Seven cooling decisions you make once, before construction. Each is a chapter, with links to the full articles when you want more detail. Free, in your inbox within two minutes.
Inside the guide
The target temperature
Wine stores best at 55°F, inside a 50–70°F range. A stable ±4°F band protects wine better than chasing an exact number.
Sizing the unit
Cooling load is calculated by cubic footage and insulation grade. Glazed cellars add roughly 15% to the load. APEX covers cellars up to 900, 1,200, and 2,000 cubic feet across three models.
The cellar envelope
A wine cellar needs R-20 insulation and a vapor barrier on the warm side of the wall. Most cellars that fail to hold temperature trace back to envelope mistakes, not the cooling unit.
Where the unit goes
The air around the condenser must stay between 50°F and 77°F. Garages, attics, and uninsulated crawlspaces fall outside this range and compromise performance.
Mounting and ducting
APEX is a single ducted, self-contained architecture with three mounting positions: floor, wall, or ceiling. An intake-duct option handles installations where heat can accumulate.
Long-term operation
APEX runs on R290 refrigerant with a scheduled defrost cycle and a wired control panel. The carbon filter is replaced yearly.
Who installs it
APEX requires a licensed HVAC professional. DIY installation voids the warranty. The guide includes five questions to vet an installer in 90 seconds.
Who builds APEX
One team, start to finish.
The people who engineer APEX are the same people who ship it and answer the phone when you call.
