CellarPro 1800XTSx Cooling Unit Outdoor #1652 (for cellars up to 400cuft)


SKU 1800XTSx Categories ,


1886 BTUH @ 55°F.
CellarPro’s 1800XTSx wine cooling units (1/4 Ton Nominal) were designed for outdoor installations and engineered to provide maximum cooling performance for small wine cellars up to 400 cubic feet.*

Starting with CellarPro’s 1800XTS, we’ve added the following options and upgrades:

  • An outdoor hood to protect the rear of the cooling unit from rain.
  • Rear condensate drain line to channel excess condensate away from the cooling unit.
  • Compressor heater to protect internal components from damage in cold temperatures.
  • Power cord modification to allow the unit to be powered from inside the wine cellar.
  • Coated condenser coils to protect against outdoor pollutants and extend the unit’s longevity.

Please note: the exterior hood must have at least five (5) inches of clearance on the rear side, and 18 inches of clearance below the cooling unit outside the cellar. In addition, the cooling unit requires at least eight (8) inches of clearance inside the cellar in front of the cooling unit (same as other 1800 cooling units.)
