Wine Guardian WG75WC Water Cooled Wine Cellar Cooling Unit 50 HZ

Q: What does “water-cooled” mean in this system?

Water-cooled systems use a water source (such as a chilled loop or cooling tower) to remove heat instead of venting it into surrounding air. This is ideal for spaces with limited ventilation or no access to exterior exhaust.

Q: What is the significance of 50 Hz in this model?

The 50 Hz electrical frequency is standard in many parts of the world outside North America. This unit is specifically designed for international use in countries with 220-240V/50 Hz power standards.

Q: Is this a self-contained system?

Yes. The WG75WC is a fully self-contained, ducted system — meaning all major components (evaporator and condenser) are housed in one unit, and conditioned air is delivered via ductwork into the cellar.

Q: Does the WG75WC require professional installation?

Yes. Installation must be performed by a licensed HVAC technician, especially due to the water cooling connections and electrical setup. Proper installation is also required to activate the warranty.

Q: Is the system quiet when operating?

Yes. Because it is ducted and water-cooled, the WG75WC offers exceptionally quiet performance, making it suitable for residential, entertainment, or display environments.

Q: What warranty is included with the WG75WC?

Wine Guardian provides a 2-year parts and labor warranty. Warranty coverage is valid only with professional installation and product registration."]

Wine Guardian Water-Cooled Ducted Wine Cellar Cooling Systems

Wine Guardian WG75WC Water-Cooled Wine Cellar Cooling Unit - 50 Hz

This item is no longer available. The recommended replacement model is the Wine Guardian D050WC Ducted Water Cooled Wine Cooling Unit - 60 Hz.

The Wine Guardian WG75WC Water-Cooled Wine Cellar Cooling Unit is a fully ducted, self-contained wine cellar cooling system designed for medium-sized residential and commercial wine cellars from 18 to 85 cubic meters. It uses water-cooled condensing technology to remove heat through a year-round water source instead of exhausting warm air into an adjacent room.

This 50 Hz model is commonly used in Europe, Asia, Africa, Australia, and New Zealand. For North and South America, a 60 Hz model such as the Wine Guardian D050 Ducted Wine Cellar Cooling Unit - 60 Hz is generally recommended.

Fully ducted, self-contained water-cooled system
Designed for 18-85 m³ wine cellars
Cooling capacity: 0.70-1.421 kW
Ideal for geothermal, cooling tower, and year-round water source applications
Remote equipment placement for a quieter wine cellar
50 Hz international electrical configuration

What Is the Wine Guardian WG75WC?

The Wine Guardian WG75WC is a water-cooled ducted wine cellar cooling system built for wine rooms where traditional air-cooled heat exhaust is not practical. Instead of rejecting heat into the surrounding air, the system transfers heat through a controlled water source, making it suitable for geothermal systems, cooling towers, lake water applications, and properties with reliable year-round water infrastructure.

Because the WG75WC is fully ducted, the cooling equipment can be installed outside the visible wine cellar area. This helps preserve the design of luxury wine rooms, restaurant cellars, and commercial storage spaces while maintaining stable storage conditions for wine collections.

Recommended Applications

Medium-sized residential wine cellars
Commercial wine storage rooms
Restaurant wine cellars
Hospitality wine rooms
Luxury homes with hidden cellar equipment
Geothermal cooling applications
Cooling tower installations
Projects with reliable year-round water sources

Not Recommended For

Projects without a dependable water source
Wine cabinets or beverage refrigerators
Through-the-wall installations
Non-ducted cellar designs
Very small wine rooms
Projects requiring the simplest possible installation
North or South American installations requiring 60 Hz power

Why Choose a Water-Cooled Wine Cellar Cooling System?

Water-cooled wine cellar cooling systems are an alternative to air-cooled systems when heat exhaust is difficult to manage. They are especially useful in projects where the cooling unit cannot easily reject warm air into a nearby mechanical room, garage, basement, or exterior venting location.

No Traditional Heat Exhaust

Transfers heat through water instead of exhausting warm air into an adjacent room.

Ideal for Geothermal Applications

Works well with geothermal loops, cooling towers, lake water systems, and consistent water sources.

Quiet Wine Cellar Design

The ducted layout allows the equipment to be installed remotely from the wine cellar.

Clean Visual Appearance

Only supply and return air grilles are typically visible inside the cellar.

Advantages

Eliminates traditional condenser heat exhaust requirements
Excellent fit for geothermal and cooling tower projects
Remote equipment placement supports quieter cellar operation
Fully ducted design helps preserve cellar aesthetics
Self-contained unit simplifies the system architecture compared with split systems
Compatible with optional humidification solutions
Designed for field serviceability

Limitations

Requires a reliable year-round water source
Professional installation is strongly recommended
More infrastructure is required than a standard air-cooled system
Not suitable for non-ducted installations
50 Hz configuration is not the standard choice for North or South America
This model is discontinued and should be replaced with a current equivalent where available

Installation Requirements

Contractor installation is recommended. Wine cellar cooling systems must be sized and installed according to cellar volume, insulation quality, vapor barrier performance, ambient conditions, ducting layout, and water-source availability.

Properly insulated wine cellar envelope
Continuous vapor barrier system
Dedicated electrical service: 240/1/50
Flexible ductwork installation
Condensate drain connection
Reliable year-round water source
Water temperature range from 45°F (7°C) to 85°F (29°C)
Adequate access for service and maintenance
Professional heat-load calculation before final selection

If your project is located in North or South America and requires a 60 Hz system, consider the Wine Guardian D050 Ducted Wine Cellar Cooling Unit - 60 Hz.

Water-Cooled System Features

Water-Cooled Operation

Water-cooled systems eliminate the need for conventional heat exhaust, making them ideal for wine cellar projects with geothermal sources, cooling towers, lake water systems, or dependable year-round water supplies.

Humidity Management Recommendations

Proper humidity is important for long-term wine storage. Temperature control alone is not always enough, especially in cellars where cork condition, evaporation control, and label preservation matter. Learn more in our guide to The Importance of Wine Cellar Humidity.

Integrated Humidifier

The Wine Guardian Integrated Humidifier attaches directly to compatible Wine Guardian cooling systems and uses the same remote interface controller.

Freestanding Humidifier

The Wine Guardian Freestanding Humidifier is installed inside the wine cellar and helps maintain appropriate humidity levels for proper wine storage.

Available Upgrade Options

Wine Guardian systems may be configured with accessories and performance options depending on the cellar environment, serving-temperature needs, and climate conditions.

D050 Standard Replacement

If you need a comparable 60 Hz ducted system, the Wine Guardian D050 Ducted Wine Cellar Cooling Unit - 60 Hz is the standard ducted replacement option for many North and South American applications.

All Wine Temperatures

The All Wine Temperatures option supports a broader temperature range from 45°F (7°C) to 64°F (18°C), making it useful for cellars requiring serving-temperature flexibility.

Extreme Climate Protection

Extreme Climate Protection helps protect wine cellars exposed to low ambient temperatures below 40°F and elevated ambient conditions from 100°F to 120°F.

Ultimate Bundle

The Ultimate Bundle combines All Wine Temperatures and Extreme Climate Protection for projects requiring the widest operating flexibility.

WCE Expert Recommendation

The Wine Guardian WG75WC is best suited for wine cellar projects where traditional air-cooled heat rejection is difficult or undesirable. We most often recommend water-cooled ducted systems for luxury residential wine cellars, restaurant wine rooms, hospitality venues, geothermal installations, and projects where equipment noise and heat management are major design concerns.

Because this model has been discontinued, most buyers should consider a current replacement such as the Wine Guardian D050WC Ducted Water Cooled Wine Cooling Unit - 60 Hz. If your project does not have access to a reliable year-round water source, an air-cooled ducted wine cellar cooling system may be a more practical choice.
