High Efficiency Freezers
Ultra-low temperature (-80 C) freezers are essential for the storage of reagents, clinical biospecimens, and other materials required for scientific research. However, -80 freezers have extensive energy and cooling requirements to support their operation. This is particularly true of older -80 models:
- A typical -80 that is 7 years of age or older requires 20-32 kWh/day in energy to run (as much as the average NY household)
- Older -80s produce approximately 3000 BTU/hr in heat (equivalent to running a small space heater 24 hours per day)
- New, energy efficient -80 models utilize over 66% less energy and generate heat at levels less than 50% of the ULTs 7 years of age and older
Preferred -80 Model
Based on these data, the VP&S Office for Research is encouraging PIs to purchase energy-efficient -80 models when replacing old -80 units or making additions to their freezer inventory. To assist with this process, Columbia Procurement has negotiated for a competitive, discounted price to purchase a preferred, highly-efficient -80 model. These freezers are also pre-installed with the preferred campus freezer monitoring system. Laboratories can take advantage of the discounted price by referencing the quote provided below.
