Designed for 800–2,000 cubic feet (model dependent)
Operates in exhaust environments up to 110°F

Who This System Is Designed For
Best For:
Fully insulated residential wine cellars
Warm garage or mechanical room installations
Cellars between 800 and 2,000 cu. ft.
Homeowners who want temperature monitoring outside the cellar
Installations where split systems are not practical
Who Should Not Use This System
This system is not recommended for:
Unsealed basements or unfinished rooms
Glass-heavy cellars without professional heat load calculation
Cellars larger than 2,000 cu. ft.

If your project exceeds these constraints, a split system may be more appropriate.
