Wine Guardian cooling systems are engineered for maximum versatility, efficiency, and ease of use when it comes to storing and aging wine. Wine Guardian Pro units take this standard of excellence one step further to address the unique needs of the wholesale community. From distributors to refrigeration wholesalers to HVAC installation professionals, the Wine Guardian Pro series makes installation, customization and maintenance of our solutions—for commercial or larger residential applications—seamless.

Wine Guardian Pro specialty commercial & residential HVAC systems are the most versatile specialty cooling systems on the market. These units can be utilized in a variety of scenarios where temperature and humidity control are needed to protect valuables. In addition to wine, our specialty cooling systems preserve instruments, fur, cigars, art and documents, and even server-room equipment, from the harmful effects of heat and humidity. These units can be used in nearly any application.

The Pro Ducted systems are ideally suited to floor, ceiling, or wall applications. They are available in both water- and air-cooled options.


The Wine Guardian Pro series has a number of features that facilitate a straightforward installation. The systems are constructed of lightweight aluminum with built-in lift handles making it easier to manage and position the device.

Once the units are in place, the process of getting the systems up and running has been engineered with ease in mind. First, the multi-panel design makes it possible to custom configure the setup for a particular application through up to three ductwork connections. These ductwork connections are on both the evaporator and condenser units. Also, integral refrigerant sight glass enables a technician to determine the correct equipment charge, while charging the entire system is easily done through external refrigerant service valves.

The easy plug-and-play design with power cord is standard in all units. Moreover, the primary power, controls, drain, and water-connections are centralized for an efficient utility connection in all Wine Guardian Pro Ducted systems.


Wine Guardian Pro units utilize 24-volt electronics and are Wi-Fi compatible. These features allow for simple integration with today’s smart homes or commercial building management systems. In short, clients can manage a Wine Guardian Pro unit from their existing control system.

Additionally, while our standard units can be customized at the time of ordering with high- or low-ambient protection, the Pro series comes with these options built right in. Wholesalers working with clients across a variety of climates will appreciate having one system with this level of flexibility to meet the individual needs of their customers.

An integral electric heater is another way the Pro series can be customized depending on where a client is storing their wine or valuables. In addition, the Pro series is robust enough to accommodate the retrofitting of a humidifier should a customers’ needs change after purchase.


Wine Guardian Pro units have also been engineered to simplify routine maintenance. For instance, the systems come equipped with sight glass revealing the volume of refrigerant in the system. Technicians are able to quickly view the level of coolant, which eliminates the need for a dedicated gauge. This helps makes service far more efficient.

Maintenance is also improved through a feature that protects the units from potential mechanical glitches. Typically, if a cooling system is under- or overcharged—or experiencing a leak—it will continuously cycle on and off. However, the Wine Guardian Pro units include high- and low-pressure switches that open up and stop the system before damage can be done. In addition, the condenser air intake filter is removable and washable in all ducted systems. The multi-panel design of the fan-coil also ensures access to the fan and nearby electronics.

Lastly, two screws on the outside of the unit make it easy to access the main control panel for routine maintenance of the system.

Note: At this time, our Pro ducted units are not configured to store wine at serving temperature.
