“Now Hiring! Freezer Salesman in United States.” Well, there’s a new one for me. Usually at trade shows, somewhere in a booth might be a small sign saying, “Manufacturer representatives wanted.” The exhibitor in question also wanted to make it clear that there were openings for folks willing to bring attention to their line.

A line of ammonia industrial refrigeration packages ranges from motor-compressor combinations on rails to complete rotary screw compressor packages. The NH3 screw compressors are available in 20-300 hp.
