Can anyone identify this plumbing component? Located in the utility closet in a small retail store space. Thanks.

It appears to be a backflow preventer. Used to prevent a cross conection and protect domestic water supplies. RPZ and Conbraco are common brands.....many more no doubt. I understand that they should be tested by qualified individuals once a year.
