System Features:


NewActive Humidity Option:

Our new Active Humidity feature carefully measures the volume of moisture needed to raise the relative humidity within the cellar to the desired level. This design utilizes Intermittent Mist Injection Technology which eliminates the use of pads or filters that can mold over time. Easy to install and effortless in use, simply connect a soft water source to the unit, install the humidistat and you are ready to go. This optional integrated system must be specified at the time of ordering of the unit. For cellars with cooling units already installed, customers can select our stand alone system which offers the same technology in a small, but effective, package.

Active Humidity Features:

  • Maintains optimal humidity levels when relative humidity level drops.
  • Intermittent Mist Injection Technology - No pads or filters which can mold over time.
  • Included humidistat displays and monitors humidity levels.


Option Details

  • The Exterior Grille protects the exhaust side of the system from the weather elements when installed through an exterior wall.
  • The Exhaust Plenum allows the warm exhaust air to be ducted to another area. Ideal if the room adjacent to your cellar is not ideal for warm air to be exhausted into. This also allows you to duct the condenser supply air from an alternate location.
