Quantum Ultra Ducted Ceiling Concealed (RYB-20) OverviewUpdated 6 hours ago
Introduction
The Quantum Ultra Ducted Ceiling Concealed (RYB-20) series is a mini split system providing hidden heating and cooling for multiple rooms through a single ducted unit.
The ducted ceiling concealed system has an average 20-SEER2 rating, and is factory-precharged with environmentally-friendly R-454B refrigerant.
Ductable to Multiple Rooms
This system can provide heating and cooling to multiple rooms via ducting, enabling warmed or conditioned airflow all throughout the home. With its ceiling concealed design, only the wired controller and air grilles are visible to the occupants.
Flexible Air Intake
The air handler can be easily modified to pull in return air from the bottom or rear side. Simply move the air intake cover to the side that will not be used and you're all set.
High Quality Built-in Components
The air handler features an innovative blower wheel design, improving the airflow at the air outlet. This series includes a built-in drainage pump that can lift condensate water up to 30 feet (9.1 m).
Precision Temperature Control
With the fully DC inverter design combined with our latest 540L wired controller, the set temperature inside the room can be maintained accurately, within +/- 2°F tolerance.
