You will get a much more balanced approach from a company that has more than one type of compressor to sell. If all you have to sell is screws....guess what, they are the best compressor for every job ...especially if you want to continue to eat.

I enjoyed working foe many years with a company that could offer screws, recips and centrifugals for a while. It was actually fun to hear some of the "stories" the competitors came up with why you had to use certain type of compressor.

It also helps to have experienced and open minded engineers...but that seems to be something the industrial industry is loosing.

I am currently out of the refrigeration field after 37 years. My choosing due to location and $$$$. I can make a lot more at a large EPC firm.
