This system is designed to maintain 55°F in a cellar up to 1000 cubic feet in size. 

System Features:

NewBTUh Rating:
There are circumstances in which a cellar design may require a larger unit due to existing restrictions. Building materials such as glass, stone, concrete, etc. do not offer the insulation capacity required to maintain the optimal cellar environment. We recommend purchasing a unit with a larger capacity to compensate for design limitations. * Please utilize our Cellar Wizard in order to ensure you are selecting the proper cooling unit for your application. Undersized cooling units can lead to premature failure and/or prevent the system from reaching the desired set temperature. As a result, they are not covered under warranty.

  • 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.

  1. Upgraded from 3000XLT 4 Star Review

    Posted by on Apr 9th 2013

    I've had a custom walk in cellar cooled by a Vinotheque 3000 XLT unit for over 10 years. While I was always happy with the unit it did run quite a bit and, as a result, I had to replace it every few years. To their credit, Vinotheque offered a reasonably priced "trade-in" program and was always quite prompt in sending the new unit. The last time I contacted them they offered the substantially more expensive new Extreme series unit which they said would fit right into the existing hole. I decided to switch and I'm extremely happy I did.

    While the 3000 XLT was a substantial unit, from the moment I opened it I could easily see that the Extreme took things to another level. It is much quieter, moves far more air and, as a result, runs far less often. Vinotheque asked me to send in picture of my installation and made some recommendations and offered to extend the warranty to four years if I made them.

    I wanted to remodel and expand the cellar anyway so I did that an incorporated all their suggestions. I'm thrilled with the results, the Extreme runs even less often (mostly, I think, because I super-insulated the door -- something I would recommend to others because it makes a huge difference). Vinotheque was as good as their word and promptly extended the warranty once I sent in new photos.

    No product, no matter how good, is any better than the service that backs it up. I've read all sorts of horror stories about poor service
    for wine cellar cooling units. My recommendation is to look no further than Vinotheque -- great cooling units and even better customer service.

  2. Works fabulously! 5 Star Review

    Posted by on Dec 6th 2012

    I recenly replaced my old WK4200 XLT with the Extreme 5000ti. My cellar is well insulated and holds 1200 bottles. Upon start up, the temperature was 68 degrees and less than 48 hours it reached set point of 55 degrees. I am truly impressed and pleased that I was talked into upgrading to this machine!

  3. Works Great! 5 Star Review

    Posted by on Apr 27th 2012

    I have collected about 600 bottles and the temperature is staying at 55 degrees in my garage cellar. During the summer, temperatures can reach over 100 outside, with 95% humidity. I made sure to build the cellar with good insulation and vapor barrier. The Extreme hasn’t missed a beat. I’ll let you know how it goes after another hot summer.
