Over-cooling means air often must be reheated before it can be distributed into the conditioned space. And that substantially increases operating costs. Hickory Orthopedic Clinic chose option two and installed a natural gas desiccant dehumidification system for several reasons. The desiccant wheel extracts the moisture by using natural gas to dry out and regenerate the desiccant wheel before sending it through another cycle. The cost of overcooling and re-heating air with a conventional large chiller is significant compared to a desiccant unit.
Natural gas is one of the most economical fuel sources.
