WhisperKOOL Slimline Wine Cellar Cooling Units - Through to The Wall

The WhisperKOOL Slimline LS is a premium, self-contained, through-the-wall wine cellar cooling unit designed to utilize the space between a cellar door and the ceiling. As the direct technological upgrade for the discontinued Slimline 2500 and 3300 models, it delivers 20% more cooling capacity in a sleek, low-profile footprint.

Key Specifications & Performance
  - Cooling Capacity: Features a customizable two-speed fan switch. It cools compact cellars up to 300 cubic feet on low speed and mid-sized rooms up to 650 cubic feet (potentially up to 1,000 cubic feet under ideal insulation) on medium speed.
  - Operating Conditions: Engineered for indoor use, it maintains a 55°F cellar temperature provided the adjacent exhaust room remains at or below 85°F.
  - Advanced Acoustic Engineering: Equipped with custom centrifugal blowers and an intelligent ECM condenser fan for whisper-quiet operation.
  - Liquid Temperature Sensing: Includes a bottle probe to monitor the actual temperature of the liquid, preventing short-cycling.

Pros & Cons
  - Pros: Excellent space optimization, ultra-quiet sound levels on low-speed mode, simple DIY installation with a single-piece mounting bracket, and an upgraded condensation management system.
  - Cons: Higher luxury price point, no support for remote or smart thermostats, and longer cooling intervals when set to low-speed.

Custom Upgrades & Add-ons
  - UV-C Lighting System: An optional integrated mechanism to prevent mold and micro-bacterial growth (requires 4 inches of additional side clearance).
  - Interchangeable Decorative Grilles: Removable faceplates to match high-end wood or modern cabinetry.
