Anheuser-Busch Cos. LLC has been cited by the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) for two repeat and eight serious safety violations following an inspection of its Columbus, Ohio, brewery’s ammonia refrigeration system. Proposed penalties total $92,400.

Commercial refrigeration systems, whether utilized in supermarkets or restaurants, seem to be constantly changing. 

The Food Marketing Institute (FMI) Connect event showcased some of the newest products that those who work in the food sector will more than likely see on a future install or service call.

For this focus on supermarkets and restaurants, The NEWS asked a number of contractors where they are in the mix and where they see the refrigeration sector heading. Here is what they had to say.

The U.S. Environmental Protection Agency (EPA) and U.S. Department of Justice (DOJ) have announced a settlement with Costco Wholesale Corp. in which the company agrees to pay $335,000 in penalties for federal Clean Air Act violations and improve refrigerant management at 274 stores.

The function of an oil reservoir, commonly known as an oil trap, is to prevent large oil slugs from forming. This is accomplished by trapping a small amount of oil in the reservoir or trap and gradually returning it to the compressor.

Contractors hoping for the final word on the newest refrigerants may not have to wait much longer. 

For maximum efficiency, a bank of compressors should be connected to evaporators operating at similar temperatures. From an operational standpoint, cases of different evaporating temperatures can be connected to the rack; however, this causes a substantial energy loss.

Supermarkets in the United States can now get expert help in securing energy-efficiency rebates from utilities. The service is for supermarkets that invest in initiatives to improve energy efficiency but may not collect all the utility rebates for which they qualify, said Abtar Singh, chief executive of Singh360.

On Aug. 4, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and Lennox Intl. Inc. filed a petition asking the U.S. Court of Appeals for the 5th Circuit to review the U.S. Department of Energy’s (DOE) final rule establishing energy conservation standards for walk-in coolers and freezers (WICF).
