For Eppendorf, being 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 superior 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.

The ratio of the number of storage boxes to energy consumption is higher for chest freezers than upright models. When the chest freezer is opened, the cold air is kept inside. Additional insulated panels cover the inner chamber and increase energy saving. You can store up to 52,000 samples in a CryoCube FC660h. Each CryoCube model is delivered with its own specific certificate. The CryoCube FC660h combines all the power-saving technology of the CryoCube FC660 with additional vacuum insulated panels. It provides the same sample security and ease of use with even less power consumption. The temperature range is from -50°C to -86°C.

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 F660h just needs 8.1 KWh/day. This future-oriented instrument class provides consumption levels which are ahead of most competitors within this volume class. The CryoCube FC660h (208 V) is certified by ENERGY STAR®.

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.

Support the epGreen initiative with your Eppendorf ULT freezer

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.

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.
