Friedrich Air Conditioning, a leading room air conditioner manufacturer for more than six decades, is proud to introduce a completely re-engineered PTAC for 2011. Frequently used in lodging, senior care, dormitories, military housing and some residential applications, PTACs are 42-inch-wide, through-the-wall air conditioners and heat pumps. Because PTACs can be up to 50 percent shallower than other through-the-wall solutions, they install flush with exterior walls and use little interior floor space. And, the slide-out chassis design has maintenance benefits for facilities managers who need to keep rooms comfortable for their occupants. Replacement units can be installed and operating in as few as 10 to 15 minutes. No technical expertise is necessary. Completely redesigned and re-engineered, this Friedrich PTAC also hits the mark with a feature set that delivers reliable operation and superior comfort.
