WRRAH 6200a Split Air Handler – Outdoor Condenser no line set


Ducted units are ideal for Lshaped, long and narrow rooms, or any space where one point source of air won‘t properly circulate. These units are also perfect for cellars storing or maturing wine for extended periods of time. With these units, no visible mechanical equipment is needed in the cellar, as supply and return air is ducted into the room in a similar fashion to a central air conditioner. This leaves more wall space for racking and artwork. If the room is already complete, ducting can be placed in the soffits. This type of refrigeration system is the quietest and provides accurate and fastacting thermostat controls. Additionally, a humidification and dehumidification air handler system allows for total climate control in the wine cellar. The ducted unit can be used with either an indoor or outdoor remote condensing unit, which moves the heat and noise away from the cellar. Decorative wooden and metal registers are also available. However, installation and adjustment of the unit must be done by a qualified HVAC technician.
