A myriad of new energy-reduction and environmentally friendly dehumidification technologies have been introduced to the indoor swimming pool market in the last 10 years. These innovations not only provide significant advancements in system performance and reliability, but also considerably reduce operating expenses. These systems also provide natatorium owners/operators a quick return on investment (ROI), which has prompted more facilities to consider upgrading their existing dehumidification equipment even before its useful lifecycle is over. For new construction projects, these systems can potentially save hundreds of thousands of dollars over the equipment’s lifecycle.
