INDUSTRY LEADING

FEATURES / BENEFITS

A competitively priced and creative solution to

design problems.

The 38MGR ductless inverter driven multi−zone system provides

individual comfort control for up to 5 separate zones. Two, three,

four or five space−saving High Wall, Cassette, Ducted Style or

Floor Console fan coils can be matched with one outdoor heat

pump. The indoor fan coils are connected to the outdoor unit by

refrigerant tubing and wires.

The different styles of indoor units can be mounted in several

locations to accommodate the application. This selection of fan

coils permits inexpensive and creative solutions to design problems

such as:

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.

S Commercial add−on jobs where the existing air conditioning

system cannot be stretched.

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 and heating performance at low sound

levels.

Inverter Technology Fast Installation The inverter driven compressor is designed to run at various input power frequencies (Hz) which controls the compressor’s motor speed. Even Temperature – The control package, including the inverter, monitors the outdoor and indoor temperatures as they relate to the selected indoor set point and adjusts the compressor speed to match the load and keep the system operating continuously rather than cycling and creating temperature swings.
