The Wine Guardian cooling unit is a professional, USA manufacturered, self-contained climate control unit designed specifically for the storage of wine at cellar temperatures. It is designed for easy installation and operation. Wine Guardian uses digital electronic controls and environmentally friendly R-134a refrigerant. The entire unit is run tested at the factory and shipped as a single package. All components are of a high quality standard commercial grade. The entire unit is approved by ETL according to UL 1995 and CSA safety standards. All wiring complies with NEC. Each unit is furnished with a sealed, UL approved power cord and plug.

The Wine Guardian unit is completely self-contained and includes an integral air cooled condenser. The unit is functionally divided into two sections, the evaporator or cooling section and the condenser or heat rejection section. Each section contains a coil to add or remove heat and a fan to move the air through the coil and into or out of the cellar or adjacent space. The Wine Guardian unit is designed to be used either as a free blowing, through the wall unit or as a remote mount unit with external ductwork connections.

Air from the cellar first enters a filter to remove any airborne dust particles and then enters the cooling coil. Air passes through the cooling coil and is cooled by the refrigerant inside the coil. This causes any excess humidity in the air to condense and be captured in the drain pan and piped outside the unit. Air then enters the fan where it is pressurized and discharged out of the unit. Operational heating coils are located between the cooling coil and the fan. These coils heat the air to prevent low temperatures in the cellar. The thermostat, located in the cellar, turns on the cooling or heating as needed to maintain its set point. It does not allow the cooling and heating to be on the same time.

The compressor and condenser sections are activated whenever the unit is cooling. The condenser fan draws air from the surrounding or ambient space either directly or through a duct. The air is first drawn through a filter to remove any airborne dust particles to keep the coil clean. Then the air flows through the condenser coil where it absorbs heat from the refrigerant in the coil. The air is finally discharged out of the unit by the condenser fan.

• Cabinet - The cabinet and access doors are constructed of aluminum with a powder coated finish for corrosion protection and an attractive, maintenance free appearance. Areas in contact with cold temperatures are lined with insulation to prevent condensation
• Condensing Section - Ambient air is circulated through the condenser section by a direct drive, permanently lubricated, motorized impeller blower. This section also contains the compressor and the electrical controls. If the water cooled option is purchased, a heat exchanger is used in place of the condenser coil and blower
• Evaporator Section - Cellar air circulated through the evaporator section by another blower the same as above. The large evaporator coil face area elminates condensate carry-over, reduces air pressure drop and optimizes heat transfer. A drain pan is located directly below the coil to capture condensate is fabricated from aluminum to prevent rust and corosion. The electric heating coil, if ordered, is factory installed between the evaporator coil and the blower, and is complete with contractor(s) and limit conrol.
• Electrical Controls - Most of the electrical components and controls are located in a separate area accessible through the condenser section. All wiring is in accordance with the National Electrical Code. Wires are numbered and color coded to match the wiring diagrams.
• Factory Tested - All Wine Guardian units are factory run-tested and checked for operational performance.
• Filters - Nominal 1" thick filters are provided on both the evaporator and condenser inlets to protect the coils from dust and dirt. These filters are washable and reusable.
• Humidity Option - The optional humidifier comes fully assembled and tested for field installation onto the Wine Guardian without any additional electrical power wiring. It automatically adds moisture into the cellar by the evaporation of water over a distribution pad. A cellar mounted digital electronic humidistat automatically controls the amount of moisture added.
• Interal Drain Trap - Water condensate from the evaporator coil fills the trap and forms a seal to prevent air from being drawn back through the drain tube. This allows the drain pan to drain freely. No external trap ix required.
• Refrigerant Circuit - The factory charged circuit includes a thermal expansion valve with an external eqaulizer, slight glass with moisture indicator, a filter dryer, an automatic low pressure switch, and a manually reset high pressure switch. For the low ambient option, an automatic pressure switch controls the operation of the condenser blower and a heating element is added to the compressor oil reservoir.
• Supply / Return Grilles - Powder-coated steel single direction grilles are provided for the inlets to the evaporator and condenser sections. One grille is provided on an outlet. These are readily interchangeable with access doors to control and direct the airflow. These grilles many be used in the room on the end of the ducts in the ducted systems.

What are the advantages of external ducting?

• Lower sound levels
• Virtually no vibration in the cellar
• Better air distribution and temperature control
• Flexibility of where to locate the unit
• Ability to exhaust the excess heat and/or recapture and redirect for energy conservation
• Greater flexibility in cellar design
• Easier to service

All aluminum frame and external construction , powder coated

• Prevents corrosion and rust

Powerful motorized impeller fans

• Greater pressure capacity for external ducts on both cooling and heat exhaust sides
• Higher airflow capacities improves humidification and temperature control (more air changes per hour) and results in better temperature distribution throughout the cellar.

Filters on both coils

• Protects coils from dust and dirt, reduces costly maintenance and improves performance

Greater installation flexibility and ease at lower installed cost
