Self Contained Rear / Top Vent Cooling Unit 1800XT-ECX #1086
All air-cooled refrigeration equipment requires fresh air intake to dissipate the heat generated by the cooling unit. The fresh air intake CANNOT come from the wine cellar space - it must come from space outside the cellar. Designed for indoor use only, 1800XT-ECX units can operate in environments ranging from 95F to 40F out of the box. To operate the unit in colder temperatures, please see modifications listed on the Options & Upgrades tab.
CellarPro 1800XT-ECX cooling units (1/6 Ton Nominal) are suitable for small wine cellars (up to 250 cubic feet), commercial applications and wine cabinets located in garages (in temperatures ranging from 50-95F).
Performance testing shows that this compact unit maintains optimal cellar temperature and humidity conditions more effectively than similar units from competing brands. 1800XT-ECX units use energy-efficient EC fans and are significantly quieter than comparable units from other brands. Visit our Learning Center for data tables, performance charts and product comparisons among different brands.
CellarPro 1800XT-ECX units are sized to replace Breezaire 2200 and Wine-Mate 2500 cooling units. Please confirm equivalent dimensions and airflow prior to purchase.
Our cooling units are designed to be used in properly-constructed wine cellars that are adequately insulated, airtight and sealed with a vapor barrier. In improperly-constructed cellars, the cooling unit will create excess condensation, leading to damage and premature failure of your cooling unit (not covered by warranty).
- Now with energy-efficient EC Fans on both the cold and hot sides, save $26.02 in annual energy costs vs AC fans (assumes 75% runtime and $0.15/kWh)
- This unit offers a choice of top or rear hot exhaust. If the unit's location does not provide sufficient room for airflow, you may need to purchase a rear duct kit.
- Adjustable humidity control combines a high-output compressor with flexible fan cycles to maintain a recommended level of moisture inside your cellar.
- Extra-large coils generate maximum cooling power.
- Commercial-grade Electrofin coating protects the evaporator coils from leaks and corrosion.
- Intuitive LED display panel mounted on the evaporator with digital programmable thermostat is simple and easy to use. Remote thermostat is available as an upgrade.
- Energy-saver mode, quick-chill mode, and auto-defrost cycle provide convenient solutions to common cellar needs.
- Temperature set point range is 47F to 62F when the cooling unit is properly sized.
- Unit operates with minimal vibrations and less noise than comparable units from competitors.
- Audible and visual alarms and maintenance-needed indicator protect the cooling unit and the wine cellar.

DID YOU KNOW?
Nobody protects your wine cellar better than CellarPro Cooling Systems! In the event your cooling unit fails and the failed components are covered by our warranty, we'll send a replacement cooling unit to you per the terms of our Replacement Unit Program
CellarPro Replacement Unit Program
If your CellarPro cooling unit fails and the parts that failed are still covered by warranty, we'll send a replacement cooling unit to you, as follows:
- Your cooling unit must be registered at CellarPro
- Your cooling unit must have been properly sized, installed and maintained
- Your cooling unit may not have been permanently modified, damaged or disfigured
- Replacement units are factory-refurbished cooling units with a similar build date as your original unit
- You are responsible for the shipping cost to send the replacement unit to you and return the original unit to us, and the cost (if any) to remove the original unit and install the replacement unit
- In order to send a replacement unit, we require a deposit, which will be refunded minus shipping costs upon the return and pending the inspection of the original unit
- If the original unit failed due to improper intallation or use, the failure is not covered by warranty and we will deduct the cost of the repairs from the refund of your deposit
A: You should always use Sensible BTUH* when comparing different brands of cooling units, and when sizing a cooling unit for your wine cellar. Every cooling unit produces a certain amount of Total BTUH, which is the sum of Sensible BTUH (lowers the temperature) and Latent BTUH (lowers the relative humidity). Because our goal is to cool wine cellars while preserving humidity, wine cellar cooling units should have high Sensible BTUH and low Latent BTUH. The relationship between Sensible and Latent BTUHs is know as SHR (Sensible Heat Ratio), which is calculated as Sensible BTUH/Total BTUH. The SHR for CellarPro cooling units is greater than 90%, which means that CellarPro units provide maximum cooling power without stripping out humidity from the cellar environment.
*CellarPro Sensible BTUHs are calculated assuming 55F cellar temperature, 60% relative humidity and 95F ambient for all units except 1800 units (85F ambient).
How cold can the temperature be where the cooling unit is installed?
A: For installations in environments below 40F down to 20F, we recommend adding our compressor heater (P/N 1727), which is included as standard equipment on all outdoor units. Below 20F, in addition to the compressor heater, we recommend adding our fan cycling switch (P/N 6972)
How do I choose between top exhaust versus rear exhaust? What about the fresh air intake?
The fresh air intake will always come from the rear of the cooling unit, and must pull air from OUTSIDE the wine cellar space - it must never be installed to pull air from inside the cellar. On 1800 Series cooling units, the hot air exhaust can exit from the top or the rear. Choose whichever configuration directs the exhaust to a space that is sufficiently large to accept the exhausted air, as long as the exhaust goes OUTSIDE the cellar and will NOT intermingle with the fresh air intake. If you plan to duct the hot side of the cooling unit, then the hot air will need to exhaust from the rear.
Does the unit really need a dedicated circuit?
A: First, the background. Unlike our competitors, we build our cooling units with precision expansion valves, not cap tubes, which means that our cooling units aren't limited to a 30F differential between the desired cellar temperature and the ambient temperature. Cooling systems with expansion valves are much more precise than cap tubes, and much more sensitive to low voltage conditions, which is why our units require dedicated circuits. When we say "dedicated circuit", we mean that the circuit shouldn't have any items that require heavy draws of electricity - eg other appliances, vacuum cleaners, big-screen TVs, blow-dryers - on the same circuit as the cooling unit. Lighting, computers or other low-draw items shouldn't be a problem on the same circuit.
Can the cooling unit be located in a remote location and ducted to/from the wine cellar?
A: These cooling units can be installed above the wine cellar when used with our front intake hood.
Does the unit need to be installed through the wall, or can I install the entire unit inside the cellar?
A: These cooling units can be installed completely inside the wine cellar when used with our rear duct kit (P/N 1439), which allows rear supply and return airflows from a temperature controlled environment OUTSIDE the cellar to be ducted (with insulated ducting to minimize heat transfer inside the cellar) up to 100 equivalent feet (50 feet per duct).
What if I don't have sufficient space behind the cooling unit for the hot air exhaust to dissipate?
A: The rear of the cooling units can be ducted to another location by using our rear duct kit (P/N 1439), which allows rear supply and return airflows from a temperature controlled environment OUTSIDE the cellar to be ducted up to 100 equivalent feet (50 feet per duct).
Do I need the condensate drain line?
A: If you are using the cooling unit in a sealed cabinet, you probably don't need the drain line. If you are using the cooling unit in a cellar, we recommend the drain line, which can be drained inside (bottom) or outside (rear) the wine cellar. Choose the 100W heating element to reduce drainage as it helps to burns off excess condensate before it reaches the drain line.
Ratings & Reviews
by Tim -
I purchased this unit after my Wine-Mate 2500 stopped working. The main reason I chose the Cellarpro 1800XT was the operating temperature. This the unit can work in an area up to 95 degrees, 10 degrees more than the Wine-Mate. My old Wine-Mate simply could not keep up on on days when the outside temperature went above 90 degrees. It would run nearly constantly and simply heat up the garage.
<br>Over this last weekend, San Jose hit 108 degrees. My garage was at 91 and the CellarPro was not even running. It worked perfectly. Also this unit is dramatically quieter than the Wine-Mate.
1800XT Cooling Unit Review
by Axiom Construction Services
Wonderful cooling unit. Great price. I am contractor that build cellars and have used others at a much greater expense that don't last as long. The shortest duration of one unit was 9.5 years! Worth every cent.
Great unit and customer service
I needed a new cooling unit to replace a 16 year old Breezaire that finally gave up the ghost. I selected the CellarPro 1800xt based on the reviews and the dimensions are an exact match for my Breezaire. Bryan, the customer service rep was knowledgeable about the products, answered all questions, and got me the unit in two days. The unit was easy to install, the documentation is very complete, and I was able to get up and running within an hour.
Great custom service and advice
by Brady T
I had a vinotemp for 5-6 years and I was great till I needed something. <br><br>After 8-9 calls to the factory and a dozen or more to there 3rd party service provider I though I had it figured out. I had to call every local service shop they had and all but 1 said they wouldn't work on it (cause they don't like dealing with vinotemp).<br><br>Once I drove across town the guy said I would cost more to fix then a new one.<br><br>So now I'm back to square one, it's been 2+ weeks of a busted chiller and I still need an one.<br><br>I searched for a good price and found one on Amazon, sold by Amazon, but thought the factory would want to beat the price and deal direct.<br><br>She last took my number and said she'd call back, never did. Next day the listing on Amazon was taken down.<br><br>I will never buy another product from vinotemp, run around and bad rep seems to be they business. <br><br>Cellarpro actual answers their phones, knows about their product, and freely shares detailed information their product.<br><br>The units are well sorted, inside out side power cable options as well as venting options. <br><br>I highly recommend cellarpro to anyone considering the switch.
Glad to have found a quick replacement for my failed WineMate unit. The 1800XT fit excatly and works flawlessly.<br><br>Now to the criticism. CellarPro does not list a location on their website. I needed the unit ASAP as mine failed during a 100°+ heat wave. The website clained feee shipping but when I went to check out the free shipping was ground, would process in 3-4 days and take however long it takes to get from them to me. I obviously could not wait that long so I opted for Next Day Shipping. That evening I receive a shipping notice from FedEx showing the unit on its way coming from Petaluma CA which is 30 minutes South of me. I could have driven to CellarPro and picked up the unit the same day I ordered it and not paid $141 shipping. Or even opted for free shipping and still had it as soon as the overnight option. All for an omission from your website.<br><br>I sent CellarPro an email explaining this and my frustration over it. Never got a return email, phone call, letter in the mail... nothing. Unit is great, customer service/communication could use some help.
1800XT Cooling Unit
by Glenn M -
The Cellarpro rep was very knowledgeable /professional and responded promptly to my Cooling Unit needs. I received the unit within a couple of days and the Unit works great. Would purchase another one if needed.
Great Unit Great Service
by Mike M -
The unit I had was a Winemate and I could not get a service rep from that firm to return my call. I found Cellar Pro and thank goodness I did. My sales guy was exceptionally knowledgeable about the product I needed and spent a good deal of time with me on the phone asking questions to make sure he recommended the right unit. He also provided great advice on how to install the unit. I purchased the unit over the phone and it was delivered right away. I could not be happier. My wine cabinet is maintaining perfect temp and the unit is very quiet. Cellarpro is the way to go!
by Clever Construction
Bought both the Build 800 and a Cellar Pro 1800 XT for another unit.
<br>Installed as an upgrade to a 18 year old Vintotechque 450 bottle unit. fit into the existing unit but it is helped to have the little hanger clips from the old unit.
Wouldn't let me make a mistake
by Walther H
I am a licensed Handyman and I've built three "Wine Walls/Closet" for my customers. I just built a refrigerated wine closet from an existing wine closet for a customer. I had to dismantle all the racks in remove all the wood facnigns to get at the bones of the old closet.<br>The "new" area was properly sealed, waterproofed and insulated and the original wood liner and racks were reinstalled. The hole was cut and framed for the chiller.<br>I submitted all my dimensions, glass area, and insulation factors to CellarPro. I chose a unit.<br>I got a nice email back from CellarPro letting me know I probably chose the wrong unit. I had guessed from memory (faulty memory) at the closet size and the glass area. I re-measured t he next morning and called CellarPro to confirm and to help me calculate what unit I Needed. The new calc with the "real" sizes showed I ordered correctly, but the unit was on the "edge" for cooling capacity.<br>CellarPro advised me that for the same $ I could go to the next larger unit.<br>They would not let me make a mistake - my customer is a "snowbird" and returned to see their new, refrigerated wine closet. They loved it and are so very happy.
Working perfectly after two months
by Frank W
I replaced a Wine-Mate unit that had failed after six years with an 1800XT. Installation took only a few minutes as every part matched and the new unit dropped right into place. Unfortunately the ambient temperature on the first day was at the upper limit of the CellarPro's range, and the unit overheated after a couple hours. I rearranged the venting and put a small fan in place until my wine cabinet reached the desired temperature. I have since removed the fan and restored the venting to the original state and the CellarPro has been working perfectly. The CellarPro is considerably quieter than the Wine-Mate and seems to run less, although the ambient temperature is lower now than when we started. It's nice being able to not worry about my wine, so I've started buying wine again...
CellarPro 1800 Cooler Repair
by Richard M
Outstanding response and thank you for standing by your product.
Excellent Wine Cooling Unit!
I highly recommend the 1800XT. It has been extremely reliable and has cooled our wine cellar perfectly. We had a problem with our unit not cooling after 3 years of use and Cellar Pro's customer service has done everything to insure that our problem is solved. I only wish the return shipping was paid for with a return shipping label.
Excellent Unit so far--9 months report
I bought the 1800XT in March 2015 after considerable research. I replaced a cheap Chinese unit that failed after a year--then the seller sent me a new one that failed after a year! So I was skeptical of everything. But this unit is doing fine. I have a closet that I insulated A LOT. It is about 120 cu ft. It holds about 40 cases and I keep it quite full. The CellarPro has done everything that they said it would. It cooled the space down very quickly, almost with no condensation. I never get water. It runs reasonably quiet in my installation (all interior walls, and around the corner from the living room and down a little hall. It vents into the laundry room which is on the next room (away from the living room). It might be rather distracting if it vented into a living room. But down the hall is fine--not too loud. It keeps the temperature perfectly between 56 and 60. It seems to be on about 1/4 of the time. That does not seem to vary with the outside temperature. It is still running strong--much more air flow than the old Chinese one. I vacuum the back fins monthly. I will continue keep posting progress reviews at least yearly, because longevity is important PS I also was pleased to be able to talk to very knowledgeable people directly at CellarPro.
i have an old school Vinotemp with a dead breezaire. The 1800XT was a perfect fit to replace the Breezaire, and after we read the directions (haha), it installed easily. So far, very very happy.
So Far So Good
Unit is running in a hot garage and keeping the wine at a cool temp. I do not have a bottle probe so I am unsure if the wine is cooled to the exact temperature, but by feel the bottle seem to be properly chilled. I would recommend this model for the above stated environment and I intend to order the bottle probe.
1800XT Product Review
I installed my Cellar Pro 1800XT about a month ago. It runs cool, and the fan moves a lot of air. It is pretty quiet, but I am glad it is down the hall and venting into a room away from the living room. It is running about 1/4 of the time, and I am very happy. I ran through three cheap Chinese coolers. No good--they do not last much over the one year warranty, Fortunately the seller heavily discounted the replacements, but after the third on I gave up.<br><br>I will try to remember to re-review this unit at the end of each year I own it. It seems to be a very good unit. DO get the clips for mounting!

Compact self contained system. Easy installation.
1800XT Product Review
by Angela Mullen
Our last wine cooler box, a whisper Kool, died suddenly after only 2 years of use. So we had a contractor friend ask around about other coolers. Cellar pro 1800XT came highly recommended but we did our own research anyway and found that other folks agreed that this was the unit to get. Our basement gets hot both more in the winter than summer, so we need a unit that can operate at higher than normal temps. It is much quieter than our old whisper Kool. We also purchased the filter that attaches by magnetized strip to the back since it is just above my workbench and dust is can be an issue on rare occasions. All in all we like it very much and found it to be well worth the the price tag, so far
Excellent performance from the 1800XT
by A McCall
The 1800XtT was a direct replacement for my Winemate. The installation was easy. Do buy the mounting clips. It's curious that they are offered as an option instead of just being included with your purchase. I'm mechanically inclined and I would not attempt installing the unit without them (not worth the hassle). The system cooled my 440 bottle cellar with glass doors that I had loaded with about 150 bottles in less than four hours. The digital display is easy to use and I have it set at 57 degrees. I store the unit in my garage and it's surprisingly quieter than I had expected. During the heat of the day it typically cycles on and off every fifteen minutes. I also purchased the optional air filter that magnetically attaches to the rear of the unit. The magnetic strips that hold the frame onto the unit hold, but barely. If you're looking for maximum longevity of the unit seems like cheap insurance to me. All in all I'm very pleased with the performance of the 1800XT.
by M Moore
the unit was an exact fit for replacing my Breezaire 1060 - it simply slid perfectly into the opening in my 300 bottle cabinet. Its working perfectly and is much quieter than I expected. The writeup says the smaller unit is quieter but the 1800 is much quieter than the old Breezaire.
Great new unit
by Antony Francis
I just replaced my 13 year old LeCache original unit and switched to the Cellar Pro 1800XT. My cabinet is in my garage (in Dallas it is 100 degrees at present). The 1800XT was easy to install and is doing a great job. I resealed all corners and the seams while the wine was out and everything is now cooling at 60 degrees ...
First the good. The unit is dramatically quieter than the Breezaire unit. It seems to be a little more efficient in that it runs a little less, but that may be because the Breezaire unit was losing refrigerant. The control panel is much more sophisticated than the Breezaire as well and the humidity in the cabinet is about 10 percent higher (which is good. The Breezaire maintained about 50 percent and I'm in Florida. Sixty is a much better number.)
<br>Now the bad. It is not a matter of removing one unit and replacing it with the new one, at least not in my cabinet. I've replaced Breezaire with Breezaire in the past and it was really just a matter of removing and replacing, then resealing to eliminate outside air entry into the cabinet. My cabinets are both Vinocraft units from around 1999. They both exhausted upward and also took in fresh air from the top, with a grill directing exhaust air to one side and intaking from the opposite side. The unit was hung from the top of the cabinet and the rear of the unit rested on the rear of the cabinet. First of all, the dimensions stated do not include the front grill. Also, with the configuration of that grill, it must be removed to obtain an air-tight seal between the top front of the unit and the top of the cabinet. This detracts from the appearance of the unit. Also, the clips that allow you to hang the unit are pretty flimsy, but they do work. However, the height of the clips is different from those on the Breezaire. That was corrected by building up the rear of the cabinet so that the new unit would sit at the proper level. Finally, the entire cabinet needs to be moved away from the rear wall at least 8 inches. Esthetically, this might be a problem for some.
<br>So, in conclusion, now that it's done, I'm very happy with the results. I'm disappointed that I have a large space behind the cabinet which I didn't have in the past. But someone sleeping in the next room won't be awakened by the rumble of the old Breezaire. And the humidity in the cabinet is better. Also, my first Breezaire units both lasted 11 years. One of the replacements lasted less than 3 and that’s unacceptable. The cost of repair (it wasn’t the compressor) is exorbitant and the only option offered is to send the unit in for refurbishment. What happens to the 700 bottles of wine in the cabinet while you’re waiting for the unit to be returned?
Works great so far
by Chris Shaker
Used this to replace the heavy duty cooling unit in my 12 yr old Vinotemp 600E. This cooling unit is much quieter, has a control panel (which old one did not have), looks better, and is working great so far in my garage.I emptied out the Vinotemp and turned it 90 degrees to the wall, so that the air intake/exhaust is in free air, and so that it can be vacumned easily.
<br>The original clips worked great for installing this, so I wasted money on buying the new clips
Great Breezaire replacement
by James C
Purchased to replace old Breezaire. Helpful telephone sales rep. Delivery was prompt and unit was easily installed and activated. It is a big improvement - I really like the digital display. We have been in a bit of a heat wave and the unit is working perfectly. So far, excellent.
purchased this unit to replace a BYO Wine Enthusiast EW 800 cooling unit
by Tom S.
The CellarPro 1800 XT arrived on time and well packed. i removed the unit and let it sit for 24 hours as directed in the installation instructions. I then plugged the unit in to test it for proper operation, fans, cooling etc. I had to make the rear opening of my wine cellar larger , since the EW 800 (the original cooler) is a smaller unit , but that was not a big job. While i had my wine out of the cellar i took this time to also re-calk all the seams from inside and out to insure a good seal. Once the unit was installed and properly sealed (with sealing putty included with the unit) i plugged it in and it began to cool my cellar immediately , much quicker than the original cooler. Per the instructions i put my cooler into its "quick chilling" mode several times to get the bottles cooler quicker since they had been sitting out for 6 or 7 hours while i was performing this installation. This cooling unit is now cycling on and off much less often than the original unit, it is quieter as well. i also want to mention before purchasing this unit i called the 800 number and got very good advise as to which unit i should purchase for my needs and I purchased the extended warranty for five years , its is a good value should i need to have this unit repaired in the next five years. I have only had this unit for a few days but feel it will be a great asset to protecting my wine investment since the company seems to very professional in every aspect of its dealings.
