For extended wine-cellar temperature ranges. Allows a Wine Guardian unit to control 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.


For Self-Contained Ducted systems: Contains an integral compressor crankcase heater and controls to protect the system against low temperatures (required when intel 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 is 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.


Contains all the features in the All Wine Temperatures Bundle and the Extreme Climate Protection Bundle.


Includes a factory-configured integral water-cooled condensing coil and water-regulating valve. This wine cellar cooling system is ideal for geothermal, cooling tower, and lake water applications. The unit does not require warm condenser air connections, making it an excellent solution when warm-condenser-air venting is not possible.


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.


The Freestanding Humidifier is installed inside your wine space to provide optimal humidity for perfect long-term wine storage. The Humidifier can be controlled by your existing Wine Guardian controller.
