WhisperKOOL Slimline LS: Ultra-Compact Wine Cellar Climate Control
Looking for a space-saving wine cooling solution that doesn’t compromise on performance or style? The WhisperKOOL Through The Wall Slimline LS delivers exactly that: an elegantly designed, high-performance unit engineered for modern collectors with limited wall space.
With its customizable front panel, the unit's exterior can be finished to match the surrounding cellar wall. The upgraded two-speed fan switch boosts capacity by 45%, delivering the cooling power needed to keep your collection perfectly preserved, regardless of outside conditions.
Designed to mount above a door, this innovative unit utilizes space that often goes unused, freeing up valuable cellar real estate without sacrificing cooling coverage. Meanwhile, the liquid-temperature-sensing bottle probe and built-in condensate evaporator maintain precise conditions for optimal aging.
The Slimline LS also features an optional UV-C Lighting System, helping shield your wine from invisible microbial threats that could compromise flavor and aroma. Paired with energy-efficient operation and a sleek electronic display, this unit offers total control with minimal intrusion. Sound level: WhisperKOOL does not publish a decibel rating for the Slimline line. Ask us and we will put the question to the manufacturer in writing.
BTU/h value range: 1704 – 2413
