The MDR (EU 2017/745) represents the most stringent regulatory framework for medical devices in the world, demanding enhanced clinical evidence, rigorous post-market surveillance, and greater transparency. Achieving the new standard MDR certification for several series ultra-low temperature freezers and blood bank refrigerators are a testament to the product's robust design, clinical efficacy, and the company's diligent quality management system.


Meling Biomedical frequency conversion dual cooling system ULT Freezer, which built up by two independent refrigeration systems and the dual cooling system offers the highest level of protection, only one single system work independently can maintain the freezer around the -80℃, valuable and irreplaceable samples can always be securely stored with the highest confidence even if the compressor fails.
*Frequency Conversion Cascade ULT Freezer
Meling Biomedical Frequency Conversion Cascade 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. The 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℃ then, during the second stage, cooled down from -45℃ to -86℃. This enables smooth and reliable operation of the individual compressors as they work in a comfort zone.
*-86℃ Target Cooling ULT Freezer
Meling Biomedical Target Cooling ULT freezer that consists of auto cascade cooling technology with nature hydrocarbon refrigerant. It offers high level of protection, refrigeration system in parallel provide dual cooling compressors ensure fast pulling down and door open recovery time, and if one of compressors in system get broken in case,the another compressor can continue working to maintain the temperature at -70℃,to save up the samples inside chamber.
