High Efficiency Freezers
Ultra-low temperature (-80°C) freezers are utilized by most scientific research laboratories and are essential for the storage of reagents, clinical biospecimens, and other materials. They are also one of the most energy-intensive pieces of equipment utilized in laboratories. In addition to directly consuming high amounts of electricity, -80°C freezers also reject large amounts of heat that burden air conditioning and exhaust systems. This is particularly true of older -80°C models:
- A typical -80°C 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 -80°Cs produce approximately 3000 BTU/hr in heat (equivalent to running a small space heater 24 hours per day)
- New, energy efficient -80°C models utilize over 66% less energy and generate heat at levels less than 50% of the -80°Cs 7 years of age and older
Preferred -80°C Model
Based on these data, the VP&S Office for Research is encouraging PIs to purchase energy-efficient -80°C models when replacing old -80°C 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°C model. Product information about this high-efficiency -80°C model can be found here. Published performance data comparing several high-efficiency -80°C models can be found here. 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.
