CASO Design WineDeluxe WDU 18 slimline built-in wine cooler: just 30 cm wide, 18 bottles, two temperature zones from 5 to 20 °C with cascade control, handleless push-to-open door, triple-layer insulating glass with UV filter, activated carbon filter and control through the CASO Control app.
Only 30 cm wide: the CASO Design WineDeluxe WDU 18
The CASO Design WineDeluxe WDU 18 solves a very specific problem: kitchens where every centimetre counts. At 29.5 cm wide it fits a narrow niche and still holds 18 bottles across two temperature zones. The black glass front, handleless push-to-open door control and Soft-close hinges keep the cabinetry line clean, while adjustable installation height and a removable plinth make fitting the niche straightforward.
Two zones from 5 to 20 °C with cascade control
The appliance offers two temperature zones, electronically adjustable from 5 to 20 °C. They work with cascade control: the upper zone must be the same temperature as the lower one or colder. In addition, the temperature reachable inside cannot be above the ambient temperature at the installation site. Both points are worth allowing for when planning storage.
Interior and storage conditions
It takes bottles up to 76 mm in diameter on four wooden shelves that make removal easy without damaging labels. Active ventilation spreads the cold evenly, the triple-layer insulating glass with UV filter shields the aromas from light, and the activated carbon filter keeps interior air quality stable. A door alarm reports a door left open.
Ambient light and the CASO Control app
The white ambient LED strips along the sides are switchable across four levels (25%, 50%, 75%, 100%). The built-in Wi-Fi module connects the appliance to the free CASO Control app (iOS and Android) for temperature control, lighting control and notifications if a fault occurs.
