WineZone Air Handler 4800a Series

Evaporator Coil Coating now included.

For cellars up to 1585cuft

Air Handler System
• Used for L-shaped rooms, long narrow rooms, or where one point source will not properly circulate air throughout the room
• For cellars that will store or mature wine for long periods of time
• Located outside the cellar, the supply and return air is ducted into the room similar to a central air conditioner
• No visible mechanical equipment in cellar
• Ducted units need only supply registers and return air grilles in the cellar leaving more wall space for racking and art work
• Ducting can be placed in soffits if room construction is already complete
• The most quiet style of all refrigeration systems
• Humidification, and dehumidification air handler systems allow for total climate control in the wine cellar
• Accurate, fast acting thermostat controls the refrigeration system and all accessories
• Can be used with either an indoor or outdoor remote condensing unit, moving heat and noise away from the cellar
• Wooden and decorative metal registers available
• Must be installed and adjusted by a qualified HVAC technician
