Description
APEX 3500
Fully ducted cooling for smaller rooms.
APEX 3500 keeps well‑insulated cellars up to about 900 cu ft.
Remote ducting removes equipment noise from the room.
Digital controls and adaptive airflow maintain a steady set point, and a 2‑year parts and labor warranty supports long‑term reliability.
Wall Openings
- Two 6″ x 12″ wall openings are installed on opposite sides of the cellar to generate effective cross-flow:
- Supply Air: High on the wall
- Return Air: Low on the wall
Mechanical Room Access
- Adequate space nearby to house the cooling unit
- Ventilation in the room is sufficient to dissipate heat
Ductwork Requirements
- Ducts (e.g., 8″ supply and 8″ return) are planned with:
- Maximum of 25 feet per duct (50 feet total combined)
- Smooth, gradual bends (avoid sharp turns)
- Ducts will be insulated to prevent condensation and minimize noise
2 Electrical & Drainage
Dedicated Electrical Circuit
- A dedicated circuit is available for the unit:
- Typically 115V/20A (or 120V/15A, based on your specific unit requirements)
Drain Access
- A drain is located within 15 inches of the unit, or a condensate pump is planned if farther away
- Ensure proper drain line installation with a slight slope and no blockages
3 Cellar Construction & Insulation
Insulation Standards
- Walls: Minimum R20 insulation
- Ceiling: R20–R30 insulation
- Floor: Minimum R20 insulation (if the cellar isn’t in a basement)
Vapor Barrier
- A vapor barrier is installed on the warm side of the walls/ceiling
Floor & Door Considerations
- There are no heated floors, or a 12-inch gap is maintained if present
- The cellar door has proper seals; note that glass doors may need additional insulation
4 Ambient Conditions
Mechanical Room Temperature
- The room housing the unit maintains an ambient temperature between 50°F and 77°F (10°C to 25°C)
Humidity Control
- The cellar area is not prone to high humidity, reducing the risk of mold and system strain
5 Installation Preparation
Unit Handling
- The cooling unit must be kept in an upright position, with the compressor at the bottom, for at least 24 hours before installation
3353 BTU/h
Recommended for rooms up to about 900 cu ft. Final sizing depends on insulation level, glass percentage, and ambient temperature. Let us Calculate your BTU requirements. Click Here to Contact Us.
Ideal For
- Small private cellars, glass wine walls, compact displays, and retrofits that need quiet, concealed cooling.
Design Highlights
- Concealed fully ducted install.
- Digital thermostat with stable control.
- Low vibration to protect aging.
- Accessible panels and standard fittings for faster service.
Considerations
- Glass and warm ambient increase heat load. If more than half the enclosure is glass or the space runs warm, add capacity margin or move to APEX 5000.
