Energy consumption

Centrifugation is based on two major power-consuming steps: temperature management of the chamber and acceleration of the rotor. Active cooling, in general performed by a compressor system, is mandatory for preserving many high-value samples. While a weaker cooling system may save energy, it may put samples at risk due to insufficient temperature control. As a consequence, the experiment may have to be repeated.

To address power consumption, our centrifuges feature various energy-saving functions, tailored to each centrifuge model:

The eco-shutoff function switches off the continuous cooling function of refrigerated models after a period of inactivity (usually after one, two, four, or eight hours), resulting in lower overall energy consumption (e.g., 37% less for Centrifuge 5430 R overnight) and prolonging the compressor’s lifespan.

The standby function switches the centrifuge into sleep mode (e.g., by switching off the display) after a defined period of inactivity.

Reduced weight: The fixed-angle rotors of our multipurpose centrifuges (50 mL conical rotors and bigger) are hollow to reduce their weight. This makes them easier for users to handle as well as reduces power consumption during acceleration as less weight needs to be put in motion.

Optimized design: Most swing-buckets in our multipurpose centrifuges are now round instead of rectangular, leading to lower energy consumption (up to 48% less energy with rotor A-4-72 versus rotor A-4-62 in Centrifuge 5810 R).
