Description
Quiet, Ducted Cooling for Small to Mid-Sized Wine Cellars
The Pantheaire APEX 3500 is a ducted, self-contained wine cellar cooling system engineered for quiet operation, low vibration, and consistent temperature control in properly insulated residential wine cellars. It is specifically designed for wine rooms up to 900 cubic feet when built with R20 insulation, making it a strong solution for collectors focused on long-term wine storage rather than rapid cooling.
Unlike through-the-wall units, the APEX 3500 allows both supply and return air to be ducted away from the wine cellar, keeping heat, mechanical noise, and equipment out of view. This makes it especially well suited for display cellars, living-space-adjacent installations, and custom wine room designs where aesthetics and acoustics matter.
Is the APEX 3500 Right for Your Wine Cellar?
Well-suited for:
- Residential wine cellars up to 900 cu. ft. with R20 insulation
- Cellars built for long-term wine aging
- Projects requiring quiet, low-vibration operation
- Installations where cooling equipment must be hidden or remote
- Custom or professionally designed wine rooms
Not recommended for:
- Poorly insulated or unfinished spaces
- Glass-heavy wine rooms without proper thermal control
- High-heat commercial environments
- DIY or plug-and-play installations
- Cellars exceeding recommended capacity
If you’re unsure whether your cellar meets these requirements, our specialists provide free cooling system sizing and layout review before purchase.
Key Features & Why They Matter
Fully Ducted Design
Both the supply and return air are ducted outside the wine cellar, preventing heat buildup, fan noise, and vibration inside the space where wine is stored.
Self-Contained Cooling System
All mechanical components are housed in a single unit, eliminating the complexity of split systems while maintaining efficient, controlled operation.
Low-Vibration Performance
Designed to minimize disturbance to sediment-sensitive wines, supporting proper aging conditions over time.
Two-Speed Fan Operation
Provides airflow flexibility to maintain stable temperatures under varying load conditions:
- Speed 1: 260 CFM
- Speed 2: 290 CFM
Digital Temperature Control
Allows precise management within the ideal wine storage temperature range when paired with proper insulation and vapor barriers.
Installation & Planning Considerations (Important)
The Pantheaire APEX 3500 is not a plug-and-play appliance. Proper planning and installation are critical to performance and system longevity:
- Ducted installation is required
- Cellar must have R20 insulation and a continuous vapor barrier
- 8" supply and 8" return ducts are required
- Maximum duct length is 25 feet per duct run
- Condensate drainage must be planned using the 5/8" ID drain connection
- Professional installation is strongly recommended
Improper insulation, vapor barrier failures, or poor duct design will negatively impact cooling performance and may shorten system lifespan.

📚 Frequently Asked Questions (FAQs)
The APEX 3500 is designed for wine cellars up to 900 cubic feet, assuming the space is built with R20 insulation and a proper vapor barrier. Larger or poorly insulated spaces will require a higher-capacity system.
No. The APEX 3500 is a self-contained ducted system, meaning all mechanical components are housed in one unit. It does not require a separate outdoor condenser like a split system.
Yes. Ducting is required. Both supply and return air must be ducted using 8\" ducts, with a maximum duct length of 25 feet per run.
Professional installation is strongly recommended. Proper duct design, insulation, vapor barrier installation, and condensate drainage are critical to system performance and longevity.
Because the system is fully ducted, fan noise and mechanical vibration are kept outside the wine cellar, making it a good option for installations near living spaces or display areas.
The system is designed to operate within a 50–70°F (10–25°C) range. For long-term wine storage, most collectors target temperatures around 55°F.
Without proper insulation or a vapor barrier, the system may struggle to maintain temperature, run excessively, and experience premature wear. We recommend addressing insulation issues before installing any cooling system.
The system helps manage humidity as part of normal cooling operation, but it is not a dedicated humidity control system. Proper cellar construction plays the largest role in humidity stability.
The system includes a 2-year manufacturer warranty covering parts and labor, provided installation and operating conditions meet manufacturer guidelines.
