Exciting News from Zhongke Meiling: -86℃ ULT Freezers have passed the Energy Star V2.0 Testing，A Leap in Sustainability and Efficiency
In an era where sustainability and energy efficiency are paramount, Zhongke Meiling has once again demonstrated its commitment to innovation and environmental stewardship. The company’s flagship product, the Twindrive and Cascade series -86℃ Ultra-Low Temperature (ULT) Freezer, has recently earned the prestigious ENERGY STAR V2.0 testing—a testament to its cutting-edge design and superior energy performance. This milestone not only underscores Zhongke Meiling’s leadership in the ultra low temperature storage industry but also aligns with global efforts to reduce carbon footprints and operational costs for laboratories, biobanks, and research institutions.
Why ENERGY STAR Matters
The ENERGY STAR program, administered by the U.S. Environmental Protection Agency (EPA), sets rigorous standards for energy efficiency across appliances.To qualify, products must meet strict criteria for energy consumption, thermal performance, and environmental impact.
A traditional ULT freezers operating between -70°C and -80°C consume around 16-22 Kwh of electricity per day, making them extremely energy intensive and costly to run. Comparing to this, why not to choose a -86℃ ULT freezer which allows to operate on less than 10Kwh of electricity daily, that is obviously 50% less . The -86℃ ultra-low temperature freezer from Zhongke Meiling, having successfully passed the Energy Star V2.0 testing, not only showcases exceptional refrigeration performance but also underscores its commitment to environmental sustainability. These remarkable freezers excels in reducing energy consumption, truly can make the daily consumption around 8Kwh, making it a wise choice for those seeking to minimize their carbon footprint while maintaining optimal efficiency.
Key Features of Zhongke Meiling’s -86℃ ULT Freezer
The -86℃ ultra-low temperature freezer is specifically designed to meet the rigorous demands of scientific research, pharmaceutical storage, and vaccine preservation. Its ability to maintain extremely low temperatures ensures the integrity and longevity of sensitive biological samples and pharmaceuticals, making it an essential utility in laboratories and medical facilities.
Twindrive-86℃ Ultra Low Temperature Freezer built up by two independent refrigeration systems and the Dual Cooling System offers the highest level of protection, if one system unexpectedly fails the other can maintain the freezer around the-80C. Valuable and irreplaceable samples can always be securely stored with the highest confidence even if the compressor fails. The green or natural gases used are future proof and have a very low Global Warming Potential (GWP). This is also supported by European Union Regulation (EU_517/2014). This series using green gases fulfill these conditions for safe usage. Also R170 and R290 follow SNAP compliant in United states as natural hydrocarbon refrigerants, and foaming agent we used for chamber as environmental friendly. What’s more, it adopted with inverter technology with adaptive control is designed to detect high and low usage patterns, adjust compressor speeds, and reduce energy without compromising protection,The ENERGY STAR certified are designed to meet the highest standards in reliability and energy saving.
Cascade series ULT freezer that consists of two stages cascade cooling technology with absolute hydrocarbon refrigerant, which are R290 and R170 as natural gas.The inverter compressors programmed to help energy savings under long period preservation or provide fast temperature recovery while frequently door open to maintain specimens liveness. It Equipped with two-stage inverter technology compressor systems with adaptive control is designed to detect high and low usage patterns, adjust compressor speeds, and reduce energy,first stage is cooled down to -45 °C then, during the second stage, cooled down from -45 °C to -86 °C. This enables smooth and reliable operation of the individual compressors as they work in a comfort zone.When using just one compressor, or even a Stirling engine, to cool down from +20 °C room temperature to -86 °C, more than 100 °C must be spanned in a single step. The 2-stage system is a more durable approach.The ENERGY STAR certified are designed to meet the highest standards in reliability, sustainability and temperature management, inverter technology with adaptive control is designed to detect high and low usage patterns, adjust compressor speeds, and reduce energy without compromising protection.
Join the Energy Efficiency Revolution
The validation that the -86℃ ultra-low temperature freezer has successfully passed the Energy Star V2.0 testing speaks volumes about its energy efficiency and effectiveness in providing reliable cooling solutions. For laboratories and pharmaceutical companies looking for advanced storage solutions, these freezers represents an ideal choice that meets the dual goals of performance and sustainability. Embracing such technology not only enhances operational efficiency but also aligns with a broader commitment to environmental responsibility.
