Overview
Koolatron's WC18DZ holds 18 bottles across two independently controlled thermoelectric zones, in a compact 1.7 cubic foot freestanding cabinet meant for a home bar, kitchen or apartment.
The upper and lower compartments hold about 9 bottles each with independent touch screen temperature control, cooling thermoelectrically across a 46 to 66°F range. The one available review found actual temperature swings wider than expected, especially in the lower zone.
- 18 bottle capacity across two independent zones
- Touch screen temperature and light controls
- UV protective double-paned glass door
- Thermoelectric cooling from 46 to 66°F
Who it's for
A small apartment or home bar wanting a compact dual zone cooler with UV protective glass, rather than a full size wine fridge, is the target buyer. Tight, stable temperature control is not what this delivers, based on the review below.
What buyers say
From Amazon customer reviews.
The one available review reported the cooler cycling 5 to 6 degrees above and below its setpoint, with the lower zone regularly running warmer than the 65°F target set for both compartments. That buyer said the unit still kept wine from overheating in a garage during summer, but described the manufacturer's suggested return process as a hassle.
Strengths and trade-offs
Drawn from this product's published specifications.
- Independent touch screen control for two temperature zones
- UV protective double-paned glass door
- Thermoelectric cooling runs without compressor vibration
- One buyer measured 5 to 6 degree temperature swings, mainly in the lower zone
- Returning a unit was described as a hassle by that buyer
Performance notes
Thermoelectric cooling runs quietly without the vibration that can disturb sediment in compressor units, with each of the two zones independently set through touch screen controls. One buyer measured the lower zone cycling 5 to 6 degrees around its setpoint rather than holding steady.
