Thermo Scientific™ TDE Series ultra-low temperature freezers, powered by H-drive, feature four upright models, maximizing storage capacity from 30,000 up to 60,000 2mL vials. The TDE Series is a sustainable and reliable solution with ultimate sample security and operational savings for every lab. From our first ULT freezer in 1940 to today, the combined experience of REVCO, Forma Scientific, Jewett, Harris, and other families of products continues to drive our ability to deliver industry-leading innovations that help accelerate science and health care.

• Energy efficient use up to 10% less energy than new prior models and up to 42% less energy than aging prior models
• Save an additional 36–39% energy at a -70°C setpoint

TDE Series ULT freezer models TDE40086FD and TDE60086FD use up to 10% less energy than new prior models TSE400D and TSE600D, respectively (Table 1). The energy savings are even more significant when comparing the TDE Series ULT freezers against 5-year-old models TDE Series models use up to 42% less energy. Aging and the design of the previous models leave them more susceptible to performance degradation, which can come in the form of insulation degradation over time and loss of refrigeration system efficiency. Based on this degradation, quantitative modeling calculations were conducted, which estimate the increased energy consumption for a unit that has been in operation for more than 5 years.
