What This Cooling Unit Is
The Wine Guardian Defender WGTTW04B is a self-contained wine cellar cooling system installed directly through an interior wall. This design allows the unit to pull warm air from the cellar, cool it, and return conditioned air back into the space without requiring ductwork or remote condensers.
Through-the-wall systems are commonly used in small to medium residential wine cellars where a split system or ducted cooling system is unnecessary.
Who This Cooling System Is Best For
The Defender WGTTW04B works best for:
- residential wine cellars up to 600 cubic feet
- wine cabinets or enclosed wine displays
- small wine rooms or wine walls
- homeowners looking for DIY installation
- spaces where ducted or split cooling systems are not practical
When This Unit May Not Be Ideal
This cooling system may not be suitable for:
- wine cellars larger than 600 cubic feet
- large glass wine walls with significant heat gain
- commercial wine storage facilities
- cellars without proper insulation and vapor barriers
Proper cellar construction is essential to maintain consistent wine storage conditions.
Key Features
Reliable Cooling Performance
The Defender WGTTW04B delivers up to 3,760 BTU/h of cooling capacity, providing stable temperature control in wine cellars up to approximately 600 cubic feet.
This capacity allows the unit to maintain the recommended wine storage temperature of 55°F under standard conditions.
Precise Temperature and Humidity Control
Wine storage requires stable environmental conditions. The Defender system maintains cellar temperatures between 42°F and 75°F and can support humidity levels between 55% and 65% relative humidity when connected to a compatible humidifier.
A built-in thermostat and humidistat allow easy integration with humidification systems.
Quiet Operation
Wine Guardian designed the Defender series to operate quietly with minimal vibration.
Typical sound levels are approximately 56.9 dBA, making the system suitable for wine rooms located near living areas.
An optional Ultra Quiet Package further reduces operational noise.
Smart Connectivity
The Defender series includes advanced connectivity features for convenient system monitoring.
Smart control capabilities include:
- Bluetooth connectivity
- NFC system access
- Wi-Fi monitoring capability (future support)
These features allow homeowners and installers to monitor system performance and cellar conditions more easily.
Built-In Safety Protections
Wine Guardian systems include fail-safe protection mechanisms that monitor system performance and help prevent damage to the unit or cellar environment.
Safety features include:
- system monitoring sensors
- automated protective shutdown features
- protection against extreme operating conditions
Condensate Evaporator
The Defender system uses a condensate re-evaporation system, which eliminates the need for a traditional drain line.
Moisture generated during cooling is automatically evaporated by the system, simplifying installation and maintenance.
Eco-Friendly Refrigerant
The Defender series uses refrigerant designed to meet modern environmental standards, helping reduce global warming potential while maintaining high cooling efficiency.
Cooling Capacity and Cellar Sizing
Choosing the correct cooling unit depends on cellar size, insulation quality, and heat load conditions.
| Model | Cooling Capacity | Recommended Cellar Size |
|---|---|---|
| WGTTW01 | Up to 1,650 BTU/h | Up to ~250 cu. ft. |
| WGTTW02 | Up to 2,650 BTU/h | Up to ~400 cu. ft. |
| WGTTW04B | Up to 3,760 BTU/h | Up to ~600 cu. ft. |
Actual cooling performance depends on:
- cellar insulation quality
- vapor barrier installation
- glass surfaces and lighting
- ambient room temperature
For optimal performance, a heat load calculation is recommended before selecting a cooling system.
Installation Overview
The Defender WGTTW04B is designed for interior through-the-wall installation.
Typical installation steps include:
- Cutting an appropriately sized wall opening
- Installing the wall sleeve or mounting bracket
- Sliding the cooling unit into the wall opening
- Connecting electrical power
Because the system is self-contained, installation does not require refrigerant line sets or remote condensers.
Important:
The Defender unit is intended for interior wall installation only unless used with an approved exterior wall package.
