in pharmaceutical facilities is necessary for the following reasons. One of the most important is that manufacturing processes for drugs, for instance, usually require different levels of temperature for chemical processes and blend ingredients. This can lead to the generation of heat in excess, which needs to be removed to ensure the safety of the employees and avoid equipment damage. Certain drugs, then, might require cold storage to maintain their properties. That is the case of vaccines, for instance, which need to be stored at low temperatures to preserve their effectiveness. The same vaccines, although requiring cold storage, might need to be stored at a very precise temperature, though.

All this gives us the measure of how important storage is in this kind of application. So much that companies in this sector must comply with regulatory bodies’ guideline. One of them is the World Health organization’s guideline for the storage of pharmaceutical products, which, states pharmaceuticals need to be stored in ventilated and dry environments with temperatures in the range of 15 to 25 C°. But temperature and humidity control are also important to avoid contaminations, as we know pathogens thrive in warm and humid conditions. Humidity, for instance might also increase the level of moisture in drugs, which might lead to a deterioration of the drug itself.
