Indoor pools are widely used in hotels, communal living areas in sites and residences, sports complexes and social facilities. During the project design phase, our company engineers carefully focus on the filtration and disinfection systems due to the intensive use of indoor pools. Another issue that increases customer satisfaction in indoor pool projects is the heating of pools. The pool water temperature recommended by our project teams is 26-28ºC. In order to remove the relative humidity in the indoor pool area, an effective ventilation and dehumidification process should be performed. Selection of dehumidification devices and selection of suitable sizes is of great importance for our company.
