D088 – 1 Ton Water-Cooled System

The D088 1 Ton Water-Cooled cooling system is physically the same size as the Air-Cooled model but requires no airflow across its condenser. Water-cooled units are ideal for most high-rise apartment complex applications where most have chiller or cooling towers as part of the building mechanical system.

3 Year Compressor Warranty

Air Innovations shall provide a three (3) year extended warranty (5 years total) on the Wine Guardian compressor ONLY. Warranty covers the cost of a new replacement compressor should the “born with” Wine Guardian compressor be deemed defective anytime during the three (3) year extension. Warranty covers the cost of a new compressor, which must be supplied by Air Innovations. All shipping and labor charges for replacement of the new compressor are not covered under this extended warranty. The Wine Guardian “born with” compressor must be returned to Air Innovations as proof of compressor replacement. Effective date for any extended warranty is the original invoice date for the Wine Guardian unit, not the purchase date of the extended warranty.

Low Ambient Temperature Protection

Integral compressor crankcase heater to protect against low temperatures. Built-in low ambient refrigerant control valves to control condenser operation. Required when Wine Guardian is mounted in an area where temperatures fall below 40 Degrees Fahrenheit.

Integrated Electric Heater


Built-in electric heater coil and controls allow you to protect your wine cellar from low ambient temperatures. If the wine cellar falls below the desired temperature set on the thermostat, a heater will turn on to protect your wine from low temperature condition. The Electric Heater option is ideal for areas where ambient temperatures fall below 50 degrees Fahrenheit. The heating is integrated into the cooling unit and works off the same thermostat. This prevents any overlap where a free-standing heater might be on at the same time the cooling unit is cooling. Again, with the cellar thermostat controlling both heating and cooling, the wine liquid temperature will remain constant throughout the year.

Integrated Humidification System


This drip pad type humidifier is designed to be installed directly to your Wine Guardian cooling system. The humidifier comes with it's own cellar mounted humidistat for precise control of the relative humidity of your room.

Installs with the simple removal of 2 side panels on either side of the unit. Requires a water line (1/4″ hose) and a drain line (1/2″ hose) for operation. Unit features a removable drip pad for easy maintenance

Supply and Return Ducting Kits


The Wine Guardian Ducting Kits Include 2 duct collars (one supply, one return), 25 ft. of flexible insulated ductwork, and 4 tie wraps & fasteners.

The Duct Collars are molded from a lightweight plastic and provide a rigid connection to the ductwork. Available for supply and return opening with flexibility for any inlet/outlet location. Designed to be used with Wine Guardian grilles for for connections at the wine cellar.
