Panthaire Wine Cellar Cooling Systems APEX 3500

Quiet, Ducted Cooling for Properly Insulated Residential Wine Cellars The Panthaire APEX 3500 is a fully ducted wine cellar cooling system designed to deliver stable, low-vibration temperature control for small to mid-sized residential wine cellars. Engineered for collectors who prioritize consistent aging conditions and discreet operation, the APEX 3500 offers dependable performance without the complexity or cost of split systems. When installed in a properly insulated cellar up to 900 cubic feet, this system maintains ideal wine storage temperatures while keeping mechanical noise and airflow outside the cellar. Who the APEX 3500 Is Best For The APEX 3500 is an excellent choice if your project includes: A well-insulated wine cellar (R20 insulation assumed) Cellar volume up to approximately 900 cu. ft. A ducted installation to isolate sound and airflow Residential collections focused on long-term wine aging Cellars located near living spaces where quiet operation matters This system is commonly used in: Custom wine rooms Basement and closet wine cellars Projects where equipment must remain hidden from view When to Consider a Larger or Different System You should consider upgrading to a higher-capacity unit or split system if: Your cellar includes large glass walls or glass doors Insulation levels are below R20 The cellar exceeds 900 cu. ft. You are building in hot or highly variable climates Duct runs exceed recommended lengths or layouts In these cases, a larger APEX model or a split cooling system may provide better long-term stability and efficiency. Designed for Stable Wine Aging Wine ages best in a narrow, stable temperature range, typically around 55°F. The APEX 3500 is engineered to maintain this consistency while minimizing vibration, airflow disruption, and temperature swings that can negatively affect aging wine. Key Performance Advantages Fully ducted design keeps noise and airflow out of the cellar Low-vibration operation helps preserve sediment integrity Two-speed airflow control balances cooling efficiency and sound levels Digital temperature control for precise setpoint management Quiet operation ideal for residential environments By separating mechanical operation from the cellar space, the APEX 3500 supports a calm, controlled environment suitable for long-term wine storage. Installation & Design Considerations The APEX 3500 is designed for ducted installations and performs best when cellar construction follows wine-storage best practices. Important Installation Notes Requires 8″ supply and return ducting Maximum duct length: 25 ft per duct Electrical requirement: 115V / 60Hz / 15A Drain connection required for condensate management Vapor barrier and insulation quality directly affect performance Expert Note: Cellar size ratings assume proper insulation, airtight construction, and minimal glass exposure. Inadequate insulation or high ambient heat loads may reduce effective cooling capacity.
