Humidity control is often essential to the smooth running of cold stores, but the type
of humidity control varies from one application to another. John Barker of Humidity Solutions explains why some require dehumidification while for others humidification is the order of the day.
GIVEN THE RELATIONSHIP between temperature and relative humidity (RH), controlling RH in any application is a precise science. In cold stores, however, humidity control can be particularly challenging and certainly needs to be aligned to the purpose of each store.
For instance, in some cases dehumidification will be required to prevent ice formation, while in others humidification may be a requirement to maintain the required conditions for the items being stored.
