For Eppendorf, being efficient and green is not a trend, it’s in our nature. Since 1945 we have recognized our place as a global citizen and began our green initiative by building high-quality, long-lasting products. Today, we continue to set new standards with our high-efficiency freezers, among the most energy-efficient ULT freezers on the market. Eppendorf High-Efficiency ULT Freezers minimize operating costs while providing excellent protection for your critical samples. They reduce energy consumption by up to 50 % when compared to other models. This group of freezers provides all of the features of the other freezer models.

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 CryoCube F570h just needs 7.6 KWh/day. This future-oriented instrument class provides consumption levels which are ahead of most competitors within this volume class. The CryoCube F570h (115 V) is certified by ENERGY STAR®.
Besides the sustainability, the focus is on ergonomic aspects. Especially the new door handle of the CryoCube models is 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 High-Efficiency Freezers can be equipped with CO2/LN2 backup systems and a chart recorder. 
When investing in a new ULT freezer, the product price itself is one decision 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.

The temperature range is from -50°C to -86°C.

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 on 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.

› Heat output during final individual unit testing discharges building heating system 
› Plastic and cardboard compactors introduced + waste rebate system in place 
› Local requirements for waste management (collection of electronic waste like circuit boards, recycling via authorized recycling organizations) and internal guide lines 
› Usage of green cooling liquids in Eppendorf ULT freezers for 10 years 
› Packaging parts have increasing share of recycled origin 
› Packaging is more than 99% recycable (wood, cardboard, PE-foil) 
› REACH + RoHS compliant 
› ENERGY STAR® partner 
› Marketing material is printed on FSC certified paper, wherever possible focus on pdf only 
› Shipment by cargo ship to reduce CO2 footprint
