Additional Information

A Ducted Split system has more installation options than a self-contained system. The unit may be installed up to 25 ducted feet from the cellar, with the cool air flowing to the cellar and the heat exhaust ducted to the outside of the home. Ducting is also a more aesthetic choice for wine collectors who do not want to see a cooling unit in the cellar. Noise from the unit will be reduced or eliminated, depending on the installation.

Described in the simplest terms, a split system is a cooling unit wherein the evaporator unit and condensing unit have been “split” into two separate units instead of being contained within the same housing. The evaporator unit is located in or near your cellar, and the condensing unit is generally located outside, or in an attic or utility room.

The Ducted Platinum Split 4000 allows you to decide where the evaporator unit and the condensing unit will be located. The condensing unit can be located up to 100 ft. away from the evaporator unit. The evaporator unit will be mounted in the cellar or it can also be located nearby with ducting.


For the Split System series, a 24V option is also available which allows you to tie into your home electronic thermostat or home automation system, please inquire.

Although the cooling units are rated for various size rooms, the thermal load may require a larger sized cooling unit. Thermal load may be affected by glass in the cellar, room positioning or other factors. Please let a Rosehill Wine Cellar rep make some suggestions for you if needed.
