The Islandaire Dr Ptac option is available in Islandaire’s EZ Series DR (42- by 16-inch PTAC/PTHP) product line and in the EZ Series VR (vertical unit). The Dr PTAC module is an innovative choice for conditioned make-up air for new and existing hotels, healthcare centers and other facilities across the U.S., Canada and the Caribbean.
This separate module is designed to constantly bring in fresh air into the living space and when the relative humidity level outside reaches a range of 40 percent to 100 percent the additional compressor is engaged to condition the fresh air as it enters the room. The benefits of using the Dr PTAC in new buildings results in a reduced size of the DOAS (dedicated outdoor air system), increased reliability of providing make-up air to the property, extension of FF&E and soft goods life and qualifies for LEED points in four areas, the company said.
In existing buildings the Dr. PTAC benefits include the elimination of mold, mildew, odors and smells. Fresh air that travels across the room creates a neutral or positively pressurized room restricting unwanted pollutants and contaminates from entering the room. Existing properties that have Dr PTAC installed have seen a 25 percent to 50 percent reduction in room humidity levels and an overall energy reduction of 10 percent to 20 percent due to the reduced load in the rooms.
