Industrial dehumidifiers can be used for many applications including:

• Industrial applications e.g. warehouses, store rooms. 
• Commercial applications e.g. Large shopping areas, Museums, Galleries
• Swimming Pools

They are a perfect way to keep the relative humidity down in a room to prevent any damage from occuring to any valuables in the case of storage rooms and galleries, and damage to any fixtures keep the atmosphere more pleasant in a swimming pool area.  All industrial dehumidifiers don't have a water collection bucket as they are designed to rmeove moisture from the air at such a rate it would be impractical to collect it in a bucket to be emptied out every half an hour or so, the continual drain can be hungoutside or drained into a pipe inside the buliding, the water that is coming out of an industrial dehumidifier is so clean it could be used for watering plants

Swimming Pool Dehumidifer

A lot of people who have indoor pools put in place generally don't think about having a swimming pool dehumidifier, this would be a big mistake as the water will be continually slowly evaporating out of the pool and condensing on the cold walls and windows of your pool room.  A swimming pool dehumidifier will elimate this problem as the evaporating water will be drawn in by the swimming pool dehumidifier and drained away outside.
