The Slimline LS replaces both Slimline 2500 and Slimline 3300
We are happy to announce the first unit in our new Luxury Series (LS). The new Slimline LS has evolved into a single system with a plethora of enhanced features that provide powerful performance, quiet operation, and prolonged system longevity to protect your investment in fine wine for years to come.
MAIN PRODUCT FEATURES:
TWO SPEED FAN SWITCH
The unit is now equipped with a 2-speed fan switch, which allows a low setting for quieter operation or a medium setting for maximized performance.
QUIET OPERATION
The Slimline LS boasts a new fan system that has optimized system performance, allowing the unit to operate at a significantly lower noise level.
NEW DURAMAX COILS
Our latest coil innovation maximizes performance while providing system longevity, protecting coils from formic acid, and leaks over time.
CONDENSATE MANAGEMENT
Our new, efficient condensate management system evaporates up to 3 OZ of water an hour, which renders the drain line as an additional safeguard.
INTERCHANGEABLE DECORATIVE PANEL
The system is designed to add a customizable, decorative panel, which enables customers to create a unique look above the doorway of their cellar.
CONTROLLER RELOCATION
The controller is now mounted on the condenser side of the unit, allowing the system to be monitored without disturbing the cellar's atmosphere.
WHY YOU SHOULD CHOOSE THE SLIMELINE LS:
HIGHER SYSTEM CAPACITY
Up to 45% capacity upgrade in a slightly larger package, we utilized every inch of space inside the system to deliver maximum performance. While the opening is the same, the unit is only 2 in. deeper.
EASY INSTALLATION PROCESS
The system utilizes a simple two-bracket mounting system, which holds the unit firmly in place once it is attached to the wall.
COMPLETE SYSTEM SUPPORT
All WhisperKOOL units come with the support of an in-house technical support team that's there to make sure your unit works as desired. We're here for you before, during, and after the sale of your unit.
NEW INNOVATIVE SYSTEM FEATURES:
UV Lighting System Upgrade -

Have the ability to cool two capacities at the flip of a switch. We have added larger coils and centrifugal blowers that are significantly quieter, being controlled at either the medium or low setting, and allows the system to cool cellars up to 1000 cu. ft.* (45% more capacity).

The controller has been moved to the condenser side of the unit so that it is viewable from the outside of the cellar, and the power cord and bottle probe are now located inside the cellar. We have also added a condensate evaporator to manage condensate produced by the coil.

The carbon fiber panels give your unit a luxurious aesthetic and now provides you with the option to replace the unit's carbon panel with your own custom decorative panels. This will enable you to create a truly unique and attractive look above the doorway of your cellar.

Owner Manuals & Tech Sheet
BTU/H Rating
1453
The BTU/h value shown here is a theoretical number. There are often circumstances under which a cellar design may require a larger unit due to variables not accounted for in the formula. For example, these variables could be building materials (such as glass, stone, concrete, etc.) which do not offer the insulation capacity required to maintain the optimal cellar environment. We recommend purchasing a unit with a larger capacity to compensate for these unaccounted-for variables. An undersized unit can lead to premature failure and will most likely prevent the cellar from reaching your desired temperature.

Questions, answered
Slimline LS FAQ
Straight answers from the team that sizes, installs and services wine cellar cooling every day.
Where does the Slimline LS go?
Through the wall, above a doorway. It hangs on a simple two-bracket mount. It replaces both the Slimline 2500 and the Slimline 3300: the wall opening is the same, and the unit is only 2 inches deeper.
What size cellar does it cool?
About 300 cu. ft. on the low fan setting and 650 cu. ft. on medium, in a cellar that is fully insulated and sealed with a vapor barrier. Every cellar is different, so we recommend a free heat-load calculation before you order.
How warm can the room behind it be?
The Slimline LS holds a 55°F cellar with condenser intake air up to 85°F. Venting it outdoors is not recommended. For hotter spaces, look at the Extreme series.
Do I need a drain line?
Its condensate system evaporates up to 3 oz of water an hour, so the drain line works as a backup safeguard. Connect a 1/2" ID clear plastic drain line (not included).
What power does it need?
A dedicated 115V, 20-amp circuit. A 230V version is subject to availability.
Can I change how it looks?
Yes. The carbon fiber front panel can be swapped for your own custom decorative panel, so the unit matches the space above your cellar door.
