CellarPro’s 4200VSi cooling units (1/2 Ton Nominal) are suitable for wine cellars up to 1,000 cubic feet in both commercial and residential wine cellars. The 1,000 cubic feet cellar size assumes that the cellar is constructed with insulation of R19 or better in all walls and ceiling (ie no glass or uninsulated concrete), the cooling unit is not ducted, a setpoint of 55°F inside the cellar and ambient temperatures up to 85°F outside the cellar.

Performance testing shows that this unit maintains optimal cellar temperature and humidity conditions in extreme conditions up to 115°F more effectively than similar units from competing brands. 4200VSi units also are significantly quieter than comparable units from other brands.
