PHCbi Ultra-Low Temperature Freezers: By the Numbers

The development of ultra-low temperature freezers spans decades of progress in component design. From refrigerants and compressors to controllers, cabinet insulation methods and inventory arrangements, manufacturers have attempted to present a best-case scenario for freezer performance based on internal testing, ambiguous publication of data and convoluted comparisons to competitive products. The industry-wide creation of ENERGY STAR criteria for managing independent testing against common performance values has prompted leading ultra-low temperature freezer manufacturers to invest in third-party evaluations of product functionality so that purchasing decisions can be based on reliable data, rather than sales or marketing claims.
