Optional Integrated Humidifier 

 

General Description 

The humidifier is designed to increase the cellar humidity level above a 50% threshold where 
wine bottle storage is more stable for preserving the corks. It is intended for situations where 
the  ambient  relative  humidity  of  the  air  surrounding  the  cellar  is  insufficient  to  maintain  the 
desired humidity level inside the cellar, as indicated by the shaded areas in the chart below:

The humidifier is controlled by a 24V remote humidistat powered from the cooling unit.  The 
humidistat must be mounted inside the cellar near the return air plenum inside the cellar.  The 
humidifier operates independently from the cooling unit, and uses the cooling unit evaporator 
fan  to  circulate  the  air.    The factory  set-point  on the  humidistat  is 55%RH,  adjustable  in  5% 
increments to a maximum of 70%RH.
