Reduce Lab Infrastructure Cost with the Most Sustainable ULT Freezers in the Industry
With considerably lower power consumption and heat rejection, flexible voltage requirements, reduced footprint, and increased overall system reliability, the use of Stirling Ultracold ULT freezers can simplify and reduce the need for electrical, back-up and HVAC infrastructure. This reduced infrastructure need is a benefit both in the laboratory design phase, as well as during ongoing operation.
Reduced Backup Power Requirements
For researchers, the threat of power failure and loss of priceless specimens is a nightmare scenario. While your lab’s infrastructure may have backup electric power capabilities, those systems are not designed to run indefinitely. Stirling’s low power consumption and peak current reduces your backup power requirements, allowing our freezers to run on backup power sources longer than traditional ULT systems. Cooling systems continuing operation during a power failure can be a critical factor in protecting years of research and investments.
Reduced Laboratory HVAC System Load
Conventional ultra-low freezers use a lot of energy to operate and all this energy is converted into heat―essentially a ULT freezer is a heater in the facility! Therefore, the more ULT freezers you have running in your research facility, the more heat that must be removed by your HVAC system. Stirling Ultracold ULT freezers produce less heat, making it much less likely that the environment around the freezers becomes uncomfortably hot, allowing greater flexibility in where they are placed.
To remove the heat that is produced by ULT freezers, electric power is required to run the air-conditioning systems. Based on ASHRAE guidelines, 1 kWh of electric power used by a freezer will require an additional 0.29 kWh of electric power for the HVAC system. Multiplied by 100s of ULTs operated in a research facility, this represents significant potential savings in ongoing energy use and cost, while also reducing the HVAC system capital cost for the facility.
