What is a Free Cooling Chiller?
The ChillerOne free cooling chiller is an energy-saving refrigeration device specially designed for cold climates. It mainly utilizes the cold air in winter or low-temperature environments as a natural cold source.
When the outdoor temperature drops below the required cooling water temperature, our chiller system will automatically shut down the high energy-consuming compressor and only operate the water pump and fan to enable the circulating water to exchange heat with the cold air through a special heat exchanger, thereby achieving cooling.
This design can significantly reduce the energy consumption of the compressor and your operating costs, which is particularly suitable for industrial cooling and other scenarios in cold regions such as Russia, Northern Europe, and Canada.

Features of ChillerOne Free Cooling Chiller
Our unit is equipped with an intelligent control system that can monitor the ambient temperature and water temperature in real time and automatically switch between compression refrigeration and natural air cooling modes. When it is cold enough outside, it will automatically activate the natural cooling mode first to maximize energy savings for you.
In the natural cooling mode, the free cooling chiller is essentially an efficient heat exchanger. It only uses the fan to drive the air, which can directly remove the heat in the process circulating water, thus completely avoiding the high energy consumption operation of the compressor in cold seasons and significantly saving your operating costs.
By maximizing the utilization of natural cold sources, the comprehensive energy efficiency ratio of our free cooling chillers in cold climates is much higher than that of traditional chillers. Although the initial investment may be relatively slightly higher, the cost savings in its long-term operation are extremely significant.
Because it can achieve free cooling in low-temperature environments, we usually use ethylene glycol antifreeze as the circulating medium and equip it with precise water temperature monitoring and control to prevent ice formation inside the heat exchanger in free cooling mode, ensuring the safety and reliability of the system.
Reliable Certification
Our free cooling chiller is ISO and CE certified, adopting energy-saving design to deliver efficient cooling and cut operational costs greatly.

The Working Principle of a Free Cooling Chiller
The ChillerOne naturally cooled chiller efficiently utilizes the ambient low-temperature air as the cold source. Its core working principle is to automatically switch between two modes based on the relationship between the outdoor ambient temperature and the required cooling water temperature.
- Free Cooling Mode
When the outdoor temperature is low enough, our chiller control system will completely shut down the compressor and only operate the circulating water pump and fan. The return water flows through the heat exchanger inside the unit, where the low-temperature air directly takes away the heat to achieve cooling. This process does not start the refrigeration cycle and has extremely low energy consumption.
- Traditional Cooling Mode
When the outdoor temperature rises and the natural cooling conditions cannot be met, our chiller system will automatically switch to the traditional cooling mode. The compressor starts and resumes the complete refrigerant cycle, including evaporation, compression, condensation and expansion, and actively cools by consuming electrical energy.
ChillerOne chillers precisely determine and switch cooling modes through an intelligent control system, maximizing the utilization of outdoor cooling capacity in cold seasons or regions, thereby significantly reducing operational energy consumption. They are particularly suitable for areas with long winters and low temperatures.
The Advantages of Using a Free Cooling Chiller
Reduce Operational Energy Consumption and Costs
During the cold season, our units can shut down the high energy-consuming compressors and rely solely on the operation of the fans and water pumps. By directly using the free cold air from the environment for cooling, this can significantly reduce electricity bills. Especially in cold regions, its comprehensive energy-saving effect throughout the year is remarkable, and the payback period of investment is short.
Reduce Equipment Wear
As the compressor stops running for a long time in the free cooling mode, this not only reduces the mechanical wear and failure rate of the compressor, extends the service life of the core components, but also reduces the risk of shutdown caused by compressor failure, which improves the operational reliability of your entire cooling system.
Easy to Install
The ChillerOne free cooling chiller eliminates the need for cooling towers, water treatment systems and a large amount of cooling water required by traditional water-cooled units, which avoids problems such as the installation of cooling towers. Its system structure is more concise, and it is also more convenient for you to install and maintain.
Achieve Precise Temperature Control
Our unit is equipped with an advanced intelligent control system that can precisely switch between different cooling modes based on load requirements and ambient temperature. Even in extremely cold weather, you can ensure that the water temperature of the process circulation remains stable within the set range by adjusting the fan speed or enabling auxiliary heating to meet the strict requirements of your industrial production.
Environmental Friendliness
In addition to indirectly reducing carbon emissions through energy conservation, ChillerOne free cooling chillers also directly avoid the evaporation consumption of cooling water and the use of chemical water treatment agents. This not only saves precious water resources but also significantly reduces the impact on the water environment, which makes it an environmental cooling solution.
Precautions for Choosing a Free Cooling Chiller
Assess Climate Suitability
The energy-saving benefits of naturally free cooling chillers are directly related to the time during which natural cooling can be utilized. Only in areas where the natural cooling mode operates for a sufficient period of time can its significant energy-saving advantages offset your relatively high initial investment.
Anti-Freezing Considerations
In natural cooling mode, the liquid flowing through the heat exchanger may freeze due to low temperatures. You must choose antifreeze with a sufficiently low freezing point, such as ethylene glycol solution, as the circulating medium and ensure that the internal pipelines, water pumps, valves and other components of the unit are compatible with this medium. Meanwhile, you can also improve the low-temperature anti-freezing protection function, such as low-temperature alarm or auxiliary heating, etc.
Installation Precautions
The ChillerOne free cooling chiller should be installed in a location with smooth air circulation and easy access to low-temperature air. You must ensure that there is no air flow short circuit between the air inlet and the air outlet, and leave sufficient maintenance space. In addition, you also need to assess the noise it generates during winter operation and take sound insulation measures if necessary
Whether the System is Compatible
You need to assess whether our unit is compatible with the existing chilled water circulation system. By designing the hydraulic stability and water temperature transition during mode switching, the stability of the refrigeration process affected by water pressure or water temperature fluctuations caused by mode switching can be avoided.
Our unit is equipped with an intelligent control system that enables seamless and smooth mode switching. At the same time, the water temperature fluctuation can be controlled within ±0.5℃, which fully meets the temperature control requirements of the vast majority of industrial production, ensuring the continuous and stable operation of your production process.
No. Our integrated design is similar to the interface of traditional chillers and can be directly connected to the existing chilled water system. In addition, as the compressor does not operate for a long time in winter, the wear and tear of the main wearing parts is reduced, and your maintenance cost is also lower.
If the average temperature in your local area is high or the project budget is tight and the electricity price is low, its energy-saving effect will be relatively limited for you. Our professional technical team can provide you with selection evaluation.
Supported. Our system can flexibly add machine modules according to your production capacity growth needs. All systems are intelligently scheduled by a unified control system to achieve capacity expansion without affecting your existing production.
