What to Look for in Energy-Efficient Freezers

By Kim McDonald, 25 December 2022

The US Environmental Protection Agency (EPA) has created specifications for energy-efficient refrigerators and freezers for laboratory use. The goal of this program is to make it easy for consumers to identify appliances that will be environmentally friendly by consuming less energy while also saving energy costs for the user. Most manufacturers that are eligible will include the ENERGY STAR® label, making it an easy way to spot freezers that meet these criteria. You can also search an online database to determine whether the unit you’re looking at complies with ENERGY STAR® guidelines.

Understanding Defrost Cycles on Refrigerators and Freezers

By Doran Amos, 04 July 2022

Defrosting is an essential step in maintaining your laboratory refrigerator or freezer to ensure that it continues to provide adequate and stable cooling for your stored items.

Defrosting offers a number of key benefits:

It keeps the evaporator coils frost-free, enabling them to cool the interior of the refrigerator or freezer effectively;
It maintains good airflow in the refrigerator or freezer, so that the air temperature is stable and uniform throughout the inner compartment;
It prevents frost from taking up valuable space within the inner compartment;
It stops damage to sensitive items or components by frost.
