The two companies have begun testing the use of plastic heat exchangers in desiccant air conditioners in high-salt and high-humidity environments, for controlling moisture levels for outside air to furnish required ventilation for building occupants.

Applied Building Technologies (ABT) Division of PowerCold’s wholly owned subsidiary Ultimate Comfort Systems has installed DuPont Caltrel® heat exchanger coils on systems in three buildings in Florida. These are the Don Cesar Hotel in St. Petersburg, and the Elks Lodge and Mike’s Pizza and Deli in Largo.
