Can Quantor chillers be placed outside in the rain?
It depends on the type of Quantor chiller.
The following series cannot be exposed directly to rain: MiniChilly, IceChilly, ModuChilly, Chilly, Chilly Max, MCK, KreyoPack, and SR.
If these models are installed outdoors, a protective shelter is required. The shelter roof should be at least 2 meters above the fan and extend 1 meter around the unit to allow proper airflow and prevent water damage.
All other Quantor chiller series are weather-resistant and can be safely installed outdoors without a shelter, even under rainy conditions.
What is the difference between the MCK series and the Quantor Pro series?
Both the MCK series and the Quantor PRO series offer outstanding cooling performance and reliability. The right choice depends on the application and installation environment.
The MCK series is ideal when a larger buffer tank and an open water circuit are preferred. For example, the MCK 321 (38.6 kW) includes a 300-liter tank, offering greater temperature stability and easier handling – especially suitable for small to medium-sized wineries and breweries.
The Quantor PRO series, on the other hand, features a closed water circuit, which is more energy-efficient and better suited for automated or temperature-sensitive systems. It’s the perfect choice for larger installations or when process precision is critical.
What is the recommended propylene glycol percentage in water for a -10°C outlet temperature?
For a chiller system with a solution outlet temperature of -10°C, the recommended propylene glycol concentration is 33% glycol and 67% water by volume. This ratio provides effective frost protection, stable cooling performance, and optimal heat transfer efficiency.
The best way to verify the glycol-water mixture is by using a refractometer designed for antifreeze solutions. Refractometers intended for sugar measurement (Brix) are not suitable for this purpose.
WTG-Quantor offers high-precision antifreeze refractometers to ensure accurate glycol mixture readings. Please contact our team for product information and pricing.
What are the most important factors affecting a chiller’s cooling capacity?
Several key factors influence the cooling capacity and efficiency of a chiller. Understanding these factors helps ensure optimal performance, energy savings, and system reliability.
1. Ambient temperature and water inlet/outlet temperatures
According to IS 16590 international standards, chillers are rated at 35 °C ambient temperature and 12 °C / 7 °C water inlet/outlet. When the ambient temperature is higher, or the water temperature difference is smaller, the chiller cooling capacity decreases.
2. Installation environment and ventilation
Installing a chiller in a poorly ventilated area limits air circulation and reduces heat dissipation efficiency. Proper airflow around the condenser is essential to maintain stable performance.
3. Condenser cleanliness and air quality
Dust and dirt on air-cooled condensers block heat exchange, forcing the compressor to work harder. Regular maintenance and cleaning preserve chiller performance and lower energy consumption.
For maximum cooling efficiency, always ensure proper installation, good ventilation, and scheduled maintenance in accordance with the manufacturer’s recommendations.

Industry Knowledge & Application Benefits
What happens if wine ferments at too high a temperature?
If wine becomes too warm during fermentation, it can negatively affect the production process. High temperatures may speed up fermentation but often result in the loss of delicate aromas and an unbalanced flavor profile. Yeasts can become stressed or die, causing fermentation to stop and quality to deteriorate. Unwanted off-flavors or faults may develop. This is why precise temperature control is essential for quality and stability of the final product.
Why must wine be cooled during fermentation?
During fermentation, heat is generated as yeast converts sugar into alcohol and carbon dioxide. If the temperature rises too much, delicate aromas can be lost, fermentation can become unbalanced, or the yeast may die. Controlled cooling keeps the temperature at an optimal level, ensuring steady, aroma-preserving fermentation. The result is wines with a clear, harmonious flavor and high quality.

What role does storage cooling play in the maturation of beer, wine, and spirits?
Proper storage cooling plays a crucial role in the maturation, stability, and quality of wine, beer, and alcoholic beverages. After fermentation, the storage and aging phase begins—a decisive period during which flavor, aroma, clarity, and shelf life are shaped. A constant, precisely controlled storage temperature is essential to optimally support the natural maturation process.
Storage Cooling for Beer: Maturation, Clarity, and Flavor
For beer, controlled cooling during storage is particularly important. During maturation, yeast cells break down remaining by-products such as diacetyl (buttery flavor) or acetaldehyde (green apple notes). A stable storage temperature between 4–8 °C ensures that this process proceeds slowly and evenly, without compromising aroma or freshness.
Cold storage also promotes the natural precipitation of haze-forming substances such as proteins, polyphenols, and yeast, resulting in clearer and more visually appealing beer. Carbonation binds more effectively as well, leading to balanced effervescence and a pleasant mouthfeel. For breweries, this means a final product that is not only sensorially stable but also meets high visual quality standards.
Storage Cooling for Wine: Aroma, Structure, and Shelf Life
Precise temperature control during storage is equally critical for wine. Fluctuating or excessively high temperatures can accelerate aging, promote oxidation, and hinder the development of delicate aromas. Uniform storage at around 10–12 °C allows the characteristic notes of red, white, and sparkling wines to develop harmoniously.
In addition, constant cooling preserves the wine’s structure, maintains acid balance, and prevents premature loss of freshness. High-quality wines in particular benefit from slow, controlled aging, which can only be achieved under stable storage conditions.
Storage Cooling for Spirits, Cider, and Mead
Spirits, cider, and mead also benefit from optimal storage conditions. Low, stable temperatures reduce chemical reactions, prevent oxidation, and help preserve aromas and freshness over extended periods. Precise storage cooling directly impacts sensory quality and extends the shelf life of these beverages.
Benefits of Professional Storage Cooling
Consistent quality: Stable temperatures ensure reproducible batches and consistently high product standards.
Optimal aroma development: Cooling allows aromas to mature harmoniously while reducing unwanted by-products.
Clarity and stability: Proteins, yeast, and haze particles settle efficiently, resulting in visual appeal and flavor stability.
Extended shelf life: Controlled storage preserves freshness and longevity.
Economic efficiency: Producers benefit from reduced waste, stable quality, and improved storage capability.
Conclusion
Proper storage cooling is a key quality factor in the production of wine, beer, and alcoholic beverages. It ensures optimal maturation, protects aromas, improves clarity and stability, and extends shelf life. Modern cooling systems enable precise temperature control and are therefore indispensable tools for breweries, wineries, and producers of premium alcoholic beverages. Those who invest in stable, controlled storage ensure that every beverage reaches its full sensory potential and delivers the highest quality to consumers.
What is the significance of temperature in the production of wine, beer, and other alcoholic beverages?
Temperature is one of the most important quality factors in the production of wine, beer, cider, spirits, and all other fermented beverages. Precise temperature control determines how stable the fermentation process is, how cleanly the yeast works, and how intensely aromas, color, and structure develop. Anyone who wants to produce high-quality beverages therefore needs reliable and precisely controllable fermentation and cooling technology.
Excessively high temperatures often lead to unwanted off-flavors, yeast stress, and uncontrolled fermentation. Temperatures that are too low slow down fermentation or bring it to a complete halt. The right temperature window is therefore essential for product quality—whether white wine, red wine, lager beer, ale, cider, or distillation mash.
The right temperature not only influences fermentation, but also maturation, stabilization, and storage. Only constant, hygienically safe, and energy-efficient cooling can protect aromas, reduce microbiological risks, and ensure consistent product quality.
Modern digital control technology—such as the systems from WTG-Quantor—enables highly precise control of tank temperatures, CO₂ output, and process data in real time. This ensures reproducible results, lower energy and operating costs, and maximum process reliability. For winemakers, brewers, distilleries, and the entire beverage industry, professional temperature control is an indispensable part of a quality strategy.
What is the ideal fermentation temperature for white wine and red wine?
The ideal fermentation temperature depends largely on whether white or red wine is being produced and on the chosen fermentation style. For white wine, winemakers often use cool, controlled fermentation. At temperatures around 14 to 16 °C, fermentation progresses slowly and steadily: the yeast converts only about 10 to 15 g/L of sugar per day, equivalent to 4 to 5° Oe. When the temperature is raised slightly to 18 to 20 °C, the process accelerates noticeably, with 20 to 30 g/L of sugar (about 8 to 10° Oe) being metabolized daily. This careful temperature management helps preserve freshness, aroma and balance.
Red wine behaves similarly but is generally fermented at higher temperatures. A moderate fermentation between 20 and 23 °C results in a steady conversion of about 20 to 30 g/L of sugar per day, equal to 8 to 10° Oe. In contrast, a warm fermentation at 25 to 28 °C significantly increases yeast activity, often reaching 50 g/L of sugar per day or more, which corresponds to at least 20° Oe. These higher temperatures not only boost fermentation speed but also enhance the extraction of color, tannins and aromas from the skins – essential for producing structured, full-bodied red wines.
These differences clearly show how strongly temperature influences fermentation and why precise temperature control is crucial for each wine style. By guiding the process carefully, winemakers can achieve more reliable fermentations and higher-quality wines.
What influence does temperature have on the fermentation process?
Temperature is one of the key factors that determine both the progression and the outcome of the fermentation process. It directly affects yeast activity, aroma development, the speed of sugar breakdown, and ultimately the quality of the wine. In general, the rule is: the warmer the fermentation environment, the more active the yeast works – and the cooler it is, the slower and more controlled the fermentation proceeds.
At low temperatures, fermentation remains calm and steady. The yeast converts sugar slowly, resulting in more delicate aromatic expression, which is particularly characteristic of white wines. Cooler conditions promote fruity, clear, and elegant aromas because volatile compounds are better preserved during fermentation.
When the temperature increases, the fermentation process accelerates significantly. The yeast metabolizes more sugar per day, and the wine develops more quickly. At the same time, the extraction of compounds from the grape skins increases – an advantage for red wines, where color, tannins, and structure are essential. However, excessively high temperatures pose risks: yeast stress, unwanted by-products, and loss of valuable aromas.
A stable and well-controlled fermentation temperature is therefore essential. It prevents fermentation problems, protects against off-flavors, and allows the winemaker to precisely shape the desired wine style. Temperature is thus one of the most effective tools for influencing wine quality, character, and expression.
How can I control the fermentation temperature in my winery?
In modern wineries, the most reliable way to control fermentation temperature is through digital control and cooling systems that automatically monitor the entire fermentation process and precisely cool or heat the tanks. The goal is to maintain a stable, optimal temperature inside the tank so the yeast works cleanly and produces the desired aromas.
One of the most efficient solutions is the VinInfo system from WTG-Quantor – a modular digital control, regulation and information system specifically developed for wineries.
