Dehumidifiers for libraries, document storage

Libraries, document archives, document storage companies etc. require controlled humidity for which we supply a wide range of dehumidifiers. These are generally refrigerant type dehumidifiers. They will be either wall-mounted or floor-mounted models. We can supply any type of dehumidifiers based on your requirements.

How to control humidity in libraries, document storage areas, document archiving areas etc?

The humidity content increases due to many factors such as air conditioning, external humidity, the number of people occupying the area etc. It is extremely important to control humidity in all such areas. The gradual damage caused by humidity will be irreversible for any type of documents, films, microfilms, books etc. In order to reduce humidity in such areas, you can use condensation type dehumidifiers or desiccant type dehumidifiers based on selection criteria. They condition the air inside the area to control humidity on a continuous basis.

Models of dehumidifier for libraries and document archives

Few of our models of dehumidifiers are listed hereunder. In order to decide the right dehumidifiers in terms of capacity and mounting arrangements, you may contact one of our offices. The capacity calculation is based on the size of the room, temperature and present humidity. Also, you need to specify the desired humidity for us to calculate the required capacity.
