The WGS40 is a ducted split wine conditioner ideal for small residential & commercial wine rooms.  Use our innovative wine cooling calculator to determine if this wine cooling unit will be suitable for your wine storage space. The WGS40 wine conditioner is a step up from the WG25. If the cellar is sized for the WG25 and contains a lot of glass, we recommend moving up to the WGS40. Low ambient protection is standard and features a control system that protects the wine conditioner from cold temperatures below 16°C (60°F).

[The WGS40 is a 50Hz system, which is standard in the majority of Europe, Asia, Africa, & Australia; if you need a comparable 60Hz system (used in most of North and South America) see the DS025 wine cellar cooling unit. Verify your country’s line frequency.]

The WGS40 wine cellar air conditioner can be purchased in a standard configuration or with many options and accessories, shown below. The Extreme Climate Protection bundle protects the condensing unit in extreme climate conditions. The All Wine Temperatures bundle contains both a factory-mounted heater to protect your cellar from low room temperatures and extended controls to adjust your wine room or wine display to serving temperatures.

Condensing unit is patented. US Patent No. D791295. EU Patent No. 003189349-0001. UK Patent No. 9003189349000

Where to Buy


Standard Options

Low Ambient Protection

Protects the system from cold temperatures below 5°C (40°F).

Available Options

All Wine Temperatures Bundle

For extended wine-cellar temperature ranges. Allows a Wine Guardian unit to control to an extended temperature range from 45°F(7° C) to 64°F(18° C), perfect for single to multiple cabinet applications and small wine rooms in which serving-temperature cooling is preferred.

This bundle also contains an integral electric heater coil and controls to protect wine cellars from dangerously low temperatures. It is ideal for areas where ambient temperatures fall below 50°F/10°C.

Extreme Climate Protection Bundle

For Self-Contained Ducted systems: Contains an integral compressor crankcase heater and controls to protect the system against low temperatures (required when inlet air to the condenser coil is below 40°F/5°C). The bundle also contains an integral high capacity condenser fan and coil for operation at elevated ambient temperatures. This bundle should be considered when inlet air to the condenser coil is above 100°F/38°C (condenser air inlet cannot exceed 120°F/49°C).

For Ducted Split systems: Unit protection in extreme climate conditions (on the condenser section only). It is required for continuous operation in climates that fall below 20°F. Enables the system to operate in temperatures as low as -20°F.

Integrated Humidifier

Humidifiers help ensure perfect long-term wine storage conditions by adding humidity back into your wine space. The Integrated Humidifier attaches directly to your Wine Guardian cooling system using the same power source and remote controller.
