Description
This MRCOOL Olympus ducted air handler is the 18,000 BTU indoor unit for one zone of a professionally installed multi-zone system, hidden above the ceiling and connected to the room by ductwork.
Highlights
- Installs out of sight above the ceiling, with only the supply and return grilles visible in the room
- Distributes air through ductwork, so one zone can serve more than one room or an awkward layout
- Sized for a larger area, or several smaller rooms served from one zone
- Takes a 1/4" x 1/2" line set, shared with the 12,000 BTU handler
- Heat pump operation, providing both cooling and heating in the zone
Details
Avermont Direct is an authorized MRCOOL dealer. A ducted handler suits rooms where nothing should be visible on the wall or ceiling, and ordering it on its own lets a contractor use it for one zone while the rest of the system stays wall mounted or cassette. It is backed by the manufacturer's warranty, and full terms are set out in the product documentation.
