Smooth, quiet and long-lasting

A wine cellar air conditioner, the CubeLT works using an Italian compressor that can be installed up to 100' away from the wine cellar, keeping the noise out of the living space. It generates 400W (1400 BTU/h) of air conditioning power.

This cooling system is intended for cellars that are glazed and shallow, in which the air conditioning unit is located just above the wine bottles. Its water loop cooling (in closed loop) allows air conditioning at higher temperatures (8°C compared to -4°C normally), reducing thermal shocks and drying the air in the wine cellar, which means, better aging potential for wine, in a more humid wine cellar. Developed in 3 modules, this unit offers quick and easy installation. Whether for residential or commercial projects, the CubeLT lends itself to any environment.

  • Designed for both service and storage
  • "Split" type system, allowing the compressor to be installed remotely from the wine cellar
  • Easy to install, can be installed by anyone
  • Access CubeLT data via the mobile application
  • Installation in a mechanical room or garage
  • Environment: No refrigerant gas is used
CubeLT Statistics

An interface monitors and records the state of the wine cellar to maintain the ideal temperature for storage. An alert is sent to you as soon as a problem occurs.

Connected Wine Cellar

The device's connectivity technology syncs with your computer or mobile device, allowing you to view data at any time.

Hearing comfort

This solution is designed to limit the harmful effects of noise caused by traditional cooling systems thanks to its split type configuration that allows the noisiest unit to be installed up to 100' away from the wine cellar.

Modular system

Designed as three distinct modules, making service or replacement of one of module easy, economical and fast. The compressor, the most stressed element of the system, is independent and easy to replace when it reaches the end of its life. Cutting-edge engineering is behind the CubeLT.

The CubeLT

The CubeLT is a wine cellar cooling system made up of three modules. First, a water loop acts as a connector between these three modules to pump heat out of the wine cellar. This same water circulates continuously in a loop between the three modules. It should be noted that this system does not consume water and is not connected to the building water supply.

Then, a compressor unit, located away from the wine cellar (usually in a mechanical room or garage), constantly cools the water in the system's air conditioning loop. This water is then routed to the diffuser in the wine cellar via the control box.

The control box continuously monitors the conditions in the wine cellar and via its control algorithm, adjusts the cold water supply to the diffuser in the wine cellar.

The diffuser in the wine cellar, RC4LT, pumps the heat in the wine cellar and injects this heat into the cold water loop which then returns to the compressor unit.

This cooling loop, like a standard system, is done without refrigerant gas (which can affect the health of the occupants of the house in the event of a leak) and at a higher temperature, thereby reducing the thermal shock to the bottles near the diffuser. In addition, this higher temperature air conditioning eliminates the drying of the air due to the compressor.

This system is therefore the most suitable for the glazed cellar on the ground floor. In this type of installation, all the bottles are close to the cooling system and are at risk of suffering from thermal shocks generated by the operation of a standard system. In addition, by having the compressor unit remote, this system does not emit noise outside the wine cellar.

A state-of-the-art system for storing wine without making noise outside the wine cellar.

*** The noise level of an air conditioning system (dB) for a wine cellar is rarely the main irritant. Like dripping water, it is the stop/start every 10-15 minutes that pushes the owners of "through the wall" type systems to unplug their device after a few months. In the case of a wine cellar within the living space, ''split'' or ''ducted'' type systems are the only option to consider to stay sane.***

Components that guarantee success


  1. The CubeLT is a split-type wine cellar cooling system. This feature allows the compressor to be moved a good distance from the wine cellar, keeping noise away from the wine cellar.
  2. Composed of a control box, a water cooler and an RC4LT diffuser, the cooling unit maintains an ambient temperature between 54°F and 64°F ​​as well as a humidity level of 50 to 80%.
  3. The solution offered by The Wine Square combines power and reliability to allow an ideal storage and tasting temperature for most red wines.

RC4LT Diffuser

The RC4LT is the cooling unit located on the ceiling of the wine cellar. This is where the heat is pumped and routed to the water cooler. The diffuser makes it possible to evacuate the condensation outside the wine cellar. It must be installed at the highest point of the wine cellar.

Water Chiller

The water chiller provides water at the temperature necessary for the correct operation of the appliance. It is a small, very robust unit that uses a refrigerant gas that is safe for your health, R290, a non-toxic refrigerant gas with zero ODP (Ozone Depletion Potential) and a very low GWP (Global Warming Potential).

The cooler is installed close to the control box and emits a low noise level, comparable to that of a dehumidifier. It is usually installed in a garage or mechanical room.


Control Box

The control box represents the management module for the whole system. It has a touch screen that allows the display and simple adjustment of the conditions of the wine cellar. Permanently connected to the Internet, this module monitors and adjusts conditions in the wine cellar. Ecological and safe, it reuses the same water to ensure the operation of the cooling unit.


Comparison of CubeLT with other systems on the market



SPLIT System


Quiet, durable and stable

Innovative engineering packs so much quality into one product. The precision provided by this thermoelectric device compares to that required by medical laboratory devices, and you can have it right in the heart of your wine cellar.

Choose a reliable device that blends harmoniously into your environment while offering performance worthy of laboratory equipment. The integration of an advanced electronic system offers you a connection accessible at all times, and can provide our technicians with the data necessary for remote diagnosis.

Powerful, aesthetic and ecological

The cooling system for wine cellars CubeLT is a solution designed for wine cellars that are glazed and shallow. This compressor system is all about aesthetics, connectivity and power you can count on for bottle storage. Using water loop cooling, this unit, designed as three separate modules, makes installation easy and adapts to all types of buildings. The innovation that maintains temperatures also reduces thermal shock and air drying.

Split system

The split type wine cellar cooling systems are the perfect solution for a wine cellar located in the kitchen, dining room or living room. Since the compressor is installed away from the cellar, the split system is very quiet, just like the CubeLT.

The split system is cooled with a unit at a much lower temperature than the CubeLT, which can cause a thermal shock on the bottles placed near the evaporator. We do not recommend this type of system for storage, in small display type wine cellars.

Monobloc system (Self-Contained)

The Self-Contained type cooling units represent an adequate solution for a wine cellar that is installed in the basement. The compressor used in this system generates more noise, therefore it is not recommended to install it on the ground floor or very close to a bedroom.

Very affordable, the one-piece system is simple to install, especially if a drain has been provided for the condensate. Like SPLIT-type systems, avoid placing your bottles near the cooling device. This could cause a thermal shock each time the cooling system stops and starts.
