A freezing device capable of stable operation at room temperature -60°C using R-404A refrigerant.
This is a freezing system that can rapidly freeze at ultra-low temperatures while preserving cells without damage. By applying it to freezing devices, it achieves high-quality freezing through accelerated freezing speeds. 【Features】 ◆ Energy Saving By actively lowering the condensation pressure below the typical limit and optimizing it to never fall below the necessary pressure value to reach the evaporation pressure, along with operating at a small temperature difference (TD), significant power reduction is possible. ◆ Frost Suppression By operating the temperature difference between the refrigerant evaporation temperature of the unit cooler and the room temperature at around 5°C, it significantly reduces the number of defrost cycles, protecting stored products from the adverse effects of defrosting. ◆ Quality Preservation of Stored Products Operating with a small temperature difference suppresses the driving force (sublimation thrust), preventing the drying of stored products and enabling long-term quality preservation. ◆ Achievement of Ultra-Low Temperatures with Two-Stage Compression Refrigeration Stable operation at -60°C room temperature is possible using R-404A refrigerant. It significantly reduces initial and running costs without using a typical binary refrigeration method at temperatures below -50°C. ■□■□■□■□■□■□■□■□■□■□■□■□ ＝＝＝＝＝ For more details, please contact us＝＝＝＝＝

Company information
Refrigeration, freezing, and freezing equipment are important and essential social infrastructures for food processing, food distribution, and our daily lives. However, each piece of equipment used there is not quantified; it is mostly designed based on experience and safety margins, with operations left to chance. Moreover, there is no consideration for temperature differences or the idea of lowering condensation pressure to operate more energy-efficiently. We have developed a new refrigeration system, the 'η max Refrigeration System,' which breaks away from design methods based on past experience. This system clarifies system capabilities and achieves ultimate high efficiency through a re-evaluation of temperature differences and actively lowering condensation pressure, making it an environmentally friendly new refrigeration system.
