The Eppendorf U410 series of ULT freezers minimize operating costs while providing superior protection for your critical samples. Combined insulation based on vacuum insulation panels and polyurethane foam enables extremely low energy consumption (HEF U410). The Premium U410 is based on polyurethane foam insulation.
The series is based on two models:
› Premium U410: 130 mm wall based on polyurethane insulation, “classic” cooling liquids, air-cooling
› HEF U410: 130 mm wall based on polyurethane insulation and vacuum insulation panels, “green” cooling liquids (R290/ R170), air-cooling
The volume is 410 L (14.5 square feet). The temperature range is from -50 °C to -86 °C.
PhysioCare
Besides sustainability, the main focus of our freezers is on ergonomic aspects. Easy closing of the outer door, ergonomic door handle, display on eye-level, or easy-to-clean stainless steel interior are based on the Eppendorf PhysioCare Concept: Safe grip but very light forces needed to open and close the freezer door.
For even higher sample safety, the Eppendorf ULT freezers can be equipped with CO2/LN2 back-up systems and a chart recorder.
Cost of ownership
When investing in a new ULT freezer, the product price itself is only one aspect. Others include the long-term costs of power consumption and the costs of service and spare parts. Keep in mind, a high-quality ULT freezer will do its job in the lab for 10 years or more.
Sample safety
The U410 series is equipped with reliable heavy-duty compressors (2-stage cascade cooling system). Quick pull-down times enable fast re-use after cleaning/defrosting of the instrument. The freezers have short recovery times after opening to provide extra sample safety. For even higher sample safety, the Eppendorf U410 freezers can be equipped with CO2/LN2 back-up systems and a chart recorder. Temperature monitor systems can be used to monitor the freezers remotely.
Sustainability
Sustainability for ULT freezers is a challenge: Maintaining extremely low temperatures of -86 °C for 24 hours a day, 7 days a week needs energy.
By following the epGreen concept, the Eppendorf freezer R&D team developed intelligent solutions where energy savings are combined with durable long-lasting product quality and ergonomic aspects. By using highly efficient technologies, the HEF U410 just needs 8.4 KWh/day. This future-oriented instrument class provides consumption levels which are ahead of most competitors within this volume class.
Eppendorf Ultra-Low Temperature freezers are among the most energy-efficient in the industry, reducing energy consumption by thousands of kilowatt hours over our competition.
Hydrocarbons
In 2014, the European Union announced a ban of all non-hydrocarbon-liquids (EU_517/2014) until 2020.
Hydrocarbons are also known as green or natural gases. The two major representatives are propane and ethane (known as R290 and R170). Based on IEC 60335-2-89, there are no additional safety instructions for using green gases in ULT freezers necessary.
This ban includes all cooling devices except instruments for temperatures below -50°C. Based on this exception, ULT freezers of -86°C can continue to run with HFCs. Still, it makes sense to replace the HFC cooling liquids also for ULTs as global warming needs to be slowed down.
Due to this goal, we at Eppendorf clearly plan to replace all classic cooling ULT freezers within the next years.
Remember 2008?
As being one of the very first movers for green gases at -86°C, Eppendorf has now 10 years of experience in R&D, production, logistics, and service in the field.
In 2008, the (Eppendorf) New Brunswick Premium U570h was one of the very first commercially available ULT freezers driven by green cooling liquids.
