October 2021 - Currently Sentinel Series is available on just the ¼ Ton Units – eventually the Sentinel will be available on other units. 

“Wine Guardian’s Sentinel Series units are the strongest and most energy-efficient wine cellar cooling systems on the market. They provide optimal temperature and humidity control with a design that allows for easy installation and service. Some key features on the new Sentinel series units include:

  1. Efficient & Insulated  : The Sentinel Series body features up to three times more insulation than previous versions.   The stronger, double walled duct collars have also been redesigned with more insulation; this will help maintain cellar temperature and reduce condensation.   
  2. Comprehensive Read Outs:  Up to 3 optional remote sensors to provide extended range of temperature and humidity control.    2 remote interface controllers to monitor and control cellar from whatever room you are in.
  3. Stronger Shell: The casing for the Sentinel Series is five times stronger than the previous, features an all-aluminum chassis, and contains coated coils to ensure product durability.
  4. Accessible for Service: The multi-panel design, allows for ease of access for servicing.
