Split Cooling Unit 2/5 Ton 4000S-EC #1763
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. The Evaporator can be remotely located and ducted to/from the cellar using our cold-side duct hood, or located inside the cellar (with or without a decorative grill - not included.)
CellarPro's 4000S-EC cooling units (2/5 Ton Nominal) are engineered for wine cellars up to 1,000* cubic feet in both commercial and residential wine cellars.
Performance testing shows that this unit maintains optimal cellar temperature and humidity conditions in extreme conditions up to 110F more effectively than similar units from competing brands. 4000S-EC units use energy-efficient EC fans in the evaporator 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.
*Assuming R19 insulation throughout the cellar, 55F inside the cellar and 85F outside the cellar. Cold-side ducting, glass and/or uninsulated walls, extreme humidity, altitude and other factors may affect the sizing calculation.
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).
Please note: Our units were not designed for, and our warranty does not cover damage from, marine exposure (within 5 miles of the ocean). In these environments, you will need an applied coating, such as Insitu®, to protect outdoor components against corrosion that is common in coastal regions.
- Now with energy-efficient EC Fans on the cold side, save $90.37 in annual energy costs vs AC fans (assumes 75% runtime and $0.15/kWh)
- This unit is designed to separate the heat and noise from the condensing unit from interior living spaces, and can be configured to operate indoors or outdoors in extreme temperature conditions ranging from -20 to 110F.
- Our Evaporators are built with high-output centrifugal fans which include variable speed settings for your choice of maximum cooling power at the high fan speed, or quieter 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 through a 1/2" drain line that exits from a choice of knockouts in the evaporator.
- 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.
- Adjustable mounting brackets are included as standard equipment, and multiple knockouts and access points ensure easy installation.
- Factory-installed Expansion Valve and Liquid Line Solenoid Valve (optional) ensure maximum operating precision and range.
- Removable steel case and refrigerant access valve provides access to the internal components for servicing and repair.
- Sight Glass and Liquid Line Filter/Drier are included for easy installation and maintenance.
- Oversized Receiver allows for long line sets up to 100 equivalent feet and up to 30 vertical feet.
- Auto-reset high-pressure switch protects the system by interrupting power to the compressor when system pressure is too high.
- Evaporator and Condensing Unit are factory-pressurized and shipped with dry nitrogen to ensure leak-free installation.
- CellarPro's 2-Year/5-Year Warranty, the most thorough in the industry, protects the unit against manufacturing defects.
- An optional Extended Warranty (P/N 7528) is available for additional protection.
- ETL Tested and Certified to rigorous UL Standards for safety.
- CellarPro 4000S-EC units are designed to be installed with the evaporator inside the cellar, and the condensing unit in a remote location.
- Our Split refrigeration systems offer a choice of wiring:
- The Condensing unit can be electronically controlled by and wired to the Evaporator (single power source on the Evaporator side). A compressor heater is included to prevent off-cycle refrigerant migration to the compressor, and allows the Condensing unit to be used in temperatures down to 20F, or down to -20F with the addition of our fan cycling switch. This configuration requires a 15-amp dedicated circuit breaker for 3000S-EC and 4000S systems, and a 25-amp dedicated circuit breaker for 6000S and 8000S systems.
- The Condensing unit can be controlled by a Solenoid valve (dual power source, one each to the Evaporator and Condensing units.) A compressor heater is included to prevent off-cycle refrigerant migration to the compressor, and allows the Condensing unit to be used in temperatures down to 20F. We do not recommend using this configuration when the condensing unit will be exposed to temperatures below 20F. This configuration requires the evaporator to be wired to a 15-amp circuit breaker, and the condensing unit to be wired to a dedicated 15-amp circuit breaker for 3000S-EC and 4000S systems, a dedicated 20-amp circuit breaker for 6000S systems, and a dedicated 25-amp circuit breaker for 8000S systems
- 4000S-EC evaporators 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.
- When the control panel is difficult to access, 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.
- The condensing unit requires 12 inches of unobstructed space in front of the coils, and requires approx. 600-700 CFM of ventilation when installed in a confined space.
- For outdoor installations, we offer an outdoor hood to protect the condensing unit from weather.
- The evaporator should never be exposed to temperatures below 32F.
- Access to the left and right side of the evaporator unit is required for installation.
- All split systems must be installed and charged on site by a qualified HVAC professional. Line-set equivalent feet must be calculated in accordance with ASHRAE guidelines; refer to our Line Sizing Chart for more information.
- 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.
- To activate your warranty, you must complete and return our Installation Checklist.

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).
What's the difference between a split system and "through the wall" or "self-contained" systems?
A: Split systems are "split" into two parts: the cold side (evaporator) which usually is installed inside the cellar, and the hot side (condensing unit) which is installed away from the cellar. The benefit of having this split is that the heat and noise from the condensing unit can be located far away from living spaces where it won't interfere with day-to-day life.
Are split systems more difficult to install than self-contained systems?
A: Yes. Split systems require installation by a licensed HVAC technician, whereas a self-contained unit can be mounted through-the-wall and is shipped fully charged and operational out of the box.
What's the difference between valve control and electronic control? Which is better?
A: The biggest difference between valve and electronic control is that, with electronic control, the condensing unit receives power directly from the evaporator, whereas with vavle control, the condensing unit is independently powered, and turns on/off based on the solenoid valve. Valve control is more common in the industry, and benefits from not having to run a power line from the evaporator to the condensing unit, but we do not recommend valve control for installations in temperatures below 30°F. Electronic control offers more precision, and allows the condensing unit to be placed in temperatures down to -20°F (with the addition of a compressor heater and fan cycling switch.)
Can the evaporator be located in a remote location and ducted to/from the wine cellar?
A: These evaporators 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.
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.
Can I install the entire unit inside the cellar?
A: No, the condensing unit must be located outside the cellar.
If I don't have sufficient space around the condensing unit, is that Ok?
A: The condensing unit generates hot air that must have sufficient space to dissipate, otherwise the unit will recycle its own hot air. The condensing unit cannot be ducted; it requires 12 inches of unobstructed space in front of the coils, and requires approx. 600-700 CFM of ventilation when installed in a confined space.
Does the evaporator include flare connections, or will I need to braze the connections to the line-set?
A: Flare connections are much more prone to leaks, and have been phased out over the years, replaced by fully-brazed connections. This is driven by the EPA and the focus on minimizing refrigerant leaks into the atmosphere.
We want to put a wood grill in front of the evaporator, what is the percentage of air flow that grill will need to have?
A: Our units require 1/2" minimum spacing, as well as a baffle behind the grill to separated the cold air discharge from the coil intake. We have seen problems with custom grills where there is a gap between the unit and the grill and it causes air circulation behind the grill resulting in coil icing. It is also important to note that the evaporator must be mounted to the interior cellar wall, not buried inside the wall. If it is buried inside the wall, the housing will require insulation, otherwise condensation and heat loss issues will occur.
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 30°F 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.
Ratings & Reviews
I wish I knew about this unit sooner
After multiple repairs on my old breezier I was ready for a new product. After installation, right out of the gate this system is quieter, very user friendly to program and is very efficient. It is maintaining the temperature spot on and runs circles around the prior breezier ( which had to run twice as much to maintain the same temperature) I also love the fact that it has different speeds and works beautifully on the low speed. I am very happy with this new unit. Also great support for recommendation on which unit would work best for me and they were spot on!
Looks like a great unit
My 4000s is being installed as I type this. I really like the fit and finish of both the evaporator and the condenser. I was sort of expecting a flimsy outdoor condenser cover, but am really impressed by the metal thickness, definitely not flimsy. Will update my review after the system goes live.

this is my second installation. they have become quite easy to install. good quality
by Scott Tucker
A great system. Vastly superior to our previous unit Whispwr Kool .
Better than Breeze Air
by Robert, Advanced Mechanical Systems
The installation is complete, This unit is head and shoulders above the Breeze Air unit I removed. The unit started up well and no problems encountered. My amp meter had a malfunction and I got no readings from it and assumed full load at start up with a 75 degree room and 90 degrees outside.
CellarPro 4000S Split Cooling Unit
It's working beautifully
I have not installed the unit yet, but I was disappointing to discover I will need to reach into the evaporator cabinet, and braze fittings onto the stubs to increase to the line sizes required. To me, this is sloppy manufacturing. You know what the line size needs to be. Why not give me some nice flare connections in the size I need? That way I wont be trying to braze inside a little metal box with an acetylene torch.<br><br><b>Reply from CellarPro</b><br>Thank you for your feedback. Flare connections are much more leak prone and have been phased out over the years, replaced by fully brazed connections. This is driven by the EPA and the focus on minimizing refrigerant leaks into the atmosphere. The stubs inside the unit allow flexibility in routing the lines. Adapters and bushings are commonly used in refrigeration piping.
by Greg, 72 Degrees
Good afternoon. The install went great and the unit is quiet and I have happy clients, thanks to CellarPro and the great products you make! Can I get some color brochures? I have a lot of clients that are looking at getting wine closet’s or cellar’s in their home, and any good product info will be good from your company.
