FEATURES / BENEFITS
AN INEXPENSIVE AND CREATIVE
SOLUTION TO DESIGN PROBLEMS.
The 38HDR(QRR)/40QAC(QAQ) series duct- -free split systems
are a matched combination of an outdoor condensing unit and an
indoor fan coil unit connected only by refrigerant tubing and wires.
The ceiling- -suspended fan coils are ideal for retrofit and
modernization projects where it is impractical or prohibitively
expensive to run ductwork and where there are no false ceilings or
wall space available.
