How Low-Temperature Systems Work

Refrigerant in Circulation

Our low-temperature systems are designed to generate extremely low freezing temperatures.
Following the principles of refrigeration technology, our cooling systems use a refrigerant from which heat is extracted. The cooled medium can then be used for specific cooling purposes.
Depending on the model, the following substances are used as refrigerants:

Methanol, Ethanol, Therminal D12, Fragoltherm F-12

Water / Glycol, Calcium Chloride

Tyfoxit F 50, Calcium Chloride 30%

The respective carrier medium circulates in a closed loop, where it is continuously cooled by the low-temperature system, then transported to the point of use to release the cold, before returning to repeat the cycle.

The Cooling Process Inside a Chiller System

So far, so good – but how exactly is the refrigerant cooled down using the low-temperature system? ChatGPT fragen

1) Heat Absorption and Evaporation

In the first step of the chiller cycle, the refrigerant absorbs the thermal energy from the heat carrier (often glycol), causing it to evaporate.

2) Compression in the Compressor

Once in gaseous form, the refrigerant enters the compressor, where both pressure and temperature are significantly increased.

3) Heat Rejection to the Environment

In the third step, the heat generated during compression is released to the environment—usually via powerful fans that blow air over a heat exchanger. During this process, the refrigerant condenses back into a liquid.

4) Expansion and Temperature Drop

In the final step, an expansion valve reduces the pressure of the refrigerant back to its initial state, causing a significant drop in temperature. The cycle then begins again.

Low-Temperature Cooling for a Wide Range of Applications and Industries

Low-temperature systems are used across a variety of industries and application areas. Below are some examples highlighting the versatility of our systems:

1 – Low-Temperature Systems for Ground and Soil Freezing: Our low-temperature systems are frequently used for ground and soil freezing in tunnel construction, shaft construction, and excavation pits due to their exceptional cooling performance. They are applied in a specialized civil engineering process where the soil is artificially frozen to solidify and make it impermeable to water. The resulting frozen body gives the ground a high level of stability and protects against water ingress and collapse. This allows construction work to proceed without interruption. The chiller maintains the freeze until the required structural stability can be taken over by the finished construction. Soil freezing is typically carried out at temperatures ranging from –15 °C to –40 °C. Ground freezing is also commonly used for cross-passages in tunnel construction, for enclosing excavation pits under difficult conditions, for underpinning work, for soil sample extraction, or for restoring collapsed or backfilled mine structures.

2 – Cold Storage Rooms for the Production and Storage of Food: Cooling equipment such as refrigerators, freezers, and cold storage rooms play a central role in food refrigeration. They keep food at low temperatures, which vary depending on the product, to slow down bacterial growth and preserve food quality. Proper temperature control is essential to prevent food spoilage and ensure it remains free from pathogens. When it comes to food, cooling temperatures are typically below –18 °C. In this range, chillers with water as a coolant are no longer suitable. Instead, low-temperature systems using water-glycol mixtures—such as polar antifreeze solutions—are used. These refrigerants can operate at temperatures as low as –40 °C. While existing cooling systems may handle the required low temperatures for most of the year, summer months can pose a challenge. With low-temperature rental units from S.O.S Rentals, you can reliably bridge those warmer weeks.

Apart from the examples mentioned, low-temperature systems are also used in the rubber and plastics industry, surface technology, metal processing, as well as in the food, chemical, and pharmaceutical industries, and in plant, machinery, and medical engineering.
