CellarPro 4200VSi Cooling Unit #1079
CellarPro's 4200VSi cooling units (1/2 Ton Nominal) are suitable for wine cellars up to 1,000 cubic feet in both commercial and residential wine cellars. The 1,000 cubic feet cellar size assumes that the cellar is constructed with insulation of R19 or better in all walls and ceiling (ie no glass or uninsulated concrete), the cooling unit is not ducted, a setpoint of 55°F inside the cellar and ambient temperatures up to 85°F outside the cellar.
Performance testing shows that this unit maintains optimal cellar temperature and humidity conditions in extreme conditions up to 115°F more effectively than similar units from competing brands. 4200VSi units also 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 4200VSi units are self-enclosed, fully-charged units designed to be installed through-the-wall and sized to fit in between standard wall studs.
- 4200VSi units also can be located remotely from the cellar with the addition of one of our front duct packages. Offered with or without insulated flex ducting, in a choice of configurations for low or high humidity conditions, our front duct packages allow these cooling units to be ducted up to 50 equivalent feet away from the cellar and requires 8-inch (or greater) ducting from start to finish.
- When calculating equivalent feet, each 90-degree turn counts for 8 feet.
- For remote or inaccessible installations, we offer a remote control display kit which is wired to the cooling unit and allows the digital display to be mounted inside or outside the cellar.
- 4200VSi units require fresh air intake at the rear of the cooling unit. If sufficient space does not exist to provide sufficient airflow to the rear of the cooling unit, you may need our rear duct kit.
- 4200VS Series cooling units can be installed completely inside the wine cellar when used with our rear duct kit, which allows you to duct the supply and return airflows from the rear of the cooling unit up to 100 equivalent feet (50 feet per duct).
- For installation in environments below 40F, 4200VSi units require our Compressor Heater (P/N 1727) .
- For installation in environments below 20F down to -20F, we recommend our Fan-Cycling Switch (P/N 6972) combined with our compressor heater.
- The front of the cooling unit should never be exposed to temperatures below 32F.
- A CellarPro cooling unit must always be used in the upright position, and should never be operated on its side or upside down.
- We ship these units strapped to a pallet via common carrier with curbside delivery. Inside delivery is available for an additional charge.
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.
- This unit can be configured to operate in extreme temperature conditions (-20 to 110F). If the unit's location does not provide sufficient room for airflow, you may need to purchase a rear duct kit.
- Dual high-output centrifugal fans come with variable speed settings for your choice of maximum cooling power at the high fan speed, or super-quiet operation (53.7 decibels) at the low fan speed.
- 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 inside the cellar.
- Excess condensate is managed with a high-capacity stainless steel drain pan, welded 1/2" drain line and 200W electric heating element with "On/Off" Control.
- 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.
- Common dedicated 15-amp circuit is required to power the unit.
- With dual power sources and a 10-foot power cord, the unit can be plugged into a receptacle from either the front or the rear of the cooling unit, providing flexibility for most installations.
- Our easy-access disposable air filter protects the condenser coils and increases the expected useful life of the cooling unit.
- Adjustable mounting brackets, included as standard equipment, ensure easy installation.
- Removable steel case and refrigerant access valve provides access to the internal components for servicing and repair.
- CellarPro's 5-Year Standard Warranty, the most thorough in the industry, protects the unit against manufacturing defects.
- An optional Extended Warranty (P/N 1836) is available for additional protection.

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: 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)
Can the cooling unit be located in a remote location and ducted to/from the wine cellar?
A: These cooling units can be ducted up to 50 equivalent feet away from the wine cellar when used with our cold-side (front) duct hoods and kits. Remember that cold-side ducting must be insulated and additional load should be added to properly size the required cooling unit.
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 I install the entire unit inside the cellar?
A: These cooling units can be installed completely inside the wine cellar when used with our hot-side (rear) duct hoods and kits, which allow 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).
If I don't have sufficient space behind the cooling unit, is that Ok?
A: The rear of the cooling unit generates hot air that must have sufficient space to dissipate, otherwise the unit will recycle its own hot air. The hot air exhaust and/or intake can be ducted to another location with our rear duct hoods and kits, which allow 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).
Can I use the low fan speed setting on the cooling unit when the unit is ducted?
A: Duct hoods and kits create additional static pressure and therefore require the use of the high fan speed to overcome the additional static pressure.

wine drinker and cellar builder
fits nice, looks nice and keeps my wine prefect temp
by Vic T
I wanted to say that CellarPro packaging is outstanding. Necessary parts are always provided in their respective packaging.
by Alex R. -
The Quality products and professional but personal service at Cellar Pro is Amazing. They are the only cellar supplier we use and recommend to our customers.
Had to replace my original BreezeAir which lasted maybe one year. Decided to go with CellarPro based on reviews and quality. The unit is not in a desirable location being in the attic on the 7th floor of a condo in Hot Atlanta. However it has performed nicely until the rear fan motor died. Decided to replace with a new CellarPro 4200 since the previous unit was a workhorse for many years. Would highly recommend CellarPro and the customer service are first rate.
Great customer service
by Nick F. -
I had a wine room built as part of a new house. My builder chose the wrong size unit then washed their hands clean of any responsibility. The team at cellar pro were quick to assist even though I was not the one who purchased (builder bought but I paid) and quickly determined I needed a larger unit. I could have gone with the 3200 but decided to have larger 4200 just to be safe. The team walked me through all parts I would need to make my system work. I am happy to report the system is installed and my 300 bottles collection is happy in the 58 degrees chilled cellar. The team also took my smaller unit back and assisted with arranging shipping. To say I am impressed is an understatement. To Ben and Q and the rest of the team thank you.
new wine closet
I just moved into a new home that did not have a wine cellar. I had a Cellarpro 4200VSI in my old wine room and it worked well. I had an issue with the compressor but had it replaced. My new wine room is a bit smaller and I am using the same size unit. This system is ducted at both the front and back of the unit. It is mounted in my attic outside the wine room space. The unit is not in operation yet. I'm impressed with the increase in quality from my last purchase (2010) to now. Customer service has always been responsive & very good.
Much better than Whisperkool
by Braden -
Replaced Whisperkool unit for third time. This last one lasted only 20 months. One before that 3 months. Went with Cellar Pro 4200 CSU unit for a change and am impressed so far with the performance. It easily keeps my 920 ft3 Cellar at 57 at medium fan speed. The installation was easy although some sort of weatherstrip was not included to seal the small gap between unit and frame out.
Came just as described. Jimmy was exceptionally helpful. Took time to make sure it was the right system and that all questions were answered.
Outstanding Unit and Great Customer Support
I have a 1000 bottle cellar in my vacation home in California's Gold Country in Amador County that I built in 2005. It is 100 miles from my primary home in the SF Bay Area. I've replaced 3, yes 3, cooling units that were made in China that I purchased from fill in the blank.Enthusiast.com. Every year they would freeze up and I'd have to drive up and thaw them out. I purchased and installed the CellarPro 4200VSi in October 2016. Here in Northern California, the weather this year has been extremely hot with outside temps exceeding 100 degrees F. This unit has handled the temps without any issue at all. While it automatically circulates air in the cellar every 15 minutes, it only switches into "cooling mode" every couple of hours. My cellar stays at 58 degrees and my electric bill is significantly lower than with the other coolers. What's more, the humidity is about 20% higher than with the other units. I'm sure there is a technical reason for this, but what really matters is the impact on my corks. And I haven't had to make emergency trips to the cellar to deal with failing cooling units and frozen coils. These units are the "real deal". Don't believe the false claims of BTU ratings from others. Customer service has been exceptional. I've called them twice about technical details and they were responsive and straight-forward in their responses. These guys know what they are doing !
by J Fetherston
Replaced a Breezaire, that was only 18 months old, with a Cellarpro. Extremely happy with the unit. It was painful to eat the cost of the Breezeaire but well worth it. The performance difference is remarkable.
by L. Taylor
Very happy with my Cellar Pro. It arrived sooner than expected, was packaged very well, installed easily, and Bryan followed up with me regularly. The unit is performing very well in my cellar. Wish I bought this the first time!
by Ed Wagner
The minute I opened the box I was immediately impressed with the quality of the packaging and upon seeing the unit had great confidence the 4200VSI would do the job. The installation instructions were very clear and straight forward. I recommend following the cut dimensions closely to ensure a tight fit. Also, the unit is heavy so be prepared to have at least two strong individuals when placing in your wall. The unit is very quite and controls both temperature and humidity exactly as needed. I have great confidence this unit will last many years to come.
by Sonray Construction
A very easy to install and excellent product. Great for a DYI or contractor. We have recommended this unit many times. Also the best sales and customer support I have ever dealt with.
4200VSi Review - Cooling Beautifully
by Tofanelli Wines
Installed the 4200VSi last evening. Have to say, out of the box the unit looked less like an air conditioner and more like a piece of serious audiophile sound equipment! Quality,fit, and function is impeccable. Of course it's cooling beautifully! I may have some questions in the coming weeks but for now, hats off to you and CellarPro!
by Robert -
Very easy to install and it cools down the room impressively. Make sure you vent is properly though as it puts out a lot of heat. I'm now sorry I didn't vent this to the outside and easily could have. The first unit that was sent was defective and one other piece of advice is to fire it up and make sure it is blowing cold air (we did fire it up but didn't realize it wasn't actually cooling). Replacement process would have been painless but we had to uninstall the unit. Otherwise very happy.
by Ron B -
A quick note to says thanks for the great service and technical support that I received following my purchase of a 4200VSi cooler. My install was difficult because of location, but with the assistance of Ben A and his technical team, the job went very well. I was particularly impressed when I posted a question to your website via email and had a return message the next day with an offer for me to call Ben on his cell number (on a Sunday, no less). Great equipment, exceptional people and an excellent experience. Thank you!
Love this CellarPro Cooling Unit
by Chris S
Absolutely love this cooling unit. I have a 2,500-bottle wine cellar and I need flawless performance from a unit. This delivers 100%. Best decision I made was purchasing this unit!
My replacement fan was shipped when I was told it would be & contained great directions and a contact if I had a prob. Great company!
Installed this to replace a Breezair unit that failed after 6 years. The 4200Vsi is much heavier than the old one and seems much better built from the outside. It is also more expensive and I hope it's one of those 'you get what you pay for' situations. I really like the 3 speeds and it is also quieter than the old unit. FYI, the unit comes on a pallet and I recommend help to get it unloaded. I have a small tractor with front end loader and that made it easy.
CellarPro 4200 Vsi DIY Install
Replaced a Breezaire unit that leaked water and wouldn't keep my cellar a consistent humidity and was extremely noisey. I mounted this unit in my cellar and used the rear ducting. Temperature and humidity are in the perfect range and I can not hear it running outside of my cellar. I wished I had purchased this one first.
CellarPro 4200VSi DIY Install
by Barry K.
Received 8 years of reliable performance from our last unit (Koolspace), but it was way undersized for the task of cooling my cellar so I needed to upgrade. Had my eye on the Eurocave INOA self-contained tower unit, but after a long and helpful discussion with the excellent Customer Service folks at Rosehill Wine Cellars, I settled on the CellarPro unit instead. Glad I did.
To convert from the wall-mounted unit to a ducted register system, I included the front duct kit, which also required the remote control kit. The conversion project was a somewhat complicated (and fun, in a way that only us DIYers understand) installation job overall, but NOT because of any fault of the CellarPro unit. The 4200 appears to be well-built, it is fully capable of maintaining the proper temp range in my cellar, and it is quiet during operation. The price seems fair for the quality, capacity, features and warranty, and considering the amount of money that I have invested in the wine in my cellar, it was an easy decision once I settled on the proper unit.
As a side note regarding humidity; Per the suggestion in the instructions, I added foam insulation to the outside of the supplied duct kit pieces, and additionally I ordered a small, 2.5 GPH in-pan condensate removal pump (EC-400) from PexSupply.com to handle any drainage come summertime, since the unit is located in an area of the house where I cannot just let any condensate drain freely. California has very low humidity, so I don't need a larger HVAC-rated condensate pump. This unit is handy because it has a self-contained sump pan w/float included, so the installation is very easy.
Very impressed with the unit overall, and a fun and satisfying DIY chore for those who have some reasonably strong experience (and a strong back-it is a bit heavy). My wine sleeps well, and so do I.
Installed unit after other brands failed too soon. Runs very quiet. Appears sturdy. I like the air intake filter (absence was a problem with other brands). While heavy, I think the published weight must include packing material. I suggest you rent a duck lift (essentially a manual fork lift) it is safer than a second person to install unit. Staff worked well to arrange a shipping date that worked for me. It was pricey, especially with the extended warranty, but if it lasts will be worth it.
CellarPro 4200VSi Cooling Unit
by Steve T
Installed the unit about 3 weeks ago, easy to install if you have help lifting it in place, it is heavy. This is the 3rd cooling unit I have purchased in the past 5 years, the first 2 (other brands) failed after about 2 1/2 years of use so I decided to spend more for a higher quality one. Right away you can see this is a solid unit compared to the others. Fired up right out of the box and got to temperature with ease in my 1,000 CU FT cellar. Holds temp well with little effort @ medium setting using 5-6 kWH a day in electricity in a well insulated cellar with 85-90 degrees outside temps.
- Look and feel tells you this is higher quality than many others I have seen
- Maintains temps with ease
- Very quiet
- Price, but if this lasts it will be worth the extra $$
by Lou Galie
Absolutely perfect for my needs. Quiet, and the temperature of the cellar is rock-solid steady. I highly recommend the unit and the company. I wasn't sure exactly what accessories I needed, and ordered more than should have. The people at Cellarpro got in touch with me immediately, asked questions about how I intended to install and use the unit, and made sure they shipped only what I needed. I recommend them highly.
by Bill and Stephanie
Thought I would let you know that the unit we bought is perfect. It is not just quiet but I consider it silent.
The temp NEVER changes – it stays at a constant 57°. We are so glad that you were able to guide us in the right direction.
