The WhisperKOOL XLT Series consists of 5 well built and highly reliable wine cellar coolers that mount through-the-wall, blowing cold air into your wine cellar and hot exhaust air into the adjacent room. To ensure that your WhisperKOOL XLT will operate correctly and for many years, there are a few things you must consider regarding venting the unit that will be detailed below, but first we’ll briefly recap things to be aware of when selecting a WhisperKOOL.
The wine refrigeration units in the XLT Series that I am referring to are:
- WhisperKOOL XLT 1600
- WhisperKOOL XLT 3000
- WhisperKOOL XLT 4200
- WhisperKOOL XLT 6000
- WhisperKOOL XLT 8000
They range from 1600 BTUs to 8000 BTUs. The maximum size of a wine cellar the WhisperKOOL XLT 1600 can cool to 55°F is 300 cubic feet and the WhisperKOOL XLT 8000 model can cool up to 2000 cubic feet. However, you cannot simply invest in a wine cooling unit based on cubic footage alone….The best WhisperKOOL XLT cooler for you room is also dependent on a few other things, including:
- temperature of the intake air in the “venting room” or outside (if you are venting to the outdoors)
- proper insulation (walls, ceiling and maybe floor depending on where it is located geographically and in the building)
- amount of glass in doors or windows
- type of glass (single, double or triple pane)
- heat gain from lights or how often the door is opened and closed
- how well the door and room are sealed with a door sweep and weather striping and vapor barrier
Give a ring or email or post on the blog if you would like advice on deciding what XLT model is the most appropriate one for you, taking into consideration all the factors when building a wine room…
Also, use our BTU calculator!
WhisperKOOL XLT exhaust is about 90°F. That’s HOT. So, we have to make sure that this hot air is not going to be detrimental to other parts of your home, restaurant or wine shop, or be sucked back into the cooler through the intake fans located just below the exhaust fans. These cooling systems only have a 30°F differential/delta between the intake air and the temperature it can achieve in the wine room. If the thermostat is set for 55°F, then the maximum temperature of intake air can be 85°F. From our years of experience thought, it is probably better to be within 25°F.
Adjacent room should be 2 times larger than the wine cellar if you are not planning on removing the hot exhausting the hot air from the cooler out of the room.
If the adjacent room is smaller than 2 times the size of the wine cellar, it’s a good idea to have a fresh air vent to the room and/or an exhaust vent.
WhisperKOOL offers an Exhaust Ducting Kit. This is good for when the temp of
Intake fans are not strong enough to hook up ducts to in order to pull fresh air to the unit.
Outside…not good idea. too cold and too hot sometimes. If you do, must use the WhisperKOOL XLT Exterior Grille.

Keep in mind that the entire point of getting a cooler is to protect your wine. The WhisperKOOL XLT is a fantastic through-wall unit, that is economical, but built much better than most other coolers in its class. However, if you simply cannot vent it properly and the install is not ideal for it to work effectively and efficiently, please do yourself a favor and consider a Split System or WhisperKOOL Extreme. One time we had a Split System in a client’s garage, ready to install in a day or so, but he decided to save money and had us put in WhisperKOOL XLT instead. The wine cellar was in a finished basement in about an 8000 sq. ft. luxury home in New England. He is a wealthy man so not having money was not the problem, but for some reason he just wanted to save money against our recommendations to use a split system. Sure enough, a few months later, he told me that the heat blowing into the extra bedroom was way too hot and he is not pleased with the noise.
