How a Ducted Split System Works

A ducted split wine cellar cooling system divides the unit into two parts: an evaporator near the cellar and a condenser that can be placed remotely, even outdoors. They are joined by a refrigerant line set, and ductwork carries conditioned air into the wine room, so the cellar stays quiet and vibration-free.

It is the most flexible Wine Guardian format, sized from roughly 3,485 to 15,785 BTU across the DS and Pro SP models for residential, restaurant, and commercial cellars. Within the broader wine cellar cooling unit range, a ducted split is the answer when a mechanical room is tight, condenser air is hard to exhaust, or duct runs are long.

Our Most Flexible Cooling System

A ducted split wine cellar cooling system splits the unit into two separate sections, an evaporator near the cellar and a condenser that can be located remotely, even outdoors. Because the noisy condensing components sit away from the wine room, the cellar stays quiet and vibration-free.

It is the most adaptable Wine Guardian format. With the evaporator and condenser separated, a ducted split fits projects where a mechanical room is tight, where condenser air is hard to exhaust, or where duct runs are long. The page below explains how it works and which capacity fits your space.

Ducted Split Key Features and Benefits

Quiet and vibration-free - Wine Guardian Dealer

Quiet and Vibration-Free

The condenser sits away from the cellar, so the wine room stays silent.

Flexible installation - Wine Guardian Dealer

Maximum Install Flexibility

For tight mechanical rooms, hard-to-exhaust spaces, and long duct runs.

Precise temperature control - Wine Guardian Dealer

Precise Temperature

Air-sensing control monitors the cellar 24/7.

Integrated humidity - Wine Guardian Dealer

Outdoor-rated condenser - Wine Guardian Dealer

Outdoor-Rated Condenser

Built to withstand outside temperatures below 40 degrees Fahrenheit.

Field serviceable - Wine Guardian Dealer

Fully Field Serviceable

Removable panels, front controls, and a condenser sight glass.

Engineered for Maximum Flexibility

By separating the evaporator and condenser, a ducted split can be installed where a single cabinet will not fit. It is built for mechanical rooms with limited space, locations where condenser air is difficult to exhaust, and projects that need long duct runs.

The evaporator and condenser connect through refrigerant copper tubing, a familiar process for licensed contractors. Multiple duct configurations are possible without removing the fan motor or other internal components.

When to Choose It

When a Ducted Split Is the Right Call

Tight mechanical room

When there is not enough space for a single self-contained cabinet, the compact evaporator and a remote condenser fit where a one-piece unit cannot.

Condenser air hard to exhaust

When the install location cannot easily shed warm air, the condenser can be moved to a better spot, including outdoors.

Long duct runs

When the unit must sit far from the cellar, the split design and ductwork keep strong air distribution across the distance.

Need specialty or low-temperature performance? The Pro SP series extends the ducted split range for demanding applications. For an all-in-one cabinet, compare self-contained ducted units, or for a smaller cellar see through-the-wall units. You can also see all cooling system formats in one place. Final sizing, line set routing, and heat rejection should be confirmed with a licensed HVAC professional.

Control

Full Control, Any Room

The remote interface controller uses air-sensing technology to monitor temperature and humidity. With Wireless2Base technology you can place the controller in a dining room, den, or kitchen, and add remote sensors for accurate readings when it sits outside the wine space.

Humidity

Humidity, the Key to Wine Preservation

Mold, loss of liquid, and dried out corks are some of the ways improper humidity degrades wine. A Wine Guardian humidifier attaches directly to the ducted split system to add moisture back into the cellar when it drops too low.

Frequently Asked Questions About Ducted Split Systems
How does a ducted split wine cellar cooling system work?

A ducted split system has two separate sections, an evaporator near the cellar and a condenser that can be located remotely or outdoors. They are joined by a refrigerant copper line set, and ductwork distributes the conditioned air into the wine room.

What is the difference between a ducted split and a self-contained ducted system?

A self-contained ducted unit houses everything in one cabinet. A ducted split separates the evaporator and condenser so the condenser can be placed remotely, which suits tight mechanical rooms, spaces where condenser air is hard to exhaust, and long duct runs.

Where can the condenser be installed?

The condenser can be located remotely, including outdoors. Wine Guardian condensers are built to withstand outside temperatures below 40 degrees Fahrenheit. Confirm placement and routing with a qualified professional.

Is a ducted split system DIY friendly?

Wine Guardian recommends that a licensed contractor install ducted split units, because the evaporator and condenser are joined by a refrigerant line set similar to a residential mini split.

What size ducted split system do I need?

Capacities run from roughly 3,485 to 15,785 BTU across the DS and Pro SP models. Correct sizing depends on cellar volume, insulation, glass area, and ambient temperature, so confirm capacity with Wine Guardian's cooling calculator and a qualified HVAC professional.

Can a ducted split system control humidity?

Yes. A Wine Guardian humidifier attaches directly to the system, and the remote interface controller uses air-sensing technology to monitor both temperature and humidity in the cellar.

Is the ducted split only for residential wine cellars?

No. Ducted split systems suit residential, restaurant, and commercial applications, and the Pro SP series extends the range for specialty and low-temperature needs.

Not Sure If a Ducted Split Fits Your Cellar?

Talk to a wine cooling specialist about capacity, condenser placement, line set routing, and duct design for your space. This guidance is general and intended to help narrow the selection. Final sizing, installation design, and electrical requirements should be confirmed with Wine Guardian documentation and a licensed HVAC professional.
