The Wine Guardian SS018 is a versatile ductless split cooling system engineered for small wine cellars up to 1,200 ft³ (≈ 34 m³). Ideal for spaces where mechanical rooms or ducting aren’t feasible, it offers both through‑the‑wall and surface‑mount installation options. With cooling capacity ranging from 400–2,800 BTU/hr, it maintains storage and serving temperatures (as low as 40 °F/4 °C), and supports optional add-ons like electric heat, low‑ambient operation, and humidity control to preserve your wine collection in any environment.
