Zhejiang Heli Refrigeration Equipment Co., Ltd. was established in 2006, focusing on ultra-low temperature refrigeration freezer's research and development, manufacturing, sales, and service

Laboratories storing biological samples often rely on extremely stable cold storage systems. An Ultra Low Temp Freezer is designed to maintain temperatures as low as −80 °C for long-term storage of vaccines, biological samples, and laboratory reagents. In many facilities, an Indu...

Many researchers and lab managers are evaluating whether storing critical materials at -70°C instead of -80°C offers practical advantages without compromising sample integrity. When consulting ultra low temperature freezer manufacturers or comparing laboratory cooling options, on...

Temperature recovery in ultra-cold storage systems — especially when a small laboratory freezer door is opened or a power interruption occurs — is a question many researchers grapple with. Professionals consulting ultra low temperature freezer manufacturers often ask: why does it...
