INDUSTRY LEADING
FEATURES / BENEFITS
AN INEXPENSIVE AND CREATIVE
SOLUTION TO DESIGN PROBLEMS.
The 38HDF(QRF) / 40QNC (QNQ) 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 fan coil is mounted on the wall, near the ceiling. This
selection of fan coils permits inexpensive and creative solutions to
design problems such as:
S Add--ons to current space (an office or family room
addition)
S Special space requirements
S When changes in the load cannot be handled by the
existing system.
S When adding air conditioning to spaces that are heated
by hydronic or electric heat and have no ductwork.
S Historical renovations or any application where
preserving the look of the original structure is essential.
These compact indoor fan coil units take up very little space in the
room and do not obstruct windows. The fan coils are attractively
styled to blend with most room decors. Advanced system
components incorporate innovative technology to provide reliable
cooling performance at low sound levels.
